Matthew Perry‘s loved ones are getting some answers.
After initially deferring his cause of death pending a toxicology report, authorities have shared new information about the Friends star’s sudden passing on Oct. 28.
His cause of death was revealed as “the acute effects of ketamine,” the Los Angeles Counter Medical Examiner stated Dec. 15. His death was ruled an accident.
Other factors that contributed to Perry’s passing included drowning, coronary artery disease and the effects of buprenorphine, which is used to treat opioid use disorder, per the medical examiner.
Perry had taken ketamine infusion therapy—to treat depression and anxiety—over a week before he died, per the toxicology report obtained by TMZ Dec. 15. However, officials determined the drugs in his system at his time of death “could not be from that infusion therapy, since ketamine’s half-life is 3 to 4 hours, or less.”
Perry was found deceased at his home in Los Angeles on Oct. 28. He was 54.
