Abstract:
To develop and validate liquid chromatography-tandem mass spectrometric method for the quantification of ciprofibrate from human plasma. Ciprofibrate and furosemide (IS) were extracted from human plasma using Oasis HLB 1cc 30 mg solid phase extraction cartridge. The chromatographic separation was performed on ACE C18, 50×4.6 mm, 5μ column. The mobile phase consisted of 0.001% ammonia in methanol-acetonitrile-water (70:20:10, v/v/v) was delivered at rate of 1 mL/min. Detection and quantitation were performed by a triple quadrupole equipped with electrospray ionization and multiple reaction monitoring in negative ionization mode (API 3200). The most intense [M-H]- transition for ciprofibrate at m/z 287.0→85.0 and for IS at m/z 328.9.0→204.9 were used for quantification. The developed method was successfully applied for bioequivalence study of ciprofibrate. The method was found to linear over the range of 25-30000 ng/mL (r>0.998). The lower limit of quantitation (LLOQ) was 25 ng/mL. The extraction recovery was above 90%. The accuracy was found to 101.26%-106.44%. The intra and inter-day precision expressed as % CV were 1.15% and 5.25%, respectively. The stability testing was also investigated and it was found that both drug and IS were quite stable. A simple, rapid, sensitive, accurate and precise LC-ESI/MS/MS method has been developed for the quantification of ciprofibrate from human plasma using SPE method. The method exhibited good linear response over the selected concentration range 25-30000 ng/mL. Selectivity and sensitivity were sufficient for detecting and quantifying ciprofibrate in human plasma. These features coupled with a short run time at 1.8 min compared to reported methods, facilitated a high analysis throughput, with the ability to quantify a larger number of clinical samples in a shorter time frame.

ABSTRACT
A simple, precise, accurate and reproducible spectrophotometric method has been developed for simultaneous estimation of Cefixime Trihydrate (CEF) and Linezolid (LNZ) by employing first order derivative zero crossing method in Methanol. The first order derivative absorption at 290 nm (zero cross point of CEF) was used for quantification of Linezolid and 228 nm (zero cross point of LNZ) for quantification of Cefixime Trihydrate. The linearity was established over the concentration range of 2-18 µg/ml and 7-15 µg/ml for Cefixime and Linezolid with correlation coefficient r2 0.9970 and 0.9982, respectively. The mean % recoveries were found to be in the range of 98.36 % – 99.45 % and 100.10 % – 101.66 % for Cefixime and Linezolid, respectively. The proposed method has been validated as per ICH guideline and successfully applied to the estimation of Cefixime and Linezolid in bulk and in market formulation.

ABSTRACT:
The scope and need of the present work is to develop and validate an analytical method for the analysis of an anti-diabetic drug. Literature survey reveals various UV, HPLC and LC/MS methods are available for individual estimation of the Metformin Hydrochloride and Sitagliptin Phosphate and in combination with other drugs. But, none of the reported analytical methods describe a stability indicating RP-HPLC method for the simultaneous analysis of Metformin and Sitagliptin in tablet dosage form. Hence the present works aims at developing a simple, sensitive, precise, economic and validated second order derivative UV spectroscopic method & stability indicating RP-HPLC method for the simultaneous estimation of Sitagliptin and Metformin in pharmaceutical dosage form. Incomparision with direct UV method, the second order derivative UV spectroscopic method eliminates the interference from UV-absorbing excipients. This method was found to be fast and can be used for formulation screening. HPLC is an integral analytical tool in assessing drug product stability.  HPLC methods should be able to separate, detect and quantify the various drug-related degradants that can form on storage or manufacturing, plus detect and quantify any drug-related impurities that may be introduced during synthesis. Stability studies were carried out under various stress conditions like acid hydrolysis, base hydrolysis, water hydrolysis, oxidation, photolytic degradation and under UV-light. Both the drugs Sitagliptin and metformin were degraded more in the alkaline condition.

In the present work simple and sensitive RP-HPLC method has been developed for the quantitative estimation of Baclofen in bulk drug and pharmaceutical formulations.
A rapid and sensitive RP-HPLC Method with UV detection (253 nm) for routine analysis of Baclofen in Bulk drug and Pharmaceutical formulation was developed. Chromatography was performed with mobile phase containing a mixture of Methanol: Water: Acetic Acid (100:100:0.5) withflow rate 1.0 ml/min The linearity was found to be in the range of 10-50 µg/ml with (r2=0.999) A known amount of the drug solution (80, 100 and 120 %) was added to the powder sample of the tablet formulation and subjected to the estimation of the drug for the recovery studies. There was a high recovery of Baclofen (100.03%, 100.18%, and 100.05%) Robustness of the proposed method was determined by analysis of sample by changes in different parameter like flow rate, detection and Column temperature using similar operational and environmental conditions, the tailing factor was found to be less than 2. The precision of the assay was determined in terms of intra and inter-day variation in the peak area for a set of drug solution (30 µg/ml) assayed three times on the same day and on three different days  The intra and inter day variation in  the  peak  ratio of the drug  solution  was calculated in terms of co-efficient of variation (CV) and obtained by multiplying the ratio of standard deviation to the mean with 100(CV=SD/MEAN X 100)All the parameters are compared with standard raw material of baclofen. The proposed method was validated in accordance with ICH parameters and applied for analysis of the same in marketed formulations.The proposed method was validated by determining sensitivity, accuracy, precision, robustness stability
