Isoxsuprine HCl

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

MedKoo CAT#: 531027

CAS#: 579-56-6 (HCl)

Description: Isoxsuprine is a beta 2-adrenergic agonist and NR2B subtype-selective N-methyl-D-aspartate (NMDA) receptor antagonist used for the treatment of pre-term labor and dysmenorrhea. Isoxsuprine affects the vascular smooth muscle and results in peripheral vascular dilation. Isoxsuprine also relaxes the uterine smooth muscles. Isoxsuprine elevated the blood flow volume in the umbilical arteries. Veterinary treatment of cows with isoxsuprine may temporarily lead to low levels of isoxsuprine in the hair of their newborn calves, which promotes growth.
