    ACTION: Advance notice of proposed rulemaking.

    SUMMARY: The Food and Drug Administration (FDA) is considering 
    proposing to amend its regulations to include criteria under which 
    certain additional over-the-counter (OTC) drug active ingredients, 
    indications, dosage forms, dosage strengths, routes of administration, 
    and active ingredient combinations (hereafter referred to as 
    ``conditions'') may become eligible for inclusion in the OTC drug 
    monograph

    system. The proposed criteria would address how OTC marketing 
    experience in the United States or abroad could be used to meet the 
    statutory definition of marketing ``to a material extent'' and ``for a 
    material time'' to qualify a specific OTC drug condition for 
    consideration under the OTC drug monograph system. Under the approach 
    being considered, once an OTC drug condition qualified for 
    consideration in an OTC drug monograph it would be evaluated for 
    general recognition of safety and effectiveness in accordance with the 
    FDA regulations. The decision on whether to propose such regulations 
    will be based, in part, on information and comments submitted in 
    response to this advance notice of proposed rulemaking. The agency is 
    open to approaches other than those identified in this document. FDA is 
    specifically soliciting a broad range of comments to help it decide 
    whether and how to propose amending its regulations to include 
    eligibility criteria for considering additional conditions in the OTC 
    drug monograph system.

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
    A. History
    
    1. Historical Development of the OTC Drug Monograph System
        Since the passage of the Federal Food, Drug, and Cosmetic Act (the 
    act) in 1938, submission of a new drug application (NDA) has been 
    required before marketing a new drug. Under the 1938 act, an applicant 
    who submitted an NDA for approval had to show that a drug product was 
    safe for human use. The 1962 amendments to the act added the 
    requirement that the drug be effective, as well as safe, for its 
    intended uses.
        Not all drugs are considered ``new drugs'' for which premarket 
    approval is required. A drug is not a new drug if: (1) It is generally 
    recognized as safe and effective under the conditions of use for which 
    it is labeled and (2) it has been used to a material extent and for a 
    material time under those conditions (see section 201(p) of the act (21 
    U.S.C. 321(p))).
        To ensure that all drugs marketed in the United States met the 
    act's requirements for efficacy imposed under the 1962 amendments, the 
    agency undertook a review of all the drugs approved for marketing 
    before 1962 on the basis of safety only, i.e., all products approved 
    between 1938 and 1962. In 1966, FDA contracted with the National 
    Academy of Sciences-National Research Council (NAS-NRC) for a review of 
    these drugs, which were covered by ``safety'' NDA's. Thirty panels of 
    experts examined the efficacy, by class or therapeutic category, of all 
    drugs covered by these approved ``safety'' NDA's. The panels considered 
    factual information from scientific literature, reports from 
    manufacturers containing the best evidence in support of their drug 
    efficacy claims, and information provided by FDA and other sources. The 
    NAS-NRC panels related their conclusions to FDA, and the agency 
    reviewed their evaluations by a procedure known as the Drug Efficacy 
    Study Implementation (DESI) program and made efficacy determinations 
    for the drug products.
        Of the approximately 3,900 drugs that NAS-NRC reviewed, about 400 
    were OTC drugs. These OTC drugs were handled under the DESI program, 
    and FDA classified some of these drugs as lacking sufficient evidence 
