Texcol-dm
Texcol-dm Uses, Dosage, Side Effects, Food Interaction and all others data.
Texcol-dm suppresses the cough reflex by a direct action on the cough center in the medulla of the brain. Texcol-dm shows high affinity binding to several regions of the brain, including the medullary cough center. This compound is an NMDA receptor antagonist and acts as a non-competitive channel blocker. It is one of the widely used antitussives, and is also used to study the involvement of glutamate receptors in neurotoxicity.
Texcol-dm is an opioid-like molecule indicated in combination with other medication in the treatment of coughs and pseudobulbar affect. It has a moderate therapeutic window, as intoxication can occur at higher doses. Texcol-dm has a moderate duration of action. Patients should be counselled regarding the risk of intoxication.
