General description of Diltiazem:

Diltiazem, also known by its brand names Cardizem or Tiazac, is a medication commonly prescribed to manage high blood pressure and chest pain (angina). It belongs to a class of drugs called calcium channel blockers, which work by relaxing blood vessels and increasing blood flow to the heart.


  • Treatment of hypertension
  • Relief of angina symptoms
  • Prevention of certain types of abnormal heart rhythms

Mechanism of Action:

Diltiazem inhibits the influx of calcium ions through the cell membranes of cardiac and smooth muscle cells. This action results in dilation of coronary and systemic arteries, which reduces the workload on the heart and improves blood flow.

Forms and Dosage:

Diltiazem is available in various forms, including tablets, extended-release capsules, and injectable solutions. The dosage may vary depending on the individual’s condition and response to treatment.

Side Effects:

Common side effects of diltiazem may include dizziness, headache, flushing, and constipation. Serious side effects such as slow heart rate or fainting may occur in some individuals.

Drug Interactions:

Diltiazem has the potential to interact with other medications, especially those that affect heart rhythm or blood pressure. It is important to inform your healthcare provider about all the medications you are taking to avoid potential interactions.

Monitoring and Precautions:

Regular blood pressure monitoring is essential when taking diltiazem to ensure effective control of hypertension. Patients with certain heart conditions or liver problems may require special precautions while using this medication.

It is important to follow the instructions provided by your healthcare provider or pharmacist regarding the dosage and frequency of administration. Do not crush or chew extended-release tablets; swallow them whole with a glass of water.

Special Populations

For elderly patients or those with liver or kidney impairment, the initial dose of diltiazem may be lower to minimize the risk of side effects. Close monitoring is necessary in these populations to adjust the dosage accordingly.
