Entity of the month

3 March 2010, Sildenafil citrate

Few chemical compounds are better known to the general public than sildenafil citrate (CHEBI:58987), traded under the name of "Viagra".The compound was first synthesised by chemists working at Pfizer, with a view to using it for the treatment of hypertension and angina pectoris. Whilst having been found to be ineffective against angina in clinical trials, it has been observed to induce penile erections and was therefore marketed by Pfizer as a drug for the treatment of erectile dysfunction.
