Buy Calaptin SR 240mg (Verapamil) Online
Calaptin standard release contains the active ingredient verapamil hydrochloride. This calcium ion influx inhibitor causes blood vessels to relax so that blood can flow more easily around your body.
It is indicated for the treatment of hypertension to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. Management of high blood pressure should be a part of comprehensive cardiovascular risk management, including, as appropriate, diabetes management, lipid control, exercise, smoking cessation, and limited sodium intake. Many patients require more than one medicine to achieve blood pressure goals. For specific advice on goals and management, contact your doctor.
Verapamil can be used as an initial agent in patients with beta-blockers. Diuretics are contraindicated in patients with medical conditions where these drugs frequently cause serious side effects.
Calaptin standard release tablets are contraindicated in the following conditions:
— Hypotension or cardiogenic shock
— Patients with known hypersensitivity to hydrochloride
— Severe left ventricular dysfunction
— Sick sinus syndrome
— Second or third-degree AV block
— Concomitant use of Calaptin SR with a diuretic or an angiotensin-converting enzyme (ACE inhibitors) is compatible and has additive blood pressure lowering effects.
Verapamil tablets should not be used concurrently with beta-adrenoreceptor blockers to treat hypertension.
Certain drugs may interact with Verapamil. These include:
— Beta-blockers such as metoprolol, propranolol, and atenolol
— Any other treatment for high blood pressure or arrhythmia (abnormal heartbeat), for example, quinidine, prazosin, disopyramide, hydrochlorothiazide and flecainide.
— Carbamazepine and phenobarbital. Clarithromycin, erythromycin, lithium, digitoxin, digoxin, almotriptan, colchicine, glyburide, etc.
— Certain medications can affect the immune system
— Some anti-cholesterol drugs
— Some HIV- antiviral medications
— Anti-cancer drugs
— Antidepressants
— Non-steroidal anti-inflammatory drugs
— Grapefruit juice
Caution should be exercised when Calaptin SR tablets are administered to elderly patients.
Along with needed effects, a medicine may cause undesired side effects too. Although not everyone who use Calaptin SR experience side effects. If they do occur, they may need immediate medical attention. Side effects reported with the use of Calaptin SR are headache, dizziness, ankle oedema, dyspepsia, sleep disturbance, rash, lethargy, and myalgia. Verapamil's most serious side effects are hypotension, heart failure, AV block, and rapid ventricular response.
Calaptin SR 240 mg is available for oral administration as tablets containing 240 mg of verapamil hydrochloride. The tablets are designed for extended release of the medicine in the gastrointestinal tract. It should be taken once daily at the same time each day. The usual adult dose is 180 to 240 mg per day. Take medicine with food to help it work better. The tablets should not be crushed, chewed, or divided. You do not usually feel any direct benefit from this antihypertensive agent, but it works in the long term to keep you well. Do not discontinue treatment with your doctor's advice, even if you feel well.
What is Calaptin SR 240mg used for?
Calaptin SR 240mg contains Verapamil 240mg in sustained-release form and is used for moderate-to-severe hypertension and chronic angina in adults. The 240mg dose is often prescribed when lower doses (120mg or 180mg) have not achieved adequate blood pressure control. It may also be used as part of rate-control therapy for atrial fibrillation under cardiologist supervision.
How does Calaptin SR 240mg compare to Calaptin SR 120mg?
Calaptin SR 240mg contains twice the Verapamil dose of the 120mg tablet. It is prescribed when the lower strength has not achieved blood pressure targets. Both are sustained-release formulations taken once or twice daily. The 240mg tablet provides a greater reduction in peripheral vascular resistance and heart rate. Close monitoring for bradycardia and hypotension is more critical at the 240mg dose.
What is the correct dosing regimen for Calaptin SR 240mg?
Calaptin SR 240mg is typically taken once daily (total daily dose 240mg) or up to twice daily for a total of 480mg per day in cases requiring intensive blood pressure control. It must be swallowed whole — never crushed or chewed. Take with food to minimise stomach upset. Maintain consistent timing to ensure stable blood levels throughout the day.
Is Calaptin SR 240mg better taken morning or evening?
Either morning or evening dosing is acceptable. Some cardiologists prefer once-daily evening dosing to provide maximum drug concentration during early morning hours when blood pressure and cardiovascular risk are highest. Alternatively, twice-daily dosing (morning and evening) provides more even 24-hour coverage. Discuss with your cardiologist which schedule best fits your blood pressure profile based on ambulatory readings.
Can Calaptin SR 240mg cause heart block?
Yes. At the 240mg sustained-release dose, Verapamil carries a risk of prolonging AV node conduction time, potentially causing first-degree, second-degree, or rarely third-degree heart block — particularly in patients with pre-existing conduction abnormalities. An ECG should be performed before starting high-dose Verapamil. Patients with bundle branch block or pre-existing AV block should use Verapamil with extreme caution or avoid it entirely.
Is Calaptin SR 240mg safe in older patients with hypertension?
Elderly patients are more sensitive to Verapamil's negative chronotropic effects (heart rate slowing). Calaptin SR 240mg can be used in older adults, but start with a lower dose and titrate slowly. Monitor resting heart rate and blood pressure more frequently. Falls risk due to orthostatic hypotension is a particular concern. Discuss the benefit-risk balance with a geriatric cardiologist.
How does Calaptin SR 240mg compare to Amlodipine 10mg?
Both are calcium channel blockers but work differently. Calaptin SR 240mg (Verapamil) reduces both heart rate and vascular resistance — useful when rate control is also needed. Amlodipine 10mg acts predominantly on peripheral vessels without significant heart-rate reduction. Verapamil has more drug interactions and requires more monitoring. Amlodipine is generally preferred for uncomplicated hypertension due to its simpler dosing and safety profile.
What makes Calaptin SR 240mg a cost-effective cardiac medication?
Calaptin SR 240mg from Abbott India offers branded-quality Verapamil sustained-release at significantly lower prices than Western originator brands. AllDayChemist sources directly from the manufacturer and ships worldwide to the USA, UK, and Australia, providing patients access to this essential cardiac medication without the high prices associated with brand-name CCBs.

What side effects should I watch for with Calaptin SR 240mg?
At 240mg, constipation and peripheral oedema (ankle swelling) are the most common side effects. Bradycardia, first-degree heart block, and hypotension become more likely than at lower doses. Dizziness, headache, and flushing may also occur. Gingival overgrowth can develop with long-term use. Contact your doctor promptly if your heart rate drops significantly or you feel unusually faint or weak.
What important warnings apply to Calaptin SR 240mg?
Calaptin SR 240mg is contraindicated in cardiogenic shock, severe heart failure, sick sinus syndrome (without pacemaker), and significant AV block. Avoid grapefruit as it substantially elevates Verapamil blood levels. The interaction with simvastatin is clinically significant — limit simvastatin to 10mg daily when using Verapamil. Never crush SR tablets. Do not discontinue abruptly — taper under medical supervision to avoid rebound angina.
