The Food and Drug Administration (FDA, we, our) is issuing a final regulation declaring dietary supplements containing ephedrine alkaloids adulterated under the Federal Food, Drug, and Cosmetic Act (the act) because they present an unreasonable risk of illness or injury under the conditions of use recommended or suggested in labeling, or if no conditions of use are suggested or recommended in labeling, under ordinary conditions of use. We are taking this action based upon the well-known pharmacology of ephedrine alkaloids, the peer-reviewed scientific literature on the effects of ephedrine alkaloids, and the adverse events reported to have occurred in individuals following consumption of dietary supplements containing ephedrine alkaloids.  相似文献

On October 17, 2001, DEA published a Final Rulemaking (66 FR 52670) in which DEA added red phosphorus, white phosphorus (also known as yellow phosphorus) and hypophosphorous acid (and its salts) as List I chemicals. This action was taken because of the use and importance of these chemicals in the illicit manufacture of methamphetamine (a Schedule II controlled substance). As List I chemicals, handlers of these materials became subject to Controlled Substances Act (CSA) chemical regulatory controls including registration, recordkeeping, reporting, and import/export requirements. DEA had determined that these controls are necessary to prevent the diversion of these chemicals to clandestine drug laboratories. In order to provide flexibility for legitimate businesses, the October 17, 2001 rule established, on an interim basis, specific exclusions and waivers for chemical handlers engaged in certain activities. DEA has completed its review of comments pertaining to these interim provisions. This rulemaking finalizes these exclusions and waivers related to the handling of the listed chemicals red phosphorus, white phosphorus, and hypophosphorous acid (and its salts).  相似文献

The Food and Drug Administration (FDA) is amending its patent submission and listing requirements for new drug applications (NDAs). The final rule clarifies the types of patents that must and must not be submitted and revises the declaration that NDA applicants must provide regarding their patents to help ensure that NDA applicants submit only appropriate patents. The final rule also revises the regulations regarding the effective date of approval for certain abbreviated new drug applications (ANDAs) and certain other new drug applications, known as 505(b)(2) applications, submitted under the Federal Food, Drug, and Cosmetic Act (the act). In certain situations, Federal law bars FDA from making the approval of certain ANDA and 505(b)(2) applications effective for 30 months if the applicant has certified that the patent claiming a drug is invalid or will not be infringed, and the patent owner or NDA holder then brings suit for patent infringement. The final rule also states that there is only one opportunity for a 30-month stay in the approval date of each ANDA and 505(b)(2) application. The final rule will make the patent submission and listing process more efficient as well as enhance the ANDA and 505(b)(2) application approval processes.  相似文献

The Food and Drug Administration (FDA) is amending the regulation that established conditions under which over-the-counter (OTC) skin protectant astringent drug products are generally recognized as safe and effective and not misbranded. This action revises some labeling for astringent drug products to be consistent with the final rule for OTC skin protectant drug products (68 FR 33362, June 4, 2003) and adds labeling for certain small packages (styptic pencils). This action is part of FDA's ongoing review of OTC drug products. Elsewhere in this issue of the Federal Register, FDA is publishing a companion proposed rule, under FDA's usual procedure for notice-and-comment rulemaking, to provide a procedural framework to finalize the rule in the event the agency receives any significant adverse comments and withdraws this direct final rule.  相似文献

The Food and Drug Administration (FDA) is announcing that it has reclassified two fixed-bearing knee joint prostheses, the knee joint patellofemorotibial metal/polymer porous-coated uncemented prosthesis, which is intended to be implanted to replace a knee joint, and the knee joint femorotibial (uni-compartmental) metal/polymer porous-coated uncemented prosthesis, which is intended to be implanted to replace part of a knee joint. FDA has reclassified the devices from class III (premarket approval) into class II (special controls). The special control that will apply is a guidance document entitled "Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses; Guidance for Industry and FDA." The agency is reclassifying these devices into class II because special controls, in addition to general controls, will provide reasonable assurance of the safety and effectiveness of the devices, and there is sufficient information to establish special controls. The agency is also announcing that it has issued an order in the form of a letter to the Orthopedic Surgical Manufacturers Association (OSMA) reclassifying the devices.  相似文献

