Product Description

Calaptin 80mg (Verapamil) – Affordable Calan Alternative

Calaptin 80mg is used for the treatment of patients with hypertension (high blood pressure), angina (heart-related chest pain), and some types of irregular heartbeats (arrhythmias).

In the treatment of hypertension: Calaptin relaxes the blood vessels, allowing more blood to circulate easily around your body. This lowers your blood pressure and significantly reduces the risk of having a heart attack, stroke, or kidney problems in the future. You do not feel any direct beneficial effects from taking this antihypertensive agent, but it works in the long term to keep you well.
In treatment of arrhythmia: In case of abnormal heart rhythms, Calaptin works by stopping an abnormal rhythm while it is happening or preventing its occurrence.
Calaptin helps treat angina (heart-related chest pain): This medication is effective in treating and preventing heart-related chest pain. It causes relaxation and widening of blood vessels in the heart. This allows more blood to flow to the heart, so it receives more oxygen. This medicine enhances your ability to exercise and makes it easy for you to go with your daily life routine. It should be taken regularly to be effective.

Working of the calaptin 80mg:

The active ingredient of the medicine is Verapamil, which functions by relaxing blood vessels to reduce blood pressure. This action helps to reduce the workload of the heart.

Precautions

Calaptin 80 mg extended-release tablet is contraindicated in certain conditions/situations. These include severe ventricular dysfunction, hypotension, sick sinus syndrome, second- or third-degree AV block, and atrial flutter or fibrillation. Also, the medicine should not be used in patients with hypersensitivity to Verapamil or any other ingredients.

Since the medication is highly metabolized in the liver, it should be used carefully in patients with impaired liver function. Calaptin's dosage may need to be reduced when used in patients with attenuated neuromuscular transmission.

The medication should be used cautiously in patients with insufficient kidney function.

Drug interactions may occur:

Coadministration of Verapamil and Ivabradine should be avoided.
For hypertensive patients, the risks associated with combined treatment may outweigh the benefits. Note that the combination of Verapamil and other blood pressure medicines should only be used with caution and should require close monitoring.
Calaptin, when used concomitantly with oral antihypertensive medicines such as angiotensin-converting enzyme inhibitors, beta-blockers, and diuretics, will usually induce an addictive effect on lowering blood pressure levels. Patients getting these combination medicines should be monitored closely. Concomitant use of medications may result in a significant drop in blood pressure that is excessive in some patients.
Coadministration with Flecainide may result in unwanted effects; hence, it should be avoided.
The combined use of Quinidine and Verapamil may result in significant hypotension.
Also, let your healthcare provider know of some other medications before you take Calaptin. These include cyclosporin, lithium, nitrates, cimetidine, rifampin, theophylline, carbamazepine, phenobarbital, clonidine, telithromycin, neuromuscular blocking agents, etc.

Because there are no adequate research studies on pregnant women, this medication should only be used during pregnancy when clearly required. The medication is excreted in breast milk. Because of the risk of developing side effects in nursing infants from Calaptin, nursing should be discontinued while the medication is used.

The safety and effectiveness of this medicine in paediatric patients below the age of 18 years have not been established. Alcohol consumption should be avoided while taking this medication as it may cause worsening side effects.

FAQ

What is verapamil 80 mg prescribed for?

Verapamil 80 mg (Calaptin 80mg) is a non-dihydropyridine calcium channel blocker used to treat hypertension, stable and unstable angina, and cardiac arrhythmias including paroxysmal supraventricular tachycardia (SVT) and atrial fibrillation. The 80 mg dose is an intermediate strength offering stronger rate control than 40 mg while staying within a range suitable for multiple daily doses. It is the generic equivalent of Calan 80mg at a significantly reduced cost.

How does verapamil 80 mg help control heart rhythm?

Verapamil 80 mg slows electrical conduction through the atrioventricular (AV) node by blocking calcium influx in nodal cells. This interrupts the rapid impulse conduction responsible for reentrant arrhythmias, converting SVT to normal sinus rhythm or slowing the ventricular response in atrial fibrillation. Its negative chronotropic effect reduces heart rate without affecting the sinoatrial node as aggressively as beta-blockers, making it a useful option for rate control in selected arrhythmia patients.

