Key differences
Norvasc belongs to Cardiovascular Medications while Lumigan belongs to Eye Care and Ophthalmic Treatments. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Norvasc: Amlodipine selectively blocks L-type calcium channels in vascular smooth muscle, reducing transmembrane calcium influx and producing peripheral arterial vasodilation. Lumigan: Bimatoprost is a prostamide analogue that increases aqueous humour outflow through both the trabecular meshwork and the uveoscleral pathway, lowering intraocular pressure.
When Norvasc is preferred
Norvasc is approved in adults for the treatment of essential hypertension and chronic stable angina, and for vasospastic (Prinzmetal's) angina.
When Lumigan is preferred
Lumigan is approved in adults for the reduction of elevated intraocular pressure in patients with chronic open-angle glaucoma or ocular hypertension.
