[N-Alkyl-2-(5-methyl-4-imidazolyl)ethylamines. Synthesis and effect on gastric secretion].

Synthesis of some 5-methylhistamines alkylated on the amino group (form. I) together with a new method (C) of obtaining them via 5-methylhistaminol, are described. Both the agonistic and antagonistic pharmacological activities of these methylhistamines were studied in vivo on gastric secretion of different animal species (conscious dogs and cats and anaesthetized rats).
