Viagra, used by millions of men to treat erectile dysfunction, loses its patent in the UK on June 21, meaning rival manufacturers will legally be able to produce the little blue pill under its generic name, sildenafil.
Use of Viagra in the UK is on the up, with the number of British men prescribed the drug rising to a record high of 2.3m last year, from 1.8m in 2007.
Currently a fifth of prescriptions for the drug are issued privately because the NHS has put strict limits on its use at the taxpayer's expense. Pfizer's loss of the patent will mean that the NHS, which spent £40.3m on the drug last year, will make big savings, Generic makers of the drug are expected to slash the price of a pill from £10 to as little as 85p.
Viagra was Pfizer's sixth best selling drug last year, generating $2.05bn (£1.35bn) in global revenues, up 4pc on 2011. The company will launch its own cut-price version - Sildenafil Pfizer - in a bid to retain its market share.
Sales of Pfizer's highly profitable drug Lipitor, used to tackle high cholesterol, plummeted to $3.95bn last year from $9.6bn in 2011 after the drug lost its patent protection in November 2011.
