Drug Delivery of Peptides: The Buccal Route [PDF]

, 1986
Peptides and proteins are currently emerging as a major class of future drugs. So far the research in this field is mainly focused on basic research covering isolation, synthesis, analysis, and biological and clinical effects. However, increasing attention is now also given to considerations regarding suitable dosage forms and routes of absorption.

Buccal drug delivery: A challenge already won?

Drug Discovery Today: Technologies, 2005
The main obstacles that drugs meet when administered via the buccal route derive from the limited absorption area and the barrier properties of the mucosa. The effective physiological removal mechanisms of the oral cavity that take the formulation away from the absorption site are the other obstacles that have to be considered.

Mucoadhesive polymers for buccal drug delivery

Drug Development and Industrial Pharmacy, 2014
Raising the concept of mucoadhesion in the 1980s, the use of mucoadhesive polymers for buccal drug delivery has been the subject of interest. Buccal route is one of the non-invasive routes comprising several advantages such as targeting the specific tissue (I), bypassing the first-pass effect (II) as well as higher patient compliance (III) and higher ...

Ketobemidone prodrugs for buccal delivery.

Acta pharmaceutica Nordica, 1991
Various carboxylic acid and carbonate esters of the opioid analgesic ketobemidone were prepared and assessed as potential prodrugs with the aim of obtaining a ketobemidone formulation suitable for buccal or sublingual absorption. The chemical stability, enzymatic hydrolysis and lipophilicity characteristics of the esters were studied using HPLC assay ...

Buccal/gingival drug delivery systems

Journal of Controlled Release, 1987
Abstract As a continuation of our previous work on oral mucosal adhesive tablets for the administration of insulin and for treatment of aphtous stomatitis, we have investigated a similar type of dosage form using hydroxypropyl cellulose, Carbopol and lidocaine of a model drug for the treatment of toothache by applying the system to the human gingiva.

Chemical Enhancers in Buccal and Sublingual Delivery

International Journal of Pharmaceutical Sciences and Nanotechnology, 2011
Rapid developments in the field of molecular biology and gene technology resulted in generation of many macromolecular drugs with superior pharmacological efficacy, site specificity and devoid of toxic effects. However, the major problem for the oral delivery of these therapeutic agents is their extensive presystemic metabolism, instability in acidic ...

Drug delivery via the buccal mucosa

Pharmaceutical Science & Technology Today, 1998
Abstract A candidate drug has entered the development phase but there are problems in drug delivery. The oral bioavailability is low or provides the wrong plasma profile. It is usual that other routes of administration are proposed such as nasal, pulmonary, transdermal, buccal or rectal drug delivery.

Double-phase hydrogel for buccal delivery of tramadol

Drug Development and Industrial Pharmacy, 2011
Treatment of chronic pain is complicated by the evidence that abuse of prescription opioids is rising; therefore, in many cases, chronic pain remains undertreated. Tramadol is an atypical central analgesic with a mixed mechanism of action offering many advantages over conventional opioids.We exploited the nonopioid action of tramadol, by bypassing the ...
