The new stability-indicating high performance liquid chromatography (HPLC) method has been developed and validated with different parameters for atenolol (ATE) and nifedipine (NIFE) in the combined dosage form. The chromatographic conditions were optimized using a mobile phase of MeOH:OPA (70:30) with a flow rate of 0.7 mL/min. Column (C18) of 4.6 × 250 mm dimension was used as a stationary phase; the particle size capacity of the column was 5 μm. The detection was carried out at 233 nm. The method was validated according to ICH guidelines for linearity, precision, repeatability, the limit of detection (LoD), and limit of quantitation (LoQ). The response was found to be linear in the concentration range of 20 to 100 mcg/mL for ATE and 1 to 5 mcg/mL for NIFE. The developed method shows the minimum quantity of drugs to be identified (LoD) and minimum drug to be quantified (LoQ). The LoD and LoQ were found to be 0.1415 and 0.4289, respectively, for ATE, and 0.1834 and 0.5558, respectively, for NIFE. The method was linear, simple, precise, and accurate and, therefore, suitable for routine analysis of drugs in tablet form. The forced degradation studies were also done through the exposure of analyte solution to four different stress conditions.

The aim of this study was to develop and validate a high performance liquid chromatography (HPLC) method for the determination of thirteen selected pharmaceutical compounds (metformin, amoxicillin, chloroquine, theophylline, trimethoprim, caffeine, norfloxacin, ciprofloxacin, acetylsalicylic acid, doxycycline hyclate, metronidazole, albendazole and cloxacillin) in bulk and tablet dosage form. Chromatographic separation using a Kromasil C18 column, gradient elution with aqueous formic acid (0.1%), methanol and acetonitrile, a UV absorption wavelength of 250 nm and a mobile phase flow rate of 1 mL/min over a 22 min run time was optimized for complete separation of the selected target compounds. The method was validated and results for: linearity, precision, sensitivity, accuracy, specificity, suitability and method robustness were obtained and met the ICH guidelines. Calibration curve correlation coefficients ranged from 0.9985-0.9998 and the percentage relative standard deviations for repeated analysis was below 5%, indicating acceptable method precision. The limits of detection (LODs) and quantification (LOQs) ranged from 0.020-0.27 µg/L and 0.080-0.91 µg/L, respectively. The accuracy study yielded recoveries in the ranges 86.0-102% for pure compounds and 90.9-106% for compounds in tablet dosage form. The method is robust for small or deliberate changes to the chromatographic parameters and found to be appropriate for analysis of tablets for the determination of the thirteen pharmaceuticals.                     KEY WORDS: Pharmaceuticals, Bulk determination, Tablet dosage, High performance liquid chromatography, Method development, ICH guidelines   Bull.

A reversed phase high performance liquid chromatography (RP-HPLC) method was developed, validated and used for the quantitative determination of rabeprazole sodium (RP) and itopride hydrochloride (IH), from its tablet dosage form. Chromatographic separation was performed on a Phenomenex C18 column (250 mm × 4.6 mm, 5 μm), with a mobile phase comprising of a mixture of 50 mM ammonium acetate buffer and methanol (20:80v/v), pH 4.5 adjusted with acetic acid, at a flow rate of 1.3 mL/min with detection at 286 nm. Separation was completed in less than 10 min. As per International Conference on Harmonization (ICH) guidelines the method was validated for linearity, accuracy, precision, limit of quantitation and limit of detection. Linearity of RP was found to be in the range of 37.5-375 μg/mL and IH was found to be in the range of 5-50 μg/mL. The correlation coefficients were 0.9997 and 0.9995 for RB and IH respectively. The accuracy of the developed method was found to be 98.6-100.7 for RP and 99.42 -100.81 for IH. The experiment shows the developed method is free from interference of excipients. It indicates the developed RP-HPLC method is simple, linear, precise and accurate and it can be conveniently adopted for the routine quality control analysis of the tablet dosage form.

Using simple, precise, and accurate reversed-phase high-performance liquid chromatography (RP-HPLC) method, the synchronous of lornoxicam (LOR) and paracetamol (PCM) in the unite dosage form in the tablet has been established and confirmed. Acetonitrile: methanol: water is the mobile phase of the RP-HPLC method (pH adjusted with orthophosphoric acid), pH 3.8 (50:30:20 v/v/v), a diode array detector tuned to 290 nm was used to detect the signal. For LOR and PCM, chromatographic technique linearity was obtained in the concentration, ranges of 2-40 and 8–150 g/mL, respectively. In HPLC techniques, the recoveries were in the range of 99.85 0.0642 percent for LOR and 99.73 0.187 percent for PCM. Both approaches may be used to analyze the medicines in a pharmaceutical formulation regularly. The results of the analysis were statistically verified.
