“Cannabinoids show promise for the treatment of various medical conditions such as emesis, anorexia, pain, cancer, multiple sclerosis, Parkinson’s disease and glaucoma.
The objective of the present work was to assess the feasibility of developing cannabinoid loaded poly-ε-caprolactone (PCL) microparticles prepared by the oil-in-water emulsion-solvent evaporation technique as a suitable dosage form for their administration.
In vitro cell viability studies demonstrated the antitumoral activity of CBD released from microparticles. After 4 and 7 days of incubation, CBD in microspheres significantly inhibited the growth of MDA-MB-231 cells by 60% as compared to the 50% attained with free drug.
The results suggest that PCL microparticles could be an alternative delivery system for long-term cannabinoid administration, showing potential therapeutic advantages over free drug.”
