Counterfeit phosphodiesterase type 5 inhibitors pose significant safety risks
Counterfeit drugs are inherently dangerous and a growing problem; counterfeiters are becoming increasingly sophisticated. Growth of the counterfeit medication market is attributable in part to phosphodiesterase type 5 inhibitor (PDE5i) medications for erectile dysfunction (ED). Millions of counterfeit PDE5is are seized yearly and account for the bulk of all counterfeit pharmaceutical product se...
متن کاملAB030. Evolution of phosphodiesterase type 5 inhibitors
After launching of sildenafil citrate, the last invention of 20 century, in 1998, oral phosphodiesterase type 5 (PDE5) inhibitor has been established as first line treatment of erectile dysfunction and shift new paradigm of diagnosis and treatment of erectile dysfunction. The big success of sildenafil in pharmaceutical R&D induced the consecutive development of the so-called ‘The second Viagra’...
متن کاملPhosphodiesterase type 5 inhibitors for erectile dysfunction.
The cyclic nucleotide signalling pathway mediates the smooth-muscle relaxing effects of nitric oxide necessary for normal erectile function. Down-regulation of this pathway is central to the pathophysiology of many forms of erectile dysfunction (ED), which is often associated with other chronic diseases (e.g. hypertension, type 2 diabetes mellitus) and treatments (e.g. certain drugs, radical pr...
متن کاملEffects of phosphodiesterase-5 inhibitors on sperm parameters and fertilizing capacity.
The aim of this review study is to elucidate the effects that phosphodiesterase 5 (PDE5) inhibitors exert on spermatozoa motility, capacitation process and on their ability to fertilize the oocyte. Second messenger systems such as the cAMP/adenylate cyclase (AC) system and the cGMP/guanylate cyclase (GC) system appear to regulate sperm functions. Increased levels of intracytosolic cAMP result i...
متن کاملPhosphodiesterase type 5 inhibitors: back and forward from cardiac indications.
PDE5 inhibitors (PDE5i) are widely known as treatment for erectile dysfunction (ED). This favorable action has emerged as a "side effect" from pioneering studies when PDE5i have been originally proposed as treatment for coronary artery disease (CAD). PDE5i showed marginal benefits for CAD treatment; although disappointing for that indication, they improved systemic and pulmonary vasodilation an...
