Can anybody tell me how could I obtain the LD50 of a drug in rats?
I know something about that, but I´d like a little help.
The LD50 could be between 5-10 mg/kg w.
How many animals per group?, Which should be the initial dose?, And the
last one?
Yours sincerely:
Dr. Francisco Rojas ( fcorojas at arrakis.es).
Thank you.
