Late Soundgarden singer Chris Cornell's doctor has denied he had anything to do with the rocker's tragic death in May 2017, claiming that Cornell was properly advised about the dangers of the anti-anxiety medication he was prescribed.

Dr. Robert Koblin responded to the lawsuit filed against him by Cornell's widow Vicky last November. Vicky sued the doctor for malpractice, accusing him of over-prescribing drugs that eventually caused her husband to commit suicide. Vicky and her two children, also named in the suit, are seeking unspecified damages. Koblin is asking that the wrongful death suit be dismissed.

Koblin has responded that Chris was “well aware” of the risks associated with taking the anti-anxiety meds, and has claimed that he's covered by a malpractice law that protects doctors when a death occurs as as result of a patient's ongoing disease or condition. The doctor added that he did everything in his professional capacity to help the singer, but that Chris also asked “not to be informed” of all the risks associated with taking anti-anxiety medication.

Vicky claims in the suit that Koblin prescribed 940 doses of the anti-anxiety drug Lorazepam, a.k.a. Ativan, as well as Oxycodone during the last 20 months of Chris's life, without examining him or doing anything else to determine if her husband was in danger. According to the suit, the use of Lorazepam, if not monitored, can increase the risk of suicide because it can impair the patient's judgment.

Chris was pronounced dead in the early morning hours of May 18th, 2017 after being found unresponsive in his Detroit hotel room following a Soundgarden show. The 52-year-old had sedatives and an anxiety drug in his system, but died by hanging himself. According to the medical examiner, the drugs didn't contribute to his death.
