Objective: The objective of the present study is to develop simple, rapid, sensitive, accurate and economic stability-indicating ultra-performance liquid chromatographic (UPLC) method for the simultaneous quantification of phenylephrine hydrochloride, chlorpheniramine maleate, paracetamol, guaiphenesin and bromhexine hydrochloride in bulk and tablet dosage form. Methods: The separation of drugs in the chromatographic column was accomplished on Hibar C18 (100 mm x 2.1 mm, 1.6 µm) column at a detection wavelength of 220 nm. The mobile phase was a combination of sodium phosphate monobasic monohydrate buffer (pH was adjusted to 3.5 with orthophosphoric acid) and acetonitrile in the ratio of 70:30 % v/v which was pumped at a flow rate of 0.3 ml/min. The column temperature was maintained at 30 °C and the injection volume was 0.3 µl. Forced degradation studies of drugs were carried out using acid, base, peroxide, light and heat. Results: All the five drugs have been eluted within 3 min. The retention times were found to be 0.834 min, 1.199 min, 1.600 min, 1.979 min and 2.525 min for phenylephrine, chlorpheniramine maleate, paracetamol, guaiphenesin and bromhexine respectively. The correlation coefficient (r2) was found to be 0.999 for all the drugs. The recovery levels were found to be in the range of 99.17 % to 100.69 %. RSD values of drugs were found to be below 2 %. The results of limit of detection and quantitation specified the sensitivity of the developed method. Significant degradation of drugs as a result of stress studies was found in acid, base and peroxide, but they were slightly degraded in photolytic and thermal conditions. The method has effectively resolved the degraded products. All the validation parameters were found to be within the limits according to International Conference on Harmonization (ICH) guidelines. Conclusion: A simple and rapid UPLC method was established for the determination of five drugs. Hence, the proposed method can be employed for the quality control of specified drugs in bulk and pharmaceutical formulation even in the presence of degradation products.

Abstract A simple, rapid LC method is presented for the separation and determination of acetaminophen in analgesic preparations containing up to 6 additional active components. The method uses a C18 reverse phase column, methanol–0.75% acetic acid (1 + 3) mobile phase, and photometric detection in the ultraviolet region. Acetaminophen was effectively separated from chlorpheniramine maleate, phenylephrine hydrochloride, caffeine, salicylamide, aspirin, and phenacetin, as well as from salicylic acid, a degradation product of aspirin. Typical chromatograms of the separation of acetaminophen from the above compounds in synthetic mixture and in commercial multicomponent analgesic preparations are presented, along with reproducibility and recovery data.

A rapid and stability-indicating RP-HPLC method was developed for determination of l-carnitine in tablets. The separation was based on a C18 analytical column using a mobile phase which consisted of 0.05 M phosphate buffer (pH = 3): ethanol (99 : 1), including 0.56 mg/mL of sodium 1-heptanesulfonate. Column temperature was set at 50°C and quantitation was achieved by UV detection at 225 nm. In forced degradation studies, the drug was subjected to oxidation, hydrolysis, photolysis, and heat. Among the different stress conditions, the exposure to acidic and basic conditions was found to be an important adverse stability factor. The method was validated for specificity, selectivity, linearity, precision, accuracy, and robustness. The applied procedure was found to be linear in l-carnitine concentration range of 84.74–3389.50 µg/mL (r2=0.9997). Precision was evaluated by replicate analysis in which relative standard deviation (RSD) values for areas were found below 2.0%. The recoveries obtained (100.83%–101.54%) ensured the accuracy of the developed method. The expanded uncertainty (3.14%) of the method was also estimated from method validation data. Accordingly, the proposed validated and rapid procedure was proved to be suitable for routine analyzing and stability studies of l-carnitine in tablets.

Abstract Lorcaserin (LOR) is selective and potent antiobesity drug that targets the activation of the serotonin 5HT2C receptor. Here a novel, specific, sensitive stability indicating method was developed and validated for the quantitative determination of LOR and its process-related impurities using quality by design principles. By applying experimental design, the authors examine the multifactorial effect of parameters on the critical resolution pair and generated design space representing the robust design. LOR was subjected to stress condition and found stable at all condition, only found significant degradation at oxidative stress condition. The chromatographic separation of degradation product and its process-related impurities were achieved on a Phenomenox Luna phenyl-hexyl column (150 × 4.6 mm × 5 μm), with mobile phase consisting of 10 mM ammonium formate containing 0.1% ammonia solution; pH adjusted to 2.8 with trifluoroacetic acid as solvent A and methanol/acetonitrile (5/95) as solvent B delivered with gradient program at a flow rate of 1.0 mL/min, column temperature was maintained at 25°C and analytes were monitored at 220 nm. The injection volume was 5 μL. The developed RP-LC method was validated and found linear, accurate, specific, selective, precise and robust. The structure of impurities was confirmed by direct mass analysis.

Abstract A simple and reliable high-performance liquid chromatographic method was developed for the simultaneous determination of mixture of phenylephrine hydrochloride (PHENYL), guaifenesin (GUAIF), and chlorpheniramine maleate (CHLO) either in pure form or in the presence of methylparaben and propylparaben in a commercial cough syrup dosage form. Separation was achieved on a C8 column using 0.005 M heptane sulfonic acid sodium salt (pH 3.4 0.1) and acetonitrile as a mobile phase by gradient elution at different flow rates, and detection was done spectrophotometrically at 210 nm. A linear relationship in the range of 30180, 1201800, and 1060 g/mL was obtained for PHENYL, GUAIF, and CHLO, respectively. The results were statistically analyzed and compared with those obtained by applying the British Pharmacopoeia (2002) method and showed that the proposed method is precise, accurate, and can be easily applied for the determination of the drugs under investigation in pure form and in cough syrup formulations.
