The Stability

The stability of pharmaceutical products plays an important role from the economical point of view. There are not many studies that report about the stability of drugs past their expiration dates. The objective of the current study was to determine tablet content and perform dissolution test of expired tablets of amlodipine besylate and tablets where expiry date has not exceeded and to develop simple, accurate, sensitive and stability indicating RP-HPLC method for the determination of per cent drug remained of Amlodipine besylate in the presence of its degradation products in bulk drug, expired tablets and tablets whose expiry date has not been exceeded. Drug was subjected to all stress conditions such as hydrolysis (acidic and alkaline), oxidation (3% H2O2 v/v), photolysis, thermal degradation and humidity study. Content determination was performed using spectrophotometric and RP-HPLC method; the per cent of dissolved substance from tablets during dissolution test was performed using spectrophotometric method and detection was made at 239 nm. All stressed samples were successfully analysed on C18 column using mobile phase phosphate buffer pH 3.5 (50mM): methanol: acetonitrile in the ratio of 30:60:10 v/v/v. A flow rate was maintained at 1.5 ml/min and detection was made at 240 nm. The proposed methods were validated with regard to linearity, sensitivity, and intermediate accuracy and precision. No discrepancies between the results of determination and the declared values range for all the analysed tablets were observed. The results of performed study might suggest that storage of analysed batches of tablets over time period exceeding the expiry date given by the manufacturer did not influence their contents.

The present paper describes the development of quick stability indicating RP-HPLC method for the simultaneous estimation of codeine phosphate and chlorpheniramine maleate in the presence of its degradation products, generated from forced degradation studies. The developed method separates codeine phosphate and chlorpheniramine maleate in impurities/degradation products. Codeine phosphate and chlorpheniramine maleate and their combination drug product were exposed to acid, base, oxidation, dry heat, and photolytic stress conditions, and the stressed samples were analysed by proposed method. The proposed HPLC method utilizes the Shimadzu HPLC system on a Phenomenex C18 column (, 5 μ) using a mixture of 1% o-phosphoric acid in water : acetonitrile : methanol (78 : 10 : 12) mobile phase with pH adjusted to 3.0 in an isocratic elution mode at a flow rate of 1 mL/min, at 23°C with a load of 20 μL. The detection was carried out at 254 nm. The retention time of codeine phosphate and chlorpheniramine maleate was found to be around 3.47 min and 9.45 min, respectively. The method has been validated with respect to linearity, robustness, precision, accuracy, limit of detection (LOD), and limit of quantification (LOQ). The developed validated stability indicating HPLC method was found to be simple, accurate, and reproducible for the determination of instability of these drugs in bulk and commercial products.

Abstract Fosamprenavir calcium is a protease inhibitor widely used in the treatment and prevention of human immunodeficiency virus and acquired immunodeficiency syndrome. This protease inhibitor serves as a prodrug of amprenavir, offering better oral bioavailability. Although this drug was approved by the FDA in 2003, there are few methods established for quantifying the stability for quality control analysis of fosamprenavir-coated tablets. The purpose of the study was to develop and validate a method for determining the stability of fosamprenavir-coated tablets (Telzir®) that may be applied by any quality control laboratory. Chromatographic separation was performed using a Vertical RP-18 column programmed to run a gradient elution with sodium acetate buffer and acetonitrile. Flow rate was 1.2 mL min−1 for a total run time of 15 min. Ultraviolet detection was set at 264 nm and the use of a photodiode array detector in scan mode allowed selectivity confirmation by peak purity evaluation. The analyte peak was found to be adequately separated from degradation products generated during forced degradation studies. Thus, the proposed method was found to accurately indicate stability and was sufficient for routine quantitative analysis of fosamprenavir in coated tablets without interference from major degradation products and excipients.

A trouble-free, simple, specific and highly sensitive stability indicating phase HPLC method was developed for concurrent assessment of Daclatasvir and Sofosbuvir in pure and in their combined tablet formulation. An effectual separation was accomplished by using XDB Phenyl (250 x 4.6mm, 5µ,100 A0) column, mobile phase composition of Acetonitrile: buffer(0.1%v/v Trifluoroaceticacid in water) (50:50 v/v) and isocratic elution at a flow rate of 1ml/min and detection wavelength of 275nm. The extreme stress conditions like hydrolysis with acid and base, peroxide oxidation, thermal decomposition were used as per ICH specifications to assess the stability of the analytes in bulk and dosage forms. The retention times of Daclatasvir and Sofosbuvir were found at 2.8 and 3.7min respectively. The proposed method has linear response in the concentration ranges from 12 to 36µg/ml and 80 to 240 µg/ml for Daclatasvir and Sofosbuvir respectively. The detection and quantification limits calculated as 2.5μg/ml and 7.8μg/ml for DCL, 5.2μg/ml and 15.8μg/ml SOF respectively. All the method validation parameters were met the acceptance limits of Q2 specifications of ICH procedures. The degradation products produced by forced degradation studies were have good resolution from Daclatasir and Sofosbuvir peaks, which represents the methods stability. The proposed RP-HPLC method was highly sensitive, precise, stability indicating and economical. That’s why the method has the capacity to employ in the pharmaceutical manufacturing of Daclatasvir and Sofosbuvir and routine analysis in quality control department.

Results: The retention time for amlodipine besylate and irbesartan were found to be 5.512 and 6.321 min respectively. Linearity was observed over a concentration range 4-32 µg/ml for amlodipine besylate (r2 =0.9999) and 10-70 µg/ml for Irbesartan (r2 =0.9998). The % relative standard deviation (RSD) for Intraday and Interday precision was found to be 0.436 and 0.699 for amlodipine besylate and 0.435 and 0.30 for irbesartan. Amlodipine besylate shown stability towards acidic and thermal whereas in basic, oxidative and photolytic it shown less stability in which it degraded to more extent. Irbesartan shown stability towards thermal conditions whereas in remaining conditions it degrades to more extent especially in oxidative conditions. Conclusion: The developed reverse phase high performance liquid chromatographic (RP-HPLC) method was also found to be simple, precise and sensitive for the simultaneous determination of amlodipine besylate and irbesartan in the tablet dosage form.

In this study, a simple and reliable stability-indicating RP-HPLC method was developed and validated for the analysis of Nystatin in the pharmaceuticals. The chromatographic separation was performed in the isocratic mode on an Ion Pac column; Arcus EP‑C18; 5μm, 4.6×250 mm, 30 °C) using a mobile phase consisting of ammonium acetate 0.05 M buffer/ Methanol mixture (30:70) and a flow-rate of 1.0 mL/min with UV detection at 305 nm. The flow rate was set at 1.0 mL/min. The HPLC analysis method was validated in terms of linearity, precision, accuracy, specificity, and sensitivity, according to International Conference on Harmonization (ICH) guidelines. The results indicated that the retention time was 8 min, and no interferences were observed from the formulation excipients and stress degradation products.  The specificity, linearity, precision, accuracy, LOD, and LOQ of the method were validated. The method was linear over the range of 5–500 μg/mL with an acceptable correlation coefficient (R2 = 0.9996). The method’s limit of detection (LOD) and quantification (LOQ) were 0.01 and 0.025 μg/mL, respectively. The results indicate that this validated method can be used as an alternative method for the assay of nystatin. This validated HPLC method could be used for routine analysis, quality control, and the stability of analysis of Nystatin formulations.
