Table of contents:

Sular is a prescription medication used to treat high blood pressure (hypertension). By lowering high blood pressure, it helps prevent strokes, heart attacks, and kidney problems.It is available in the form of an extended-release tablet and is usually taken once a day.

Sular contains the active ingredient nisoldipine. Nisoldipine belongs to the class of drugs called calcium channel blockers. It works by relaxing the blood vessels and decreasing the resistance in the blood vessels. This allows the blood to flow more easily, which lowers blood pressure.

Use and Dosage

Sular is an extended-release tablet to be taken by mouth, usually once daily, or as prescribed by your doctor. Take Sular on an empty stomach or with a low-fat meal. Swallow the tablets whole; do not crush or chew them, as doing so can release all the drug at once, increasing the risk of side effects.

The dosage of Sular will depend on your medical condition and response to treatment. Your doctor may gradually increase your dose, so follow their instructions carefully. Use Sular regularly to get the most benefit from it and try to take it at the same time each day to help you remember. Even if you feel well, continue taking Sular as directed by your doctor, as most people with high blood pressure do not feel sick.

If your condition does not improve or worsen (for example, your routine blood pressure readings remain high or increase), inform your doctor immediately.
