Fosinopril and Hydrochlorothiazide (Oral)

Overview

Fosinopril and Hydrochlorothiazide is a drug combination used by patients looking to reduce hypertension (high blood pressure). Doing so is important as ongoing high blood pressure puts pressure on arteries and the heart by adding to their workload. If left untreated, hypertension can cause the heart and arteries to be unable to properly function. In turn, this can damage the blood vessels in the kidneys, brain and heart, leading to heart failure, kidney failure or strokes.

Ongoing high blood pressure can also lead to an increased risk of heart attacks. If properly controlled, patients can hopefully avoid such unwanted problems. The Hydrochlorothiazide element of this combination works by helping reduce the levels of water and salt in the body. It does this by helping the kidneys to increase the urine flow. At the same time, Fosinopril blocks a certain enzyme in your body which itself creates a substance that makes blood vessels become tighter. By doing this, blood vessels are able to relax.

Combined together, these two drugs have the effects of lowering blood pressure and increasing the supply of oxygen and blood to your heart. Do be aware that you cannot obtain the Fosinopril and Hydrochlorothiazide combination yourself, you will need a doctor's prescription. It has the ability to interact with a variety of different drugs and can cause a number of side effects to occur. As such, it is only suitable for certain patients.
