The invention relates to methods and compositions for improving wound healing and in particular for preventing scar formation and thus loss of function that can occur in injured tissues during the natural wound healing process. Particularly, although by no means exclusively, the invention relates to the healing of chronic wounds such as diabetic ulcers.

A composition comprises: a base oil; an additive comprising a copolymer comprising hydrophobic and hydrophilic units; and a drug. The copolymer may for example have a comb structure in which the hydrophobic units and hydrophilic units are pendant chains on a backbone of the copolymer. The hydrophobic units and hydrophilic units may for example comprise polydimethylsiloxane moieties and ethylene glycol residues respectively. The composition may for example be used as a tamponade or as a component for a tamponade administered to the eye. The invention is useful for solubilising and/or releasing drugs.

Provided herein are compositions comprising an oil-in-water emulsion, wherein the emulsion comprises a liquid oil component; a cross-linked homopolymer based on acrylic acid and/or a cross-linked copolymer of acrylic acid and acrylic acid esters; and water. In some embodiments, the composition is a vehicle for the delivery of an active agent.

Provided herein is a topical combination composition comprising tapinarof, a PDE4 inhibitor and optionally at least one additional active agent selected from a retinoid, benzoyl peroxide (BPO), a Janus kinase inhibitor (JAK inhibitor), a corticosteroid of potency class 1-4, an acaricide and combinations thereof. The active agents in the composition of this invention are in encapsulated or non-encapsulated form, according to need. The above compositions are useful for the treatment, prevention or alleviation of a skin disorder selected from psoriasis, dermatitis, acne, rosacea, ichthyosis, scaling skin, imbalance of skin barrier and tinea and exhibit synergistic and/or additive effects allowing to reduce the active agents amounts in the combination compositions.
