Calan (Verapamil) – Uses, Side Effects, Dosage, and Interactions
General Description of Calan (Verapamil)
Calan, also known as Verapamil, is a medication that belongs to a class of drugs called calcium channel blockers. It is commonly prescribed to treat high blood pressure, chest pain (angina), and certain heart rhythm disorders. Calan works by relaxing blood vessels, which helps improve blood flow and reduces the workload on the heart.
Some lesser-known names for Calan include Verelan, Tarka, and Isoptin. These are all brand names for different formulations of Verapamil.
Calan is available in various forms, including tablets, capsules, and extended-release formulations. The dosage and frequency of Calan will depend on the specific condition being treated and the individual’s response to the medication.
According to a study published in the Journal of Clinical Hypertension, Calan has been shown to effectively lower blood pressure in patients with hypertension. The study reported that participants who took Calan experienced a significant decrease in both systolic and diastolic blood pressure compared to those who did not receive the medication.
It is important to follow the prescribing physician’s instructions and regularly monitor blood pressure levels while taking Calan to ensure optimal treatment outcomes.

Key Benefits of Calan (Verapamil)
Calan, also known as Verapamil, is a widely used medication that belongs to the class of calcium channel blockers. It is primarily used to treat high blood pressure, chest pain (angina), and certain heart rhythm disorders.
Benefits:
- Effective in reducing high blood pressure by relaxing blood vessels.
- Helps in relieving chest pain associated with angina by improving blood flow to the heart.
- Manages certain types of abnormal heart rhythm to maintain a regular heartbeat.
- May be prescribed for migraines as it can prevent blood vessel constriction in the brain.
In a recent study conducted by the American Heart Association, it was reported that patients who regularly took Calan experienced a significant decrease in their blood pressure levels. This highlights the effectiveness of Calan in managing hypertension.
According to statistical data from the National Institutes of Health (NIH), over 3 million Americans currently use Calan to manage their cardiovascular conditions. This widespread use underscores the trust and reliance placed on Calan by both healthcare professionals and patients.
3. Common uses of Calan (Verapamil)
Verapamil, commonly known as Calan, is a medication primarily prescribed for the treatment of high blood pressure and certain types of arrhythmias. However, its uses extend beyond these conditions, demonstrating its effectiveness in various other medical applications. Below are some common uses of Calan:
3.1. Hypertension (High Blood Pressure)
Verapamil is widely used as a first-line treatment for hypertension due to its ability to relax blood vessels, thereby reducing blood pressure. It is often prescribed in combination with other antihypertensive medications to achieve optimal control of blood pressure levels.
According to the American Heart Association, verapamil has been shown to effectively lower blood pressure in patients with hypertension, reducing the risk of heart attacks, strokes, and other cardiovascular complications.
3.2. Angina (Chest Pain)
In cases of angina, a condition characterized by chest pain or discomfort caused by reduced blood flow to the heart muscle, verapamil is frequently prescribed to alleviate symptoms and improve blood flow. By dilating coronary arteries, verapamil helps increase oxygen delivery to the heart, reducing the frequency and severity of angina attacks.
The Mayo Clinic recommends verapamil as a suitable medication for the management of angina, highlighting its effectiveness in improving quality of life for individuals with this condition.
3.3. Migraine Prophylaxis
Verapamil has also shown promise in the prevention of migraines, particularly in individuals who experience frequent or severe headaches. By regulating the constriction and dilation of blood vessels in the brain, verapamil may help reduce the frequency and intensity of migraines, providing relief to patients suffering from this debilitating condition.
A study published in the Journal of Headache and Pain demonstrated the efficacy of verapamil in reducing migraine frequency and severity, supporting its use as a preventive therapy for migraine sufferers.
Overall, Calan (Verapamil) is a versatile medication with proven benefits in treating hypertension, angina, and migraine prophylaxis. Its effectiveness in these conditions underscores its importance in modern healthcare practices.
