Type 5 phosphodiesterase inhibition: the focus shifts to the heart.
Of the molecules that transmit an extracellular message to alter cardiomyocyte physiology, the cyclic nucleotides are among the better understood as regulators of cell function. The relatively recent identification of nitric oxide (NO) as a stimulus of cGMP production by soluble guanyl cyclase,1 as well as of the natriuretic peptides as a stimulating membrane-bound guanylate cyclase,2 has led t...
متن کاملEffect of regular phosphodiesterase type 5 inhibition in hypertension.
There are no published controlled clinical trials of regular phosphodiesterase type 5 inhibitor therapy as a long-term treatment of hypertension. In a randomized, double-blind, 2-way crossover study, 25 otherwise untreated hypertensive subjects were administered 50 mg of sildenafil or matched placebo 3 times daily for 16 days, and the effects on ambulatory blood pressure (BP), clinic BP, arteri...
متن کاملPhosphodiesterase 5 Inhibition to Treat Essential Hypertension
Treatment of hypertension is a challenging task in cardiovascular medicine. The obviously simple concept that blood pressure (BP) must be “normalized” faces the intrinsic difficulty to decrease BP values, because the effectiveness of available drug classes in terms of BP reduction is in many cases not adequate to reach the therapeutic targets.1 One possible means of overcoming this limitation i...
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...
