Phosphodiesterase inhibitors
Phosphodiesterase inhibitors (PDE inhibitors) are medicines that inhibit enzymes from the group of phosphodiesterases .
Either all enzymes of this group can be inhibited non-selectively or a specific enzyme can be inhibited selectively .
- Non-selective phosphodiesterase inhibitors (PDE inhibitors): methylxanthines such as caffeine , theophylline , theobromine , which non-specifically inhibit various phosphodiesterases. Theophylline is used to treat chronic lung diseases, particularly chronic obstructive pulmonary disease . Another non-specific PDE inhibitors is for the treatment of coronary heart disease used Trapidil .
- Selective phosphodiesterase inhibitors
- PDE-3 inhibitors in acute heart failure
- PDE-4 inhibitors for chronic lung diseases and plaque psoriasis / psoriatic arthritis
- PDE-5 inhibitors for erectile dysfunction and pulmonary hypertension
According to a recent review, PDE inhibitors - especially PDE-2 inhibitors and PDE-9 inhibitors - are promising agents for improving cognition . The aim here is to develop PDE inhibitors that have few side effects.
