Piclonidine is imidazoline derivative. Piclonidine has a relative specificity for the hypotensive action and thus indicate that the compound differs from the chemical congener clonidine which has other pharmacological effects involving several peripheral or centrally regulated autonomic functions. Unlike clonidine, this chemically related compound did not evoke hypertensive episodes or cause sedation in animals up to the oral dose of 1 mg/kg.
