Compositions and methods for treating or preventing diseases associated with oxidative stress

Methods and compositions for treating various indications by lessening oxidative stress in a patient are provided. A pharmaceutical composition comprises between about 0.001% to about 10.0%, or more specifically between about 0.015% to about 5%, sodium iodide or catalase by weight. The iodine ion or the catalase dissociates hydrogen peroxide into water and molecular oxygen to interrupt biological events that result in negative side effects. The pharmaceutical composition further comprises in some cases a reducing agent or various carrier materials. The pharmaceutical composition is in some cases formulated for a variety of delivery methods.

Rapid-deposition thin-film forming compositions as effective wound care treatment
11471481 · 2022-10-18 · ·

The present invention provides thin-film forming compositions comprising an antiseptic (e.g., povidone iodine, chlorhexidine, or octenidine), a non-aqueous solvent, and a film-forming material dissolved in the non-aqueous solvent, wherein the composition yields a continuous and flexible protective film upon substantial removal of the solvent. The compositions are useful for the treatment and prevention of infections in wounds, ulcers (e.g., decubitus ulcers and stasis ulcers), cuts, or burns, or against infections from bacterial, mycobacterial, viral, fungal, or amoeba causes, as well as for prevention of such infections in appropriate clinical settings (e.g., as liquid bandages or dressings). Additionally, the compositions of this invention are also useful for the treatment of infections and as a disinfectant skin preparation for pre- and/or post-surgical operations.

Readily absorbable copolymer compositions for high strength sutures having enhanced strength retention post-implantation

Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.

ANTI-MICROBIAL HYDROGEL

Hydrogels are provided that include an antimicrobial agent and a cross-linkable urethane-based polymer (CUP). Such hydrogels may be used for the controlled-release of antimicrobial agents as well as in the manufacturing of wound dressings. Wound dressings are provided that comprise a hydrogel as defined herein.

COMPOSITION AND METHODS FOR ANTIMICROBIAL ARTICLES
20230180762 · 2023-06-15 ·

A biocompatible controlled release form of complexed iodine is achieved by a complexation of polyvinyl alcohol based foam and characterized by a residual starch component to optimize iodine release profiles. The resulting iodine complexed polyvinyl alcohol foam may be utilized locally as an antimicrobial agent that releases controlled amounts of iodine sufficient to kill microbes for extended durations without excessive bulk and rigidity.
