Subject: Contents of the lethal injection

Greetings Sir,
I was wondering if you can help me out with my search for my 
science assignment.  Well, this assignment started because of 
some guy being death sentenced at Jan 4. 1999, Philippines, and 
it was a big issue to us (as they say).  Can you tell me what are 
the contents of the lethal injection that they use during 
execution and what each compound (in the content) is used for?  
Thanks for answering the question, since I'm really having a 
difficult time finding it in newspapers.
