[Oral drugs containing alcohol: Should we be careful?]

Abstract

Ethanol is an excipient with known effect whose presence is regulated because it can cause adverse effects, notably a misuse. In order to raise awareness of this risk, this study searched all oral drugs with ethanol as an excipient from the Theriaque® database. All drugs marketed in France with a unit dose ethanol intake of 0.1g or more were identified and analyzed, according to the maximum unit and daily dosage recommended by the manufacturer. This research revealed 106 pharmaceutical specialties responsible for a unit intake of ethanol of 0.1g or more among the 8532 oral drugs containing ethanol (1.2 %): 2 at a daily dose >13g and the majority (57/106; 54 %) at a daily dose <1g. These are mainly oral solutions (97/106; 91 %) of phytotherapy (45/97; 46 %). The most frequently found therapeutic class was antitussive (12/106; 11 %). The majority of drugs are over-the-counter medication (56/106; 53 %). Overall, 106 drugs on the French market can be associated with a risk of misuse and cause adverse effects in vulnerable populations such as children and pregnant women. Vigilance and appropriate monitoring is required for these drugs (especially those over-the-counter ones), and their substitution should be preferred if possible.
