Is Ambrisentan (安立生坦) Available in China? Key Facts for Patients

For patients with pulmonary arterial hypertension (PAH), finding effective treatments is crucial. Ambrisentan (安立生坦), a medication known for its ability to lower pulmonary artery pressure and improve exercise capacity, has been used internationally since 2007. But is it available in China? This article explores its current status, mechanism of action, and what patients can expect.

Understanding Ambrisentan (安立生坦)

Ambrisentan is an endothelin receptor antagonist (ERA) that selectively blocks endothelin-1, a substance that narrows blood vessels. By relaxing pulmonary arteries, it reduces pressure in the lungs, easing symptoms like shortness of breath and fatigue. It is primarily prescribed for:

• Idiopathic pulmonary arterial hypertension (IPAH)

• PAH associated with connective tissue disease

Clinical studies show that Ambrisentan can improve patients' quality of life and delay disease progression.

Is Ambrisentan Approved in China?

Yes, Ambrisentan (安立生坦) was approved in China on May 8, 2021, making it accessible to local patients. Before this, many relied on imported versions or alternative treatments. Its approval followed rigorous clinical trials to confirm safety and efficacy under China’s regulatory standards.

Pricing and Accessibility

While the drug is now available, cost remains a concern. PAH treatments are often expensive, and Ambrisentan is no exception. Factors affecting pricing include:

• Manufacturer pricing policies

• Insurance coverage (some regional health plans may partially reimburse costs)

• Generic alternatives (if available)

Patients are advised to consult their doctors or pharmacists for the latest pricing and possible financial assistance programs.

How Does Ambrisentan Compare to Other PAH Treatments?

Other common PAH medications include:

• Bosentan (波生坦) – Another ERA, but with a higher risk of liver toxicity.

• Sildenafil (西地那非) – A phosphodiesterase-5 (PDE5) inhibitor that improves blood flow.

• Selexipag (司来帕格) – A prostacyclin receptor agonist that helps dilate arteries.

Ambrisentan is often preferred for its once-daily dosing and lower risk of liver complications compared to Bosentan. However, the best treatment varies by individual, so a specialist should guide the choice.

Patient Concerns: What You Should Know

1. Side Effects

Common side effects include:

• Swelling in the ankles or legs (peripheral edema)

• Nasal congestion

• Headaches

• Potential liver enzyme changes (monitoring is required)

2. Pregnancy Warning

Ambrisentan is not safe during pregnancy due to the risk of birth defects. Women of childbearing age must use reliable contraception while taking it.

3. Availability in Hospitals

While approved, not all hospitals may stock Ambrisentan immediately. Larger specialty centers are more likely to have it. Patients may need to check with pulmonary hypertension clinics.