    of safety and/or effectiveness and ordered their removal from the 
    market (see Sec. 330.12 (21 CFR 330.12)). In most cases, when deferral 
    of implementation led to no significant risk to the public health, 
    conclusions regarding the OTC drugs' safety and efficacy were deferred 
    to a separate OTC drug review that FDA initiated in 1972.
        In the Federal Register of May 11, 1972 (37 FR 9464), FDA 
    established the OTC drug monograph system (currently in part 330) (21 
    CFR part 330). The system was established to evaluate the safety and 
    efficacy of all OTC drug products marketed in the United States before 
    May 11, 1972, that were not covered by NDA's, and all OTC drug products 
    covered by ``safety'' NDA's that were marketed in the United States 
    before the enactment of the 1962 drug amendments to the act. The OTC 
    drug review was set up to evaluate OTC drugs by designated categories 
    or classes (e.g., antacids, skin protectants), rather than on a 
    product-by-product basis, and to develop ``conditions'' under which 
    classes of OTC drugs are generally recognized as safe and effective and 
    not misbranded.
        FDA publishes these conditions in the Federal Register in the form 
    of OTC drug monographs, which consist primarily of active ingredients, 
    combinations of active ingredients, labeling, and other general 
    requirements. Final monographs for OTC drugs that are generally 
    recognized as safe and effective and not misbranded are codified in 
    part 330. Manufacturers desiring to market a monographed condition need 
    not seek clearance from FDA before marketing.
    2. Statutory Requirements Relating to a Drug's Eligibility Under the 
    OTC Drug Monograph System
        Only drugs that are not new drugs may be covered by a monograph. As 
    stated above, to market a new drug, an NDA must be submitted to and 
    approved by FDA before marketing. The term ``new drug'' is defined, 
    under section 201(p) of the act (21 U.S.C. 321(p)), as:
         (1) Any drug * * * the composition of which is such that such 
    drug is not generally recognized, among experts qualified by 
    scientific training and experience to evaluate the safety and 
    effectiveness of drugs, as safe and effective for use under the 
    conditions prescribed, recommended, or suggested in the labeling 
    thereof, * * * or
        (2) Any drug * * * the composition of which is such that such 
    drug, as a result of investigations to determine its safety and 
    effectiveness for use under such conditions, has become so 
    recognized, but which has not, otherwise than in such 
    investigations, been used to a material extent or for a material 
    time under such conditions.
        The courts have interpreted section 201(p) of the act to mean that 
    to avoid new drug preapproval requirements, the drug product must be 
    generally recognized as safe and effective and must have been used to a 
    material extent and for a material time under the labeled conditions of 
    use. (See, e.g., Weinberger v. Hynson, Westcott & Dunning, Inc., 412 
    U.S. 609, 631 (1973); Premo Pharmaceutical Laboratories, Inc. v. United 
    States, 629 F.2d 795, 801-802 (2d Cir. 1980).) To satisfy the 
    requirements of section 201(p)(2) of the act for a particular drug, 
    both the time and the extent of marketing of the drug must be shown to 
    be material. In addition, as discussed in section I.A.3. of this 
    document, the agency has interpreted the use required by section 
    201(p)(2) to mean use in the United States.
    3. Application of the Statutory Requirements for Determining 
    Eligibility in the OTC Drug Monograph System
        As stated above, FDA considered in its review all active 
    ingredients in OTC drug products that were on the U.S. market as of May 
    11, 1972, when the
    
