On the basis of data of comparative clinical studies the advantages of topical drugs based on octenidine dihydrochloride in combination with phenoxyethanol are presented. The advantages of octenidine dihydrochloride/ phenoxyethanol as a local antiseptic for treatment and prevention of wound infections in case of wound defects, burns are described.

Abstract Three methods are presented for the determination of trimetazidine dihydrochloride in the presence of its acid-induced degradation products. The first method was based on measurement of first-derivative D1 value of trimetazidine dihydrochloride at 282 nm over a concentration range of 8.00–56.00 μg/mL with mean percentage accuracy of 99.80 ± 1.17. The second method was based on first derivative of the ratio spectra DD1 at 282 nm over the same concentration range with the percentage accuracy of 99.14 ± 0.68. The third method was based on separation of trimetazidine dihydrochloride from

Pyridorin®, a naturally occurring metabolite of vitamin B6 that inhibits and scavenges reactive oxygen species, is being developed as a potential therapeutic for acute kidney injury. An investigational new drug application (IND) was opened for Pyridorin in support of its ongoing oral drug clinical development program. Currently, a Pyridorin intravenous (IV) formulation is being developed for use in surgical patients. To support the IND for Pyridorin, a full battery of nonclinical Good Laboratory Practice compliant studies was performed with no neurological or behavioral signs of toxicity seen

Complexes of antiseptic octenidine dihydrochloride with biopolymer pectin were derived. The efficiency of octenidine integretion and its ratio as the component were evaluated. The electrostatic type of complexing was confirmed by dynamic light scattering and IR spectroscopy. In vitro experiments revealed antibacterial effect of complexes of octenidine dihydrochloride and pectin polysaccharide on test culture Bacillus sp. BIM B-210, whereas growth inhibition of bacteria Staphylococcus sp. BIM B-798G, Pseudomonas aeruginosa BIM B-153, Escherichia coli BIM B-378 was not observed.
