The effects of spray drying, HPMCAS grade, and compression speed on the compaction properties of…
Spray dried dispersions (SDDs) have the potential to dramatically improve the oral bioavailability of drugs with poor water solubility. However, SDDs tend to have material attributes, such as small particle size, low bulk density, and poor flowability, which are undesirable for downstream processing…

Overcoming the dissolution rate, gastrointestinal permeability and oral bioavailability of…
Simvastatin (SIM) and glimepiride (GLM) were co-formulated into nanosuspensions and self-nanoemulsifying drug delivery systems (SNEDDS) to improve their dissolution rate and oral bioavailability. Nanosuspension was prepared by liquid anti-solvent precipitation method, involving supersaturation of a…

Zero-order drug delivery: State of the art and future prospects
Pharmaceutical drugs are an important part of the global healthcare system, with some estimates suggesting over 50% of the world's population takes at least one medication per day. Most drugs are delivered as immediate-release formulations that lead to a rapid increase in systemic drug…

Acyclovir-Loaded Solid Lipid Nanoparticles: Optimization, Characterization and Evaluation of Its…
Acyclovir is an antiviral drug used for the treatment of herpes simplex virus infection. Its oral bioavailability is low; therefore, frequent and high doses are prescribed for optimum therapeutic efficacy. Moreover, the current therapeutic regimen of acyclovir is associated with unwarranted adverse…

Determining the Best Poloxamer Carrier for Thiocolchicoside Solid Dispersions
Industrial pharmacists make many attempts to enhance the solubility of drugs economically. Among the various approaches for enhancing solubility, the solid dispersion (SD) approach is gaining in importance as it is simpler and requires less effort than the other approaches.1
Thiocolchicoside…

Controlled Release of Metformin Hydrochloride for Improving the Oral Bioavailability Based on a…
This paper demonstrated that a novel enteric osmotic pump capsule (EOPC) could effectively deliver metformin hydrochloride (MH) into the small intestine and keep releasing in a sustained manner consistently. The MH EOPC was composed of enteric semipermeable capsule shell and the core prescription…