    [[Page 51627]]
    
    review began, regardless of specific marketing history.
         The agency has recognized that the ``newness'' of an OTC drug 
    product can occur for several reasons. The newness may arise by reason, 
    among other reasons, of the drug product's new ingredient, indication, 
    dosage form, dosage strength, route of administration, or combination 
    of active ingredients. (See 21 CFR 310.3(h).)
        Periodically, questions would arise about whether certain 
    conditions of use introduced after May 11, 1972, caused the products to 
    be ``new'' drugs requiring marketing approval under NDA's, or whether 
    the products could be eligible for consideration in the OTC drug 
    monograph system. The agency determined the eligibility of these 
    conditions individually on the basis of whether they had been marketed 
    to a material extent and for a material time. Examples of the agency's 
    past material extent and material time eligibility determinations are 
    discussed below.
        The agency has taken the position that the marketing of an OTC drug 
    in a foreign country, but never in the United States, does not satisfy 
    the requirement of marketing to a material extent and for a material 
    time. In the Federal Register of December 12, 1980 (45 FR 82014), the 
    agency concluded that menfegol, a vaginal contraceptive active 
    ingredient marketed abroad for a number of years as an OTC drug 
    product, was a new drug within the meaning of section 201(p) of the act 
    because it had never been marketed as a drug in the United States. 
    Likewise, in the Federal Register of November 16, 1988 (53 FR 46204 at 
    46248), the agency stated that it considered a lysine salt of aspirin, 
    an internal analgesic active ingredient, to be a new drug within the 
    meaning of section 201(p) of the act. This ingredient had been marketed 
    OTC abroad but had never been marketed as a drug in the United States.
        The agency also has declared new dosage strengths to be ineligible 
    for the OTC drug review. In 1984, FDA denied a citizen petition 
    requesting that the agency reopen the administrative record for the 
    rulemakings for OTC internal analgesic and menstrual drug products to 
    consider a new dosage strength of ibuprofen (200 milligrams (mg)) (Ref. 
    1). The agency denied the petition, stating that the 200 mg dosage 
    strength had not been used to a material extent and for a material time 
    in the United States and, therefore, was considered a ``new drug'' that 
    could not be lawfully marketed in the United States without an approved 
    NDA.
         In the Federal Register of July 19, 1983 (48 FR 32872 at 32873), 
    the agency stated that a labeled indication that had never previously 
    appeared on any marketed OTC drug product was not eligible for 
    consideration in the OTC drug monograph system. The agency determined 
    that products claiming ``to minimize or prevent inebriation'' had not 
    been marketed to a material extent and for a material time in the 
    United States and declared that all products with sobriety aid 
    indications were new drugs within the meaning of section 201(p) of the 
    act.
        Similarly, FDA concluded that an ingredient that had not previously 
    been marketed in the United States for a specific indication is not 
    eligible for consideration in the OTC drug monograph system. In the 
    Federal Register of October 13, 1983 (48 FR 46694 at 46695), the agency 
    stated that potassium sorbate had not been marketed to a material 
    extent and for a material time in the United States as a vaginal drug 
    product active ingredient and, therefore, was considered a new drug 
    within the meaning of section 201(p) of the act for such use.
        More recently the agency has found that avobenzone, a sunscreen 
    ingredient, is eligible for review in the OTC drug monograph system (61 
    FR 48645, September 16, 1996). Avobenzone has been continuously 
    marketed OTC in the United States under NDA's for approximately 8 years 
    and subject to the NDA adverse events reporting requirements. Over 5 
    million units of avobenzone-containing products have been sold in the 
    United States.
        In applying the material extent and material time provision of 
    section 201(p)(2) of the act to determine whether certain conditions 
    were eligible for consideration in the OTC drug monograph system, FDA 
    has also applied a ``substantially indistinguishable'' standard. This 
    standard was first articulated in a September 23, 1977, letter to a 
    drug manufacturer concerning its submission regarding the ingredient 
    potassium nitrate for use as an OTC tooth desensitizing agent (Ref. 3). 
    The letter stated that an ingredient may meet the act's marketing 
    provision of section 201(p)(2) of the act without having been marketed 
    under the precise conditions of use sought, provided the ingredient had 
    been marketed to a material extent and for a material time under other 
    conditions of use that, although different, are ``substantially 
    indistinguishable'' in all respects relevant to the drug's safety and 
    effectiveness. Specifically, the conditions of use would have to be 
    similar enough that experts could reliably conclude that knowledge 
    about the safety and effectiveness of a drug derived from experience 
    with its use under one set of conditions could be applied to the 
    evaluation of the safety and effectiveness of its use under the 
    conditions for which approval was being sought.
    
    B. Petitions and Comments
    
        The agency has received one comment and nine citizen petitions 
    (Refs. 4 through 13) requesting that it accept foreign marketing data 
    to demonstrate that specific conditions of use have been marketed to a 
    material extent and for a material time and, on that basis, to consider 
    these conditions in the OTC drug review. If the agency were to change 
    its current policy and accept such data, this would allow such 
    conditions to be considered in the OTC drug monograph system.
        This advance notice of proposed rulemaking addresses the primary 
    issue raised in these petitions regarding acceptance of foreign 
    marketing experience to demonstrate that OTC drug conditions have been 
    marketed to a material extent and for a material time. The agency will 
    provide separate responses to the petitions at a later date.
    
    II. Criteria Under Consideration for Demonstrating Marketing to a 
    Material Extent and for a Material Time
    
        Currently, the OTC drug regulations in part 330 do not define: (1) 
    Eligibility requirements for consideration in the monograph system or 
    (2) what constitutes marketing to a material extent or for a material 
    time. However, FDA's policy has been not to consider foreign marketing 
    experience for purposes of determining whether a drug has been marketed 
    to a material extent or for a material time. The agency is considering 
    a proposed rule containing criteria for defining material extent and 
    material time under which an OTC condition with or without U.S. 
    marketing experience could be considered in the OTC drug monograph 
    system. As previously indicated, FDA defines a condition as any active 
    ingredient, indication, dosage form, dosage strength, route of 
    administration, active ingredient combination, or any combination of 
    these conditions.
        In developing these criteria, FDA is considering three basic 
    issues: (1) Nature of use, (2) time used (material time), and (3) 
    extent of distribution (material extent).
         These issues are discussed below and the agency is seeking comment 
    on each.
    
