Abstract Phosphodiesterase 5 PDE5 has been identified in many species. Introduction First purified from rat lung, phosphodiesterase 5 PDE5 has now been identified in many species and in a wide variety of tissues Table 1.

PDE5 is an enzyme in the walls of blood vessels. It affects blood flow and how cells signal within the body. This inhibition relaxes the blood vessels and increases blood flow. In people with erectile dysfunction, PDE5 inhibitors increase blood flow to the penis, improving erectile function.

In people with pulmonary hypertension, PDE5 inhibitors can help by:. Research also suggests that PDE5 inhibitors may be helpful in treating heart disease, diabetes, and cancer. Current research is looking into whether PDE5 inhibitors are also effective in treating cognitive disorders, such as dementia. Various PDE5 inhibitor drugs are available, and people will usually take them in tablet form. Other PDE5 inhibitors include :. Read more about the best pills for erectile dysfunction here.

People who are taking nitrate medication should avoid taking PDE5 inhibitors. The combination of both medications can cause a severe decrease in blood pressure, which can potentially be fatal.

People may be taking nitrate medications for chest or heart issues. These drugs include :. PDE5 inhibitors can also potentially be harmful to people with certain conditions.

Inhibition of PDE5 that results in sustained increases in [cGMP] i are required to modify the process of apoptosis and mitotic arrest in those carcinoma cells with enhanced PDE5 expressions. Increases in PDE5 are also involved in contributing to the pathological changes in the pulmonary system resulting in hyper-proliferative remodeling of both smooth muscle and endothelium in models of pulmonary hypertension.

For this reason, the use of PDE5 inhibitors in the treatment of human pulmonary hypertension has met with some success. Side effects are generally reversible and tend to diminish during continued treatment. Differences in pharmacokinetic properties among the PDE5 inhibitors include the fact that sildenafil and vardenafil have a shorter duration of action approximately 4 h compared with the longer period of responsiveness observed with tadalafil up to 36 h.
