Molecular Weight: 296.84 Oxymetazoline HCl is an α1 and α2 adrenergic receptor agonist.

Biological Activity

Oxymetazoline hydrochloride is an α1 and α2 adrenergic receptor agonist. It is available over-the-counter as a topical decongestant in nasal sprays. The action of oxymetazoline results in vasoconstriction. In addition, the local application of the drug also results in vasoconstriction due to its action on endothelial postsynaptic α2 receptors; systemic application of α2 agonists, in contrast, causes vasodilation because of centrally-mediated inhibition of sympathetic tone via presynaptic α2 receptors.





Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)

Species	Baboon	Dog	Monkey	Rabbit	Guinea pig	Rat	Hamster	Mouse
Weight (kg)	12	10	3	1.8	0.4	0.15	0.08	0.02
Body Surface Area (m2)	0.6	0.5	0.24	0.15	0.05	0.025	0.02	0.007
Km factor	20	20	12	12	8	6	5	3

Animal A (mg/kg) = Animal B (mg/kg) multiplied by	Animal B Km
	Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×	mouse Km(3)	= 11.2 mg/kg
	rat Km(6)
