But there's no evidence that Viagra causes eye damage, even in those who take high doses, according to a new study. Since Viagra lowers blood pressure overall, there was a suspicion that the drug might decrease blood flow to optic nerves -- nerves that control vision -- which can cause nerve damage. However, this study of 13 men at Stanford University found that high doses of Viagra by and large preserved the thickness of the choroid layer of the eye, indicating that blood flow was normal. There were some small variations in thickness, which indicated that some men with an underlying blood vessel condition -- such as hardening of the arteries -- may indeed have changes in vision. The study appears in the November-December 2002 issue of Ophthalmologica. Viagra has the generic name of sildenafil citrate, and is marketed by Pfizer Inc. Viagra is prescribed for men who suffer from erectile dysfunction, commonly referred to as ED. Viagra is a phosphodiesterase type 5 (PDE-5) inhibitor, which is designed to assist men who suffer from ED, by slightly dilating the arteries in order to increase blood flow in the penis so that these men can maintain an erection when sexually aroused. Viagra received its approval in 1998, and has been widely prescribed, as it has been reportedly used by approximately 23 million men. Since the drug was introduced, it has been the subject of widespread marketing campaigns by Pfizer. Some reports estimate that sales of Viagra were approximately $1.74 billion in 2002. Common side effects of Viagra may include, headache, upset stomach, diarrhea, urinary tract infection, and flushed skin.

    Study results suggest that PDE-5 inhibitors could have a role in treating cancer, heart failure, neurodegenerative diseases, circulatory disorders and even infectious diseases, but the road to approval for new indications may not be smooth. The infamous ‘little blue pill’, Viagra (sildenafil), is one of the world’s most successful products of drug repurposing — widening a drug’s use for more than one indication. Originally developed in the 1990s by Pfizer to treat hypertension and angina, it became apparent during clinical trials that sildenafil induced penile erections, and the rest, as they say, is history. Now, basic scientific data and results from clinical studies have suggested that sildenafil and other phosphodiesterase type 5 (PDE-5) inhibitors, such as tadalafil, may have multiple applications in cancer, heart failure, neurodegenerative diseases, circulatory disorders and even infectious diseases.“In some ways, repurposing is a standard part of drug development,” says Pan Pantziarka from the Anticancer Fund, a research initiative based in Brussels. “Once [a pharmaceutical company] has a licence, they then seek to repurpose [the drug].” Pantziarka is programme director for drug repurposing and coordinator of the Repurposing Drugs in Oncology (Re DO) project ( an international collaboration between the Anticancer Fund and the not-for-profit drug development organisation Global Cures, based in Massachusetts. According to the US government trials registry, there are over 650 trials for PDE-5 inhibitors ongoing for an array of conditions. But with first-generation PDE-5 inhibitors off-patent since 2013, and limited interest from the pharmaceutical industry, there is no clear path to repurposing.
