Numerous clinical trials evaluate sildenafil citrate across Early Phase 1 through Phase 4 studies sponsored by academic medical centers, pharmaceutical entities, and government agencies such as the United States Department of Defense. Beyond erectile dysfunction, investigations explore conditions including pulmonary arterial hypertension, immersion and swimming-induced pulmonary edema, mild pre-eclampsia, fetal growth restriction, traumatic brain injury, congestive heart failure, and post-surgical pulmonary hypertension. Spanning Phase 2 through Phase 4 designs, these registered trials currently hold completed, recruiting, terminated, or withdrawn statuses.
