The drug DEXCOPHAN COUGH contains a combination of these active pharmaceutical ingredients (APIs):
|
1
Demorphan
UNII 9D2RTI9KYH - DEXTROMETHORPHAN HYDROBROMIDE
|
|
Dextromethorphan is a non-opioid antitussive drug. The major metabolite of dextromethorphan, dextrorphan, binds with high affinity to σ-receptors to produce its antitussive activity without exhibiting the classic opiate effects that occur from binding into μ- and δ-receptors. In larger than therapeutic doses, dextrorphan is also an antagonist of N-methyl-D-aspartate (NMDA) receptors. |

2
Ephedrine
UNII NLJ6390P1Z - EPHEDRINE HYDROCHLORIDE
|
|
Ephedrine is a sympathomimetic amine acting directly on the alpha and beta receptors and indirectly by increasing the release of noradrenaline by the sympathetic nerve endings. As with any sympathomimetic agent, ephedrine stimulates the central nervous system, the cardiovascular system, the respiratory system, and the sphincters of the digestive and urinary systems. |
