Sildenafilo: qué es, cómo funciona y qué dice la evidencia

Sildenafil: what it is, how it works and what the evidence says

For almost three decades sildenafil has been the best-known drug for erectile dysfunction, and also one of the most misunderstood.

Sildenafil vs tadalafil: what really sets them apart

Both are PDE5 inhibitors and both need sexual stimulation to work.
