PDE also are important in seizure incidence. PDE inhibitors have been identified as new potential therapeutics in areas such as pulmonary arterial hypertensioncoronary heart diseasedementiadepressionasthmaCOPDprotozoal infections including malaria and schizophrenia. British Journal of Clinical Pharmacology. Each of these agents is effective across a broad range of etiologies, including vasculogenic ED in men. Precautions are necessary for all 3 of the PDE5 inhibitors regarding this potential interaction. A preliminary study with sildenafil and sublingual nitroglycerin suggested the interaction is no longer observable by 4 hours. The interaction between tadalafil and nitroglycerin has dissipated by 48 hours after tadalafil administration. Molecular Pharmacology. The cyclic nucleotide phosphodiesterases comprise a group of enzymes that degrade the phosphodiester bond in the second messenger molecules cAMP and cGMP.
Currently, 3 phosphodiesterase 5 (PDE5) inhibitor agents are available worldwide for the treatment of erectile dysfunction (ED): sildenafil. Usually in these reaction the coupled step was conversion of the product of the PDE reaction (either 5′AMP or 5′GMP) to the corresponding nucleoside and. of this cyclic nucleotide.

Churchill Livingstone. Zaprinast inhibits the growth of asexual blood-stage malaria parasites P. Because PDE5 enzyme is found within the vascular smooth muscle cells in the walls of systemic arteries and veins, PDE5 inhibitors are mild vasodilators associated with small and in general, clinically insignificant decreases in blood pressure.

However, because of the synergistic decrease in blood pressure both systolic and diastolic in the presence of organic nitrates, these 3 agents are contraindicated in patients receiving organic nitrates.
Phosphodiesterase enzymes have been shown to be different in different types of cells, including normal and leukemic lymphocytes  and are often targets for pharmacological inhibition due to their unique tissue distribution, structural properties, and functional properties.

A phosphodiesterase PDE is an enzyme that breaks a phosphodiester bond. Namespaces Article Talk. PDEs are therefore important regulators of signal transduction mediated by these second messenger molecules.
