Kloxxado is an opioid antagonist that delivers 8 mg of naloxone hydrochloride per spray into the nasal cavity compared to the previously approved 2 mg and 4 mg naloxone nasal spray products currently on the market. Kloxxado is intended for immediate administration as emergency therapy in situations where opioids may be present.

In April 2021, the Food and Drug Administration (FDA) approved Kloxxado via the 505 (b) (2) pathway based on the safety and effectiveness of naloxone hydrochloride (Narcan injection).
