Typhoid fever (TF) is an acute systemic infection caused by Salmonella Typhi, Salmonella Para Typhi A and Salmonella Para Typhi B. It is transmitted by the fecal oral route mainly via contaminated food and water. The developing countries have high rate of morbidity and mortality due to Typhoid fever, epidemics take place in developed world also. There are increased incidences of multi drug resistant in S. typhi strains that has further complicated its management and only a few antibiotics are now effective in treatment of typhoid. We report that the aqueous extracts of fruit peel Citrus sinensis (L.) confer anti typhoid activity against Salmonella Typhi, Salmonella Para Typhi A and Salmonella Para Typhi B respectively on comparison with ciprofloxacin.
Key words: Typhoid fever, Salmonella Typhi, Salmonella Para Typhi A , Salmonella Para Typhi B, anti typhoid activity, Citrus sinensis.

Esomeprazole Magnesium Trihydrate, very slightly soluble (0.3mg/ml) proton pump inhibitor belongs to Class II of BCS with elimination half life of 1-1.5 hrs. The aim of present study was to prepare inclusion complexes with improved solubility of Esomeprazole Magnesium Trihydrate and to find out the best suitable complexing agent for solubility enhancement of drug. For the purpose, inclusion complexes (C1-C10) of Esomeprazole Magnesium Trihydrate were formulated with Complexing Agents (1:1.5-1:5.5 molar ratio). 2-Hydroxy Propyl-ß-Cyclodextrin (C1-C5) and Ethylene Di-amine Tetra Acetic Acid Disodium Salt (C6-C10) were taken as complexing agents. As per results, Complexing agents contributed to solubility enhancement of drug. Comparative solubility study was performed to find out more suitable complexing agent among the two. Solubility profile of inclusion complexes (C3 & C7) were found to revealed the 15-20 FOLD increase in solubility of pure drug. Dissolution Profile of inclusion complex tablets showed high release rate indicating improvement in solubility and dissolution of drug and Formulation C7 (1:2.5 molar ratio of Esomeprazole Magnesium Trihydrate : Ethylene Diamine Tetra Acetic Acid Disodium Salt) showed maximum drug release. In present study, we have concluded that with a best suited ratio of 1: 2.5 (drug: EDTA), Ethylene Diamine Tetra Acetic Acid Disodium Salt was better complexing agent.
