A process forms an implantable product including poly(glycerol sebacate) urethane (PGSU) loaded with an active pharmaceutical ingredient (API). The process includes homogeneously mixing a flowable poly(glycerol sebacate) (PGS) resin with the API and a catalyst to form a resin blend. The process also includes homogeneously combining the resin blend with an isocyanate to form a reaction mixture and injecting the reaction mixture to form the PGSU loaded with the API. An implantable product includes a PGSU loaded with an API. In some embodiments, the implantable product includes at least 40% w/w of the API, and the implantable product releases the API by surface degradation of the PGSU at a predetermined release rate for at least three months under physiological conditions. In some embodiments, the PGSU is formed from a PGS reacted with an isocyanate at an isocyanate-to-hydroxyl stoichiometric (crosslinking) ratio in the range of 1:0.25 to 1:1.25.

Tunable, controlled-release, urethane-containing elastomers and processes of forming the same

A method of forming a skin care product includes combining at least one additive including at least one active ingredient with at least one glycerol-sebacate component having repeating units of (glycerol sebacate), water, a co-solvent, and at least one of an emulsifier, a surfactant, and a bodying agent to form the skin care product. A dermocosmetic composition includes at least one additive including at least one active ingredient and at least one glycerol-sebacate component having repeating units of (glycerol sebacate). A method of skin care includes applying a dermocosmetic composition to a skin surface.

Dermocosmetic compositions including glycerol-sebacate

A method of preparing a polymeric material includes combining a glycerol-pharmaceutical conjugate, glycerol, and water in a vessel. The glycerol-pharmaceutical conjugate includes a pharmaceutical compound, for example, salicylic acid, having at least one carboxyl group attached to glycerol by an ester bond. The method also includes adding sebacic acid to the vessel and removing water from the vessel and reacting the glycerol, glycerol-pharmaceutical conjugate, and sebacic acid in the vessel at atmospheric pressure in the presence of an inert gas. The method further includes applying a sub-atmospheric pressure to the vessel after the step of reacting, to form the polymeric material in the vessel. The polymeric material includes a polyester copolymer of the sebacic acid and the glycerol and the pharmaceutical compound.

Poly(glycerol sebacate)-interleukin inhibitor copolymers and methods of making and use

The application is directed to aqueous dispersible biodegradable compositions of esters which are the condensation reaction product of a polyol and a diacid which are within a matrix of hydrated polypeptide. The compositions are useful in additive manufacturing and other applications for use with implantable articles. In some embodiments, the ester in the compositions is the product of a glyercol-sebacic acid condensation reaction.

Composition, methods and devices useful for manufacturing of implantable articles

A filler material of a thermoset resin of a diacid/polyol, such as PGS is provided. The filler useful in forming composites, such as those in which the filler and a resin matrix are of the same material to provide a homogenous polymeric composition. Composites in which at least one of the matrix, the filler or both are PGS are also provided. Methods of forming such filler materials and composites are also disclosed. The composites allow extrusion process to form articles from materials that would not otherwise be capable of being extruded.
