Sample Use Guides

In Vivo Use Guide
Canine seizure model: from 2 to 15 h following a single 3 mg/kg oral ameltolide dose the mean probability of obtaining a 1 unit reduction in the seizure clinical score severity was greater than 0.80.
Route of Administration: Oral
In Vitro Use Guide
As a function of increasing concentration, ameltolide produced a selective decrease in the afterpotentials of the spontaneous bursts before decreasing the frequency of bursts. The concentration estimated to inhibit the number of afterpotentials per burst by 50% (IC50 value) was 2.7 uM, whereas the ICs0 value estimated to reduce the frequency of bursts was 15 uM.
