• membrane
  • d) a contact adhesive lamina adjacent and below the microporous membrane lamina by which said bandage is affixed to the skin comprising about 10 to about 200 μg scopolamine base per cm 2 effective surface area dispersed in a gelled mixture of said mineral oil and said polyisobutene. (google.co.uk)
  • An advantage of a transdermal drug delivery route over other types of medication delivery such as oral, topical, intravenous, intramuscular, etc. is that the patch provides a controlled release of the medication into the patient, usually through either a porous membrane covering a reservoir of medication or through body heat melting thin layers of medication embedded in the adhesive. (wikipedia.org)
  • Drug - Drug solution in direct contact with release liner Adhesive - Serves to adhere the components of the patch together along with adhering the patch to the skin Membrane - Controls the release of the drug from the reservoir and multi-layer patches Backing - Protects the patch from the outer environment Permeation Enhancer - These are permeation promoters for drugs, which increases delivery of drug. (wikipedia.org)
  • In general, TDSs have an outer impermeable membrane, a reservoir containing a drug solution and perhaps a penetration enhancer, a rate-limiting membrane that covers a defined area, and an adhesive frame. (pharmacytimes.com)
  • Drug is released from a reservoir system by first dissolving in the polymer membrane, diffusing across it. (gatewaycoalition.org)
  • hollow
  • The delivery device includes a hollow body with an inlet port at its proximal end for insertion of the agent, a reservoir for holding the agent and a delivery mechanism for the sustained delivery of the agent from the reservoir to the patient. (google.es)
  • 12 . The delivery device of any one of claims 1 through 11 , further comprising a hollow body at least partially housed in the reservoir. (google.es)
  • 15 . The delivery device of claim 14 further comprising at least one aperture in a portion of the hollow body housed in the reservoir, whereby the at least one aperture provides communication between the contents of the hollow body and the contents of the reservoir. (google.es)
  • Reservoir systems could also be in the form of microcapsules or hollow fibers. (gatewaycoalition.org)
  • delivery
  • a delivery mechanism for delivering the agent from the reservoir to the interior of a patient's eye at a desired rate. (google.es)
  • In addition, reservoir devices are not suitable for delivery of high molecular weight drugs, because the drug will not diffuse through the polymer. (gatewaycoalition.org)
  • similar
  • It was more effective than oral meclizine or cinnarizine, similar to oral scopolamine 0.6mg or promethazine plus ephedrine, and the same as or superior to dimenhydrinate. (springer.com)
  • It is possible to derive similar equations for various different geometries of reservoir systems. (gatewaycoalition.org)
