Verapamil SR 240: A Comprehensive Overview
Verapamil SR 240 is a sustained-release formulation of verapamil, a calcium channel blocker. It’s primarily used to manage hypertension (high blood pressure) and angina (chest pain). This extended-release design ensures a steadier drug level in your bloodstream, minimizing fluctuations and potentially improving efficacy.
Dosage varies depending on individual needs and medical conditions. Your doctor will determine the appropriate dose and monitor your response. Typical starting doses are lower and gradually increased as needed.
Condition | Typical Starting Dose (mg/day) | Maximum Dose (mg/day) |
---|---|---|
Hypertension | 120 | 480 |
Angina | 120 | 480 |
Common side effects include headache, dizziness, constipation, and nausea. These are usually mild and transient. However, report any severe or persistent side effects to your doctor immediately. Serious side effects, though rare, include heart block and low blood pressure. Consult your doctor promptly if you experience symptoms like severe dizziness or fainting.
Verapamil SR 240 interacts with several medications. It’s crucial to inform your doctor about all the medications, including over-the-counter drugs and herbal supplements, you are taking. Grapefruit juice can significantly impact Verapamil SR 240 levels, so avoid it during treatment. Regular blood pressure monitoring and other relevant checks are often needed to manage treatment.
Before starting Verapamil SR 240, discuss your medical history, including any heart conditions, liver or kidney problems, or allergies. Pregnancy and breastfeeding should be discussed with your doctor to assess the risk-benefit ratio.

Understanding Verapamil SR 240’s Mechanism of Action
Verapamil SR 240 works by blocking calcium channels in the heart and blood vessels. This action has several key effects.
Impact on the Heart
- Slows heart rate: Verapamil reduces the speed at which the heart beats by slowing the conduction of electrical impulses through the heart’s conductive system.
- Reduces contractility: The drug lessens the force with which the heart muscle contracts, decreasing the workload on the heart.
These effects are particularly beneficial for conditions like hypertension and angina where a slower, less forceful heartbeat is advantageous.
Impact on Blood Vessels
- Dilates blood vessels: By blocking calcium channels in the smooth muscle cells of blood vessels, Verapamil causes vasodilation, widening blood vessels and reducing blood pressure.
- Reduces peripheral resistance: This vasodilation lowers the resistance to blood flow, making it easier for the heart to pump blood throughout the body.
This action is critical in managing hypertension and improving blood flow to tissues.
Extended-Release Formulation
The “SR” in Verapamil SR 240 denotes sustained release. This formulation provides a consistent level of the drug in the bloodstream over a longer period, typically 24 hours, minimizing fluctuations in therapeutic levels and potentially reducing side effects. This allows for once-daily dosing convenience.
Specific Considerations:
- Dosage should always be determined by a healthcare professional based on individual needs and health conditions.
- Regular monitoring is crucial to track treatment efficacy and identify any potential side effects.
- Verapamil SR 240 interacts with other medications; consult your doctor before combining it with other drugs.
Summary:
Verapamil SR 240’s mechanism involves calcium channel blockade, leading to decreased heart rate, reduced contractility, vasodilation, and reduced peripheral resistance. This ultimately helps manage conditions like hypertension and angina through its sustained-release profile, ensuring consistent therapeutic levels throughout the day. Always consult a medical professional for appropriate use and monitoring.
Common Uses and Indications for Verapamil SR 240
Verapamil SR 240, a sustained-release formulation of verapamil, primarily treats hypertension (high blood pressure). It effectively lowers blood pressure by relaxing blood vessels, reducing the heart’s workload.
Treating Angina
This medication also manages chronic stable angina. By slowing the heart rate and reducing the force of contractions, it decreases the heart’s oxygen demand, alleviating chest pain associated with angina.
Managing Arrhythmias
Verapamil SR 240 finds application in managing certain types of abnormal heart rhythms, specifically supraventricular tachycardias. It works by slowing the electrical impulses that trigger rapid heartbeats. Doctors carefully select patients for this application.
