Is klonopin (clonazepam) more potient than valium, 4 myclonic seizures?

Klonopin (clonazepam) more potent. If potency is defined as effect per mg. More importantly, Klonopin (clonazepam) has longer duration of action, which is generally means better coverage for seizure control.
One or other. I have usually started with klonopin, (clonazepam) but resistance may develop or excessive saliva develop. A change to valium may help to recover effect and decrease saliva. Sedation may be a side effect of either, but my experience is that valium is better tolerated over long term.
