MedKoo Cat#: 525685 | Name: MK-467 HCl

Description:

WARNING: This product is for research use only, not for human or veterinary use.

MK-467 is a peripheral α2 -adrenoceptor antagonist. MK-467 dose-dependently attenuates the bradycardia associated with dexmedetomidine, and shortens the sedative effect without altering its quality. MK-467 may be useful in attenuating reductions in heart rates alongside dexmedetomidine.
