Which medication requires a limited distribution program directly from the manufacturer for pulmonary artery hypertension?

1. Sildenafil

2. Eplerenone

3. Bosentan

4. Ambrisentan

The correct answer is: Bosentan

Bosentan requires a limited distribution program directly from the manufacturer for pulmonary artery hypertension. This means that the medication can only be obtained through a specific program, such as a patient assistance program, rather than being available at regular pharmacies. This is typically due to the safety and effectiveness of the medication, as well as the potential for misuse. Option A, Sildenafil, is a medication commonly used for erectile dysfunction and is not typically restricted in distribution. Option B, Eplerenone, is medication used for high blood pressure and is not indicated for pulmonary artery hypertension. Similarly, option D, Ambrisentan, is also used for treating high blood pressure and has not been approved for use in pulmonary artery hypertension. Therefore, options B and D are incorrect as they are not indicated for this particular condition and do not require a limited distribution program.
