The fresh buccal mucosa is tied on the glass slide, and a mucoadhesive patch is wetted with 1 drop of phosphate buffer pH 6.

Sustained release of drugs from ethylcellulose- polyethylene glycol patches and kinetics of drug release. Dearden and Tomlison pointed out that salivary secretion alters the buccal absorption kinetics from drug solution by changing the concentration of drug in the mouth Buccalbioadhesive films, releasing topical drugs in the oral cavity at a slow and predetermined rate, provide distinct advantages over traditional dosage forms for treatment of many diseases.

Well defined bioadhesion is the ability of a material synthetic or biological to adhere to a biological tissue for an extended period of time. The weight, in grams, required to detach the patch from the mucosal surface provided the measure of mucoadhesive strength 29, 30, 31 Figure 1.

Because the medication absorbs quickly, these types of administration can be important during emergencies when you need the drug to work right away, such as during a heart attack.

There, drugs can be absorbed directly into the bloodstream without going through your digestive system. Design development and in vitro evaluation of bioadhesive dosage form for buccal route.

However, buccal patch offer greater flexibility and comfort than the other devices. Fresh buccal mucosa is mounted between the donor and receptor compartments. J Control Rel ; Mechanisms, barriers and pathways of oral mucosal drug permeation.

Sublingual and Buccal Medication Administration

Buccal Drug Delivery System: The glass slide is then put in the beaker, which is filled with ml of the phosphate buffer pH 6. Design and characterization of mucoadhesive buccal patches of diclofenac sodium. Int J Pharm Sci Res. Measurement of mechanical properties: Current Drug Del ; 4: The buccal patch is placed with the core facing the mucosa and the compartments clamped together.

After the mixing process, the resultant material is rolled on a release liner until the desired thickness is achieved. Menthol, vanillin, clove oil, etc. The novel buccal dosage forms exhibits better patient compliance 8. The minor salivary glands are located in epithelial or deep epithelial region of buccal mucosa.Limitations in buccal patches: The area of absorptive membrane is relatively smaller.

If the effective area for absorption is dictated by the dimensions of a delivery system, this area then becomes even smaller. The area of absorptive membrane is relatively.

Sublingual and buccal medication administration are ways to take certain oral drugs. Learn the differences, pros, cons, and considerations for each. Thesis, University buccal patches thesis of.
