The study of allergenic properties and immunotoxic effects of the ready-to-use drug form of GML-1 (N-benzyl-N-methyl-1-phenylpyrrolo[1,2-a] pyrazin-3-carboxamide), compounds with high TSPO affinity and pronounced anxiolytic activity, was carried out. The study of allergenic properties and immunotoxicity of GML-1 was performed on male albino guinea pigs weighing 250-300 g and on male CBA, C57BL / 6, F1 hybrids (CBAxC57BL/6) mice. When assessing immunotoxicity, GML-1 was inject to mice per os for 14 days in doses of 2.2 mg / kg and 22 mg / kg. When studying the allergenicity, GML-1 was injected to albino guinea pigs in doses of 1 mg / kg and 10 mg / kg according to standard regimens of immunization. The results of the study of the immuno-toxicity and allergenicity of GML-1 allow us to conclude that the injection of tablet dosage form of GML-1 in the range of studied doses does not have an immunotoxic effect and allergenic properties.

The spectrophotometric method for estimation of CefpodoximeProxetil employed first derivative amplitude UV spectrophotometric method for analysis using methanol as solvent for the drug. CefpodoximeProxetil has absorbance maxima at 235nm and obeys Beer’s law in concentration range 10-50µg/ml with good linearity i.e. r2 about 0.999. The recovery studies established accuracy of the proposed method; result validated according to ICH guideline. Results were found satisfactory and reproducible. The method was successfully for evaluation of CefpodoximeProxetil in tablet dosage form without interference of common excipients.

A reversed-phase high-performance liquid chromatographic method was developed for the simultaneous determination of olmesartan medoxomil (OLME) and chlorthalidone (CHLOR) in tablet dosage form. The analysis was performed on Inertsil ODS C18 (250 x 4.6 mm, 5 μ) using KH2PO4 phosphate buffer (pH) and acetonitrile as mobile phase in the proportion of 60: 40 v/v at flow rate of 1.0 mL/min. Detection of drugs was carried out in isocratic mode using UV detector at 275 nm. The retention time of OLME and CHLOR was 13.9 ± 0.1 min. and 4.4 ± 0.5 min., respectively and the total run time was 20 min. The method was validated according to the requirements of the United States Pharmacopeia. The percentage recoveries was found to be in the range of 98.9 - 100.7%. The method was successfully applied to the assay of OLME and CHLOR in tablet dosage form.
