The four major PDE5 inhibitors are sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Stendra).

The most commonly reported AEs for oral PDE5 inhibitors are headache, flushing, dyspepsia, dizziness, and rhinitis.

Contraindications: Any concurrent use of organic nitrates, including sublingual nitroglycerin, amyl nitrite, and isosorbide mononitrate or dinitrate, is contraindicated. Nitroglycerin must be withheld at least 24 hours following the last dose of sildenafil or vardenafil, 48 hours following that of tadalafil, and 12 hours following that of avanafil, owing to the drugs’variable half-lives.21-26

Precautions: All PDE5 inhibitors have precautions in the following cardiovascular categories: 1) myocardial infarction, stroke, or life-threatening arrhythmia in the last 6 months; 2) resting hypotension (blood pressure [BP] <90/50 mmHg) or hypertension (BP >170/100 mmHg); and 3) unstable angina or angina during sexual intercourse or congestive heart failure categorized as New York Heart Association Class IV.21-26

Antihypertensive Coadministration: Alpha-blockers are a significant concern—to varying degrees—among the PDE5 inhibitors; dosing recommendations differ based on alpha-blocker use. This is especially significant given the increased occurrence of benign prostatic hyperplasia. All PDE5 inhibitors administered concomitantly with antihypertensives or alcohol use may lower BP and therefore should be used with caution.

Neurogenic ED can be caused by your nerve signaling the corpora cavernosa, where the erectile tissue is located. Neurogenic ED can be secondary to spinal cord injury, multiple sclerosis, Parkinson disease, lumbar disc disease, traumatic brain injury, and radical pelvic surgery just to name a few.  Some medications also cause erectile dysfunction.  Some of those meds include blood pressure medications, digoxin which is used to treat atrial fibrillation, anti-androgens, and antagonists which are used to treat prostate cancer. Antidepressants and antipsychotic medications.  H2 blockers which are used to treat ulcers and opiates that are used to treat pain.
