Cortiazem - Use | Dosage | Side Effects
Category Calcium channel blockers
Cortiazem is a medicine that contains active substance called diltiazem. This medicine blocks calcium channels and leads to dilation of blood vessels (vasodilation). Dilation of blood vessels facilitates blood flow, therefore reducing blood pressure. This is why it is used to treat high blood pressure and angina pectoris.
It cannot be used in the following conditions:
- Patients with AV (atrioventricular) block I, II or III level. Cortiazem can slow the heart rate and may lead to heart failure in these patients.
- In patients allergic to the active substance (diltiazem) or other similar medicines:
- verapamil and others.
- Patients with cardiogenic shock.
- Hypotension (low blood pressure).
- In patients with slow heart rate (bradycardia). It may further slow the heart rate and cause cardiac arrest.
It cannot be used concomitant with grapefruit, alcoholic beverages, or St. John's wort because these foods may change the efficacy of Cortiazem.
It can be used only with great caution in patients with liver or kidney disorders as well as in the patients with depression.
Cortiazem should be used for as long as your doctor recommended because high blood pressure usually causes no symptoms. However, it is very important that your blood pressure be within a healthy range, to reduce the risk of heart attack or stroke! In addition to using Cortiazem, your doctor will probably recommend you to change your life style:
- You need to exercise at least half an hour per day
- Stop smoking
- Avoid stress
- Increase your intake of fruits, vegetables, fish meat
- Avoid greasy, fatty and spicy foods
