The present invention provides a composition based on cannabidiol (CBD) and chitosan for use in reducing blood cholesterol, blood LDL and blood triglycerides levels.

The present invention provides a composition based on cannabidiol (CBD) and chitosan for use in reducing blood cholesterol, blood LDL and blood triglycerides levels.

Disclosed are antimicrobial compositions and formulations directed against a broad range of bacteria and Pseudomonas aeruginosa biofilms. In an aspect, the compositions and formulations do not engender resistance. In an aspect, in combination with antibiotics, the compositions and formulations slow the development of antibiotic-resistance and greatly improve bacterial susceptibility to multiple classes of antibiotics.

Concentrated, low-viscosity, low-volume liquid pharmaceutical formulations of polysaccharides and nucleic acids have been developed. Such formulations can be rapidly and conveniently administered by subcutaneous or intramuscular injection, rather than by lengthy intravenous infusion. These formulations include low-molecular-weight and/or high-molecular-weight polysaccharides and nucleic acids, and viscosity-lowering agents.

The present invention relates to a method for body weight control in a subject in need thereof, comprising administering an effective amount of a thiolated chitosan to the subject. In particular, the thiolated chitosan of the present invention comprises a plurality of thiol groups covalently bonded to a chitosan moiety thereof. The thiolated chitosan of the present invention can be orally administered, which is effective in slowing down body weight gain and has good biocompatibility.
