The deadly cocktail of drugs, which apparently killed King of Pop Michael Jackson [Images], has finally been revealed.

The name of the painkillers emerged after police probing an injection, which apparently caused a cardiac arrest to the legendary star, talked to a doctor about the details.

And the doctor has revealed that Jacko, 50, was taking up to three powerful narcotic pain relievers at the same time -- when any more than one is considered potentially fatal, reports the Sun.

Sources close to the singer have revealed that he was injected three times a day with Demerol -- the painkiller given to him before his collapse at his LA home on Thursday.

He was also taking another painkiller, Dilaudid, and sources have said that he had recently been prescribed yet another narcotic pain reliever, Vicodin.

His other drugs included muscle relaxant Soma, a sedative called Xanax and anti-depressant Zoloft. He also took Paxil for anxiety and heartburn pill Prilosec.

On Friday, police were trying to establish who gave him his final injection.

According to celebrity website TMZ, a close member of Jackson's family said the daily dose of Demerol was "too much" and confirmed that the 11.30am shot caused his death.

Meanwhile, Los Angeles County Coroner Craig Harvey last night ruled out foul play.

However, he would not comment on specific drugs taken by Jacko until the results of tests in four to six weeks.
