AB  - The chromatographic behavior of cephalexine, cefaclore, ceftriaxone, cefiuime, and cefotaxime has been investigated on silica gel layers with binary mobile phases containing different amounts of organic modifier. The influence of type, chemical character, and position of substitution of functional groups (steric and structural effects) on the retention of analyzed compounds was of particular interest. Systematic investigation of the cephalosporins furnished much information about their hydrophobicity (R-M(0)), the mechanism of adsorption, and the possibilities of separation. Correlation of the hydrophobicity parameters R-M(0), m, and C-0 with the lipophilicity parameter log P was established by use of linear equations. The parameter C-0 was considered as directly applicable in quantitative structure-activity relationships of the cephalosporins.

AB  - The proposed method for the determination of fluocortolone is based on the formation of a stable, yellow coloured hydrazone product with 1,4-dihydrazinophthalazine as the reagent. Heating at 85 °C for 2 h was found to be necessary to ensure optimal hydrazone formation in acidified 1-propanol as the solvent. The detection limit was 1.2 μg/ml. This method when applied for the determination of fluocortolone in pharmaceutical formulations gave precise and reproducible results.

AB  - The photodecomposition of nisoldipine ((+/-)3-isobutyl-5-methyl-1,4-dihydro-2,6-dimethyl-4-(2-nitrophenyl)-pyridine-3,5-dicarboxylate), whereby its 4-(2-nitrosophenyl) pyridine analogue is obtained as the photolytic product, was investigated under daylight exposure by means of UV derivative spectrophotometry. The optimal instrumental parameters (120 nm/min scan speed: 2 nm slit width; Delta lambda = 10 nm and 5 s response time) for analogue derivative spectra were established for amplitudes D-1(285) and D-2(291) (measured to the baseline) of the nitroso analogue assay, as well as for D-1(386) of the parent compound-nisoldipine assay. Using the first-order derivative spectrum, the minimum detectable amount of nitroso analogue in the presence of nisoldipine was equivalent to an impurity level of 5% and by the second-order derivative spectrum, the determination limit was equivalent to an impurity level of 2%. The degradation of nisoldipine followed within 30 days and the calculated maximal degradation rate was 1.6% per day for nisoldipine raw material, but significantly lower values of 0.19 and 0.15% per day were obtained for Nisoldin(R) tablets (10 and 5 mg, respectively).

AB  - A new diiodine substituted LDA derivative, 2,4-diiodine-6-methyl IDA (DIIODIDA) was synthesized and labeled with Tc-99m. It was established that Tc-99m-DIIODIDA had high radiochemical purity. Biodistribution and influence of bilirubin on Tc-99m-DIIODIDA biokinetics has been studied in rats and compared to the corresponding results for Tc-99m-SOLCOIODIDA. Related to Tc-99m-SOLCOIODIDA, Tc-99m-DIIODIDA has much better biliary exretion (55.18 versus 43.63%). No change of Tc-99m-DIIODIDA biokinetics, under influence of bilirubin was noticed. Biliary excretion of Tc-99m-SOLCOIODIDA has been reduced for about 60%. The protein binding of Tc-99m-DIIODIDA and Tc-99m-SOLCOIODIDA were also determined, using in vitro method of precipitation. These results showed that Tc-99m-DIIODIDA hepatobiliary imaging agent is superior to the presently used Tc-99m-monoiodine IDA derivatives.

AB  - A simple and reliable thin-layer chromatographic method for determining sulpiride and impurities of 2-aminomethyl-1-ethylpyrrolidine and methyl-5-sulphamoyl-2-methoxybenzoate was developed and validated. A methylene chloride-methanol-ammonia solution (25%; 18 + 2.8 + 0.4, v/v) solvent system is used for separation and quantitative evaluation of chromatograms. The chromatographic plate is first scanned at 240 nm to locate chromatographic zones corresponding to sulpiride and methyl-5-sulphamoyl-2-methoxybenzoate. Then 2-aminomethyl-1-ethylpyrrolidine is derivatized in situ with ninhydrin, and resulting colored spots are measured at 500 nm. The method is reproducible and convenient for quantitative analysis and purity control of sulpiride in its raw material and in its dosage forms.

