Cremagel contains Diltiazem, a calcium-channel blocker that Australian doctors commonly prescribe to treat high blood pressure, angina, and cardiac arrhythmias. Cremagel relaxes blood vessels and reduces heart workload. It also improves blood flow.
What is Cremagel (Diltiazem)?
Cremagel is formulated with Diltiazem, which prevents calcium from reaching cardiac cells and smooth muscles. It relaxes the arterial walls and reduces the heartbeat by blocking calcium channels. This drug is prescribed to control hypertension symptoms, regulate angina, and regulate irregular rhythms like atrial fibrillation.
Key Features
- Active Ingredient: Diltiazem Hydrochloride
- Formulation: Tablets or capsules with extended-release (specific formulations can vary).
- Primary Uses: Hypertension, angina pectoris, supraventricular arrhythmias
- Prescription: Required in Australia
How Does Cremagel Work?
Diltiazem blocks L-type Calcium Channels in the Heart and Vascular Smooth Muscle. The action of Diltiazem dilates peripheral and coronary blood vessels, reducing oxygen consumption in the heart. It also stabilises rhythm. This lowers the blood pressure and relieves pain in the chest caused by decreased blood flow.
When Should You Use Cremagel?
- Reduce cardiovascular risks by managing hypertension.
- Improve coronary blood circulation to treat and prevent angina pectoris.
- To control supraventricular tachycardia and atrial fibrillation/flutter.
- Beta-blockers should be avoided or tolerated.
