Formulation and evaluation of oil entrapped gastroretentive floating gel beads of loratadine.
A gastro retentive controlled release system of loratadine was formulated to increase the residence time in stomach and to modulate the release behaviour of the drug. Oil entrapped floating microbeads prepared by the emulsion gelation method were optimized by 23 factorial design and a polymer ratio of 2.5:1.5 (pectin/sodium alginate) by mass, 15% (m/V) of oil (mineral oil or castor oil) and 0.4...
متن کاملFormulation and evaluation of domperidone loaded mineral oil entrapped emulsion gel (MOEG) buoyant beads.
Alginate based mineral oil entrapped emulsion gel (MOEG) buoyant beads of domperidone were prepared by emulsion gelation technique. The prepared beads were evaluated for particle size, surface morphology, buoyancy, actual drug content and entrapment efficiency. Effect of different oils (castor oil, olive oil and linseed oil) and oil concentrations (10%, 15% and 20%, w/w) on uniformity, homogene...
متن کاملFormulation and In-vitro Evaluation of pH-Sensitive Oil Entrapped Polymeric Blend Amoxicillin Beads for the Eradication of Helicobacter pylori
Oral pH sensitive drug delivery systems are of utmost importance as these systems deliver the drug at specific part of the gastrointestine (GI) as per the pH of GI, resulting in improved patient therapeutic efficacy and compliance. The pH range of fluids in various segments of the GI tract may provide environmental stimuli for drug release. The aim of this study was to design buoyant beads c...

متن کاملFormulation and Evaluation of Gastroretentive Floating Tablets of Domperidone Maleate
The low bioavailability (15%) and good solubility of Domperidone Maleate in acidic pH following oral administration favours development of a gastro retentive formulation. Gastroretentive floating matrix tablets of Domperidone Maleate were successfully prepared with hydrophilic polymers like HPMC K4M, HPMC K15M and HPMC K100M. From the Preformulation studies for drug excipients compatibility it ...
