Abstract

An oral pharmaceutical composition with greatly increased bioavailability includes an oily agent, an effective amount of a nalbuphine ester prodrug or a pharmaceutically acceptable salt thereof. Such a pharmaceutical composition can greatly increase the oral bioavailability of nalbuphine for more than 12 times and prolong the retention time of nalbuphine in a body, thereby maintaining a longer analgestic period of time, as well as reducing the analgestic cost.

[Background of the present invention] nalbuphine is an affinity agent having both the opioid receptor affinity and antagonistic effects. These drugs improve the serious shortcomings of the original addictive analgesics, such as greatly reducing their addictive and additive properties, and reducing their respiratory depression. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs (please read the notes on the back before filling this page) The oral bioavailability of traditional nalbuphine-HC1 is less than 5%. Therefore, at present, Nabufurin (1 ^ 丨 13111311 丨 116-] ^ (:: 1) has not been marketed as an oral dosage form. In response to this shortcoming, Harrelsnj · dWng y Y. J. in his 1988 paper, Use acetylsaHcylate ester prodrug to increase the oral absorption of naibuphine-HCl and improve the bitterness of nalbuphine-HCl. Acetylsalicylate ester prodrug can increase the oral bioavailability by about 5 times ( (From 5% to 16%), but it is still not practical for oral use. In addition, in a paper published by Hussain Μ · Α · et al. In 1988, opiates could be delivered by buccal delivery (buccal delivery). The bioavailability of prodrugs is increased to 35% to 50%. However, intrabuccal administration is not as convenient as oral administration, and patient acceptance is not as good as oral administration. Therefore, a high bioavailability is urgently needed.
