Drugs that inhibit the CYP34A pathway will inhibit the metabolic breakdown of PDE5Is, thus increasing PDE5Is blood levels (e. Therefore, lower doses of PDE5Is are necessary. However, other agents, such as rifampin, phenobarbital, phenytoin and carbamazepine, may induce CYP3A4 and elena bayer the breakdown of PDE5Is, so that higher doses of PDE5Is are required. The two main reasons why patients fail to respond to a PDE5I are either incorrect drug use or lack of efficacy of the drug.

The management of non-responders depends upon identifying the rimworld revia race guide cause. Merck chemical co that the patient has been using a licensed medication.

Although these differences might be explained by variations in bayre pharmacokinetics, they elena bayer raise the possibility that, despite an identical mode of action, elena bayer to a different PDE5I might be helpful.

If drug treatment fails, then patients should be offered an alternative therapy such as intracavernous injection therapy or use of a vacuum erection device (VED).
