Introduction to Calan SR
Calan SR is a medication primarily used for the treatment of high blood pressure, angina (chest pain), and certain heart rhythm disorders. It contains the active ingredient verapamil hydrochloride, which belongs to the class of drugs known as calcium channel blockers.
What is Calan SR?
Calan SR is the brand name for the generic drug verapamil hydrochloride. It works by relaxing and widening the blood vessels, allowing the heart to pump blood more easily and effectively. This helps in reducing high blood pressure and improving blood flow to the heart.
Uses of Calan SR
Calan SR has multiple therapeutic uses, including:
- Treatment of high blood pressure (hypertension): Calan SR helps to lower blood pressure levels, preventing potential complications such as heart attacks and strokes.
- Management of angina: This medication can relieve the chest pain associated with angina by relaxing and widening the coronary arteries, which supply blood to the heart muscle.
- Control of certain heart rhythm disorders: Calan SR may be prescribed to regulate irregular heart rhythms, such as atrial fibrillation or atrial flutter.
How does it work?
Calan SR works by blocking calcium channels in the cells of the heart and blood vessels. By doing so, it inhibits the entry of calcium ions, which are necessary for muscle contraction. This action results in relaxation of the muscle cells in the walls of blood vessels and the heart, leading to improved blood flow and decreased workload on the heart.
“According to the American Heart Association, calcium channel blockers like Calan SR are effective in reducing blood pressure and preventing heart-related complications in patients with hypertension and coronary artery disease.”

2. Medical Uses of Calan SR (verapamil hydrochloride)
Calan SR, also known by its generic name verapamil hydrochloride, is a medication primarily used to treat high blood pressure and certain heart conditions. It belongs to a class of drugs called calcium channel blockers, which work by relaxing the blood vessels and reducing the workload on the heart.
2.1 High Blood Pressure (Hypertension)
Calan SR is commonly prescribed for the treatment of hypertension, a condition characterized by persistently high blood pressure levels. By blocking calcium channels in the walls of blood vessels, verapamil helps dilate the arteries and lower blood pressure.
Studies have shown that Calan SR effectively reduces blood pressure in patients with both mild and severe hypertension. It can be used as a standalone therapy or in combination with other antihypertensive medications.
According to the American Heart Association, controlling high blood pressure is essential for reducing the risk of heart attack, stroke, and other cardiovascular diseases.
2.2 Angina
Another common use of Calan SR is in the treatment of angina, a condition characterized by chest pain or discomfort due to inadequate blood flow to the heart muscle. Verapamil helps relax and expand the coronary arteries, which supply oxygen-rich blood to the heart.
A study published in the Journal of the American College of Cardiology demonstrated that verapamil significantly improves exercise tolerance and reduces the frequency and severity of angina attacks. It is often prescribed to individuals with chronic stable angina or variant angina (Prinzmetal’s angina).
2.3 Arrhythmias
Verapamil hydrochloride is also effective in managing certain arrhythmias (abnormal heart rhythms). By inhibiting the calcium influx into cardiac muscle cells, it slows down the electrical signals in the heart, helping to restore a normal heart rhythm.
Calan SR is commonly used to treat supraventricular arrhythmias, including atrial fibrillation and atrial flutter. It can also be beneficial in controlling ventricular arrhythmias, such as ventricular tachycardia.
According to the American Heart Association, maintaining a regular heart rhythm is crucial for overall heart health and preventing complications.
