A simple, rapid, sensitive and accurate UV-spectrophotometric method has been developed for the estimation of Famciclovir in pharmaceutical formulation. The was by using 0.1 N HCl as a solvent absorbance measured at 312 nm. drug exhibited linearity concentration range 2-12 μg/ml with correlation coefficient 0.9978. % recovery found to be 98.62 - 100.5 %. validated per ICH guidelines. proposed i...

The number of poorly water-soluble drug substances in the pharmaceutical pipeline is increasing, and thereby also the need to design effective drug delivery systems providing high bioavailability. One favourable formulation approach is preparation of solid dispersions, where dispersing a poorly water-soluble drug in a water-soluble polymer matrix improves the dissolution behaviour and the bioav...

The present manuscript describes simple, sensitive, rapid, accurate, precise and economical dual wavelength spectrophotometric method for the simultaneous determination of Ambroxol Hydrochloride and Desloratadine Hydrochloride in combined tablet dosage form. The principle for dual wavelength method is “the absorbance difference between two points on the mixture spectra is directly proportional ...

A system using energy-dispersive X-ray diffraction (EDXRD) has been developed and tested using multivariate calibration for the quantitative analysis of tablet-form mixtures of common pharmaceutical ingredients. A principal advantage of EDXRD over the more traditional and common angular dispersive X-ray diffraction technique (ADXRD) is the potential of EDXRD to analyse tablets within their pack...

We propose a general framework for determining optimal relationships for tensile strength of doubly convex tablets under diametrical compression. This approach is based on the observation that tensile strength is directly proportional to the breaking force and inversely proportional to a non-linear function of geometric parameters and materials properties. This generalization reduces to the ana...

Near-infrared spectroscopy (NIRS) is a rapid and nondestructive analytical method. The use of near-infrared spectroscopy in the pharmaceutical industry has been rapidly increasing over the past decade, with particular interest in the analysis of solid dosage forms, such as tablets and capsules [1]. This article describes use of NIR spectroscopy to determine of content the active pharmaceutical ...

No: 687 Health and Hygiene 329 EVALUATION OF THE IMPACT OF TABLET SPLITTING ON THE ACCURACY OF DRUG DOSING H.S. Sellahewa and H.M.D.R. Herath* Department of Pharmacy, Faculty of Allied Health Sciences, University of Peradeniya, Sri Lanka *[email protected] Tablet splitting is commonly used in pharmacy practice. There are many reasons to split tablets such as to get the prescribed dose, to ad...

Terahertz pulsed imaging (TPI) is a recent and nondestructive technique to quantify coating thickness of pharmaceutical tablet film coatings. In this study, TPI is used for the first time to quantify the progress of an active coating process. The dosage form consisted of a push-pull osmotic system comprising a two-layer tablet core with a functional film coating and a laser drilled hole. On top...

This article presents an experimental study of the effects of raised ambient temperature in dies and punches on the compaction of pharmaceutical powders. The experiments use an instrumented hydraulic press having a temperature-controlled enclosure allowing the ambient temperature of die and punch to be varied from 20 to 57 8C. A pharmaceutical powder was compacted at temperatures in this range ...

AIM AND BACKGROUND The present manuscript describes simple, sensitive, rapid, accurate, precise and economical spectrophotometric method for the simultaneous determination of telmisartan and metoprolol succinate in combined tablet dosage form. MATERIALS AND METHODS The method is based on the absorbance correction equations for analysis of both the drugs using methanol as solvent. Telmisartan ...
