Furthermore, after absorption from the gastrointestinal tract, such drugs must pass to the liver, where they may be extensively altered; this is known as the first pass effect of drug metabolism. Due to the digestive activity of the stomach and intestines, the oral route is unsuitable for certain substances, such as salvinorin A .
Sublingual administration (SL), dissolved under the tongue, but due to rapid absorption many consider SL a parenteral route; Oral (PO), swallowed tablet, capsule or liquid; Enteral medications come in various forms, including [3] oral solid dosage (OSD) forms: [4] Tablets to swallow, chew or dissolve in water or under the tongue
The sublingua is found on the underside of the primary tongue in tarsiers, lemuriform primates, and some other mammals. The sublingua ("under-tongue") is a muscular secondary tongue found below the primary tongue in tarsiers and living strepsirrhine primates, which includes lemurs and lorisoids (collectively called "lemuriforms").
The tongue is used to roll food particles into a bolus before being transported down the esophagus through peristalsis. The sublingual region underneath the front of the tongue is a location where the oral mucosa is very thin, and underlain by a plexus of veins. This is an ideal location for introducing certain medications to the body.
The heterogeneous family of proline-rich, human salivary glycoproteins, such as PRB1 and PRH1, are salivary gland-specific proteins with highest level of expression. Examples of other specifically expressed proteins include the digestive amylase enzyme AMY1A , the mucin MUC7 and statherin , all of major importance for specific characteristics ...
Thin-film drug delivery uses a dissolving film or oral drug strip to administer drugs via absorption in the mouth (buccally or sublingually) and/or via the small intestines (enterically). A film is prepared using hydrophilic polymers that rapidly dissolves on the tongue or buccal cavity, delivering the drug to the systemic circulation via ...
