Emergent BioSolutions acquires US and Canadian rights to Hikma’s Kloxxado naloxone nasal spray

Emergent BioSolutions announced that it has signed an agreement to acquire marketing rights to Hikma Pharmaceuticals’ Kloxxado naloxone nasal spray in the US and Canada. Kloxxado, which delivers an 8 mg dose, was approved by the FDA for the reversal of opioid overdose in September 2021. Emergent previously acquired Narcan nasal spray, which delivers a 4 mg dose of naloxone, in 2018 when it acquired Adapt Pharma.

Kloxxado is available by prescription only; Narcan has been approved for over-the-counter sales since March 2023. According to the announcement, Hikma will continue to manufacture Kloxxado, and Emergent will distribute the nasal spray directly to qualified organizations through a web site.

Emergent President and CEO Joe Papa commented, “Meeting the needs of our patients and customers by now offering two nasal naloxone products at different strengths – Narcan Nasal Spray 4 mg and Kloxxado Nasal Spray 8 mg – allows Emergent to do its part to help save lives from this devastating crisis.”
