CAS#: 15272-69-2 (free base)

Description: Carcainium (free base) is phenylcarbamoylmethyl derivative with local anesthetic and potent anti-tussive activity. In preclinical studies Carcainium significantly reduced the spontaneous and histamine-evoked discharges in Aδ-fibres originating from airway, rapidly adapting stretch receptors (RARs) without affecting histamine-evoked bronchoconstriction. Acute pre-treatment of guinea-pigs with aerosols of Carcainium prevent of capsaicin-evoked and citric acid-induced coughs.
