[Research progress on alkaloid monomer analgesic preparations].

ABSTRACT

Pain is one of the problems that seriously affect people's quality of life for thousands of years. The causes of pain are complex and varied,and long-term pain can also lead to depression. It has become a research hotspot to develop analgesic preparations with significant drug effects and small side effects. Recent studies have shown that certain alkaloid monomers have analgesic targets such as γ-aminobutyric acid,cannabinoids,and capsaicin. If their preparation is applied to the analgesic field,they can make up for the defects such as strong addiction and side effects of traditional opioid and non-steroidal analgesic drugs,but there is no relevant literature to summarize the research results in this field. This article first introduces the mechanism of pain production and the target of analgesia. Based on this,the application status of alkaloid monomer analgesic preparations approved by China Food and Drug Administration( CFDA)( number varieties,type of dosage form,drug description,analgesic mechanism and advantages) was analyzed,and the research dynamics of alkaloid monomer analgesic preparations( new formulation and new technology) were reviewed. Finally,some problems in this field were pointed out,such as imperfect medication information,inadequate transformation of research results,and too few kinds of analgesic components in developed alkaloids. The development direction was also pointed out for the above problems,with a view to provide reference for further development and in-depth research.
