Abstract
As part of the development of the composition and technology of the lyophilized dosage form with the pharmaceutical substance (FS) GK-2, which possesses neuroprotective activity, model compositions and technological properties are studied with different temperature regimes of production. In connection with the peptide structure and low stability of the FS, the use of excipients stabilizing dosage form during the lyophilization cycle (cryoprotectants and lyoprotectors) was suggested. In this study, we selected the ratios of cryo- and lyoprotectors when using mannitol or sorbitol as a cryoprotectant, and as a lyоprotector for sucrose. Model compositions with different exipients ratios were studied by optical microscopy in polarized light to demonstrate the physical state of mannitol at different ratios of explosives. Using the Harrington generalized desirability function, the most optimal composition is chosen, which meets the requirements of SF XIII and has the most acceptable technological characteristics and optimal technological process.

Abstract
Solubility is the most important quality indicator, reflecting the physicochemical properties of active pharmaceutical ingredients (APIs). Prior to the release of API, solubility is one of the key factors affecting the efficacy and safety of drugs. Therefore, the directed development of new drugs with predetermined properties (drug design) should be basedon solubility of candidate substances and be taken into account when evaluating the bioequivalence of generic drugs branded, including in vitro - in vivo correlation. Given that the pharmacopeia regulation of the test for the solubility of API is reduced to a visual estimate and approximate solubility, we developed a kinetic dissolution evaluation method by laser diffraction and performed statistical analysis of the results obtained under repeatability conditions.

Abstract
The problem was considered to determine bacterial endotoxins in human albumin drugs. To improve the safety of medicines the option of dual control was recommended, which includes the rabbit pyrogen test and determining bacterial endotoxins by the LAL-test. The causes described justify the need for dual control of albumin drugs on the content of the pyrogens/bacterial endotoxins, the main of which is the special nature of the albumin molecule reversibly binding a large number of compounds, including endotoxins. There were given known causes of false-positive and false-negative reactions of the LAL-test, and sample preparation variant including dilution, temperature treatment and the use of special dispersing agents.

Abstract
Employees of the department of pharmaceutical chemistry and phar-maceutical technology received modified forms of terpene-indole alkaloids (TIA) - vincristine (VCR) and vinblastine (VBL) known in the therapy of oncological diseases by incorporating them into erythrocyte carriers (EN). This method of modification allows solving simultaneously the problems of directional transport of effective antitumor drugs and reducing the frequency and strength of side effects, and, consequently, increasing the patient's compliance to the prescribed treatment. In this paper, stability and shelf life studies of encapsulated TIAs in EN have been carried out. It was found that keeping TIA encapsulated erythrocyte form at +4 °С for 7 days is the optimal condition for storage of TIA preparations without significant reduction of the therapeutic dose (not less than 95% of the encapsulated amount).

Abstract
Studying the susceptibility of dermatophyte strains to naftifine revealed that the range of inhibitory concentrations (MIC) is 0,1-0,2 μg/ml. The naftifine spectrum is very wide and includes almost all mycotic pathogens. Testing the strains of Trichophyton rubrum, Trichophyton mentagrophytes, Microsporum canis and Epidermophyton floccosum in comparison with clotrimazole and 4-imidazole antimycotics has shown that naftifine is the most active drug affecting dermatophytes. In concentrations of no more than 1,0 μg/ml, naftifine inhibited 98,75% of dermatophyte strains. Naftifine hydrochloride can find a worthy use in the treatment of skin diseases against the background of infectious and inflammatory processes associated with mycoses.
