Tetrahydropalmatine (DL-Tetrahydropalmatine) hydrochloride possesses analgesic effects. Tetrahydropalmatine hydrochloride acts through inhibition of amygdaloid release of dopamine to inhibit an epileptic attack in rats.
|Solubility (25°C)||DMSO 25 mg/mL
Water 4 mg/mL (ultrasonic and warming and heat to 60°C)
|Storage||2-8°C, protect from light, dry, sealed|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.
