A histopathology study on the effects of acute exposure of tropical analgesic spray on brain tissues of sprangue dawley rats

Topical analgesic sprays are a group of drugs that inhibits the action of pain receptors (nociceptors) resulting in a pain relieving effect. In Malaysia, the abuse of topical analgesic sprays via inhalation is now growing in popularity amongst teenagers as it causes a “high” effect and it is easil...
