Description
Tracleer (Bosentan) works as an endothelin receptor antagonist (ERA), which means it blocks the effects of endothelin, a substance that constricts blood vessels and elevates blood pressure in the lungs. This medication treats pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries that supply the lungs. Tracleer may help support patients' ability to exercise and prevent the condition from worsening over time. By doing so, Tracleer can help manage symptoms and improve the quality of life for individuals living with PAH.

Always follow a healthcare provider’s instructions for taking Tracleer.
Ingredients
The active ingredient in Tracleer is Bosentan. It may also contain inactive ingredients, such as corn starch, ethylcellulose, glyceryl behenate, and hydroxypropylmethylcellulose.
Contraindications
If patients fall under any of the categories listed below, they should not take Tracleer:
- Pregnancy: Bosentan can cause harm to an unborn baby and must not be used during pregnancy
- Use with Cyclosporine A: Concurrent use can lead to increased levels of bosentan and potential toxicity
- Use with Glyburide: Can lead to an increased risk of liver injury and is not recommended
- Hypersensitivity to Bosentan: Patients with a known allergy to bosentan or any of its components should avoid this medication
Cautions
- It’s important to discuss the following with a healthcare provider before starting treatment:
- Any medications you take
- Other medical conditions you have
- Whether you have any allergies
- Whether you’re pregnant or breastfeeding
- Tracleer may cause fluid retention in some patients, which might require medical intervention. Monitoring for signs of fluid retention, such as swelling in the ankles or feet and sudden weight gain, is important.
- If you experience symptoms of pulmonary edema, such as shortness of breath or difficulty breathing, it could be a sign of pulmonary veno-occlusive disease (PVOD), a rare but serious lung disease. In such cases, discontinuation of Tracleer should be considered.
- Decreased sperm counts have been observed in patients taking Tracleer. This could be an important consideration for men looking to father children.
- Tracleer can lead to decreases in hemoglobin and hematocrit levels. It’s recommended to monitor hemoglobin levels after the first and third months of treatment, and then every three months thereafter.
Side Effects
Tracleer may cause side effects. The most common ones include respiratory tract infections, headaches, fainting, flushing, low blood pressure, sinusitis, joint pain, and irregular heartbeats. Serious side effects of Tracleer may include fluid retention, leading to ankle and leg swelling. Men may experience lower sperm counts, potentially affecting fertility. Anemia is another serious side effect, characterized by low red blood cell levels. Patients should inform their healthcare provider about any significant swelling, breathing difficulties, or concerns about fertility. Regular blood tests to monitor red blood cells are recommended during treatment. Prompt medical attention is recommended for severe symptoms.
