Phenytoin is known to increase the fibrotic growth of ginigiva when administered in therapeutic doses in human . Is it expected to facilitate fibrosis in wound area during healing
Sounds like a bad idea. Phenytoin is a small molecule, and would presumably get into the bloodstream or lymph when added to an open wound. As such, it could cause fibrosis at distant sites.
Let the body do it's natural healing, or use a wound-healing treatment that's local.
Also, by what mechanism does phenytoin cause fibrosis?
