Uses of Carca Tablet CR

Benefits of Carca Tablet CR

Treatment of Angina (heart-related chest pain)
Carca CR 40 Tablet relaxes the blood vessels so that blood can flow more easily around your body and makes sure that your heart is getting a good supply of oxygen. This makes it less likely that you will suffer chest pain caused by angina. This medicine can help increase your ability to exercise and go about your daily life more easily by reducing the frequency of angina attacks. You should take it regularly and as long as it is prescribed for it to work effectively.

Treatment of Hypertension (high blood pressure)
Carca CR 40 Tablet works by blocking the effects of some chemicals on your heart and blood vessels. It slows down your heart rate and helps the heart to beat with less force. This lowers your blood pressure and helps in reducing your risk of having a stroke, a heart attack, other heart problems, or kidney problems in the future. This medicine needs to be taken regularly to be effective, so keep taking it even if you feel well. Do not stop without talking to your doctor.

Treatment of Heart Failure
Heart failure means your heart is weak and cannot pump enough blood to your lungs and the rest of your body. The most common symptoms are breathlessness, tiredness, and swelling in your legs, ankles, abdomen, and other parts of your body. Carca CR 40 Tablet makes it easier for your heart to pump blood around your body and is, therefore, effective treatment for heart failure.
