Heath Ledger dies at 28

Heath Ledger died from an accidental overdose of prescription medications including painkillers, anti-anxiety drugs and sleeping pills, the New York City medical examiner's office said Wednesday.

"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 short statement.

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

Hydrocodone and oxycodone are painkillers. Diazepam is an anti-anxiety drug commonly sold under the brand name Valium; alprazolam is also an anti-anxiety drug sold under such names as Xanax. Temazepam, sold under such names as Restoril and Euhypnos, is a sleeping agent. Doxylamine, an antihistamine, can be obtained over the counter as a sleep aid.
