Therapeutic potential of reserpine in metabolic syndrome: An evidence based study.

Reserpine is as old as the scientific diagnosis of hypertension. For many years' clinicians have used it for the treatment of high blood pressure, but with the passage of time and introduction of new anti-hypertensive drugs, the usage of reserpine has gone down drastically most probably due to poorly understood mechanism of action and multiple misleading adverse effects precisely due to high dosing of reserpine. With an aim to elucidate the specific mechanism of action, we screened reserpine against various targets associated with regulation of blood pressure.
