Hydroxypropyl beta-cyclodextrin (HP-β-CD) can be used as a carrier for central system drugs.
When intraocular administration of opiates to rats, HP-β-CD prolongs anesthesia time and reduces the occurrence of side effects on the spikes. The reason is that HP-β-CD is similar to a slow-release container, reducing free drug distributed from the cerebrospinal fluid into the blood. On the other hand, when HP-β-CD is injected into the brain of rats, it can quickly enter the circulatory system and finally be discharged through the urine.
