The drugs being administered to an imprisoned Arizona gunman are too strong, his lawyers argue.

Lawyers for Jared Lee Loughner, who killed six people during a shooting spree in Tucson back in January, argue that he is being given unnecessarily strong medications in prison, the Los Angeles Times reported.

The lawyers argued that since Loughner has not officially been tried he still retains the right to decide what drugs he can take, the LA Times reported.

Prosecutors disagreed, citing incidents they say prove Loughner, who was diagnosed with schizophrenia, is a danger to himself and to others, the Arizona Daily Star reported.

The case was presented at the federal appeals court on Tuesday.

A three-judge panel listened to 90 minutes of arguing but did not come to a ruling, The Arizona Republic reported.

Loughner killed six people, including a 9-year-old girl, and injured 13 others when he went on a shooting spree back in January. One of the injured people was Arizona representative Gabrielle Giffords, who was shot in the head but has been recovering.

He has more than 40 felony charges against him.
