Cardizem LA (diltiazem) is an extended-release blood pressure reducing drug available only with a prescription. Cardizem LA relaxes the muscles of the heart and dilates blood vessels.
Diltiazem is a type of popular blood pressure reducing medications called calcium channel blockers. The “calcium channel,” is the chemical mechanism that allows nerves to conduct electricity and muscles to contract. Calcium channel blockers, then, reduce the electrical signals and the muscle contractions in the heart, causing the heart to beat with less strength. Calcium channel blockers also relax blood vessel muscles, and so increase the width of the blood vessels. Both effects lower blood pressure.
Cardizem LA is also prescribed to patients with stable angina (chest pain) to increase their ability to exercise longer without chest pain.
Cardizem LA is taken as a tablet once per day in the morning or evening.
The most common physical side effects include but are not limited to headache, swelling, slow heartbeat, palpitations, flushing, dizziness, sore throat, stuffy nose, and coughing. Serious side effects, mental and mood changes, and allergic reactions are very rare.
