Pentoxyverine is believed to suppress the cough reflex in the central nervous system, [1] but the exact mechanism of action is not known with certainty. The drug acts as an antagonist at muscarinic receptors [ 3 ] (subtype M 1 ) and as an agonist at sigma receptors (subtype σ 1 ) [ 6 ] with an IC 50 of 9 nM. [ 10 ]
