Artemisia, being the widely distributed genus of the plant family Asteraceae encompasses about 500 species. Among them, Artemisia absinthium (A. absinthium) is a well-known herb commonly known as Wormwood and Afsanteen. A. absinthium reported to possess several therapeutic benefits in fever, inflammation, epilepsy, gastric problems and urinary disorders. Review of literature included PubMed, Science Direct searches with 'A. absinthium' and 'Wormwood' as initial key words. The search was further refined by looking for terms such as 'Constituents' (or composition) and 'Activity' (or effect) within the results. The major bioactive constituents of Wormwood are mono and sesquiterpenes. The present review comprises up to date information of traditional uses, phytochemistry and pharmacology of A. absinthium. The A. absinthium is a rich source of chemically novel compounds and needs elaborate screening strategies to dwell into the pharmacological effects of its phytoconstituents at the molecular level. This review article provides preliminary information and gives a direction for the basic and clinical research on A. absinthium.
Objective: In the present study, we aimed to optimize, characterize and evaluate poly lactic-glycolic acid nanoparticles of cilnidipine for improved permeation across the gastrointestinal tract.Methods: Poly lactic-glycolic acid-cilnidipine (PLGA-CIL) nanoparticles were prepared by an emulsification solvent evaporation/diffusion method using polyvinyl alcohol (PVA) as a surfactant. The prepared nanoparticles were successfully characterized for particle size, shape, drug release and pharmacological effect.Results: Polymeric nanoparticles of cilnidipine at a dose of 10 mg had a small particle size of 272 nm with smooth morphology. Nearly 81% of the drug was encapsulated in the polymeric structure and showed 18.99±0.59% of release at pH 1.2 within 3h, however, at pH 6.8 the release was 80.89±1.59%. The formulation had a better antihypertensive effect on methylprednisolone-induced hypertensive rats. The relative bioavailability of the nanoparticles was found to be 2.44 and 2.94 fold higher than the tablet and drug suspension respectively.
Conclusion:The results demonstrated that the novel delivery system offers an effective strategy for treatment of hypertension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
