The present manuscript describes simple, sensitive, rapid, accurate, precise and economical spectrophotometric method for the simultaneous determination of cefpodoxime proxetil and ofloxacin in combined tablet dosage form. The method is based on the simultaneous equations for analysis of both the drugs using methanol as solvent. Cefpodoxime proxetil has absorabance maxima at 236 nm and ofloxacin has absorbance maxima at 299 nm in methanol. The linearity was obtained in the concentration range of 5-29 μg/ ml and 1-13 μg/ml for cefpodoxime proxetil and ofloxacin respectively. The concentrations of the drugs were determined by using simultaneous equations at both the wavelengths. The method was successfully applied to pharmaceutical dosage form because no interference from the tablet excipients was found. The suitability of this method for the quantitative determination of cefpodoxime proxetil and ofloxacin was proved by validation. The proposed method was found to be simple and sensitive for the routine quality control application of cefpodoxime proxetil and ofloxacin in pharmaceutical dosage form. The result of analysis has been validated statistically and...

The safety and efficacy of a pharmaceutical dosage form can be guaranteed when its quality is reliable. The efficacy of pharmaceutical dosage forms generally depends on their formulation properties, and manufacturing methods, hence it is likely that the quality of dosage form may vary. The aim was to evaluate the quality of paracetamol tablet marketed in Somali region of Ethiopia. The study was exclusively experimental that used BP, USP and other standard books to check the in vitro quality of Paracetamol tablet using different analytical techniques and procedure. Test for weight variation, friability, disintegration time, identification test and assay were conducted. All of the brands under the study were within the specification for weight variation test. But from the contraband brands, two for friability, one for disintegration and all for percentage content paracetamol failed to satisfy the requirement though all of the products contain the wright active ingredients. The research has showed that the quality of contraband tablets were below the standard in contrast to the legal paracetamol tablet...

Trihexyphenidyle is a lipophilic antiparkinsonian drug with short half life. Practically slightly soluble in water makes formulation and delivery difficult. By formulating the same in the microcapsule by using biodegradable polymer Eudrajit L 100 and S 100, the half life and solubility can be altered and hence drug release pattern. Trihexyphenidyle microcapsules were prepared by solvent evaporation method by using different drug-polymer ratio (1:2, 1:3, 1:4, 1:5). Prepared microcapsules were evaluated for the particle size, percentage yield, incorporation efficiency, flow property and in vitro drug release at pH 6.8 for 12 hours. From the result we can conclude that as the concentration of polymer increases, it affects the particle size, percentage yield and drug release of micro capsules. The formulation F2 shows the excellent flow properties, particle size, percentage yield (91.24%), incorporation efficiency (94.59%) and percentage drug release (95.88%) for a period of 12 hrs. Results of the present study indicate that Trihexyphenidyle microcapsules can be successfully designed to develop sustained drug delivery, that reduces the dosing frequency and...

A simple, precise and accurate UV-Spectrophotometric method has been developed and validated for estimation of secnidazole in bulk and tablet dosage form. It shows maximum absorbance at 313 nm with methanol and water (30:70). Estimation was carried out by A(1%1cm) and by comparison with standard. Calibration graph was found to be linear (r2 =0.09998) over concentration range of 1-4µg/ml. The proposed methods appear to be simple, sensitive, and reproducible when checked for parameters like accuracy, precision, limit of detection for routine determination of secnidazole in bulk as well as in tablet. The methods can be adopted in its routine...

Starch was extracted from the grains of finger millet (Eleusine corocana), by steeping in water for 24 hours. The extracted starch was used as a disintegrant, at the concentrations of 2.5-12.5%w/w to compressed paracetamol tablet in comparism with maize starch BP. Results show that, there is no significant difference in the disintegration time or dissolution rate of tablets containing the two starches. Tablets containing Eleusine corocana met compendia requirements for disintegration time and dissolution rate. The starch is recommended as a disintegrant in tablet...
