Overview
Amlodipine is a calcium channel blocker used in veterinary medicine primarily to manage hypertension (high blood pressure) in dogs and cats. It helps in dilating blood vessels, thereby reducing the workload on the heart.
How It Works
Amlodipine works by inhibiting the influx of calcium ions into vascular smooth muscle and cardiac muscle. This action relaxes the blood vessels, lowering blood pressure and allowing the heart to pump more efficiently.
Uses & Indications
Amlodipine is indicated for managing systemic hypertension in pets, particularly cats. It is also used for controlling certain heart conditions that result from high blood pressure.
