Do you also have difficulty breathing due to asthma or allergies? Then let's learn about these Leukotriene Modifiers!

Sometimes, even a small amount of dust, pollen, or food can make you feel short of breath, chest tightness, or a constant cough. Maybe you have a runny nose, sneezing, or a scratchy throat. These are really annoying, aren't they? Most of the time, these symptoms are caused by a reaction in our body. Today, we're going to talk about a special type of medication that can help control breathing difficulties caused by conditions like asthma and allergies. They are called Leukotriene Modifiers .

What are leukotrienes? Why do they bother us?

Simply put, leukotrienes are chemicals that our bodies produce. They are not just produced by chance. Imagine, when you are allergic to something, that is, when something enters your body, for example, dust, pollen, certain foods, then our immune system suddenly activates and releases these leukotrienes.

It is when these leukotrienes are released that we start having problems. The respiratory system in particular is most affected. Let's see what happens:

• Cough: A persistent, sometimes painful cough may occur.
• Increased mucus: Fluids like mucus and phlegm start to accumulate in the chest and throat. This can cause a whistling sound when breathing.
• Swelling of the airways: Our airways, the places where we breathe, start to swell from the inside. Just like when a water pipe swells from the inside, the space for the water to flow through becomes smaller.
• Airway muscle spasm: The small muscles around the airways tighten and contract, making the airways even narrower.
• Chest tightness: It may feel like someone is squeezing your chest, like it's being squeezed.
• Difficulty breathing or wheezing: When all of the above are combined, breathing becomes very difficult. Some people may experience wheezing.

You see, these little chemicals called leukotrienes are causing us so much trouble.

So what are these leukotriene modifiers? What do these medications provide relief from?

Okay, now we know that leukotrienes are often responsible for these breathing problems. Leukotriene modifiers are a type of medication that controls and modifies the action of those leukotrienes. They are also called leukotriene receptor antagonists or leukotriene synthesis inhibitors.Okay. Even though the name is a bit complicated, this medicine does something very important.

These medications are mainly used for:

• Allergies, especially Allergic Rhinitis: This is what we usually call allergies to dust mites or cats. Symptoms include a runny nose, sneezing, nasal congestion, and itchy eyes.
• Allergic Asthma: If asthma symptoms are aggravated by an allergy, this medication can help.
• Exercise-induced asthma: Some people may experience an increase in their asthma symptoms when exercising, running, or jumping. This medication is also useful in such cases.

The important thing is that these medications are not used to quickly reduce an allergic reaction or an asthma attack that has already occurred. They are used to prevent such conditions from occurring or to lessen their symptoms . It's like an umbrella, if you hold it up before it rains, you won't get wet. That's how it is.

What types of Leukotriene Modifiers are there?

There are several types of medications in this category. When your doctor prescribes one for you, it may be called one of these names:

• Montelukast - You may have heard of this under the brand name `Singulair®`.
• Zafirlukast - This comes under the brand name `Accolate®`.
• Zileuton - This is available under the brand name `Zyflo®`.

All three are used to treat asthma. However, only Montelukast is approved to treat allergic rhinitis , that is, nasal allergies.

How do these medications work? It's amazing, isn't it?

These medications work in two ways. It's like there are two solutions to a problem.

1. Montelukast and Zafirlukast belong to a group of drugs called leukotriene receptor antagonists . Imagine that there are small 'locks' in your body, and when these chemicals called leukotrienes come and fit into this lock like a 'key', that breathing difficulty occurs. What this drug does is, before this leukotriene key fits into that lock, it blocks that lock by inserting another 'dummy' key. Then those leukotrienes cannot function. That is, it stops the effect of the leukotrienes.

2. Zileuton is a little different. It belongs to a group of drugs called leukotriene synthesis inhibitors.This is what it does by making those 'troublesome' chemicals called leukotrienes inside the body, that is, reducing their production. It's like stopping the production of goods in a factory. Then the amount of leukotrienes in the body decreases.

Do you understand? In one way, it doesn't allow leukotrienes to work, and in another way, it reduces the production of leukotrienes.

How do I use this medicine? What should I be careful about?

These leukotriene modifiers usually come in the form of tablets, which means they are taken by mouth .

