Scrofula, you of all people should know that T1/2 and duration of action are 2 completely things... Clonazepam is the longest benzodiazepine you are likely to get scripted, as it's poor solubility allows it to renter the brain as it is slowly metabolized(nordazepam lasts longer than DZp Itself, not as long as CZP in general and certainly not for me, though with large doses it may build up
Nordazepam is available, and seems to be used more now, though in the form is Tranxene, which is pretty much completely converted to nordazepam in the stomach/go tract; and guess what? They were giving it to me 4 times a day, and that still didn't work, it was a disaster(another story for another time)
It has to do w/ lipophillicy, primarily. Dzp is so lipophillic it is rapidly absorbed and quickly enters the CNS; the father a drug enters, the faster it exits. It is distributed to adipose tissue, and is even stored in the heart
Loraepam lasts longer than a single dose of diazepam, and prevents seizures longer, this is a simple fact, and why hospitals have changed to Lorazepam as the go-to abti-epilipectic; of all people, Lorne here would know
and multiple studies again confirm the BA% of oxy, one put it a little less than 50%, one a little more, and another 70-80%, intranasal for snorting well ground oxycontin tablets(old school, not OP's)
Will repost more references, Backfromthebrink, though w/ all due respect, do NOT claim am stating an opinion when am stating irrefutable fucking facts
(second part was for Backfromthebrink, who seems cool, though he effectively insulted me; 15 minutes of reasearch would explain why diazepam is either given as an infusion, or every 2 hours, and why it isn't prescribed in favor of more effective (and newer) longer lasting benzodiazepines