The Food and Drug Administration (FDA) is amending its bottled water quality standard regulations by establishing an allowable level for the contaminant uranium. As a consequence, bottled water manufacturers are required to monitor their finished bottled water products for uranium at least once each year under the current good manufacturing practice (CGMP) regulations for bottled water. Bottled water manufacturers are also required to monitor their source water for uranium as often as necessary, but at least once every 4 years unless they meet the criteria for the source water monitoring exemptions under the CGMP regulations. FDA will retain the existing allowable levels for combined radium-226/-228, gross alpha particle radioactivity, and beta particle and photon radioactivity. This direct final rule will ensure that the minimum quality of bottled water, as affected by uranium, combined radium-226/-228, gross alpha particle radioactivity, and beta particle and photon radioactivity, remains comparable with the quality of public drinking water that meets the Environmental Protection Agency's (EPA's) standards. FDA is issuing a direct final rule for this action because the agency expects that there will be no significant adverse comment on this rule. Elsewhere in this issue of the Federal Register, FDA is publishing a companion proposed, rule under the agency's usual procedure for notice-and-comment rulemaking, to provide a procedural framework to finalize the rule in the event the agency receives any significant adverse comments and withdraws this direct final rule. The companion proposed rule and direct final rule are substantively identical.  相似文献

The Food and Drug Administration (FDA) is amending its regulations to require that the labeling for all systemic antibacterial drug products (i.e., antibiotics and their synthetic counterparts) intended for human use include certain statements about using antibiotics in a way that will reduce the development of drug-resistant bacterial strains. The final rule reflects a growing concern in FDA and the medical community that unnecessary use of systemic antibacterials has contributed to a dramatic increase in recent years in the prevalence of drug-resistant bacterial infections. The final rule is intended to encourage physicians to prescribe systemic antibacterial drugs only when clinically necessary. The final rule is also intended to encourage physicians to counsel their patients about the proper use of such drugs and the importance of taking them exactly as directed.  相似文献

The Food and Drug Administration (FDA) is announcing the availability of a revised guidance entitled "Q3B(R) Impurities in New Drug Products.' The revised guidance, which updates a guidance on the same topic published in the Federal Register of May 19, 1997 (the 1997 guidance), was prepared under the auspices of the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). The revised guidance is intended to provide guidance to applicants for drug marketing registration on the content and qualification of impurities in new drug products produced by chemically synthesized new drug substances not previously registered in a country, region, or member State. The revised guidance clarifies the 1997 guidance, adds information, and provides consistency with more recently published ICH guidances. The revised guidance complements the ICH guidance entitled "Q3A(R) Impurities in New Drug Substances.'  相似文献

The Food and Drug Administration (FDA) is reclassifying arrhythmia detector and alarm devices from class III to class II (special controls). This device is used to monitor an electrocardiogram (ECG) and to produce a visible or audible signal or alarm when an atrial or ventricular arrhythmia occurs. An atrial or ventricular arrhythmia occurs during a premature contraction or ventricular fibrillation. FDA is reclassifying this device based on new information contained in reclassification petitions regarding the device submitted by the Health Industry Manufacturers Association (HIMA) (now known as Advamed), Quinton Instrument Co., and Zymed Medical Instrumentation. Elsewhere in this issue of the Federal Register, FDA is announcing the availability of the guidance document that will serve as the special control for this device. FDA is taking this action under the Federal Food, Drug, and Cosmetic Act (the act), as amended by the Medical Device Amendments of 1976 (the 1976 amendments), the Safe Medical Devices Act of 1990 (the SMDA), the Food and Drug Administration Modernization Act of 1997 (the FDAMA), and the Medical Device User Fee and Modernization Act of 2002 (MDUFMA).  相似文献
