Development of an Immediate-Release Prototype Tablet Formulation of Hydroxychloroquine Sulfate with an Interwoven Taste-Masking System.

Hydroxychloroquine sulfate (HCQS) was granted US-FDA approval in 1955 for the prevention and treatment of malaria. Since then, its uses have expanded to treat systemic lupus erythematosus and rheumatoid arthritis.  For each indication, HCQS is a crucial option for the treatment of pediatric, juvenile, adult, and elderly populations.

Preparation and characterization of fast dissolving pullulan films containing BCS class II drug nanoparticles for bioavailability enhancement.

The aim of this study is to assess pullulan as a novel steric stabilizer during the wet-stirred media milling (WSMM) of griseofulvin, a model poorly water-soluble drug, and as a film-former in the preparation of strip films via casting-drying the wet-milled drug suspensions for dissolution and bioavailability enhancement. To this end, pullulan films, with xanthan gum (XG) as thickening agent and glycerin as plasticizer, were loaded with griseofulvin nanoparticles prepared by WSMM using pullulan in combination with sodium dodecyl sulfate (SDS) as an ionic stabilizer. The effects of drug loading and milling time on the particle size and suspension stability were investigated, as well as XG concentration and casting thickness on film properties and dissolution rate.
