Problems solved by technology

After repeated use, tolerance will become stronger and stronger, resulting in a vicious circle, leading to serious drug addiction. Therefore, this type of drug has always been strictly controlled as a drug
Concomitant use of other medications to reduce tolerance and dependence on opioids has long been attempted, but so far without success

Abstract

The invention relates to an oil-phase preparation for opiates medicaments and a preparation method thereof. The preparation is oral administration oil prepared by fully dissolving the opiates medicaments into medical or edible oil. By changing the formulations and the administration mode of the opiates medicaments, the dependency and tolerance of the opiates medicaments are controlled effectively. The oil-phase preparation is used for easing pain, and can reduce the using dose of the opiates medicaments, prolong the analgesis time, improve the analgesis effect and reduce or eliminate the tolerance, dependency and the toxic and side effect of the opiates medicaments.

Description

technical field [0001] The invention relates to an opioid drug oil-phase preparation and a preparation method thereof, belonging to the technical field of pharmaceutical preparation. Background technique [0002] Pain is the most widespread disease worldwide. According to reports, 1 billion people are in pain every day in the world, and about 1 / 3 of people in our country have experienced chronic pain in the course of their lives. With the quickening pace of life, the incidence of various pains is increasing dramatically. [0003] Currently, the most used analgesics in the world are opioids, including: morphine, pethidine, methadone, fentanyl, codeine, tramadol, dihydroetorphine, buprenorphine, Tazocine, bupivacaine, analgesic new and so on. Although these drugs act quickly and have strong analgesic efficacy, the analgesic time is short, generally only 2 hours, and they all have tolerance, dependence and toxic side effects. After repeated use, the tolerance will become st...
