Benzoctamine is a drug that possesses sedative and anxiolytic properties. It is different from most sedative drugs because in most clinical trials it does not produce respiratory depression, but actually stimulates the respiratory system. When co-administered with other drugs that cause respiratory depression, like morphine, it can cause increased respiratory depression. Peak effects are reached at about an hour, and effects wear off after about 2–3 hours. This drug is also used as a sedative in the hospital scene in patients who have respiratory failure.

It appears to reduce turnover of serotonin.[1]

Its effects can be variable.[2]
