Methoxyphenamine (o-methoxy-N,alpha-dimethylphenethylamine, Orthoxine) used in earlier times as a bronchodilator is prohibited in sports according to the regulations of the World Anti-Doping Agency (WADA). The drug and several of its metabolites are commonly analysed in doping control screening assays using

1. Nasal resistance in anaesthetized rats was assessed by measuring air overflow during ventilation of the nasal passages at constant pressure. Nasal basal resistance was reduced in a dose-dependent manner by methoxyphenamine hydrochloride (0.01-30 mg kg-1, i.v.), pseudoephedrine hydrochloride (0.03-3

(i) The urinary elimination of methoxyphenamine (MPA) and its metabolites in underivatized samples was examined after single and multiple oral administration to pregnant and non-pregnant mice by GLC and GLC-MS. (ii) The major metabolite O-desmethylmethoxyphenamine (ODMP), along with lesser amounts
