Voriconazole is used for the treatment of variety of fungal infections caused by aspergillosis, candidiasis, coccidioidomycosis, histoplasmosis, penicilliosis etc. Voriconazole belongs to triazole class. Voriconazole is mainly used to treat certain patients who are not responding to other anti-fungal drugs. It works by slowing the growth of the fungi that cause infection. A new validated reverse phase stability indicating liquid chromatographic method has been developed for the assay of Voriconazole in presence of an internal standard (Rufinamide) tablets. Forced degradation studies were performed to define the selectivity and specificity of the method. Linearity was observed over the concentration range 1.0-100μg/mL with linear regression equation y = 0.4489x – 0.1262 (r2 = 0.9999). The LOQ and LOD were found to be 0.8934μg/mL and 0.2921μg/mL. The present stability indicating RP-UFLC method was validated as per ICH guidelines and can be useful for the assay of tablets and injections and also for the kinetic studies.

Nilotinib hydrochloride monohydrate is a tyrosine kinase inhibitor approved for the treatment of chronic myelogenous leukemia. A new stability indicating ultra-fast liquid chromatographic (RP-UFLC) method was developed for the quantification of Nilotinib and validated. Mobile phase consisting of a mixture of sodium acetate (pH 5.0): acetonitrile (40: 60, v/v) was used with flow rate 0.8 mL/min (UV detection at 254 nm) for the chromatographic study. Nilotinib obeys Beer-Lambert’s law over the concentration range of 0.2-80 μg/mL (R2 = 0.9999) with linear regression equation y = 175336x +20675. The LOQ was found to be 0.1897 μg/mL and the LOD was found to be 0.0619 μg/mL. Forced degradation studies were performed such as acidic, alkaline, oxidation and thermal degradations and the method was validated as per ICH guidelines.

A new naproxen amide prodrug was synthesized and spectrally characterized and a simple, precise, and accurate stability-indicating RP-HPLC method was developed and validated for determination and chemical hydrolysis study of the prodrug. Forced degradation studies were conducted as per the International Conference on Harmonization (ICH) guidelines to establish the stability-indicating power of the method. Separations were performed on a C18 column (150 × 4.6 mm i.d., 5 μm p.s.). The mobile phase consisted of acetonitrile and phosphate buffer pH 4.0 in the ratio 60 : 40. The flow rate and injection volume were 1.0 mL/min and 15 μL, respectively. The peaks were monitored at 272 nm. The average retention time is 5.136 min. The linearity of the method was investigated in the range of 10–50 μg/mL and r2 was found to be larger than 0.9987. The LOD and LOQ were found to be 1.853 and 5.615 μg/mL, respectively. Results indicated that the degradants are well resolved and separated from the prodrug. Hydrolysis kinetics studies were carried out in buffer solutions (pH 1.2, 5.5 and 7.4) to establish the fate of the prodrug. The half-lives in the respective buffers were 23.5, 262, and 334 hours indicating sufficient stability to attain the goal of oral delivery.

A stability indicating HPTLC method was developed and validated for fixed dose combination of cefpodoxime proxetil and ofloxacin. TLC plates precoated with silica gel 60F254 were used as stationary phase and n propanol: ammonia (7:3 v/v) was used as mobile phase. Densitometric scanning was carried out at 290nm. Specificity of the method was established by peak purity studies. Method was validated as per ICH guidelines Q2 (R1) for accuracy, precision, linearity, sensitivity and robustness. Both the drugs were subjected to hydrolytic (acidic and basic), oxidative, thermal and photolytic stress as per ICH guidelines Q1A (R2) and Q2B. Forced degradation studies were performed by using design of experiments approach, the most widely used mathematical model. Such experimental design approach can replace conventional trial and error experimentation to achieve optimum degradation.
