Mequitamium iodide (LG 30435) is a quaternary ammonium phenothiazine. Mequitamium iodide was found to bind with high affinity only to histamine H1 receptors and to muscarinic acetylcholine receptors. The (+)-(S)-enantiomer is 10-fold more potent than (-)-(R)-enantiomer as a histamine antagonist, while the two enantiomers show the same antimuscarinic activity in vitro. In animal models, it exerts antiasthmatic and antiallergic properties. It was being clinically investigated as a treatment of asthma and rhinitis.
