Officials believe Carrie Fisher died from sleep apnea

She took medicine for the latter, which may have contributed to her death, said Todd Fisher.

"The manner of death has been ruled undetermined", the coroner's statement said.

Additional autopsy and toxicology details were not available.

Sleep apnea causes people to temporarily stop breathing while they sleep, for up to minutes at a time in extreme cases.

Fisher, 60, was taken ill on a flight to Los Angeles from London, where she was filming for British sitcom Catastrophe, in December.

The pair were laid to rest together in a cemetery in Hollywood Hills. He added that his family did not want a coroner's investigation of his sister's death.

"We're not enlightened. There's nothing about this that is enlightening".

He told Associated Press: "I would tell you, from my perspective, that there's certainly no news that Carrie did drugs".

Carrie Fisher (right) presents her mother, Debbie Reynolds, with the Screen Actors Guild life achievement award at the 21st annual Screen Actors Guild Awards in 2015. She noted in other interviews that she had used cocaine on the set of "The Empire Strikes Back", and struggled with addictions to prescription medication.

"I am not shocked that part of her health was affected by drugs", Todd Fisher said.

Todd Fisher said it was hard to blame doctors who treated his sister because they were trying to help her. "Can you really blame them?" he said. The examination by the Los Angeles County of Medical Examiner-Coroner also cited "multiple drug intake" and atherosclerotic heart disease, but did not specify further. She made her film debut as a teenager in 1975 comedy "Shampoo", two years before her breakthrough in the first "Star Wars" movie.
