microparticles offer various significant advantages as drug delivery systems, including: (i) an effective protection of the encapsulated active agent against (e.g. enzymatic) degradation, (ii) the possibility to accurately control the release rate of the incorporated drug over periods of hours to months, (iii) an easy administration (compared to alternative parenteral controlled release dosage ...

in the present study, floating drug delivery beads (fdds) were prepared with sodium alginate/ starch blend as a matrix, sodium hydrogen carbonate as a pore forming agent, methyl cellulose as a binder and barium chloride solution as a hardening agent. in order to prepare the beads with different porosity and morphology the ratio between pore forming agent to polymer blend and ratio of the consti...

conclusions conservative management is successful in the vast majority of patients with spinal headache. interventional procedures are required in a small fraction of patients for symptomatic relief. case presentation intrathecal drug delivery system (idds) was initially used for the management of chronic malignant pain; it has since been used to manage pain from other nonmalignant conditions a...

      Several plant extracts and phytoconstituents, despite having excellent bioactivity in vitro, demonstrate less or no in vivo actions due to their poor lipid solubility or improper molecular size or destruction in gut. Drug delivery system for polyphenolic phytoconstituents (phytosomes) was prepared by complexing polyphenolic phytoconstituents with phospholipid mainly phosphatidylcholine wh...

to answer challenge of targeted and controlled drug release in oral delivery various materials were studied by different methods. in the present paper, controlled metal based drug (pd(ii) complex) release manner of β‑lactoglobulin (β-lg) nanoparticles was investigated using mathematical drug release model in order to design and production of a new oral drug delivery system for gastrointestinal ...

in the long-term management of ulcerative colitis patients, repeat dosing maybe required. since 5-asa is largely absorbed from the upper intestine, selective delivery of drugs into the colon may be regarded as a better method of drug delivery with fewer side effects and a higher efficacy. the aim of this study was to prepare and evaluate a double coated multiparticulate system for 5-asa deliver...

The oral route is the best and most popular for administration of drugs in systemic circulation. There are number which given through route. Gastro-retentive drug delivery system very important system. gastro-retentive prolonged time git also improve their bioavailability. These widely used site specific treatment disorders diseases. approaches gastro retentive such as floating system, mucoadhe...
