Name Hydroxyproline
  • approved
  • experimental
Description Hydroxyproline is a neutral heterocyclic protein amino acid. It is found in collagen and as such it is common in many gelatin products. Hydroxyproline is mostly used as a diagnostic marker of bone turnover and liver fibrosis. Therapeutically, hydroxyproline is being studied as an an experimental medicine but is approved in France as a combination topical gel product called Cicactive for small, superficial wounds.
  • L-Hydroxyproline
  • trans-4-Hydroxy-L-proline
Brand Names
Affected Organism Humans and other mammals
Indication Used in France as a combination product for the treatment of small, superficial wounds.
Pharmacology Hydroxyproline as well as proline and glycine are the major components of collagen. Collagen is on one of the main building blocks of connective tissue such as skin, bone, and cartilage. Thus when these tissues are damaged, hydroxyproline is necessary for repair of the damaged area.