How many times a day is verapamil 80 mg taken?

Verapamil 80 mg immediate-release tablets are typically taken two to three times daily, spaced approximately 8 hours apart, to maintain consistent therapeutic blood levels. For hypertension, a common regimen is 80 mg three times daily, totalling 240 mg per day. Your prescribing physician will set the exact schedule based on your condition and response. Taking doses with meals reduces nausea and gastrointestinal discomfort associated with verapamil.

How long does verapamil 80 mg take to slow a fast heart rate?

Oral verapamil 80 mg typically reaches peak plasma concentrations within 1–2 hours of ingestion. Its heart rate-slowing effect becomes noticeable within this window, particularly in patients with elevated resting heart rates. For arrhythmia management, measurable rate control usually develops within the first 1–2 days of regular dosing. Full therapeutic stabilisation, especially for blood pressure, generally requires consistent use over 1–2 weeks.

Is verapamil 80 mg safe during pregnancy?

Verapamil is generally classified as FDA Category C in pregnancy, meaning it should only be used when clearly needed and when benefits outweigh potential risks. Limited data suggest it can be used cautiously during pregnancy, particularly in the second and third trimesters, to manage arrhythmias when safer alternatives have failed. However, it should not be the first-choice antihypertensive in pregnant patients. Always consult an obstetrician and cardiologist before taking verapamil during pregnancy.

Can verapamil 80 mg interact with statins?

Yes. Verapamil inhibits CYP3A4, the liver enzyme responsible for metabolising several statins — particularly simvastatin and lovastatin. This interaction can significantly raise statin blood levels, increasing the risk of muscle pain, weakness, or the rare but serious condition rhabdomyolysis. If you take verapamil and need a statin, your doctor will likely prescribe pravastatin or rosuvastatin, which are not significantly metabolised by CYP3A4, minimising this interaction risk.

How does Calaptin 80mg compare to diltiazem for heart rate control?

Both Calaptin 80mg (verapamil) and diltiazem are non-dihydropyridine calcium channel blockers used for heart rate control. Verapamil tends to have a more pronounced negative inotropic effect (reduced cardiac contractility), while diltiazem is generally better tolerated in patients with mildly reduced ejection fraction. For pure rate control in atrial fibrillation, both are effective, but cardiologists often consider individual patient profiles — particularly left ventricular function — when choosing between them.

Is verapamil 80 mg a good alternative to Calan 80mg?

Yes. Calaptin 80mg offers identical cardiovascular benefits to Calan 80mg at a fraction of the cost. Both contain verapamil hydrochloride 80 mg and meet bioequivalence requirements set by regulatory agencies. For patients on fixed incomes or without comprehensive insurance, generic verapamil like Calaptin 80mg represents a practical and equally effective alternative to branded Calan, particularly given that verapamil is typically taken multiple times daily.

What are the most common side effects of verapamil 80 mg?

Constipation is the most frequently reported side effect of verapamil, occurring in approximately 25–30% of patients at the 80 mg dose. Other common effects include nausea, dizziness, bradycardia (slow heart rate), headache, and peripheral edema. Verapamil's negative inotropic properties can exacerbate symptoms in patients with borderline heart function. If you notice irregular heartbeats, significant fatigue, or swelling that worsens over time, consult your cardiologist promptly.

What precautions should patients taking verapamil 80 mg be aware of?

Patients on verapamil 80 mg should avoid combining it with beta-blockers without cardiologist guidance, as this can cause dangerous slowing of the heart. Regular ECG monitoring is advisable to detect AV block. Alcohol can potentiate verapamil's blood pressure-lowering effect, increasing dizziness risk. Grapefruit juice raises verapamil levels unpredictably and should be avoided. Patients with liver disease need dose adjustments, as verapamil is extensively metabolised by the liver.
