Relationship btw 1/2 life and onset of action?

Posted by Janelle on April 5, 2002, at 2:04:32

I'm sorry to post this again, but I'm afraid it will get *lost* above because I mistakenly typed it in all caps and then a post appeared just below it in caps, making the two posts hard to distinguish.
Here's my question:
Is there a relationship between how long it takes a drug to start working (e.g. 2 hours after being taken) and that drug's half life?
Meaning do drugs that take less time to start working also have shorter half-lives? Conversely, do drugs that take longer to start working also have longer half lives?
thanks!
