Hemicholinium-3 is a drug which blocks the reuptake of choline by the high affinity transporter ChT at the presynapse. The reuptake of choline is the rate limiting step in the synthesis of acetylcholine; hence, hemicholinium decreases the synthesis of acetylcholine. It is therefore classified as an acetylcholine antagonist.
