Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A comparison of combination chemotherapy of sildenafil plus carboplatin and weekly taxol with carboplatin and weekly taxol in patients with previously untreated advanced non-small cell lung cancer. The study hypothesis is that sildenafil may improve the distribution and efficacy of cytotoxic anticancer agents.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sildenafil is one of selective phosphodiesterase type 5 inhibitors. It is used to block the degradative action of phosphodiesterase type 5 on cyclic GMP in the smooth muscle cells lining the blood vessels, which leads to smooth muscle relaxation in blood vessels and increases blood flow. Because phosphodiesterase type 5 is also present in the arterial wall smooth muscle within the lungs, phosphodiesterase type 5 inhibitors is also used for the treatment of pulmonary hypertension.
