Levodropropizine is a cough suppressant. It is the levo isomer of dropropizine. It acts as a peripheral antitussive, with no action in the central nervous system.[1] It does not cause side effects such as constipation or respiratory depression which can be produced by opioid antitussives such as codeine and its derivatives.
