Effects of alpha-methylnoradrenaline and alpha-methyldopamine in reserpine-induced ulcers in rats

alpha-Methyldopamine and alpha-methylnoradrenaline administered intraperitoneally afforded significant protection in reserpine-induced ulcers in rats. The optimal doses were 2 and 4 mg/kg. Lower and higher doses were less effective. alpha-Methyldopamine and alpha-methyl-noradrenaline probably act by reestablishing the normal adrenergic tone which is diminished in reserpine-induced ulcers.
