Chlordiazepoxide, a member of the 1, 4-benzodiazepine, showing poor aqueous solubility and dissolution rate in water, so the present work was focused to prepare the microspheres of Chlordiazepoxide to improve its solubility and dissolution; using chitosan with different drug: polymer ratio by spray-drying technique. The effect of different drug: polymer ratio on the solubility and dissolution o...

Neutralizing antibodies (NA) inherently present in pooled plasma collected at commercial abattoirs may provide some protection against potential porcine circovirus type 2 (PCV2) infectivity of plasma. Moreover, these NA may also contribute to the biosafety of spray-dried porcine plasma (SDPP). The objective of the study was to characterize and quantify the PCV2 antibody neutralizing capacity in...

the first aim of the present investigation was to prepare solid dispersions to improve the dissolution properties of oxcarbazepine and quetiapine using peg 6000 as a carrier with the help of two methods of preparations viz. spray drying and modified solvent method, and to compare the two methods. the second objective was to apply the modified solvent method for preparation of sustained release ...

Metformin hydrochloride exhibits poor compressibility during compaction, often resulting in weak and unacceptable tablets with a high tendency to cap. The purpose of this study was to develop directly compressible metformin hydrochloride by the spray-drying technique in the presence of polymer. Metformin hydrochloride was dissolved in solutions containing a polymer, namely polyvinylpyrrolidone ...

Improved production methods of starter cultures, which constitute the most important element of probiotic preparations, were investigated. The aim of the presented research was to analyse changes in the viability of Lactobacillus. acidophilus and Bifidobacterium bifidum after stabilization (spray drying, liophilization, fluidization drying) and storage in refrigerated conditions for 4 months. T...

The objectives of this study were to use soybean cake as the raw material for the production of isoflavone powder and compare the effects of different carriers as well as drying methods on the powder quality. Results showed that with spray drying, a level of 40% maltodextrin as carrier produced the highest yield (mass) of isoflavone powder, followed by 10% gelatin and 1% sodium alginate. Howeve...

Cidofovir is a new class of antiviral agent with potent in vitro and in vivo activity against a broad spectrum of herpes viruses. The aim of this work was to obtain a prolonged therapeutic effect of cidofovir in the basal epidermis after its topical application. For this purpose, poly(lactide-co-glycolide) (PLGA) microparticles were prepared by solvent evaporation and spray-drying methods. Micr...