AB  - A simple HPLC procedure, suitable for the determination of sodium fusidate (SF) in dosage forms, was developed. The method involves using a UV detector (208 nm) in the presence of basic buffered media (pH 7.25) under reversed-phase conditions (Supelcosil(R) LC18(TM), 3 mu m particles). The linear regression between the concentration of SF and the peak area, y = -4.4566 + 8.9238x with a coefficient of correlation r = 0.9985, was confirmed for SF in the concentration range from 25 mu g/ml to 150 mu g/ml. The detection limit of SF was 12.5 mu g/ml. The HPLC method was applied for the determination of SF in dosage forms: Stanicid(R) coated tablets, Stanicid(R) ointment and Stanicid(R) sterile gauze dressing. The concentrations and statistical parameters of sodium fusidate for all the investigated dosage forms were satisfactory and ranged from 100.41 to 105.39% (the R. S. D. ranged from 1.51 to 2.75%).

AB  - The objective of this investigation was to develop a HPTLC method for the determination of ceftriaxone, cefixime and cefotaxime, cephalosporins widely used in clinical practice, High performance TLC of cephalosporins was performed on pre-coated silica gel HPTLC plates with concentrating zone (2.5 x 10 cm) by development in mobile phase ethyl acetate-acetone-methanol-water (5:2.5:2.5:1.5 v/v/v/v). A TLC scanner set at 270 nm was used for direct evaluation of the chromatograms in reflectance/absorbance mode. The calibration curves were established as dependence of peak height (linear and polynomial regression) and peak area (polynomial regression) versus ng level (125-500 ng for all cephalosporins investigated). Relative standard deviations obtained from calibration curves was compared. Precision (RSD: 1.12-2.91% (peak height versus ng) and RSD: 1.05-2.75% (peak area versus ng)), and detection limits (ng level) was validated and found to be satisfactory. The method was found to be reproducible and convenient for quantitative analysis of ceftriaxone, cefixime and cefotaxime in their raw materials and their dosage forms.

AB  - Because of the ability of g-hydroxyquinoline sulfate (8-HQS) to irreversibly bind metals from rubber stoppers, the stability of 8-HQS in tuberculin solutions was investigated, For the determination of 8-HQS, a simple and sensitive reversed-phase HPLC method with detection at 240 nm was developed and validated. Rapid decreases in concentrations of 8-HQS were found in samples stored in original vials which were exposed to different temperatures and vial positions.

AB  - The objective of this investigation was to develop an HPTLC method for the determination of ceftriaxone, cefixime and cefotaxime, cephalosporins widely used in clinical practice. High performance thin-layer chromatography of cephalosporins was performed on pre-coated silica gel HPTLC plates with concentration zones (2.5×10cm), development with mobile phase ethylacetate-acetone-methanol-water (5:2.5:2.5:1.5 v/v). A TLC scanner (Camag, Muttenz, Switzerland) set at 270 nm was used for direct evaluation of the chromatograms in reflectance/absorbance mode. The calibration curves were established dependant of peak height (linear and polinomial regression) and peak area (polinomial regression) vs ng level (125-500 ng for all cephalosporins investigated). Coefficients of variation obtained from calibration curves were compared. Precision (c.v.: 1.12-2.91% (peak height vs ng) and c.v.: 1.05-2.75% (peak area vs ng)), and detection limits (ng level) were found to be satisfactory. The method is reproducible and convenient for quantitative analysis of ceftriaxone, cefixime and cefotaxime raw materials and their different dosage forms.

