Istin contains the active ingredient amlodipine. It belongs to the class of medicines known as calcium antagonists.
Istin is used to lower blood pressure in patients with high blood pressure.
Istin increases blood flow to the heart muscle, which allows for more oxygen. As a result, chest pain is cured and prevented. Istin does not provide immediate relief of chest pain from angina.
It is best to take Istin with water either before or after eating. Take Istin at the same time every day. Grapefruit juice should not be taken with this medication.
Do not double up the dose for a missed dose. If you forget to take the medicine on time, and it's almost time for your next dose, skip the dose.
Your doctor will tell you how long you should take this medicine. If you stop taking this medicine sooner than you are advised, your condition could return.
Children and adolescents aged 6-17 years should take 2.5 mg daily as a starting dose. The maximum recommended daily dose is 5 mg. You can divide the Istin 5 mg tablet into half to get a 2.5mil dose.
