Schedules of Controlled Substances: Table of Excluded Nonnarcotic Products: Vicks® VapoInhaler®.

This final rule adopts the interim final rule, with a correction to spelling of the manufacturer's name that was published in the Federal Register on October 27, 2015. The Drug Enforcement Administration is amending the table of Excluded Nonnarcotic Products to update the listing for Vicks® VapoInhaler®, containing 50 mg levmetamfetamine in a nasal decongestant inhaler, marketed by The Procter & Gamble Company. This over-the-counter, non-narcotic drug product is excluded from provisions of the Controlled Substances Act.

Schedules of Controlled Substances: Table of Excluded Nonnarcotic Products: Nasal Decongestant Inhaler/Vapor Inhaler. Final rule.

This final rule adopts, without change, the interim final rule that was published in the Federal Register on October 27, 2015. The Drug Enforcement Administration is amending the table of Excluded Nonnarcotic Products to update the company name for the drug product Nasal Decongestant Inhaler/Vapor Inhaler (containing 50 milligrams levmetamfetamine) to Aphena Pharma Solutions--New York, LLC. This over-the-counter, nonnarcotic drug product is excluded from the provisions of the Controlled Substances Act.

Schedules of controlled substances; table of excluded nonnarcotic products: nasal decongestant inhalers manufactured by Classic Pharmaceuticals, LLC. Final rule.

Under this Final Rule, the Drug Enforcement Administration (DEA) is updating the Table of Excluded Nonnarcotic Products found in 21 CFR 1308.22 to include the Nasal Decongestant Inhaler/Vapor Inhaler (containing 50 mg Levmetamfetamine) manufactured by Classic Pharmaceuticals, LLC and marketed under various private labels (to include the "Premier Value" and "Kroger" labels). This nonnarcotic drug product, which may be lawfully sold over the counter without a prescription under the Federal Food, Drug, and Cosmetic Act, is excluded from provisions of the Controlled Substances Act (CSA) pursuant to 21 U.S.C. 811(g)(1).

Cold, cough, allergy, bronchodilator, and antiasthmatic drug products for over-the-counter human use; amendment of monograph for OTC nasal decongestant drug products. Final rule.

The Food and Drug Administration (FDA) is issuing a final rule to amend the final monograph (FM) for over-the-counter (OTC) nasal decongestant drug products (drug products used to relieve nasal congestion due to a cold, hay fever, or other upper respiratory allergies) to add phenylephrine bitartrate (PEB), both individually and in combination drug products in an effervescent dosage form, as generally recognized as safe and effective (GRASE). An effervescent dosage form is intended to be dissolved in water before taking by mouth. This final rule is part of FDA's ongoing review of OTC drug products.

Cold, cough, allergy, bronchodilator, and antiasthmatic drug products for over-the-counter human use; final monograph for combination drug products. Final rule.

The Food and Drug Administration (FDA) is issuing a final rule in the form of a final monograph that establishes conditions under which over-the-counter (OTC) cold, cough, allergy, bronchodilator, and antiasthmatic (cough-cold) combination drug products are generally recognized as safe and effective and not misbranded as part of its ongoing review of OTC drug products. FDA is issuing this final rule after considering public comments on the agency's proposed regulation (tentative final monograph) and new data and information on OTC cough- cold combination drug products that have come to the agency's attention.

Regional-dependent intestinal permeability and BCS classification: elucidation of pH-related complexity in rats using pseudoephedrine.

Based on its lower Log P value relative to metoprolol, a marker for the low/high-permeability (P(eff)) class boundary, pseudoephedrine was provisionally classified as BCS low-permeability compound. On the other hand, following oral administration, pseudoephedrine fraction dose absorbed (F(abs)) and systemic bioavailability approaches 100%. This represents a challenge to the generally recognized P(eff)-F(abs) correlation. The purpose of this study was to elucidate the underlying mechanisms behind the confusion in pseudoephedrine's BCS classification. Pseudoephedrine's BCS solubility class was determined, and its physicochemical properties and intestinal permeability were thoroughly investigated, both in vitro and in vivo in rats, considering the complexity of the whole of the small intestine. Pseudoephedrine was found to be unequivocally a high-solubility compound. All of the permeability studies revealed similar phenomenon; at any given intestinal segment/pH, the permeability of metoprolol was higher than that of pseudoephedrine, however, as the intestinal region becomes progressively distal, and the pH gradually increases, pseudoephedrine's permeability rises above that of metoprolol in the former segment. This unique permeability pattern likely explains pseudoephedrine's complete absorption. In conclusion, pseudoephedrine is a BCS Class I compound; no discrepancy between P(eff) and F(abs) is involved in its absorption. Rather, it reflects the complexity behind P(eff) when considering the whole of the intestine. We propose to allow high-permeability classification to drugs with P(eff) that matches/exceeds the low/high class benchmark anywhere throughout the intestinal tract and not restricted necessarily to the jejunum.