    [[Page 51628]]
    
    A. Nature of Use
    
        When determining if a foreign OTC drug product condition has been 
    marketed to a material extent and for a material time, FDA is 
    particularly concerned about certain variables presented by foreign 
    marketing experience. In the Federal Register of February 22, 1985 (50 
    FR 7452), the agency amended its regulations pertaining to foreign 
    clinical studies in Sec. 314.106 (21 CFR 314.106) to provide 
    specifically for the acceptance of foreign data in NDA's. In doing so, 
    the agency acknowledged the high quality of drug testing from a number 
    of foreign research institutions, but recognized that foreign data 
    present three unique issues not associated with domestic data: (1) 
    Medical, genetic, and cultural differences between countries; (2) lack 
    of FDA's familiarity with foreign clinical investigators and 
    facilities; and (3) FDA's inability to conduct on-site verification of 
    many foreign studies (see 50 FR 7452 at 7483). To address these 
    concerns, the agency specified three criteria in Sec. 314.106 that must 
    be met before the agency can approve an NDA based solely upon foreign 
    data: (1) The foreign data must be applicable to the U.S. population 
    and U.S. medical practice; (2) the studies must be performed by 
    clinical investigators of recognized competence; and (3) the data can 
    be considered valid without the need for on-site inspection by FDA or, 
    if FDA considered such an inspection necessary, FDA would be able to 
    validate the data through on-site inspection or other means. 21 CFR 
    312.120 contains additional acceptance criteria for foreign clinical 
    studies not conducted under an IND.
        The agency recognizes that foreign marketing experience, like 
    foreign clinical data, presents several unique issues not associated 
    with U.S. marketing data: (1) Medical, genetic, or cultural differences 
    between a foreign country's population and the U.S. population may 
    affect the way OTC drug products are used and, in turn, the medical 
    outcomes; (2) the diversity in the way drug products are marketed in 
    foreign countries (e.g., prescription, OTC general sales, behind the 
    counter, sold by a pharmacist (third class of drugs)) may make it 
    difficult to demonstrate suitability for OTC sale in the United States; 
    and (3) many foreign countries' marketing approval processes and 
    adverse event reporting requirements would make it difficult to 
    determine whether adverse reactions to the OTC drug product have been 
    experienced. Therefore, in establishing what constitutes use for a 
    material time and to a material extent, FDA must determine whether to 
    impose any limitations on types of marketing experience it would 
    consider relevant to whether the drug should be marketed OTC in the 
    United States under a monograph system. The following discussion 
    focuses these issues on limitations related to: (1) Where the drug is 
    marketed and its relevance to the U.S. population; (2) the type of 
    adverse reporting system that exists in the countries in which the drug 
    has been marketed and the nature of any adverse event reports 
    associated with the drug; and (3) the nature of that marketing 
    experience, such as whether the drug has been marketed by prescription, 
    OTC, or as a third class of drugs that can be sold only by a 
    pharmacist. This marketing experience would also be based on consistent 
    active ingredients and product formulations that do not require 
    critical manufacturing controls and/or involve complex bioavailability 
    questions.
    1. Where the Drug is Marketed
        Because of the concerns discussed above, one petition suggested 
    that the agency limit its consideration of OTC marketing experience to 
    the export countries identified in section 802(b)(4)(A) of the act (21 
    U.S.C. 382(b)(4)(A)), as added by the Drug Export Amendments Act of 
    1986 (Pub. L. 99-960). Section 802(b)(4)(B) of the 1986 amendments 
    listed four requirements related to the approval of drugs in foreign 
    countries. These requirements were similar to requirements in the 
    United States. Congress declared that 21 countries met these 
    requirements and were listed in section 802(b)(4)(A) of the act for 
    purposes of allowing them to receive for general marketing the export 
    of certain unapproved new drugs from the United States. In April 1996, 
    Congress amended section 802 of the act (Pub. L. 104-134) to, among 
    other things, add additional countries to the list, allow the Secretary 
    of Health and Human Services to add additional countries that meet 
    certain requirements described in new section 802(b)(1)(B) of the act 
    (formerly section 802(b)(4)(A)), and allow the export of certain 
    unapproved drugs from the United States to any country if the drug 
    complies with the laws of that country and has valid marketing 
    authorization by the appropriate authority in one of the listed 
    countries, and certain other conditions are met, as described in the 
    new sections 802(f) and 802(g).
        Although the listed countries may have similar statutory or 
    regulatory requirements to those of the United States, other countries 
    may also have acceptable marketing and approval processes. The agency 
    requests specific comment on whether OTC marketing experience should be 
    considered solely from countries listed or designated under the new 
    section 802(b)(1) of the act or whether experience that meets certain 
    broader criteria should be considered.
    2. Adverse Event Reporting
        For the agency to rely on adverse event information in assessing 
    the safety of the condition in OTC marketing and use, the adverse event 
    information would have to be collected in a country with a drug 
    marketing approval process and postmarketing surveillance system that 
    identifies serious and/or important adverse events associated with the 
    condition's use.
        To assist in making the determination regarding whether a condition 
    has met the requirements of marketing for a material extent and for a 
    material time, the agency is considering requiring submission of the 
    following information: (1) A description of each country's system for 
    identifying adverse events, especially those found in OTC marketing 
    experience, including method of collection if applicable; (2) all 
    serious and important adverse event reports from every country where 
    the condition has been or is currently marketed (whether prescription 
    or OTC); and (3) a list of all countries in which the condition has 
    been withdrawn or in which marketing has been restricted for reasons 
    related to safety or effectiveness, or for any other reason, and a 
    description of these reasons.
        The agency believes that prescription as well as OTC adverse event 
    reports for the condition should be required to be included in an 
    eligibility data submission because data on prescription adverse events 
    may provide useful information for evaluating the safety of the 
    condition for U.S. OTC drug use. The agency also believes that 
    information regarding adverse events associated with other doses 
    (higher or lower) or different indications associated with the 
    condition marketed as a prescription drug product would be useful for 
    determining the safety of the condition for OTC use. This information 
    could result, for example, in different labeling or a different dosing 
    regimen or could even suggest that the marketing of the condition under 
    an OTC drug monograph would be inappropriate.
    3. Nature of Marketing Experience
        Because the criteria under consideration are to determine 
    eligibility for consideration in the OTC monograph review, FDA must 
    consider
    
