A 48-year-old man who was found dead under a bridge after taking painkillers and sleeping pills had an undiagnosed heart condition, an inquest heard.
Terence Ross Brailsford was discovered underneath a bridge near Newmanleys Road in Eastwood on October 2 last year.
Tests showed that Mr Brailsford, a student from Heanor, had taken a combination of Tramadol, a strong painkiller, and Zopiclone, a sleeping pill.
An inquest into his death was opened at Derby Coroners Court by assistant coroner Louise Pinder on May 31.
The hearing was told how a police investigation concluded there were no suspicious circumstances surrounding Mr Brailsford's death.
A toxicology report revealed he had taken prescribed medication within "the therapeutic range" shortly before he died, DerbyshireLive reports.
Miss Pinder said it "remains unclear" why Mr Brailsford, of Laceyfields Road, was under the bridge at the time.
His medical cause of death was listed as consumption of Tramadol and Zopiclone.
He also had a background of cardiomyopathy, a disease of the heart muscle, and asthma.
Depression also contributed to his death.
The coroner concluded that Mr Brailsford died as a result of the sedative effects of the therapeutic levels of prescribed medication against a background of significant undiagnosed heart disease and asthma.
