Carbamazepine transbuccal delivery: the histo-morphological features of reconstituted human oral epithelium and buccal porcine mucosae in the transmu…
2009
Transbuccal drug delivery is an attractive way of administration since several well-known advantages are provided, especially with respect to peroral management. Carbamazepine (CBZ) is an anticonvulsant which is useful in controlling neuropathic pain, and it is currently administered by peroral route, although its absorption and bioavailability is limited due to various factors. The oral cavity could be an interesting site for transbuccal CBZ delivery due to two properties: slow administration of constant low drug doses and less dose-related side effects. However, in transbuccal absorption a major limitation could be the low permeability of the mucosa which results in low drug bioavailabil…
Human buccal mucosa as an innovative site of drug delivery.
2009
The authors review the ultra-structural aspects and permeability features of normal human oral mucosa, after having recently tested and used it as a new site of systemic drug delivery. The pertinent scientific literature from 1975 through 2009 has been analysed and discussed. Buccal epithelium is a relatively permeable, robust non-keratinized tissue and blood vessels drain directly into the jugular vein; due to its particular features, it has been of increasing interest to researchers as an alternative site of drug administration. The review describes the structure and function of the buccal mucosa, the rationale for transbuccal drug delivery and the main transmucosal drug delivery systems.…