Migraine Prevention (Off-label)
While not its primary indication, some physicians may prescribe Verapamil SR 240 off-label for migraine prophylaxis. Its impact on calcium channels might help reduce migraine frequency and severity. However, discuss this use specifically with your doctor.
Remember, this information is for general knowledge and does not replace professional medical advice. Always consult your physician before starting or altering any medication regimen. They will assess your individual needs and determine the appropriate dosage and suitability of Verapamil SR 240 for your specific condition.
Potential Side Effects and Precautions with Verapamil SR 240
Consult your doctor immediately if you experience severe dizziness, lightheadedness, or fainting. These could indicate a significant drop in blood pressure.
Verapamil SR 240 can cause constipation. Increase your fluid and fiber intake to mitigate this. If constipation persists, contact your doctor.
Headaches are a common side effect. Over-the-counter pain relievers may help, but persistent headaches warrant medical attention.
Heart problems such as bradycardia (slow heart rate) can occur. Your doctor will monitor your heart rate regularly. Report any unusual heart palpitations or chest discomfort.
Verapamil SR 240 can interact with other medications, notably grapefruit juice and certain antidepressants. Inform your doctor of all medications and supplements you’re taking.
Nausea and vomiting are possible. Small, frequent meals might help. Severe or persistent nausea requires medical evaluation.
Liver and kidney function should be monitored, especially with long-term use. Your doctor will conduct necessary tests.
Avoid sudden cessation of Verapamil SR 240. Gradual tapering under medical supervision is necessary to prevent withdrawal symptoms such as increased blood pressure.
Inform your doctor if you have a history of heart block, severe heart failure, or low blood pressure before starting Verapamil SR 240.
This information does not replace professional medical advice. Always consult your doctor or pharmacist for personalized guidance.
Dosage and Administration Guidelines for Verapamil SR 240
Always follow your doctor’s prescription. Typical starting dose is 240 mg once daily. Your doctor may adjust this based on your response and condition. Take Verapamil SR 240 whole; do not crush, chew, or break the tablets. This ensures controlled release of the medication throughout the day. Swallow the tablet with a full glass of water.
Adjusting Your Dose
Your doctor will monitor your blood pressure and heart rate regularly. Dose adjustments are made gradually to minimize side effects. Increases are usually small, often 240 mg increments, with a maximum daily dose depending on your specific condition and response to treatment. Never change your dosage without consulting your physician.
Missed Dose
If you miss a dose, take it as soon as you remember, unless it is almost time for your next dose. Never double the dose to make up for a missed one. Consistent dosing is crucial for maintaining therapeutic levels. Contact your doctor if you frequently miss doses.
Interactions and Contraindications of Verapamil SR 240
Always inform your doctor about all medications you are taking, including over-the-counter drugs, herbal supplements, and even grapefruit juice. Verapamil SR 240 interacts significantly with several drug classes. Concurrent use with beta-blockers can severely lower heart rate and blood pressure, potentially leading to bradycardia and hypotension.
Combining Verapamil SR 240 with other calcium channel blockers, like diltiazem, intensifies their effects, increasing the risk of hypotension and bradycardia. Similarly, concurrent use with digoxin increases the risk of digoxin toxicity. Avoid concurrent use with strong CYP3A4 inhibitors like ketoconazole or ritonavir; this combination significantly raises Verapamil levels, increasing the risk of side effects.
Furthermore, avoid grapefruit juice as it inhibits the metabolism of Verapamil, leading to elevated blood levels. This medication should be used cautiously in patients with impaired liver or kidney function due to its potential for increased toxicity. Patients with sick sinus syndrome, second- or third-degree atrioventricular block (unless they have a pacemaker), or severe bradycardia should not take Verapamil SR 240.
Pregnant or breastfeeding women need to consult their doctor before using Verapamil SR 240, as its safety during pregnancy and lactation isn’t fully established. Patients with severe hypotension or heart failure should also exercise caution and closely monitor their condition while taking this medication. Always discuss potential risks and benefits with your physician before starting treatment with Verapamil SR 240.
