dyclonine hydrochloride, western medicine name. Commonly used dosage forms are mucilage agents. It is a local anesthetic. It is used for laryngeal anesthesia and lubrication during upper gastrointestinal endoscopy, and at the same time remove the foam in the cavity to make the field of vision clear.
Traits
dyclonine hydrochloride mucilage: after shaking well, it is a milky white viscous liquid with a slightly bitter and sour taste, a slight coolness, and a small amount of oil is allowed.
Indications
This product is used for laryngeal anesthesia and lubrication during upper gastrointestinal endoscopy, and at the same time remove the foam in the cavity to make the field of vision clear.
Piperidine hydrochloride is prepared by the reaction of piperidine and concentrated hydrochloric acid, and p-butoxyacetophenone and paraformaldehyde are added to it, and then concentrated hydrochloric acid is added as a catalyst to obtain crude dyclonine hydrochloride. The crude dyclonine hydrochloride is dissolved in absolute ethanol, activated carbon is added, heated and refluxed, filtered while hot, the filtrate is stirred and cooled, filtered, and vacuum dried to obtain dyclonine hydrochloride.
Local anesthetic | Duclonine hydrochloride (Dyclonine hydrochloride) is also known as dacolon, and its chemical name is 4-butoxy-β-piperidinyl phenylpropanone hydrochloride. It is a local anesthetic with fast onset, long action time, small adverse reactions and high safety. At present, dyclonine hydrochloride dosage forms that have been listed or reported in China mainly include ointment, cream, liniment, solution, gel and emulsion dosage form mucilage. Among them, the first five are mainly for external use, and the last one is for gastroscopy, digestive tract and other endoscopy. It is clinically used for mucosal surface anesthesia, skin analgesia and antipruritic. |
properties | white crystalline powder, slightly smelly, tattacky, slightly soluble in water, soluble in ethanol, acetone, chloroform and 60 ℃ water. Stable in the air, when heated, the decomposition solution becomes turbid and precipitates oil, and is stored in a closed and dark. |
pharmacodynamics | the mechanism of action is mainly nerve block, local anesthesia has fast effect, strong pharmacological effect and long duration, low toxicity, analgesic, antipruritic and bactericidal effects. Fig. 1 is dyclonine hydrochloride solution |
pharmacokinetics | injection is irritating, only used for appearance, and has strong penetration to mucosa. |
synthesis method | piperidine hydrochloride is prepared by reacting piperidine with concentrated hydrochloric acid, p-butoxyacetophenone and polyformaldehyde are added to it, and then concentrated hydrochloric acid is added as catalyst to obtain crude dyclonine hydrochloride. the crude dyclonine hydrochloride is dissolved in anhydrous ethanol, activated carbon is added, heated and refluxed, filtered while hot, the filtrate is stirred and cooled, and filtered, vacuum drying of dyclonine hydrochloride boutique. Fig. 2 shows the synthetic route of dyclonine hydrochloride |
