Problems solved by technology

[0007] Tofacitinib is a JAKs inhibitor, which reduces cytokine signal transduction, cytokine-induced gene expression and cell activation by inhibiting the JAKs pathway, thereby reducing a variety of chronic inflammatory responses. It can be used for anti-inflammatory skin wounds, but Tofacitinib The solubility of tini is small, and it is difficult to achieve the therapeutic effect. Therefore, it is necessary to increase the content of tofacitinib or to enhance its transdermal penetration effect through a transdermal enhancer. In the prior art, transdermal enhancement such as 8% dimethyl sulfoxide is added. Drugs can enhance the transdermal penetration of tofacitinib, but the skin penetration enhancer will cause skin damage, which may aggravate wound infection

Abstract

The invention relates to a preparation facilitating wound healing and a preparation method of the preparation, and belongs to the technical field of medicines. The preparation comprises siloxane substrates, JAKs (Janus kinase) inhibitors, corticosteroid, acceptable accessories in skin external preparations and water. The preparation has the advantages that the preparation facilitates scars to be healed, restrains wound infection, prevents scar formation, and the like. The JAKs inhibitors and the corticosteroid are combined, an inflammation signal pathway is restrained, proinflammatory cytokinesignal transduction is interfered, better treatment effect can be acquired, a formula of the preparation is optimized, percutaneous absorption of functional medicines in the preparation can be facilitated, moist environments of a wound and the periphery of the wound can be kept, wound secretion can be effectively absorbed, compatibility between the preparation and a human body is good, safety ishigh, the preparation can prevent bacteria from entering the wound, secondary infection is prevented, wound healing is facilitated, and scar formation is prevented. The preparation is low in cost andsuitable for scale production, and a preparation process of the preparation is simple.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a preparation for promoting wound healing and a preparation method thereof. Background technique [0002] Scar tissue refers to fibrous connective tissue in the aging stage formed by remodeling and maturation of granulation tissue. In situations such as trauma, fibroblasts divide, proliferate, migrate to the damaged site, produce extracellular matrix, and form scar tissue, thereby repairing the wound. Its formation is a process of gradual fibrosis of granulation tissue. At this time, there are more and more reticular fibers and collagen fibers, reticular fibers are collagenized, and collagen fibers become thicker. At the same time, fibroblasts are less and less, and a small amount of remaining Transform into fibroblasts; the fluid in the interstitium is gradually absorbed, and neutrophils, macrophages, lymphocytes, and plasma cells disappear successively; capillarie...
