Have you been prescribed Ambrisentan? Let's talk about this medication in simple terms.

Has your doctor told you or someone close to you that you have Pulmonary Hypertension, or high blood pressure in the lungs? You may have been prescribed a pill called Ambrisentan. If you're a little confused by the name, don't worry. In this article, we'll explain everything about this medication in a very simple way, as if you were talking to a friend.

What exactly is Ambrisentan?

Simply put, ambrisentan is a medication that is used to treat a condition called Pulmonary Hypertension . Now you may be wondering what pulmonary hypertension is.

Imagine that there are small blood vessels that carry blood from our heart to our lungs. If these blood vessels become blocked or narrowed, the heart has to work harder to pump blood to our lungs. Just like when a water pipe becomes blocked, it becomes difficult for the water to flow. This causes the pressure inside those blood vessels to increase excessively. This is what we call pulmonary hypertension.

Ambrisentan works by relaxing and widening the narrowed blood vessels. This allows the heart to pump blood to the lungs more easily and without much effort. As a result, your symptoms such as fatigue and shortness of breath are reduced, and your ability to exercise and perform daily activities is improved.

Things you need to tell your doctor before taking this medicine

Before prescribing Ambrisentan to you, your doctor will need to know your complete medical history. Be sure to tell your doctor if you have any of the following conditions:

• If you are pregnant or trying to get pregnant: This is the most important thing. This medicine can cause very serious birth defects in the baby in the womb. So we will talk about this in detail later.
• If you are a breastfeeding mother: This medicine can pass into breast milk, so it is not recommended during breastfeeding.
• Liver disease: If you have any liver disease, you should tell us about it, as the liver plays a major role in removing this medication from the body.
• Anemia: This means a lack of blood. This medicine can sometimes reduce the number of red blood cells in the blood. So if you already have anemia, your doctor should be aware of it.
• Pulmonary veno-occlusive disease (PVOD): This is a very rare but serious condition involving the blood vessels in the lungs. Your doctor should also be aware of this.
• Allergies to other medicines or foods: Tell your doctor if you have any allergies to Ambrisentan or any other medicine, food, or dye.

How should I use the medicine?

The method of using this medicine is very simple.

• Swallow this pill with a glass of water.
• Try to take the medicine at the same time every day. This will help keep the medicine working at the same level.
• This medicine can be taken before or after meals. However, if you experience stomach upset, it is best to take it with food.
• Do not stop taking the medicine until your doctor tells you to. It is important to continue taking it even if your symptoms improve.

What if you miss a dose of medicine?

If this happens, don't worry. Take the missed dose as soon as you remember. But if it is almost time for your next dose, skip the missed dose and take the next dose at the scheduled time. Never take two doses at once (Do not take double doses).

What if I take too much medicine?

If you think you have overdosed, immediately call the National Poisons Information Centre at the Colombo National Hospital . Or, go to the Emergency Department (ETU) of the nearest hospital.
