Example Embodiment

[0019] Example 1

[0020] This example is an example of tetrodotoxin purification.

[0021] Separate, extract and purify tetrodotoxin according to the following methods and steps:

[0022] 1. Take 10kg of puffer fish innards and ovaries, place them in a 50-liter stainless steel automatic homogenizer, stir the homogenate, centrifuge the homogenate in a centrifuge at a speed of 2000 rpm, and take the supernatant;

[0023] 2. Place the supernatant obtained in step 1 in a distillation vessel, control the vacuum degree to be not less than 0.1Pa, and perform vacuum distillation, and distill until it evaporates to dryness to obtain a solid;

[0024] 3. Dissolve 100 g of the solid obtained in step 2 in 500 mL of 30% (W%) acetic acid aqueous solution, add 95% ethanol to dilute to 75% alcohol, then filter and collect the filtrate;

[0025] 4. The filtrate in step 3 is distilled under reduced pressure in a distillation vessel, and the vacuum is controlled to be not less than 0.1Pa, and disti...

Example Embodiment

[0029] Example 2

[0030] This embodiment is an example of the agent of the present invention.

[0031] Accurately weigh 1 mg of pure tetrodotoxin in Example 1, dissolve it in 500 mL of 1% citric acid aqueous solution, dilute to 10,000 mL with distilled water, and mix well. At this time, the PH value of the drug is 6.0, which contains 0.1 μg / mL tetrodotoxin and 0.5 μg / mL citric acid.

[0032] The above-mentioned drugs were sterilized under cobalt irradiation for 10 minutes, and then bottled and sealed to prepare injections.

Example Embodiment

[0033] Example 3

[0034] This embodiment is another example of the agent of the present invention.

[0035] Accurately weigh 1 mg of pure tetrodotoxin in Example 1, dissolve it in 50 mL of 10% citric acid aqueous solution, and mix well. At this time, the PH value of the drug is 4.5, which contains 20μg / mL tetrodotoxin and 100μg / mL citric acid.

[0036] The above-mentioned drugs were sterilized under cobalt irradiation for 10 minutes, and then bottled and sealed to prepare injections.

Abstract

The invention relates to a drug rehabilitation and analgetic medicine and method for making the same, which comprises spheroidine, citric acid and distilled water. The medicine is highly effective, no drug dependency will be produced, no repetition will occur after ceasing application, so its adaptation human populations are wide.

Description

technical field [0001] The invention relates to a medicament for detoxification and analgesia, in particular to a medicament for detoxification and analgesia containing tetrodotoxin, and also relates to a preparation method of the medicament. Background technique [0002] Drug abuse, especially drug abuse, seriously endangers people's physical and mental health. The main drug they take is heroin. Heroin is a refined product of morphine, which is made by acylation of morphine. The traditional drug treatment of opioid dependent patients is a gradual drug withdrawal plan to eliminate the patient's physical dependence, in which opioid drugs with less dependence are used to replace those with strong dependence, which is the so-called decreasing substitution method. Methadone is a better alternative drug. It is an opioid receptor agonist. Because it lasts for a long time, the withdrawal symptoms are mild and short, and can completely relieve the withdrawal symptoms caused by morph...