    [[Page 51629]]
    
    whether marketing experience as a prescription drug will be considered 
    or whether to limit the marketing experience to OTC marketing 
    experience. FDA is considering limiting eligibility to those conditions 
    (as defined previously) that: (1) Have been marketed for direct OTC 
    purchase by consumers; and (2) are not limited to prescription use in 
    the United States.
        Under existing procedures in 21 CFR 310.200, conditions may attain 
    OTC status in one of two ways:
        a. As a new drug. A proposal may be initiated by the Commissioner 
    of Food and Drugs if it is determined that agency requirements are not 
    necessary for the protection of the public health, or by any interested 
    person through the filing of a petition, NDA, or supplemental NDA. A 
    drug switched to OTC status under these provisions remains a ``new 
    drug'' unless it meets each of the necessary conditions under section 
    201(p)(1) and (p)(2) of the act for a drug not to be regarded as a new 
    drug.
        b. As a monograph drug. Through the OTC drug monograph system by 
    either: (1) Recommendations made by an OTC advisory review panel or 
    committee, (2) requests from interested parties (usually in the form of 
    a data submission), or (3) initiated by the agency in an OTC drug 
    monograph.
        When the OTC drug review began, it was designed to address OTC 
    marketing conditions that were already on the market in the United 
    States. The agency permitted the OTC advisory panels to consider 
    prescription to OTC switches and recommend OTC use for prescription 
    drugs whose safety and efficacy for OTC use they believed had been 
    demonstrated in the U.S. population through prior marketing experience.
        Since the completion of the first phase of the OTC drug review 
    (i.e., the OTC advisory review panels' evaluations and publication of 
    their reports), the majority of drug manufacturers have elected to 
    pursue switches from prescription to OTC status under the new drug 
    procedures. The agency considers this mechanism appropriate because the 
    data provided by an NDA, including adverse event reports, manufacturing 
    controls, and bioavailability data where applicable, provide useful 
    information during the transition from prescription to OTC marketing 
    status. In addition, the mandatory reporting of adverse events under an 
    NDA is important to the agency to monitor safe and effective OTC use 
    once a switch has occurred.
        Currently, no adverse event reporting requirements exist for drugs 
    in the OTC drug monograph system. In a future issue of the Federal 
    Register, the agency intends to propose to establish an adverse event 
    reporting system for OTC monograph drugs. However, at this time, the 
    agency believes that the transition from prescription to OTC status is 
    best accomplished by first requiring an OTC drug product to be marketed 
    under an NDA. After a switch occurs under an NDA and sufficient 
    marketing experience is obtained or an adverse event reporting system 
    is in place for OTC monograph drugs, FDA would be willing to include 
    switched drugs in an OTC drug monograph. If and when an adverse event 
    reporting system for OTC monograph drugs is established, this system 
    would better support the use of OTC drug monographs for future 
    prescription to OTC switches that do not require critical manufacturing 
    controls for safe and effective use.
        At this time, the agency does not believe that the criteria for 
    determining material time and material extent should apply to drugs 
    marketed by prescription in a foreign country but not marketed in the 
    United States. Some drugs that are marketed by prescription in a 
    foreign country were considered for approval in the United States but 
    not approved because FDA believed that their safety and efficacy had 
    not been proven. Furthermore, the agency believes that it is not 
