Metoprolol and Hydrochlorothiazide (Oral)

As a diuretic and a beta-blocker, the Metoprolol and Hydrochlorothiazide combination can be an effective form of treatment for some patients suffering from hypertension.

Overview

Metoprolol and Hydrochlorothiazide is a drug combination that is given to patients suffering from hypertension (high blood pressure). If you do suffer from this then it is important that you seek suitable medical treatment. If left untreated, hypertension can lead to some very severe medical problems such as heart attacks, kidney failure, or strokes. This is because the high blood pressure increases the workload that your arteries and heart need to perform. Over time, this causes them to no longer be able to function properly, thus causing the aforementioned complications. However, by controlling your blood pressure, you can help prevent these from occurring.

The Metoprolol component of this drug combination is a beta-blocker. This means it can work by affecting the responses sent to certain nerve impulses in parts of your body. This includes the heart. As such, it can cause your heart to beat slower and decrease your blood pressure. By lowering your blood pressure, it allows more oxygen and blood to flow to your heart.

Hydrochlorothiazide is known as a water pill (or diuretic). This means that it can reduce the amount of water in your body by increasing your flow of urine. In turn, this also helps to lower your blood pressure.

Be aware that the Metoprolol and Hydrochlorothiazide combination is only available via a prescription from your doctor. It is only suitable for certain patients, and your doctor will need to first assess your suitability. Instead of this, they may find it more appropriate to prescribe an alternative form of hypertension medication.
