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...

FULLY implantable devices or drug–device combinations, such as intrathecal drug delivery (DD) systems and spinal cord stimulation (SCS) systems, increasingly are used for the treatment of chronic intractable pain. Another approved indication for intrathecal DD systems is the administration of intrathecal baclofen (ITB) to treat medically intractable spasticity of spinal or cerebral origin. Alth...

Patients with leptomeningeal carcinomatosis face a particularly grim prognosis. Current treatment consists of intrathecal delivery of methotrexate (MTX) or cytosine arabinoside (Ara-C) via Ommaya reservoir or lumbar puncture. Yet despite these interventions, the median survival after diagnosis is only 4-7 months. To address inherent shortcomings of current treatments and provide a more effectiv...

      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 ...

Abstract Background Appropriate drug distribution is needed for effective treatment of brain metastases and leptomeningeal carcinomatosis. Lack proper bioavailability in the CNS contributes to poor outcome these patients. EnClear Therapies has developed a device delivering intrathecal therapeutics utilizing active control CSF flow through an external pump. Herein, we look at delivery methotrexa...
