Description

Methoxyphenamine also known as 2-methoxy-N-methylamphetamine (OMMA), is a beta adrenergic receptor agonist nd is used as a bronchodilator to treat asthma, chronic obstructive pulmonary disease (COPD) and postinfectious cough. In addition, methoxyphenamine using is prohibited in sports according to the regulations of the World Anti-Doping Agency (WADA).

It was revealed, that methoxyphenamine antagonizes the effects of histamine both in vivo and in vitro. In vitro studies indicate a noncompetitive antagonism. Histamine-induced contractions of the isolated guinea-pig ileum were antagonized by methoxyphenamine (10(-5) to 10(-3) M). The histamine log-concentration-response curve was shifted to the right in a parallel manner by methoxyphenamine (10(-5) to 10(-4) M), without depression of maximum responses. However, at higher concentrations, maximum responses were reduced. The slope of the Schild plot was significantly different from -1. The degree of the rightward shift of the concentration-response curves to histamine, produced by 10(-5) M of methoxyphenamine [3.90-(2.83, 4.97) fold], was not significantly different from that produced by 3 x 10(-9) M of mepyramine [4.60-(2.86, 6.52) fold]. Methoxyphenamine, at concentrations of 10(-5) to 3 x 10(-4) M, had no significant effect on responses of guinea-pig ilea to acetylcholine (10(-9) to 10(-5) M).
