Abstract:
Neocodion, a codeine antitussive preparation (codeine camphosulfonate + Grindelia + sulfogaiacol) is known to be misused by opiate addicts. This study aimed to examine the evolution in Neocodion use between 1992 and 2002. Since 1992, three surveys (1992, 1997 and 2002) investigating Neocodion misuse were performed via several community networks of pharmacists. During the same time, data on Neocodion use were extracted from the French drug-dependence monitoring programme (OPPIDUM [Observation des Produits Psychotropes Illicites ou Détournés de leur Utilisation Médicamenteuse]). A marked and continuous decrease in Neocodion consumption was observed. The number of requests for Neocodion per pharmacy and per week largely decreased from 9.9 to 2.1 between 1992 and 2002. OPPIDUM data also showed a reduction in the rate of Neocodion consumption (from 8% in 1992 to 0.4% in 2002). Patients were older (30.4 years in 1992 and 33.7 years in 2002) and their socioeconomic conditions were better. Eighty-six percent of the subjects studied were poly-drug consumers. In fact, Neocodion was less sought after for opiate maintenance than for its psychoactive effects. Despite the reduction in the consumption of Neocodion, the changes observed in the consumption patterns for this medication suggest that vigilance is still required.
