Which drug among the listed is NOT a cause of pulmonary fibrosis?

  1. Amiodarone

  2. Sildenafil

  3. Bleomycin

  4. Busulfan

The correct answer is: Sildenafil

Pulmonary fibrosis is a medical condition caused by scarring in the lungs. The scarring can thicken and stiffen the lung tissue, which can make it difficult for oxygen to pass through the walls of the air sacs and into the bloodstream. Amiodarone, Bleomycin, and Busulfan are all known to be potential causes of pulmonary fibrosis. However, Sildenafil is not a known cause of pulmonary fibrosis. Sildenafil is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. Therefore, it is not a correct answer for this question.