AB  - A specific and simple HPLC procedure was developed, su table for the determination of dindamycin hydrochloride monohydrate (CLHC) and clindamycin 2-dihydrogenphosphate (CLPH) in pharmaceutical formulations. Rp-HPLC analysis was performed with a LCD-Analytical Consta Metric 3000 system, equipped with a Spectro Monitor 3100 UV/VIS detector. Lincosamides assay procedures were carried out on a Supelcosil R LC-18-DB (250 × 4,6 mm, 5 μm particles) column in an acetonitrile-potassium dihydrogenphosphate buffer (0.1 M; pH 2.50) (225:775 v/v) as mobile phase. Column effluents were monitored at 206 nm for clindamycin. The calibration curves in concentration ranges from 200 to 1800 μg/ml were established for the investigated clindamycins. The HPLC method was applied for the determination of clindamycin in pharmaceutical formulations. The obtained results and statistical parameters for both the investigated clindamycins in pharmaceutical formulations, were satisfactory and ranged from 99.99% to 104.18% (R.S.D. was ranged from 0.79% to 0.99%).

AB  - Cephalexin, cefixime, ceftriaxone and cefotaxime were determined spectrophotometrically in the pure form and in pharmaceutical formulations by using ferrihydroxamate method. Reaction optimization with respect to reaction time and temperature has been investigated. Influence of the presence of ester functional group on the determination of cephalosporins as beta-lactams under conditions optimized was evaluated. Using cefotaxime sodiume as model drug with ester functional group, it was shown that proposed method gives equally acurate and precise results even ill the presence of ester functional group.

AB  - TLC and HPLC methods for the determination of the preservative, 8-hydroxyquinoline sulfate in PPD-T tuberculin solution were developed. The planar chromatography method involved separation of 8-hydroxyquinoline sulfate on a TLC plate using a butyl-acetate: formic acid :2-propanol mobile phase, detection and quantitation by densitometric scanning. The HPLC method was on a LiChrosorb RP-18 column with acetonitrile-water (65:35 v/v) mobile phase, adjusted to pH 3.05 by phosphoric acid. Linearity, reproducibility and accuracy were found to be satisfactory. Under selected conditions, the limit of detection (LOD) of both methods was similar - about 25 ng.

AB  - A sensitive and simple spectrophotometric method for the determination of fluorometholone in pharmaceutical formulations using 1,4-dihydrazinophthalazine (1,4-DHPHT; dihydralazine) as the reagent is presented. The yellow coloured dihydralazinohydrazone of fluorometholone was obtained, after heating at 85 degrees C for 2 hrs in acidified 1-propanol as a solvent. The prepared dihydralazinophthalazone shows a maximum at 380 nm with molar absorptivity of 1.91x10(4) lmol(-1)cm(-1). Beers law is obeyed up to 12 mu g/ml of fluorometholone. The method applied for the determination of fluorometholone in pharmaceutical formulations gave precise and reproducible results; recoveries were 97.43% (RSD=2.67%) and 98.25% (RSD=2.56%) for ointment and suppositories, respectively.

AB  - The proposed method is based on coloured hydrazone formation with 1,4-dihydrazinophthalazine as a reagent. Heating at 85 degrees C for 2 h was found necessary to ensure optimal hydrazone formation in the presence of hydrochloric acid. The yellow hydrazone product has an absorption maximum at 380 nm. A linear relationship between absorbance and concentration was established in the concentration range 3.19 x 10(-6)-3.19 x 10(-5) mol l(-1) (the regression equation was y = 0.013 167 3 + 0.019 025 9x; correlation coefficient r = 0.9991; n = 6). The detection limit was 1.2 mu g ml(-1) (molar absorptivity found was 1.97 x 10(4) l mol(-1) cm(-1)). The reliability of the proposed method was checked at three different concentrations; the relative standard deviation (RSD) varied from 1.03 to 2.01%. The described method applied to the determination of desoximetasone in ointment gave precise and reproducible results; the recovery was 98.55% with RSD = 2.40% (n = 10).
