What are phosphodiesterase inhibitors?

phosphodiesterase inhibitors block one or more subtypes of phosphodiesterase enzymes that regulate intracellular levels of cyclic adenosine monophosphate (CAMP) and cyclic guanosine monophosphate (CGMP). These Messenger chemicals communicate with the cell surface signals in a cell that controls the effects of hormones and neurotransmitters that are responsible for cell function. Medicines that inhibit phosphodiesterase, interfere with phosphodiesterase 3, 4 or 5 enzymes, also known as PDE3, PDE4 and PDE5. Inhibitors of phosphodiesterase act as drugs against repelanes, anti -inflammatory substances and vasodilators. Doctors may prescribe civacozole, which prevents the adhesion of the inhibitions from inhibiting an intracellular camp and by increasing the level of this chemical messenger, in patients with diagnosed intermittent claudicatin. Drugs also produce some vasodilation or dilation of blood vessels. Patients with a diagnosis of congestive heart failure may receive short -term intravenous therapy with Milrinone thatIt affects the heart and smooth muscle. Medicines improve the ability of the left ventricle to download and also release vascular tissue, which reduces tension in the heart.

doctors could prescribe inhibitors of phosphodiesterase roflumilast or theophylline as a treatment of chronic obstructive pulmonary diseases (COPD) asthma, chronic bronchitis or emphysema. Roflumilast inhibits PDE4, which increases cellular camp and prevents inflammatory processes produced by granulated white blood cells. Patients usually use this medicine daily to prevent acute inflammatory attacks. Theophylin inhibits PDE3 and PDE4 enzymes and creates anti -inflammatory and bronchodilation effects. The thickness also increases the strength of the diaphragm muscles to allow increased inflow of calcium ions.

Papaverine and Sildenafil are fophodiesterase inhibitors that counteract the subtype of the PDE5 enzyme, which increases CGMP cellular levels. Healthcare providers may have these medicines overDensat for erectile dysfunction or as a treatment of heart, brain and peripheral or pulmonary arterial hypertension. Drugs generally reduce systemic arterial spasticity and cause vasodilation. This class of drugs also releases heart muscles by disrupting the wires. Patients can take paverin orally, intramuscularly or intravenously, while sildenafil is only orally administered.

Each group of phosphodiesterase inhibitors has the potential to cause a number of side effects. PDE3 effective drugs can cause headaches, nausea and low blood pressure and come with an increased risk of dangerous ventricular dysrythmia.
