Definition

ChEBI: Amezinium metilsulfate is an azaheterocycle sulfate salt of amezinium. It is a sympathomimetic drug which suppresses noradrenaline reuptake and thereby elevating blood pressure. It is used for the treatment of low blood pressure in patients undergoing dialysis. It has a role as an EC 1.4.3.4 (monoamine oxidase) inhibitor, an antihypotensive agent, a sympathomimetic agent and an adrenergic uptake inhibitor. It contains an amezinium.

Manufacturing Process

18.7 parts of 1-phenyl-4-aminopyridazone-(6) and 19 parts of dimethyl sulfate in 400 parts of xylene are kept at 120°C for one hour while mixing well. The reaction mixture is suction filtered, 28 parts (89.5% of the theory) of 1-phenyl-4-amino-6-methoxypyridazinium methosulfate is obtained having a melting point of 173°C to 174°C after recrystallization from acetonitrile. The perchlorate has a melting point of 179°C to 182°C.

Therapeutic Function

Antihypotensive
