Hi bpeck,I found the same 67% biliary excretion figure in a search I just did on rocephin. I thought it was higher than 67%, however, even one percent of a seriously hepatotoxic compund eliminated via the biliary route can cause liver disease.
My understanding is that what's important is HOW rocephin behaves during elimination more than HOW MUCH leaves via what route.

Interestingly, the above links claim 60-70% RENAL elimination as unchanged drug.
Dr. B. related to me when I saw him that he's had his gallbladder removed due to rocephin. Rocephin is a life-saver, fantastic for huge numbers, however, the cost/benefit calculus entailed by ALL of it's effects ought to be included in any decision made by any patient considering it.
I posted over a year ago on the importance of keeping your gallbladder when many people were discussing rocephin and their upcomming gallbladder resections.
I have tried Zith a few times. It has caused symptoms that have led to discontinuation, but at other times it's been ok, not super, but fine.
Zith takes longer than many other meds to be excreted I've read. But I also think most other meds take much longer to excrete than what is generally stated in the literature.
Dr. K informed me of this longer duration to elimination and I've been on several homeopathic remedies to remove what's been left, even from meds I've taken over two years prior.
I'm unclear on the exact significance of this lingering, but the impression I've gotten is that it's not good. Anyhow, I believe Zith takes longer than many others.
The doc who prescribed the rocephin was Dr. H. He was aware of my stick of butter a day diet before he prescribed it and I expressed reluctance and concern to him. He went ahead anyway and for over a year afterward I experiened pain.
After my eighth dose of IV rocephin I discussed the pain with Dr. H. He expressed amazement and stated that he had never seen it happen so quickly.
How's your gallbladder doing currently?
