Pharmacology & Mechanism of Action
Chlorpheniramine Maleate is an alkylamine antihistamine. It is one of the most potent histamine H1-receptor blocking agents which is used as a potent antihistamine. This generally causes less sedation than promethazine. Chlorpheniramine Maleate exerts its effects by blocking H1-receptor competitively.
