An attempt has been made to develop a simple, sensitive and rapid high performance liquid chromatographic (HPLC) method of analysis for lomefloxacin as in pharmaceutical dosage form using 0.025 M phosphoric acid and acetonitrile (80:20) as mobile phases. The mobile phase was used as solvents to dissolve lomefloxacin and 0.0122 mg/mL stock solution was prepared. Lomefloxacin solution was scanned with UV-spectrophotometer and the absorption maximum (λmax) was found to be 287 nm. This method was successfully applied to five eye drop dosage forms of lomefloxacin encoded as pp1, pp2, pp3, pp4 and pp5 marketed by five different pharmaceutical companies and the result was found to be satisfactory and reproducible. The method was validated by spiked recovery experiments and shown to be linear for lomefloxacin. The method can be used for routine analysis in both research laboratories, and pharmaceutical and chemical industries to analyze the drugs and chemicals without any interference by the excipients.   Key words: Lomefloxacin; HPLC; Analysis; Reproducible.

Objective: A reverse-phase high-performance liquid chromatographic (RP-HPLC) method was developed and validated for the simultaneous estimation of amlodipine besylate (AD) and valsartan (VAL) in pharmaceutical dosage form, and rosuvastatin (RV) and VAL from the bulk mixture. Method: Chromatographic separation was performed on RP-C18 column. The optimized unique mobile phase (acetonitrile:water and pH adjusted to 4.8 with acetic acid) was pumped at a flow rate of 0.8 ml/min in the ratio of 75:25% v/v, and the eluents were monitored at 245 nm. Results: The assay was performed with tablet and percentage of assay was found to 101.39 for AD and 100.05 for VAL, respectively, and with bulk mixture, percentage of assay was found to 99.58 for RV and 100.32 for VAL, respectively. Linearity was obtained in the concentration range of 1–12 μg/ml for AD, 5–50 μg/mL for VAL, and 2–20 μg/ml for RV. The method was statistically validated and RSD was found to be <2%, indicating high degree of accuracy and precision of the proposed RP-HPLC method. Conclusions: The method suggests usefulness of unique mobile phase during the estimation of two or more multicomponent dosage forms. Due to its simplicity, rapidness, high precision, and accuracy, the proposed RP-HPLC method can be applied for simultaneous determination of AD and VAL in pharmaceutical dosage form, and RV and VAL in bulk mixture.

Aims: The studied drug is lacking the presence of chromophore so a reaction with NBD-Cl is optimized to facilitate its chromatographic detection, so the main aim of the work is to quantify pamidronate in a sensitive and accurate way either in bulk or dosage forms. Methodology: The quantification of this group of drugs is a challenging task as they lack the presence of chromophore groups in their structure. The proposed method depends on the chromatographic quantification of the studied drug after its derivatization via its reaction with 4-Chloro-7-nitro-2,1,3-benzoxazole and the product is separated on ODS C18 column (5 µm, 15 cm x 5 mm, i.d.) as a stationary phase and methanol : water (8:2, v/v) as a mobile phase. The flow rate was 1 ml/min. Results: The studied drug can be determined in the range of 900 - 3000 ng/mL after optimizing the assay conditions to get optimum stationary – mobile phases match. Method validation is performed according to USP-guidelines and different validation parameters like, linearity, accuracy, precision and robustness are calculated and found to be excellent. Conclusion: The proposed method is accurate, sensitive and can be applied for the routine analysis of pamidronate in quality control laboratories.

Abstract A micellar HPLC method was developed for analysis of the antiosteoporosis drug risedronate. The analysis was carried out using a 250 4.6 mm id, 5 m particle size C18 Waters Symmetry column. The mobile phase consisted of 0.02 M sodium dodecyl sulfate + 0.3 triethylamine + 10 n-propanol, prepared in 0.02 M orthophosphoric acid. The pH of the mobile phase was adjusted to pH 6.0, and it was pumped at a flow rate of 0.7 mL/min with UV detection at 262 nm. The method showed good linearity in the range of 280 g/mL, with an LOD of 0.40 g/mL (1.31 106 M) and an LOQ of 1.21 g/mL. The suggested method was successfully applied for the analysis of risedronate in raw material and a tablet formulation, with average recoveries of 99.91 1.30 and 101.52 0.30, respectively. The stability-indicating capability of the proposed method was proved using forced degradation. By changing the pH of the mobile phase to 4.0, the oxidative degradation product could be separated from risedronate.

Abstract A high performance liquid chromatographic (HPLC) method is described for the quantitative determination of primidone in tablets. A ground tablet sample is diluted directly in the mobile phase, at a concentration of about 1 mg/mL of primidone, mixed and deaerated, and filtered. The resulting solution is then quantitated by HPLC. The average spike recoveries for the 50 mg and 250 mg tablets were 101.2% and 99.0%, respectively. The average recovery for an authentic mixture formulated at the 250 mg level was 100.1% with a relative standard deviation of 0.45%.

This method can be conveniently used to detect the possible degradation product in the dosage form of Regorafenib during stability studies (acidic, alkaline, oxidative, thermal and photolytic). The method proved to be effective on the analysis of stressed marketed tablet formulation.
