I suggest the (U.S.) National Library of Medicine's Hazardous Substances Data Bank (HSDB) as a starting point ( https://toxnet.nlm.nih.gov/newtoxnet/hsdb.htm ).. NLM's TOXLINE (with PubMed) is another database to consider ( https://toxnet.nlm.nih.gov/newtoxnet/toxline.htm )..
Dr Pertti, I couldn't find the subacute, subchronic studies there which I need to identify adverse effects after repeated exposures, and organ toxicity.
Please send me an email ( [email protected] ) with one or more examples of the drugs that you are interested in for acute, subacute, subchronic... data. Thank you.
