Abstract

The invention provides a drug combination for analgesia, anesthesia or drug rehabilitation. The drug combination is composed of a tetrodotoxin injection and an opioid medical injection which are packaged separately. The tetrodotoxin injection is composed of tetrodotoxin containing a buffer agent and a high penetrating agent for opening of the blood-brain barrier (BBB) or a BBB carrier. The opioid medical injection is a commercially available injection containing an opioid receptor stimulant. In the drug combination for analgesia, anesthesia or drug rehabilitation, the BBB-opening high penetrating agent or the BBB carrier can raise BBB permeability and bioavailability of tetrodotoxin and the opioid medicine, and tetrodotoxin has a synergistic effect of de-addiction and synergism. Through cooperation of the three drugs, the drug therapeutic effect can be enhanced, duration of drug effect is prolonged, dosage of the opioid medicine is reduced, and tolerance and dependency of the opioid medicine are decreased or eliminated.

Description

technical field [0001] The invention relates to a combined medicine for analgesia, anesthesia or drug withdrawal, and belongs to the technical field of medicine preparation. Background technique [0002] Tetrodotoxin, the drug name is Tetrodotoxin, English Tetrodotoxin, referred to as TTX. Tetrodotoxin is a biologically active substance extracted from puffer fish viscera, which belongs to non-protein marine toxins, with a molecular formula of C11H17N3O8 and a molecular weight of 319.28. The appearance of tetrodotoxin is powdery crystal, insoluble in organic solvents, slightly soluble in water and ethanol, easily soluble in acidic aqueous solution, and decomposes rapidly in strong alkali or strong acid. Tetrodotoxin is relatively stable to heat, but it will gradually decompose when heated to 220°C, and it will be charred quickly when it exceeds 220°C. [0003] Studies have shown that the medicinal mechanism of tetrodotoxin lies in its ability to selectively block the nerve ...
