How Zilarta Ct 40/12.5 works
Asar-CT 40/6.25 Tablet is a combination of two medicines: Azilsartan medoxomil and Chlorthalidone which lower blood pressure effectively. Azilsartan medoxomil is an angiotensin receptor blocker (ARB). It works by blocking the hormone angiotensin thereby relaxing blood vessels.This allows the blood to flow more smoothly and the heart to pump more efficiently. Chlorthalidone is a diuretic that removes extra water and certain electrolytes from the body. Over time it also relaxes blood vessels and improves blood flow.

Warnings and precautions
Stand up slowly for the first few days — dizziness on rising is common when you start or your dose goes up. Stop and seek urgent care if your lips, tongue, face or throat swell, or you have difficulty breathing. A persistent dry, tickly cough can be caused by the ACE inhibitor group; tell your doctor rather than stopping on your own, as an alternative exists. Your doctor will check your kidney function and potassium after starting and after any dose change. Do not use salt substitutes containing potassium without asking your doctor. Take it in the morning so that passing urine does not disturb your sleep. Your doctor will check your salts and kidney function with blood tests — do not skip them. Report muscle cramps, marked weakness, confusion or an irregular heartbeat; these can be signs your potassium or sodium has fallen. In hot weather or during an illness with vomiting or loose motions, tell your doctor — you may become dehydrated quickly.
Do not take Zilarta Ct 40/12.5 if
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Must not be used in pregnancy — it can seriously harm the developing baby. Not for people with narrowing of both kidney arteries, or a history of swelling of the face and throat caused by this group of medicines. Not for people who are unable to pass urine, or who are severely dehydrated.
Interactions with other medicines
Anti-inflammatory painkillers reduce the effect and can harm the kidneys when combined. Potassium supplements, potassium-sparing water tablets and salt substitutes can push potassium too high. Lithium levels rise when taken with these medicines. Anti-inflammatory painkillers blunt the effect and can strain the kidneys. Lithium and digoxin levels are affected; tell your doctor if you take either. Potassium-sparing types must not be combined with potassium supplements without supervision.
How to store Zilarta Ct 40/12.5
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Expert advice for Zilarta Ct 40/12.5
Blood pressure medicines work only while you take them — do not stop because you feel well. Tell your doctor at once if you become pregnant or are planning a pregnancy. Keep a home blood-pressure record if your doctor has asked for one. Weigh yourself at the same time each day if you have heart failure, and report a rapid gain. Do not add extra salt, and ask before using a potassium-based salt substitute.
