Heath Ledger died from an accidental acute intoxication of prescription medicine, the New York medical examiner has announced.

“Mr. Heath Ledger died as the result of acute intoxication by the combined effects of oxycodone, hydrocodone, diazepam, temazepam, alprazolam, and doxylamine,” the office said in a statement.

“We have concluded that the manner of death is accident, resulting from the abuse of prescription medications.”

Police found a handful of the aforementioned drugs at the Brokeback Mountain star’s apartment on the day of his death, Jan. 22. Alprazolam (Xanax), diazepam (Valium) and lorazepam (Ativan) are anti-anxiety medications. Other drugs found were sleeping aids zopiclone (Lunesta) and the sedative temazepam (Restoril).

The drugs are the generic names for the OxyContin painkiller, the anti-anxiety drug Valium, Xanax, an anti-anxiety drug, and the sleep aids Restoril and Unisom. Hydrocodone is another name for Vicodin, a painkiller.

An autopsy conducted on Jan. 23 proved to be inconclusive.

Following two L.A. memorial services, Heath is expected to be buried in his hometown of Perth, Australia this weekend.
