allium cepa + heparin + allantoin

allium cepa + heparin + allantoin is a topical combination drug primarily marketed under the brand name Contractubex for the treatment of various types of scars. The formulation combines the anti-inflammatory and anti-proliferative properties of Allium cepa (onion extract), which inhibits fibroblast activity and collagen synthesis, with the anti-thrombotic and anti-inflammatory effects of heparin, which helps soften the collagen structure. Allantoin provides a keratolytic effect that promotes wound healing and enhances the skin's ability to bind water, which improves the penetration of the other active ingredients and relieves itching. This synergistic combination is indicated for hypertrophic scars, keloids, and movement-restricting scars resulting from surgery, burns, or trauma.
