A simple, precise and accurate RP-HPLC method was developed for the determination of Plerixafor in bulk and pharmaceutical dosage forms. The estimation was carried out on Xterra RP 18 (4.6 x 250mm, 5µm) column using a mixture of Methanol: Water (50:50% v/v) as the mobile phase at a flow rate of 0.8ml/min, the detection was carried out at 215nm. The method was validated for linearity, accuracy, precision, specificity, limit of detection and limit of quantification and robustness as per ICH norms. The retention time of the Plerixafor was 5.481 min. The method produce linear responses in the concentration range of 10-50mg/ml with correlation coefficient (r2) of 0.999. The proposed method is useful for the estimation of plerixafor in its pure and injection dosage...

Transition metal doped zinc oxide particles were synthesized in aqueous phase adopting a low cost, easy and environmental friendly route. The precursors used in the preparation of Co doped ZnO (Zn0.95Co0.05O) and ZnO (Zn0.9oCo0.1O) by wet process are zinc acetate dehydrates cobalt chloride, sodium hydroxide, di-ethylene glycol and double distilled water. The doped ZnO particles were characterized by using scanning electron microscope (SEM), energy dispersive X-ray (EDX), Fourier transforms infrared spectroscopy (FTIR). The study constitutes the basis for developing versatile applications of transition metal doped ZnO...

Objective: In the present investigation, pharmacognostical, physicochemical characteristics, thin layer chromatography and anthelmintic activity of different extracts of Swertia alata Royle were studied. Methods: Different types of preliminary and phytochemical analysis and quantitative estimation have been done along with HPTLC fingerprinting. Two concentrations (30 mg/mL and 60 mg/mL) of different extracts of S. alata were used for anthelmintic activity against Indian earthworm Pheretima posthuma. Results: The microscopic study revealed the presence of lignified vessels and cruciferous stomata. The chemical tests showed the presence of glycosides, saponins, tannins, proteins and steroids. HPTLC fingerprinting of different extracts showed number of spots due to presence of various phytochemical compounds. The results of anthelmentic activity were expressed in terms of time of paralysis and time for death of worms. Piperazine citrate (10mg/mL and 30 mg/mL) was used as a reference standard and normal saline as a control group. Conclusions: These observations will be useful in evaluation of pharmacognostical and phytochemical standards to ensure the purity and quality of this plant. The anthelmintic activity...

The main aim of this study was to develop Mebeverine colon specific drug delivery system with increased stability of drug in stomach and small intestine. This stability of drug was achieved by coating of the drug core with Chitosan and Ethyl cellulose polymers by direct compression using tablet punching machine. Mebeverine was a drug whose therapeutic role is in the treatment of Irritable Bowel Syndrome and the associated abdominal cramping. It works by relaxing the muscle in and around the gut. It was a musculotropic antispasmodic drug without having anticholinergic side effects. The drug is also indicated for gastrointestinal spasm secondary organic disorder. The colon is a site where both local and systemic delivery of drugs can take place. Local delivery allows topical treatment of inflammatory bowel disease. However, treatment can be made effective if the drugs can be targeted directly into the colon, thereby reducing the systemic side effects. This study, mainly compares the primary approaches for Colon Specific Drug Delivery namely prodrugs, pH and time dependent systems,...

There are various treatment regimens including different antibiotics and antacid medications for eradicating Helicobacter pylori to compare the effectiveness of 7-day concomitant regime with classic triple regimen in eradicating H. pylori. In this randomized clinical trial, 206 dyspeptic patients proven H. pylori infection, attended to a gastrointestinal clinic in Khorramabad (west of Iran) were studied. The patients were randomly divided in two equal groups. Classic group were treated for 14 days with a regimen including omeprazole 20mg, amoxicillin 1g and clarithromycin 500mg, twice daily. In concomitant group, the patients were treated for 7 days with a regimen including omeprazole 20mg, amoxicillin 1g, clarithromycin 500mg and metronidazole 500mg twice daily. During the treatment period and a week after the end of treatment, the patients were evaluated in terms of possible side-effects and medication acceptance and tolerance. For confirmation of eradication, 6 weeks after the end of treatment, urea breath test with carbon 13 (UBT) was done for both the groups. Data were analyzed using descriptive statistics, T-test and chi-square test,...
