Raman spectroscopy in combination with partial least-squares (PLS) regression method was developed for sulphamethoxazole (SMZ) and trimethoprim (TMP) simultaneous determination in powder mixtures. The calibration set was...

Propranolol-HCl (PPN-HCl) is a non selective β-adrenergic blocker widely used in therapeutics. Nevertheless, their physicochemical properties in aqueous media have not been adequately studied. In this context, by usin...

The solubility of sulfanilamide (SA) in propylene glycol + water cosolvent mixtures was determined at temperatures from 293.15 to 313.15 K. The thermodynamic functions: Gibbs energy, enthalpy, and entropy of solution and...

Green tea extracts are being widely used in food products due to their health-promoting properties. Polyphenols can interact with food proteins leading to the formation of soluble or insoluble complexes; therefore they c...

The aim of this study was to investigate the impact of solid dispersions of polyethylene glycol 6000 (PEG 6000), using the co-precipitation method, on the in vitro solubility and intestinal absorption of praziquantel (PZ...

Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were used to investigate drug-excipient interactions and, in consequence, their compatibility. For this purpose, binary mixtures of olanzapine ...

The present study utilizes approach of solid dispersions (SDs) to improve dissolution rate of Gliclazide (GLZ); a poorly water soluble anti-diabetic drug. Formulations were prepared by solvent evaporation and melt disper...

A simple, efficient and reliable capillary zone electrophoresis method with diode array detection was developed and validated for the simultaneous determination of olmesartan medoxomil and amlodipine besylate in their bi...
