CTD T 6.25/40mg Tablet 15'S

Introduction About CTD T 6.25/40MG TABLET

CTD T 6.25/40 mg Tablet is a combination medicine formulated for people who require effective control of high blood pressure (hypertension), particularly when a single antihypertensive medication is insufficient. It contains telmisartan, an angiotensin II receptor blocker, and chlorthalidone, a thiazide-like diuretic. Together, these ingredients help relax blood vessels and remove excess fluid from the body, supporting stable blood pressure levels and reducing the risk of complications such as heart disease, stroke, and kidney damage.

This tablet is ideal for adults diagnosed with essential hypertension, especially those who may benefit from a dual-action approach. Patients who have not achieved adequate blood pressure control with a single drug or those with fluid retention issues may find this combination particularly helpful. It is not typically recommended for children or individuals with severe kidney problems unless advised by a doctor.

CTD T 6.25/40 mg Tablet is usually taken once daily, preferably in the morning, with or without food. Swallow the tablet whole with water and try to take it at the same time every day. Regular blood pressure monitoring is advised to ensure the medicine is working effectively. If a dose is missed, take it as soon as remembered, unless it is near the next scheduled dose. Do not double the dose.

Before starting this medicine, inform your doctor if you have kidney or liver problems, electrolyte imbalances, or heart conditions. It is not recommended during pregnancy and should only be used during breastfeeding if clearly advised by a healthcare professional. Common side effects may include dizziness, headache, increased urination, or mild tiredness. Drinking adequate water, avoiding sudden position changes, and limiting alcohol can help reduce side effects. Regular check-ups and lab tests may be required to monitor kidney function and electrolyte levels.

CTD T 6.25/40 mg Tablet for Hypertension

CTD T 6.25/40 mg Tablet is prescribed for managing high blood pressure, especially when a single medicine is not sufficient.

How CTD T 6.25/40MG TABLET Works

Mechanism of Action of CTD T 6.25/40 mg Tablet

CTD T 6.25/40 mg Tablet is a combination of telmisartan and chlorthalidone, which work together to support effective blood pressure control.

Telmisartan belongs to a group of medicines called angiotensin II receptor blockers (ARBs). It works by blocking the action of angiotensin II, a substance that causes blood vessels to narrow. By preventing this action, telmisartan helps blood vessels relax and widen, allowing blood to flow more smoothly and reducing pressure within the vessels. Chlorthalidone is a thiazide-like diuretic that helps the body remove excess salt and water through urine. By reducing extra fluid in the blood vessels, it lowers the volume of circulating blood, which further supports a reduction in blood pressure.

Together, these two components provide a complementary effect relaxing blood vessels and reducing fluid overload to help maintain stable blood pressure levels when taken regularly as advised by a doctor.
