Abstract

The present invention discloses a transdermal delivery based pharmaceutical composition. The composition comprises a compound as shown in a formula (I) or pharmaceutically acceptable salt thereof, a macromolecular dispersing carrier material, a hot melting protecting agent and an optional fluxing agent. A preparation method of the transdermal delivery based pharmaceutical composition comprises thesteps of micronizing the compound as shown in the formula (I) or the pharmaceutically acceptable salt thereof, the macromolecular dispersing carrier material and the hot melting protecting agent, optionally adding the fluxing agent, mixing the components uniformly, and performing hot melting extrusion and micronizing to obtain microparticles of the compound as shown in the formula (I) or the pharmaceutically acceptable salt thereof. In addition, the invention provides an application of the pharmaceutical composition. The transdermal delivery based pharmaceutical composition can enable the compound as shown in the formula (I) to be quickly absorbed, so that the purpose of calming before anesthesia is achieved, breathing is not affected, and the adverse psychological effects on children dueto intramuscular injection or intravenous injection are avoided. Meanwhile, the pharmaceutical composition also can be used for preventing and/or treating hyperactivity.

Description

technical field [0001] The present invention relates to pharmaceutical preparation technology, and more particularly to a pharmaceutical composition for transdermal administration of a compound represented by formula (I) and a preparation method and application thereof. Background technique [0002] Ketamine (the corresponding racemic mixture of the dextro- and levo-enantiomers) is an N-methyl-D-aspartate (NMDA) receptor antagonist that produces a wide range of effects in humans, including sedation Pain, anesthesia, hallucinations, dissociative effects, elevated blood pressure and bronchiectasis. Ketamine is primarily used to induce and maintain general anesthesia. Other uses include sedation in intensive care, analgesia (particularly in emergency medicine), and treatment of bronchospasm. D-ketamine enantiomer (or S-(+) ketamine or esketamine) is a non-competitive and subtype non-selective activity-dependent NMDA receptor antagonist with a new and unique mechanism of actio...
