Development And Assessment of Ointment Formulation for Enhancing the Wound Healing Activity in Diabetic Animal

Diabetes mellitus, a chronic metabolic condition characterized by persistent hyperglycemia that poses significant clinical and socioeconomic challenges, frequently results in ulcers, infections, and even amputations. Diabetes severely impairs normal wound healing, which goes through the phases of hemostasis, inflammation, proliferation, and remodeling, due to oxidative stress, vascular insufficiency, neuropathy, and decreased angiogenesis. Together, these factors hinder the formation of granulation tissue, postpone epithelialization, and make people more vulnerable to infections. Alternative approaches are taken into consideration when conventional therapy fails. Ointment compositions have demonstrated potential as topical therapies because they can enhance the penetration of active ingredients, extend the release of medication, and preserve a moist wound environment that promotes healing. In diabetic wound models, herbal-based ointments including extracts from plants like Centella asiatica, Curcuma longa, and Aloe vera, as well as formulations employing nanocarrier systems like silver nanoparticles, have demonstrated increased fibroblast proliferation, collagen synthesis, and angiogenesis. Effective ointment formulations require the steady addition of active chemicals like growth factors, antimicrobials, or nanocarriers, as well as the selection of suitable bases, such as water-removable for better patient compliance or oleaginous for optimum occlusivity. Preclinical evaluations in rats with streptozotocin-induced diabetes often measure hydroxyproline concentration, wound contraction rate, and epithelialization time to assess therapy efficacy. Taken together, modern ointment formulations, like hydrogel-ointment hybrids and nano-herbal formulations, offer a possible strategy to speed up the healing of diabetic wounds and reduce associated issues.
