Stability Indicating RP-HPLC Assessment and Stability Testing of Tazarotene and Halobetasol in Lotion Formulation

stability and attraction domains of traffic equilibria in day-to-day dynamical system formulation

در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...

A Stability Indicating Rp-hplc Method for Simultaneous Determination of Halobetasol Propionate and P-chlorocresol in Creams

A simple, selective, accurate high performance liquid chromatographic method was developed and validated for an analysis of Halobetasol Propionate and p-Chlorocresol in pharmaceutical formulations. Chromatographic separation achieved by gradient programme on a C18 column (Waters Novapak C-18, 250 x 4.6mm, 4μm column) utilizing a mobile phases of A (pH 2.5 phosphate buffer) and B (mixture of buf...

Stability indicating RP HPLC method for determination of levitiracetam in pharmaceutical formulation

The article reports on a development of RP-HPLC method for the quantitative determination of Levetiracetam in tablet dosage forms. The chromatographic separations were performed using Phenomenex C18 (250 mm x 4.6 mm i.d, 5 μm particle size) column at 40 oC temperatures. The optimum mobile phase consisted of methanol, water and acetonitrile in the ratio of 30:10:60. Auto sampler 20 μl was used ...

Development and validation of a fast, simple and specific stability indicating RP-HPLC method for determination of Dexpanthenol in eye gel formulation.

AIn this study a simple and reliable stability-indicating RP-HPLC method was developed and validated for analysis of Dexpanthenol in an artificial tear formulation. The chromatographic separation was performed on a HPLC C18 column (25.0 cm  4.6 mm, 5 m) using a mixture of 0.037 M monobasic potassium phosphate in water (adjusted with 0.1% (v/v) phosphoric acid to a pH of 3.2) and methanol (90:...
