- Autopsy results into the death of actor Mathew Perry have been released.
- The 54-year-old was found lifeless in the pool of his LA home on October 28.
- The death has been ruled an accident.
Matthew Perry died from the acute effects of the anaesthetic ketamine, according to the results of an autopsy on the 54-year-old Friends star.
The Los Angeles County Department of Medical Examiner said in the autopsy report released on Friday that Perry also drowned in "the heated end of his pool", but that it was a secondary factor in his October 28 death, which was deemed an accident.
"The manner of death is accident," the report said.
The report says coronary artery disease and buprenorphine, which is used to treat opioid use disorder, also contributed.
Perry was declared dead after being found unresponsive at his home in the Pacific Palisades area of Los Angeles.
Investigators performed the autopsy the following day.
The actor, who played Chandler Bing in the hit US sitcom Friends, had taken drugs in the past but had been "reportedly clean for 19 months", according to the report.
The coroner said he was reported to have been having ketamine infusion therapy to deal with depression and anxiety, and his last treatment was one-and-a-half weeks before his death.

The assistant told investigators Perry had not been sick, had not made any health complaints, and had not shown evidence of recent alcohol or drug use.
Perry was open about discussing his struggles with addiction dating to his time on Friends in the 1990s.
"I loved everything about the show but I was struggling with my addictions which only added to my sense of shame," he wrote in his 2022 memoir.
"I had a secret and no one could know."
Following his death, a foundation was set up in his name to help those struggling with addiction.
