General description of Calan (verapamil)
Calan, also known as verapamil, is a medication commonly prescribed to treat high blood pressure, chest pain caused by angina, and certain heart rhythm disorders. It belongs to a class of drugs called calcium channel blockers, which work by relaxing and widening the blood vessels, allowing for smoother blood flow and reduced strain on the heart.
This medication comes in various forms, including tablets, extended-release tablets, and injections. The dosage and frequency of administration will depend on the individual’s condition and the doctor’s recommendation.
Mechanism of Action
Calan works by inhibiting the influx of calcium into cells, especially in the smooth muscle cells of the heart and blood vessels. By reducing the concentration of calcium, Calan relaxes the arterial smooth muscle, resulting in vasodilation and decreased peripheral resistance. This helps to lower blood pressure and improve oxygen delivery to the heart muscle.
Indications
Calan is primarily used for the treatment of hypertension (high blood pressure). It can be used alone or in combination with other antihypertensive agents. In addition, Calan is prescribed to relieve chest pain caused by angina and to manage certain heart rhythm disorders such as atrial fibrillation and paroxysmal supraventricular tachycardia.
Contraindications
There are certain conditions in which Calan should not be taken. These include:
– Hypersensitivity to verapamil or any other ingredients in the medication
– Severe hypotension (low blood pressure)
– Sick sinus syndrome (disorder of the heart’s electrical system)
– Second- or third-degree atrioventricular block (abnormal heart rhythm)
– Left ventricular dysfunction (poor heart function)
– Use of beta-blockers in patients with ischemic heart disease
– Concurrent use of intravenous beta-blockers
– Patients with a history of cardiogenic shock or heart failure
It is important to consult with a healthcare professional before starting Calan to ensure safety and effectiveness.
