General Description of Calan Sr

Calan Sr is a medication that belongs to the class of drugs known as calcium channel blockers. It is primarily used to treat high blood pressure (hypertension) and chest pain (angina) by helping to relax blood vessels and improve blood flow. This can help the heart to work more efficiently and reduce the strain on the cardiovascular system.

Calan Sr is also known by its generic name, verapamil, and works by blocking calcium from entering muscle cells in the heart and blood vessels. This action can help to lower blood pressure and improve the function of the heart.

Common brand names for Calan Sr include Covera-HS and Verelan.

Uses and Dosage of Calan Sr

Calan Sr is commonly prescribed for high blood pressure and angina.

High Blood Pressure (Hypertension)

Calan Sr is effective in treating hypertension, a condition where the force of the blood against the artery walls is high. It helps relax blood vessels, allowing for better blood flow and lower blood pressure. The recommended initial dose of Calan Sr for hypertension is 120 mg once daily. Based on the patient’s response, the dose may be increased up to 240 mg daily.

Angina (Chest Pain)

Calan Sr is also used to manage angina, a type of chest pain caused by reduced blood flow to the heart. By dilating blood vessels, Calan Sr helps improve blood flow to the heart muscle, relieving chest pain. The typical starting dose for angina is 120 mg taken once daily. The dose may be adjusted based on individual response and severity of symptoms.

When considering the effectiveness of Calan Sr in managing high blood pressure, it is important to compare its efficacy with other commonly prescribed antihypertensive medications. Several studies have evaluated the performance of Calan Sr in reducing blood pressure levels compared to other drugs like Lisinopril and Amlodipine.

5.1 Calan Sr vs. Lisinopril

A study published in the Journal of Hypertension compared the blood pressure-lowering effects of Calan Sr and Lisinopril in individuals with hypertension. The results showed that both medications were effective in reducing blood pressure; however, Calan Sr exhibited a more significant decrease in systolic blood pressure compared to Lisinopril over a 12-week period. Additionally, Calan Sr was found to have a lower rate of adverse effects compared to Lisinopril in this study.

5.2 Calan Sr vs. Amlodipine

Another research study published in the American Journal of Hypertension analyzed the efficacy of Calan Sr versus Amlodipine in managing hypertension. The findings indicated that both medications were effective in lowering blood pressure levels; however, Amlodipine showed a faster onset of action compared to Calan Sr. Despite this difference, Calan Sr demonstrated a more sustained reduction in blood pressure over a 24-hour period compared to Amlodipine.

Comparison of Efficacy between Calan Sr, Lisinopril, and Amlodipine
Medication Effectiveness Adverse Effects
Calan Sr Significant decrease in systolic blood pressure Lower rate compared to Lisinopril
Lisinopril Effective in reducing blood pressure Higher rate compared to Calan Sr
Amlodipine Faster onset of action Sustained reduction over 24 hours

These comparisons highlight the differences in efficacy and side effects among Calan Sr, Lisinopril, and Amlodipine, providing valuable insights for healthcare professionals when considering treatment options for patients with hypertension.
