Calan SR 240 Tab: Managing Cardiovascular Health with Verapamil
Introduction
Calan SR 240 Tab is a medication that contains verapamil, a calcium channel blocker. It is commonly prescribed to treat high blood pressure (hypertension), angina (chest pain), and certain heart rhythm disorders. By relaxing blood vessels and improving blood flow, Calan SR 240 Tab helps manage these cardiovascular conditions effectively.
Mechanism of Action
Verapamil works by inhibiting the influx of calcium ions into the smooth muscle cells of the heart and blood vessels. This action leads to the relaxation of these muscles, resulting in:
Vasodilation: Widening of the blood vessels, which reduces blood pressure.
Decreased Heart Rate: Slowing down the heart rate, which helps in managing heart rhythm disorders.
Reduced Myocardial Oxygen Demand: Lowering the heart’s oxygen requirements, which alleviates angina symptoms.
Uses
Calan SR 240 Tab is used to treat several cardiovascular conditions, including:
High Blood Pressure (Hypertension): By relaxing blood vessels, verapamil helps lower blood pressure, reducing the risk of stroke, heart attack, and kidney problems.
Angina (Chest Pain): Verapamil improves blood flow to the heart, reducing the frequency and severity of angina attacks.
Heart Rhythm Disorders: It is effective in treating certain types of arrhythmias, such as atrial fibrillation and supraventricular tachycardia, by regulating the heart rate.
Dosage and Administration
The typical dosage of Calan SR 240 Tab is one tablet taken once daily. It is important to follow the prescribing doctor’s instructions and not to alter the dosage without medical advice. The tablet should be swallowed whole, preferably with food to enhance absorption and reduce the risk of gastrointestinal discomfort.
Side Effects
Common side effects of verapamil include:
Dizziness
Fatigue
Nausea
Constipation
Headache
Serious side effects, though rare, may include:
Severe hypotension (low blood pressure)
Bradycardia (slow heart rate)
Heart failure
Allergic reactions (e.g., rash, itching, swelling)
Precautions
Before taking Calan SR 240 Tab, inform your doctor if you have:
Heart conditions such as severe left ventricular dysfunction, sick sinus syndrome, or second- or third-degree AV block (without a pacemaker).
Liver or kidney disease.
A history of gastrointestinal disorders.
Interactions
Verapamil can interact with other medications, including:
Beta-blockers
Digoxin
Certain antiarrhythmics
Statins
Grapefruit juice (which can increase verapamil levels in the blood)
Conclusion
Calan SR 240 Tab, containing verapamil, is an effective medication for managing high blood pressure, angina, and certain heart rhythm disorders. By relaxing blood vessels and improving blood flow, it helps reduce the risk of serious cardiovascular events. As with any medication, it is important to use Calan SR 240 Tab under the guidance of a healthcare professional to ensure its benefits outweigh any potential risks.