    appropriate for a drug that has characteristics that have been 
    determined to require a prescription in a foreign country to enter 
    directly into the OTC market in the United States when the U.S. 
    population has no experience with the drug either on a prescription or 
    OTC basis. The agency considers it essential that any prescription drug 
    have some U.S. marketing experience before its OTC marketing is 
    permitted in this country. Further, the agency believes that the 
    criteria being considered in this document should not be applicable to 
    establish use to a material time and to a material extent if the drug 
    has no direct-to-consumer OTC marketing experience in any country.
        OTC drugs whose marketing history shows that they were marketed in 
    the United States without appropriate authorization would not be 
    eligible for consideration in the OTC drug review based on the new 
    material time and extent eligibility criteria. To treat such drugs 
    otherwise would reward those who chose not to comply with the law.
        These criteria would not apply to sustained-release products, which 
    remain new drugs under 21 CFR 200.31 because of the difficulties 
    associated with developing a standardized monograph that would cover 
    the wide variety of sustained release formulations. These products 
    almost always involve complex bioavailability/bioequivalence questions.
        The agency recognizes that some of the countries listed in 
    802(b)(1)(A) of the act (e.g., Australia, Canada, New Zealand, and the 
    United Kingdom) have a third class of OTC drug products that can be 
    sold only by a pharmacist. When consumers purchase OTC drugs in this 
    class, there is intervention by a health professional and an 
    opportunity for professional consultation. The agency would not 
    consider this type of OTC marketing to be similar to the broad OTC 
    marketing in the United States, where products are marketed in many 
    various outlets, often with no opportunity for professional 
    consultation. The agency seeks specific comment on whether marketing in 
    a foreign country as a third class of drugs sold by a pharmacist should 
    be considered when evaluating whether a drug has been marketed for a 
    material time and to a material extent.
    
    B. Time Used (Material Time)
    
        The agency is considering proposing that this OTC marketing be for 
    a minimum of 5 years to satisfy the material time requirements of the 
    act. In determining how many years should constitute marketing for a 
    material time, the agency's principal concern is that the condition be 
    marketed for a sufficient time to detect serious and/or important 
    adverse events. The agency believes that a minimum 5-year timeframe 
    should be required to provide an appropriate margin of safety to ensure 
    that adverse event reporting is sufficient to detect almost all types 
    of serious and/or important adverse events if sufficient volume of 
    sales and postmarketing surveillance in this timeframe can be 
    documented (see section II. C. of this document).
        If the condition has not been marketed previously in the United 
    States, the agency believes that the specific condition should be 
    marketed for this 5-year minimum time period in a population 
    demonstrated to be representative of the U.S. population (e.g., by 
    race, gender, ethnicity, and other pertinent factors) that would be 
    exposed to the OTC drug if it were marketed in the United States under 
    an OTC drug monograph. Foreign marketing exposure (i.e., diversity 
    within the user population) would have to be described sufficiently to 
    ensure that the condition can be reasonably extrapolated to the U.S. 
    population. Any cultural or geographic differences in the way drugs are 
    used in the foreign country and in the United States would
    
    [[Page 51630]]
    
    be required to be explained. The agency seeks specific comment on how 
    the representation of the population could be established.
    
