Levitra has proved highly successful in clinical trials and is generating major interest as a real alternative to Viagra, Uprima and Cialis.
Levitra is a new oral PDE-5 inhibitor for the treatment of male erectile dysfunction (ED). Phosphodiesterase type 5 (PDE-%) is the predominate enzyme found in human penile erectile tissue and is associated with erections. PDE-5 inhibitors such as Levitra typically work by blocking this enzyme to enhance or prolong the erectile process.
Levitra is marketed by the leading pharmaceutical companies Bayer and GlaxoSmithKline, through a worldwide co-promotion and co-development agreement.
