Summary
Phenytoin,
used orally and/or topically, promotes healing. The healing properties
of oral PHT were first reported by Bodkin in 1945 in an extensive study
of pruritus ani. Subsequently, oral PHT has been reported useful in the
treatment of periodontal disease, scleroderma, epidermolysis bullosa,
peptic ulcers, and a variety of skin and soft tissue wounds and ulcers.
Topical
PHT has been demonstrated to relieve the pain and promote the healing
of chronic soft tissue ulcers, including venous stasis, diabetic and decubitus
ulcers, and also burns. Recently, PHT has been found effective in healing
the chronic trophic ulcers of leprosy.
Relief
of pain with topical PHT is prompt, usually occurring in a matter of minutes.
Biopsies
of PHT-treated ulcers show increased formation of new blood vessels and
increased collagen content. In addition, the scar tissue that forms is
more flexible in PHT-treated wounds. Extensive laboratory studies have
shown that PHT accelerates the healing and tensile strength of various
wounds and fractures, stimulates fibroblast proliferation, increases collagen
synthesis, content, and maturation in granulation tissue, and inhibits
collagenase and collagen peptidase activity.
