What is Cardizem Sr

DiltiazemThe Generic name of this drug
Treatment SummaryDiltiazem is a drug used to lower blood pressure and treat heart conditions. It works by blocking the flow of calcium into the heart and blood vessels, resulting in relaxation of the muscles and widening of the blood vessels. It is approved by the FDA to treat hypertension, atrial fibrillation and atrial flutter, and chronic stable angina. It is also used off-label to treat anal fissures, migraine prevention, pulmonary hypertension, and rest-related cramps. Diltiazem is available in extended-release tablets and intravenous forms and is sold under the brand names Cardizem and Tiazac

Effectiveness

How Cardizem Sr Affects PatientsDiltiazem is a drug used to treat high blood pressure. It works by relaxing the walls of the blood vessels and reducing the pressure of the blood. It can also slow down the heart rate and increase the amount of blood flowing to the heart. Studies have shown that diltiazem can lower diastolic blood pressure by up to 8.6 mmHg when taken in doses of 540 mg per day. It has also been found to increase exercise tolerance in people with chronic stable angina, and reduce stroke risk in hypertensive patients.
How Cardizem Sr works in the bodyDiltiazem is a drug that helps reduce blood pressure and improve exercise tolerance. It works by blocking the influx of calcium into cells, which decreases the amount of calcium available in the body. This decrease in calcium reduces the contractions of cardiac and vascular smooth muscles, leading to vasodilation and reduced blood pressure. Additionally, diltiazem slows down the heart rate, which lowers the myocardial oxygen demand. All of these effects help to improve exercise tolerance and reduce blood pressure.

When to interrupt dosage

The recommended dose of Cardizem Sr is contingent upon the indicated condition, such as prophylaxis of migraine headaches, Fissure;Anal and Anginal Pain. The measure of dosage fluctuates according to the technique of administration featured in the table below.

Cardizem Sr Toxicity & Overdose RiskThe toxic amount of diltiazem in mice and rats is between 415-740mg/kg and 560-810mg/kg, respectively. In dogs, the toxic dose is greater than 50mg/kg and in monkeys, 360mg/kg is lethal. People have reported overdosing on doses ranging from less than 1g to 18g. Symptoms of overdose may include a slow heartbeat, low blood pressure, heart blockage, or cardiac failure which can cause dizziness, lightheadedness, and fatigue. Treatments for overdose involve supportive care such as administering fluids and vasopressors, as well as atropine

Patient Q&A Section about cardizem sr

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the difference between Cardizem CD and SR?

"The other product, Cardizem, releases the active ingredient more quickly, so it works over a shorter period of time (usually 6 to 8 hours) and must be taken more frequently (usually three or four times a day).

There are two different types of Cardizem, Cardizem CD and Cardizem. Cardizem CD is designed to release the active ingredient slowly so that it works over 24 hours and can be taken once a day. The other product, Cardizem, releases the active ingredient more quickly, so it works over a shorter period of time (usually 6 to 8 hours) and must be taken more frequently (usually three or four times a day)."

Answered by AI

Is Cardizem used to lower heart rate?

"Diltiazem works by slowing the heart rate and relaxing the blood vessels, which allows for more oxygen to reach the heart. This reduces the heart's workload and relieves chest pain."

Answered by AI

What is Cardizem SR used for?

"The capsules are used to treat high blood pressure and work by relaxing blood vessels in the body and heart so blood can flow more easily."

Answered by AI

What are the most common side effects of Cardizem?

"The following effects may occur: dizziness, lightheadedness, weakness, nausea, flushing, constipation, and headache. If you experience any of these effects for an extended period of time, or if they worsen, tell your doctor or pharmacist. To reduce your risk of dizziness and lightheadedness, stand up slowly when moving from a sitting or lying position."