    C. Extent of Distribution (Material Extent)
    
        The agency believes that there should be some flexibility when 
    assessing the extent of marketing for an OTC drug product condition. 
    Because the agency intends to consider numerous factors in determining 
    whether the condition has been marketed to a material extent, the 
    agency does not believe that this determination should be based solely 
    on the sale of a certain established number of dosage units, as one 
    petition suggested. The agency also believes that the extent of the 
    condition's use should be sufficient to detect serious and/or important 
    adverse events, including rare events, to demonstrate a favorable 
    adverse event profile. The agency is considering using the following 
    factors to evaluate whether the extent of use of a condition is 
    sufficient to detect serious and/or important adverse events: (1) 
    Number of dosage units sold; (2) number and types of adverse event 
    reports, and the requirements of the reporting system; (3) risks and 
    consequences associated with the therapeutic category and indication; 
    (4) use pattern (frequency: Occasional, acute, chronic); (5) potential 
    toxicity (including dosage form and route of administration); and (6) 
    history of use (i.e., use indications and exposures, including their 
    toxicities)
    
    III. Implementation
    
    A. Two-Step Application Process
    
        The agency is considering proposing that sponsors first demonstrate 
    that a condition meets the basic eligibility requirements of marketing 
    to a material extent and for a material time, in the appropriate 
    format, before the agency accepts any data in support of the 
    condition's general recognition of safety and effectiveness. Upon 
    evaluation of the eligibility data, the agency would notify the sponsor 
    of its determination. If the condition were found to be eligible, the 
    sponsor could then submit its data to demonstrate safety and 
    effectiveness in accordance with part 330.
        The agency believes that sponsors should not incur unnecessary 
    costs for developing safety and effectiveness data for a condition of 
    use that may not meet the basic eligibility requirements of marketing 
    to a material extent and for a material time. In addition, the agency 
    does not want to expend scarce resources evaluating safety and 
    effectiveness data for a condition if it does not meet the basic 
    eligibility criteria.
        The agency notes that the advisory review panels mentioned in 
    Sec. 330.10(a)(1) no longer exist. Therefore, safety and effectiveness 
    data would be reviewed on an individual basis, with the assistance of 
    the agency's current Nonprescription Drugs Advisory Committee and other 
    Drug Advisory Committees when deemed appropriate. If the agency 
    determined that the data were sufficient to establish that the 
    condition was generally recognized as safe and effective, it would then 
    propose in the Federal Register to include the condition in an 
    appropriate OTC drug monograph.
    
    B. Compendial Monograph
    
        FDA believes there is a need for publicly available chemical 
    standards to ensure that all OTC drug products contain ingredients that 
    are chemically equivalent to those described in an OTC monograph. To 
    ensure that OTC drugs remain safe and effective for their intended 
    uses, the agency believes that any ingredient included in an OTC drug 
    monograph should also be recognized in an official compendium (e.g., 
    the U.S. Pharmacopeia) setting forth its standards of identity, 
    strength, quality, and purity. On this basis, the agency is considering 
    proposing that no final monograph be issued and no interim marketing be 
    allowed until there is an official compendial monograph that is 
    consistent with the marketed ingredients used to establish general 
    recognition of safety and effectiveness.
    
    C. Marketing Policy
    
        All new drugs and drugs marketed under an OTC monograph must be 
    demonstrated to be safe and effective before they may be marketed in 
    the United States. Although conditions evaluated under the OTC drug 
    review were permitted to remain on the market during the review process 
    in view of their long history of use in this country, the agency 
    believes that allowing the marketing of a new condition before the 
    agency has evaluated its safety and effectiveness would subject the 
    public to unnecessary risk. Therefore, the agency is considering 
    permitting a new condition to be marketed only after the Commissioner 
    tentatively determines that the condition is generally recognized as 
    safe and effective and publishes this conclusion in the Federal 
    Register as a proposal for comment. Marketing could only occur after 
    the comments are reviewed and an appropriate notice allowing such 
    marketing is published in the Federal Register or after inclusion of 
    the condition in the appropriate OTC drug final monograph.
        Any interim marketing that might be allowed, pending issuance of a 
    final rule, would be subject to the risk that the Commissioner could 
    adopt a different position in the final rule that would require 
    relabeling, recall, or other regulatory action. The agency seeks 
    specific comment on this marketing policy.
    
    IV. Analysis of Impacts
    
        The agency also seeks specific comment regarding any substantial or 
    significant economic benefit or impact that this rulemaking would have 
    on manufacturers or consumers of OTC drug products. Comments regarding 
    the benefit or impact of this rulemaking on such manufacturers or 
    consumers should be accompanied by appropriate documentation. The 
    agency will evaluate any comments and supporting data that are received 
    and will assess the economic impact of this rulemaking in the preamble 
    to the proposed rule.
