Abstract

Oral tablets are designed to be taken with water; however, often they are ingested with alcoholic beverages. In this study, it was analyzed on in vitro drug release of three over-the-counter oral dosage forms: immediate-release acetylsalicylic acid (ASA), immediate-release metformin hydrochloride (Met-HCl) and extended-release sodium diclofenac (DCL-Na) co-administered with beer, tequila and wine. It was compared the effect of these alcoholic beverages and ethanol on drug-releasing profiles too. Appropriate dissolution media (Pharmacopeia) for ASA and Met-HCl (500 mg) and sodium diclofenac (Na-DCL) (100 mg) were supplemented with beer, tequila, or white wine, at a proportion of 13 g of pure ethanol. Furthermore, the results were compared with the FDA proposed method (40% ethanol). It was shown release ASA tablets were significantly different (P
