Abstract

The invention discloses a fentanyl double-layer buccal tablet and a preparation method thereof. The buccal tablet is composed by a quick release layer (an outer layer) and a sustained release layer (an inner layer) which form a biphasic drug release system. The quick release layer is prepared by effervescence and cyclodextrin inclusion technologies, a transient change of a pH value happens around the tablet by utilizing an effervescence reaction, and the quick release layer rapidly disintegrates and releases fentanyl in a few minutes; the sustained release layer slowly releases drugs to maintain an effective plasma concentration for up to a few hours. The buccal tablet releases the drugs from fast to slow, maintains the effective plasma concentration for a long time, is easy to use, is safe and reliable, and has the characteristics of rapid and continuous analgesia.

Description

technical field [0001] The invention belongs to the technical field of analgesics, and relates to a fentanyl double-layer buccal tablet and a preparation method thereof. Background technique [0002] Pain is one of the most common and direct body damages caused by injuries and weapons of war, which seriously affects the quality of life of patients. As a highly selective μ opioid receptor agonist, fentanyl has an analgesic effect 100 times that of morphine. It is less addictive, has a fast onset of action, and easily penetrates the blood-brain barrier. Pain and other sharp pains. About 80% of fentanyl is metabolized within 30 minutes after injection, and repeated administration is required to maintain effective blood drug concentration; while skin patches release slowly and take effect after 20-48 hours, suitable for chronic dull pain treatment . [0003] The fentanyl oromucosal administration preparation (trade name: ACTIQ) launched by Cephalon Corporation of the United S...
