Pharmacodynamics (Effect)This section has been translated automatically.
Minoxidil leads to significantly increased hair growth. Proven are:
- Stimulation effects on epidermal and follicular keratinocytes
- Prostaglandin PGH2 Increase
- Increase of VEGF.
Minoxidil belongs to the KATP channel openers just like diazoxide. Minoxidil binds intracellularly to the SHR unit of the potassium channel. The promotion of hair growth is probably also a consequence of the opening of the CATP channels at the hair roots.
