mecamylamine oral Uses
Mecamylamine is used to treat moderately severe to severe high blood pressure. It can also be used in sudden high blood pressure emergencies (malignant hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Mecamylamine belongs to a class of drugs known as ganglion blockers. It works by relaxing blood vessels so blood can flow more easily.How to use mecamylamine oral
