What Cordilox SR is used for
The name of your medicine is Cordilox SR. It is available as 180 mg and 240 mg tablets.
The letters SR in the name Cordilox SR stand for “sustained release”. This means the medicine is released into the blood over an extended period of time, usually allowing the medicine to be taken once a day.
Cordilox SR is used in the treatment of:
high blood pressure, also called hypertension
angina (chest pain)
Your doctor, may have prescribed Cordilox SR for another reason. Ask your doctor if you have any questions about why Cordilox SR has been prescribed for you.
Cordilox SR belongs to a group of medicines called calcium channel blockers or calcium antagonists. They work by opening up blood vessels which lets more blood and oxygen reach the heart and at the same time lowers high blood pressure.
Cordilox SR does not change the amount of calcium in your blood or bones. Calcium in your diet or in calcium supplements will not interfere with the way Cordilox SR works.
Cordilox SR is not recommended for use in children under the age of 18, as there have been no studies of its effects in this age group.
Cordilox SR is available only with a doctor’s prescription.
There is no evidence that Cordilox SR is addictive.
