Fentanyl FENTORA (fentanyl buccal tablet) is a potent opioid analgesic, intended for buccal mucosal administration.
Fentanyl FENTORA is designed to be placed and retained within the buccal cavity for a period sufficient to allow the disintegration of the tablet and absorption of fentanyl across the oral mucosa.
Fentanyl FENTORA employs the OraVescent® drug delivery technology, which generates a reaction that releases carbon dioxide when the tablet comes in contact with saliva. It is believed that transient pH changes accompanying the reaction may optimize dissolution (at a lower pH) and membrane permeation (at a higher pH) of fentanyl through the buccal mucosa.
Active Ingredient: Fentanyl citrate, USP is N-(1-Phenethyl-4piperidyl) propionamide citrate (1:1). Fentanyl is a highly lipophilic compound (octanol-water partition coefficient at pH 7.4 is 816:1) that is freely soluble in organic solvents and sparingly soluble in water (1:40). The molecular weight of the free base is 336.5 (the citrate salt is 528.6). The pKa of the tertiary nitrogens are 7.3 and 8.4. The compound has the following structural formula:
