A simple reproducible stability indicating RP-UPLC method was developed for the simultaneous determination of Ivacaftor, Tezacaftor and Elexacaftor in their combined dosage forms using HSS C18, 1.8μm, 100mm x2.1 mm i.d. column. A mobile phase of phosphate buffer (10mM) pH-4.8 and acetonitrile in the ratio of 70: 30v/v mixture was used for separation and quantification of ivacaftor, tezacaftor and elexacaftor. The present drug analytes were run at a flow-rate of 0.3ml/ min at 30°C temperature. The injection volume was 2μL and with ultraviolet detection at 270nm. Under these conditions, elexacaftor, ivacaftor and tezacaftor were eluted at 0.72min, 1.4min and 1.9min respectively with a total run time shorter than 5min. The developed method was validated according to International Conference on Harmonization (ICH) guidelines. The developed RP-UPLC method was applied successfully for quality control assay of Ivacaftor, Tezacaftor and Elexacaftor in their combination drug product.

Abstract For type 2 diabetes treatment, combinations of drugs from the thiazolidinedione and sulfonylurea groups are now available in the same tablet or capsule. Therefore, a stability-indicating and validated HPLC method was developed for simultaneous determination of pioglitazone, rosiglitazone, and glipizide in combined dosage forms. The examined drugs were subjected to different conditions such as acid and base, temperature, and UV light, and degradation of pioglitazone and glipizide was observed under thermal and acidic stress. However, selectivity of the presented method for pioglitazone, rosiglitazone, and glipizide assay against their degradation products was confirmed. It was also demonstrated to be robust, resisting small deliberate changes in pH of the buffer, flow rate, and percentage of acetonitrile in the mobile phase. The presented method utilizes a LiChrospher RP18 column (125 4.0 mm), acetonitrile in phosphate buffer at pH 4.3 (40 + 60, v/v) as the mobile phase, and UV detection at 225 nm for pioglitazone/glipizide or 245 nm for rosiglitazone/glipizide. The method was validated with respect to linearity, precision, and accuracy. Finally, the elaborated procedure was applied for the QC of pioglitazone/glipizide and rosiglitazone/glipizide mixtures.

A short selective, precise, accurate and sensitive stability-indicating gradient LC-MS/MSn method was developed for the quantitative determination of process-related impurities and degradation products of Levosalbutamol in pharmaceutical respules formulations. During the stress study, the degradation products of Levosalbutamol were well-resolved from Levosalbutamol and its impurities and the mass balances were found to be satisfactory in all the stress conditions, thus proving the stability-indicating capability of the method. The developed method was validated as per ICH guidelines with respect to specificity, linearity, limit of detection and quantification, accuracy, precision, ruggedness, and robustness. During the stability analysis of the drug product, one unknown impurity was detected by the above stability-indicating method. The flow rate was 0.8 ml/min and effluent was monitored at 242nm. Retention time was found to be 2.237±0.08 min. The LOD and LOQ values were found to be 0.20984 (μg/ml) and 0.6359 (μg/ml) respectively.

Abstract Column liquid chromatography (LC) and thin-layer chromatography (TLC)densitometry methods are described for simultaneous determination of acediasulfone (Ace) and cinchocaine (Cinco). In the LC method, the separation and quantitation of the 2 drugs was achieved on a Zorbax C8 column (5 μm, 150 × 4.6 mm id) using a mobile phase composed of methanol-phosphate buffer, pH 2.5 (66 + 34, v/v), at a flow rate of 1 mL/min and ultraviolet detection at 300 and 327 nm for Ace and Cinco, respectively. The method showed linearity over concentration ranges of 20-200 and 45685 μg/mL, respectively. In the TLCdensitometry method, a mobile phase composed of methanol-tetrahydrofuran-acetic acid (45 + 5 + 0.5, v/v/v) was used for the separation of the 2 drugs. The linearity range was 0.5-4 and 2-9 μg/spot, respectively. In addition, stability indicating TLCdensitometry method has been developed for determination of cefuroxime sodium in the presence of 570% of its known hydrolytic degradation products. The mobile phase butanol-methanol-tetrahydrofuran-concentrated ammonium hydroxide (50 + 50 + 50 + 5, v/v/v/v) was used. The concentration range was 210 g/spot. The optimized methods proved to be specific and accurate for the analysis of the cited drugs in laboratory-prepared mixtures and dosage forms. The obtained results agreed statistically with those obtained by the reference methods.

Abstract Two selective and sensitive chromatographic methods were developed for simultaneous determination of new combination of quinfamide and mebendazole in bulk powder and in pharmaceutical formulation. The first method is HPTLC by which separation was obtained using silica gel HPTLC F254 plates and a simple mobile phase consisting of methanol:toluene (2:6, v/v) and the separated bands were scanned at 254 nm. The second method RP-HPLC that comprised isocratic separation of both drugs on a Phenomenex C18 column using a green mobile phase consisting of double distilled water:methanol (30:70, v/v) at a flow rate of 0.8 mL/min and UV detection at 254 nm. The developed methods were validated and proved to meet ICH guidelines. Successful application of the developed methods was carried out for determination of quinfamide and mebendazole in Vermox Plus® tablets. Statistical comparison between the developed chromatographic methods and the reported simultaneous equation spectrophotometric method showed that there was no significant difference between them, proving the ability of applying the proposed methods in quality control testing of the studied drugs. The developed methods are considered the first chromatographic methods for simultaneous determination of quinfamide and mebendazole; moreover, they offered sensitive and selective eco-friendly methods for analysis of the studied drugs.

Abstract Background Felodipine is a calcium channel blocker used together with metoprolol succinate for treatment of hypertension. Objective Two chromatographic methods were developed for simultaneous determination of felodipine (FEL) and metoprolol succinate (MET), and their major metabolites, dehydrofelodipine and metoprolol acid, respectively. Methods The first method was RP-HPLC which comprised separation of the studied components by gradient elution using a Phenomenex C8 column and a mobile phase composed of water (adjusted to pH 3.5 with o-phosphoric acid)–acetonitrile – methanol (45:40:15, by volume) for the first 6 min and (30:60:10, by volume) for the next 4 min at a flow rate of 1 mL/min followed by UV detection of the eluted peaks at 225 nm. The second method was an HPTLC method where separation was achieved using a mobile phase consisting of toluene–ethyl acetate–methanol–ammonia–formic acid (10:5:2.5:0.3:0.1, by volume) and scanning of the separated bands at 225 nm. Results Validation of the developed methods was done according to ICH guidelines. Successful application of the developed methods was carried out for determination of the studied drugs in human spiked plasma and in Logimax® tablets. Conclusions The developed RP-HPLC and HPTLC methods can be further applied for quality control testing of the studied drugs. Highlights RP-HPLC and HPTLC methods for determination of FEL, MET and their major metabolites. The developed methods were successfully applied for determination of FEL and MET in Logimax® tablets.
