Buccal absorption refers to the entire mucus membrane of the mouth, whereas sublingual absorption is specific to the heavily vascular area below the tongue, the most rapid and efficient area of administration through the mouth.
Buccal is pertaining to the cheek, so buccal medication is dissolved like a lozenge in the cheek.
the space between the teeth and the mucous mebrane lining the cheek is called the buccal sulcus.
Sublingual tablets dissolve under the tongue. Buccal tablets dissolve inside the cheek. Both allow medication to be absorbed directly into the bloodstream, bypassing the digestive system.
Drugs administered buccally and sublingually bypass the gastrointestinal tract and the first-pass metabolism in the liver, allowing for direct absorption into the bloodstream. This rapid absorption leads to quicker onset of therapeutic effects compared to orally administered drugs, which must first dissolve in the stomach and be absorbed through the intestines. Additionally, sublingual and buccal routes provide a larger surface area for absorption and often utilize mucosal membranes, facilitating faster drug delivery.
The teeth form the boundary between the buccal and lingual cavities.
Enteric-coated products, buccal tablets, sublingual tablets, carcinogenic products, tertogenic products, cytotoxics, and extended-release drugs cannot be crushed for enteral feeding.
The buccal route is a method of drug administration where medication is placed between the gums and the inner lining of the cheek, allowing for absorption through the mucous membranes in the mouth. This route bypasses the digestive system and liver metabolism, resulting in faster onset of action. It is commonly used for certain medications, such as those for pain management or hormone replacement therapy. Buccal administration can enhance bioavailability and provide a convenient alternative to oral or injectable routes.
Fentanyl nasal delivery is thru the nose and buccal tablets are placed between the gum and cheeck
between the gum and the cheek.
buccal
It is a process by which diffusible nutrients transfered from the gut into the blood or lymph by physico-chemical process and active transport. No absorption occurs in buccal cavity and very little absorption takes place in the stomach e.g. of alcohol. Particullarly all absorption takes place through the small intestine.
The word "buccal" refers to the facial cheeks.