The most important thing is to take this medicine every day as prescribed by your doctor . It is important to take the medicine on time, whether you have difficulty breathing that day or not. Because, as we said before, these are used to prevent breathing difficulties. Just like a daily vitamin, you need to take it every day to maintain the protection it provides.

Your doctor will give you some specific instructions about this medicine:

• Dose: This means how much to take and how many times a day.
• When to take the medicine: In the morning, twice a day, or at night. This may depend on when your symptoms are most severe.
• Whether to take it with or without food: Some medications should be taken before meals, some after meals. Ask for it carefully.

Never take more or less of this medicine than your doctor has prescribed. Doing so may reduce the effectiveness of the medicine and cause unwanted side effects.

What are the benefits of using Leukotriene Modifiers?

If you use these medications correctly, you can get a lot of relief. Here are the benefits:

• Breathing becomes easier: Chest tightness and wheezing are reduced, and you can breathe more freely.
• You can exercise despite having difficulty breathing: If you have previously experienced shortness of breath while exercising, this medication will allow you to control the condition and engage in exercise.
• Helps keep airways open: We said that airways swell and become tight, so it reduces those conditions.
• Reduces mucus in the chest and throat: The mucus is reduced, making breathing easier.
• Helps prevent breathing problems, such as allergic reactions and asthma attacks.
• Reduces the number and severity of reactions and attacks.

This can make your daily life much easier.

Are there any risks with these medications?

Like any medication, these leukotriene modifiers can have some risks.

Liver damage caused by some leukotriene modifiersIt is possible. Therefore, if you already have a liver condition, you may not be able to use these medications. While you are taking this medication, your doctor may also do blood tests to check if your liver is working properly. This is for your safety.

What are the possible side effects?

Leukotriene modifiers are generally considered safe. However, some people may experience side effects. Don't worry, these are usually not serious.

Commonly seen side effects:

• Symptoms of a cold: cough, sore throat, runny nose.
• Stomach upset: Diarrhea, stomach pain.
• Ear infection.
• Fatigue: It means feeling tired.
• Flu-like symptoms: fever.
• Headache .
• Heartburn: It feels like a burning sensation in the chest.
• Itching or rash.
• The food is tasteless.
• Nausea: Feeling like vomiting.

If you experience a common side effect like this, if it doesn't go away in a few days, or if you find it difficult to tolerate, talk to your doctor.

However, sometimes more serious side effects can occur. If you notice anything like this, you should see a doctor or go to a hospital immediately:

• Changes in mental health: This is very important. If you experience depression , thoughts of suicide , or sudden aggressiveness , don't ignore it. Some people taking this medication have reported experiencing these mental effects. So, if you or someone in your family notices a big change in behavior or mood while taking this medication, tell a doctor right away.
• Blistering, peeling, or severe rashes like hives.
• Hoarseness or a sore throat.
• Heart palpitations.
• Numbness or tingling sensation in the limbs.
• Swelling of the face, eyes, mouth, or throat.
• Difficulty breathing or swallowing.
• Vomiting.
• Yellowing of the skin or eyes (Jaundice): This could be a liver problem.

If you see something serious like this, it's best to seek medical advice without wasting time.

Are there any interactions with other medications?

Yes, Leukotriene Modifiers can interact with other medications you are taking. Therefore, it is very important to tell your doctor about all the medications you are taking, including prescription medications, over-the-counter pain relievers, vitamins, and herbal remedies.

Some medications that may interact with these medications are:

• Some medications for cancer (e.g. `Alpelisib`, `dabrafenib`, `enzalutamide`).
• Some types of antibiotics (e.g. `Erythromycin`, `rifapentine`).
• Some medications for mental illness (e.g. Loxapine - a medication for schizophrenia- like conditions).
• Medications for cystic fibrosis (e.g. Lumacaftor).
• Some antihistamines (e.g. Terfenadine - a medicine used to prevent or treat allergy symptoms).
• Blood thinners (e.g. `Warfarin` - a medicine that helps prevent blood clots, strokes, and heart attacks).

This list is not complete. Therefore, be sure to discuss all medications you take with your doctor so that he or she can recommend the safest and most appropriate treatment for you.
