Cardizem SR Tablet 90 mg contains Diltiazem Hydrochloride, a sustained-release calcium channel blocker used to manage cardiovascular disorders such as hypertension, angina pectoris, and certain arrhythmias. The sustained-release (SR) formulation ensures a gradual and prolonged release of the active ingredient, allowing for once-daily dosing and maintaining steady therapeutic levels throughout the day. This enhances patient compliance while providing consistent blood pressure and heart rate control.

Diltiazem works by inhibiting the influx of calcium ions into cardiac and vascular smooth muscle cells, resulting in relaxation of blood vessels, reduced cardiac workload, and improved coronary blood flow. Additionally, it slows conduction through the atrioventricular (AV) node, helping to control rapid heart rates in supraventricular arrhythmias such as atrial fibrillation or atrial flutter.

Indications

Cardizem SR Tablet 90 mg is indicated for:

• Hypertension (high blood pressure) to reduce the risk of cardiovascular events such as stroke, myocardial infarction, and kidney damage

• Chronic stable angina to relieve chest pain and improve exercise tolerance

• Variant (Prinzmetal’s) angina caused by coronary artery spasms

• Supraventricular arrhythmias, including atrial fibrillation and atrial flutter, to control heart rate

• Prevention of recurrent angina attacks in patients with coronary artery disease

The SR formulation is particularly suitable for patients requiring steady blood pressure and heart rate control throughout the day with minimal dosing frequency.

Key Benefits

• Provides once-daily control of blood pressure and heart rate

• Reduces chest pain and frequency of angina attacks

• Improves oxygen delivery to the heart and overall cardiac function

• Controls heart rate in patients with supraventricular arrhythmias

• Sustained-release formulation enhances patient compliance

• Can be used alone or in combination with other cardiovascular medications

Dosage and Administration

The dosage of Cardizem SR Tablet 90 mg should be individualized based on patient condition, response, and coexisting health issues.

General administration guidelines:

• Adults: typically 90 mg once daily, with or without food, or as prescribed by a physician

• Swallow the tablet whole; do not crush, chew, or split the SR tablet

• Take at the same time every day for consistent therapeutic effect

• Monitor blood pressure, heart rate, and ECG regularly to assess response

Dose adjustments may be required for patients with liver impairment, heart block, or severe cardiac conditions.

Precautions

Before taking Cardizem SR Tablet, inform your doctor if you have:

• Severe bradycardia (slow heart rate) or AV block

• Heart failure or recent myocardial infarction

• Low blood pressure or hypotension

• Liver or kidney disease

• Pregnancy or breastfeeding

Caution is advised when using Cardizem with other antihypertensive, antiarrhythmic, or beta-blocker medications. Do not stop the medication abruptly without consulting a physician, as it may worsen angina or precipitate arrhythmias.
