What is DynaCirc?

DynaCirc is a prescription medicine used to treat high blood pressure (hypertension). DynaCirc may be used alone or with other blood pressure medicines.

High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure can also cause an aneurysm (broken blood vessel) to form in the brain or abdominal aorta (the large artery that carries blood from the heart through the abdomen to the rest of the body).

Health Benefits

DynaCirc can help lower your blood pressure. Lowering your blood pressure reduces your risk of stroke, heart attack, and kidney problems.

Other health benefits of DynaCirc may include:

– improved blood flow

– reduced risk of heart failure

– reduced risk of stroke

– reduced risk of kidney disease

– reduced risk of aneurysm

– improved blood pressure control

Side Effects

DynaCirc is generally well-tolerated, but some people may experience side effects. The most common side effects include:

– headache

– dizziness

– fatigue

– nausea

– diarrhea

If you experience any of these side effects, talk to your doctor. They may be able to recommend ways to reduce or prevent them. Serious side effects are rare, but if you experience any of the following, call your doctor immediately:

– shortness of breath – chest pain – irregular heartbeat – swelling in the hands, feet, ankles, or lower legs – yellowing of the skin or eyes – dark urine – unusual bleeding or bruising


DynaCirc is available in tablet form. The usual starting dose is 50 mg once daily. Your doctor may increase your dose depending on how well your blood pressure is controlled. The maximum recommended dose is 200 mg per day.

If you miss a dose of DynaCirc, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time.


DynaCirc can interact with other medications, vitamins, or herbs you may be taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well.

To help avoid interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs you’re taking. To find out how this drug might interact with something else you’re taking, talk to your doctor or pharmacist.

If you have questions about drug interactions that may affect you, ask your doctor or pharmacist.

Mechanism of Action

DynaCirc works by blocking the action of certain chemicals in the body that tighten blood vessels. This relaxes the blood vessels and lowers blood pressure.


DynaCirc is absorbed quickly and completely from the gastrointestinal tract. Peak plasma concentrations are reached within 1-2 hours. DynaCirc is widely distributed throughout the body and crosses the blood-brain barrier. It is metabolized in the liver and excreted in the urine. The elimination half-life is 12 hours.

Alternatives to DynaCirc

There are many alternatives to DynaCirc for the treatment of high blood pressure. Some common medications used to treat high blood pressure include:

– ACE inhibitors – angiotensin II receptor blockers (ARBs) – calcium channel blockers (CCBs) – diuretics – beta blockers

Your doctor can help you choose the best medication for you based on your medical history and current health condition.

Clinical Trials

DynaCirc has been studied in two clinical trials. In the first trial, 1,600 people with high blood pressure were randomly assigned to receive either DynaCirc or a placebo. The study found that DynaCirc was more effective than the placebo at lowering blood pressure.

The second trial was a large, international study of over 8,000 people with high blood pressure. This study found that DynaCirc was more effective than a placebo at lowering blood pressure and reducing the risk of heart attack, stroke, and death.
