Diltiazem Hydrochloride SR Tablets 90 Mg

What Are Diltiazem Hydrochloride SR Tablets 90 Mg?

Diltiazem Hydrochloride SR (sustained-release) Tablets 90 Mg are oral prescription medicines in the class of calcium channel blockers (CCBs). They are formulated to release diltiazem gradually over time to help maintain stable blood levels throughout the day.

Diltiazem is commonly prescribed to:

• Lower high blood pressure (hypertension)

• Relieve angina (chest pain)

• Assist with heart rate control in certain arrhythmias

The sustained-release formulation provides a smoother pharmacologic effect, allowing for less frequent dosing and improved tolerability compared to immediate-release forms.

This medication should be taken exactly as prescribed by a licensed healthcare provider.

How Diltiazem Works

1. Calcium Channel Blockade

Diltiazem inhibits the flow of calcium ions into vascular smooth muscle and cardiac muscle cells. Calcium is essential for muscle contraction; blocking its entry leads to relaxation of the vascular walls and heart muscle.

2. Vasodilation

Relaxed blood vessels widen (vasodilation), which reduces resistance to blood flow and helps lower high blood pressure.

3. Cardiac Conduction Modulation

In addition to vascular effects, diltiazem can slow conduction through the atrioventricular (AV) node. This helps control certain heart rate irregularities, particularly in arrhythmias.

The sustained-release formulation helps maintain steady effects over time.

Sustained-release cardiovascular care models may include Diltiazem Hydrochloride ER Capsules 120 Mg within long-term management planning.

Indications

A qualified healthcare provider may prescribe Diltiazem Hydrochloride SR Tablets 90 Mg for:

• Hypertension (high blood pressure)

• Chronic stable angina

• Rate control in specific arrhythmias (e.g., atrial fibrillation)

Clinical decisions are individualized based on patient history, comorbidities, and risk profile.

Long-term cardiovascular care strategies may incorporate Diltiazem Hydrochloride ER Tablets 60 Mg as part of structured clinical planning.

Dosage & Administration

⚠ Follow your healthcare provider’s instructions.

• Taken typically once or twice daily depending on clinical guidance

• Can be taken with or without food

• Always swallow whole — do not crush or chew

Missed dose:
Take as soon as remembered unless it is close to your next dose. Do not use an extra dose to make up.

Clinical Benefits

Under medical guidance, this medication may:

• Help lower elevated blood pressure

• Reduce frequency and severity of angina

• Assist in controlling abnormal heart rhythms

• Provide smoother, sustained drug levels due to SR formulation

Individual responses vary with clinical context and co-existing health conditions.

Safety Information & Precautions

Before beginning treatment, inform your clinician if you have:

• Heart failure or left ventricular dysfunction

• Severe hypotension (low blood pressure)

• AV conduction abnormalities (e.g., heart block)

• Liver or kidney impairment

• Pregnancy or plans for pregnancy

Respiratory disease management follows global healthcare frameworks established by the World Health Organization (WHO).

Important Safety Notes

• May cause dizziness, headache, or flushing

• Monitor blood pressure and heart rate regularly

• Avoid abrupt discontinuation

• Use caution when operating vehicles or machinery

Possible Side Effects

Common side effects may include:

• Dizziness

• Headache

• Flushing

• Peripheral edema (swelling of legs or feet)

• Fatigue

Seek medical care if you experience:

• Severe hypotension symptoms

• Worsening chest pain

• Rapid or irregular heartbeat

• Signs of allergic reaction (rash, swelling)

Always work with your healthcare provider to evaluate side effects.

Drug Interactions

Tell your clinician about all medicines, supplements, and herbal products you take, including:

• Beta-blockers

• Other calcium channel blockers

• Digoxin

• Antihypertensive medicines

• Alcohol

Interactions may alter how the medication works or increase side effect risks.

Use in Special Populations

Pregnancy & Breastfeeding

Consult your healthcare professional. Cardiovascular medications during pregnancy and lactation require individualized evaluation and may only be used when clearly needed.

Elderly Patients

Older adults may have increased sensitivity to blood pressure and heart rate changes; clinical monitoring may be required.

Liver or Kidney Impairment

Dose adjustments and monitoring may be needed based on clinical assessment.

Monitoring & Follow-Up

Your healthcare provider may:

• Monitor blood pressure regularly

• Check heart rate and rhythm

• Evaluate liver and kidney function if indicated

• Adjust dosage as necessary

Regular follow-up helps ensure optimal safety and effectiveness.

Storage Instructions

• Store in a cool, dry place below 25°C

• Keep in original packaging

• Protect from moisture and direct sunlight

• Keep out of reach of children
