On Sunday, a judge signed search warrants to help determine whether drugs played a role in the death of the King of pop.
According to reports from the Los Angeles Times, police found numerous bottles of the drug inside Jackson's Los Angeles home - some full and some empty - prescribed by as many as five doctors to Jackson and his pseudonyms, quaoting unnamed law enforcement sources.
Authorities are investigating allegations that Jackson had been consuming painkillers, sedatives and antidepressants. The powerful sedative Diprivan, which is usually administered by anesthesiologists in hospitals, was found in his home.
It is not immediately clear what drugs if any were obtained from doctors.
According to Diprivan's manufacturer, AstraZeneca PLC, the medication is very strong and patients taking it should be constantly monitored.
