Patches are broadly used in drug delivery. The most characteristic examples are ocular (eye) and transdermal patches. Ocular patches are typical membrane-controlled reservoir systems. The drug, accompanied by carriers, is captured in a thin layer between two transparent, polymer membranes, which control the rate of the drug release . An annular white-coloured border is surrounding the reservoir for …Author: Dimitrios F. Stamatialis, Bernke J. Papenburg, Miriam Gironès, Saiful Saiful, Srivatsa N.M. Bettahal...

In general, reservoir systems comprised of the drug segregated from a rate-controlling membrane layer (core-shell structure) and can be categorized to have either a constant activity source or non-constant activity source . For devices with a constant activity source, the initial drug concentration is higher than the drug solubility, and there ...Author: Pooya Davoodi, Lai Yeng Lee, Qingxing Xu, Vishnu Sunil, Yajuan Sun, Siowling Soh, Chi-Hwa Wang

Apr 21, 2018 · Polymer membrane permeation- controlled drug delivery In this type, drug is totally or partially encapsulated within drug reservoir. Its drug release surface is covered by a rate-controlling polymeric membrane having a specific permeability. Drug reservoir may exist in solid, suspension or solution form. polymeric membrane can be fabricated from a nonporous (homogeneous or …

Transdermal devices were fabricated by adhesive sealing techniques. In vitro drug release studies were carried out using modified Franz diffusion cells. Drug release was found to depend on the type of membrane used to control the drug delivery, suggesting that drug delivery is efficiently controlled by the rate-controlling membranes.
