Stockholm, Sweden — Medivir AB (OMX: MVIR) announces that Adasuve now will be launched for the treatment of mild to moderate agitation of patients with schizophrenia or bipolar disorder. Medivir entered a license and distribution agreement for the commercialization of Adasuve with Ferrer in September 2013. Adasuve is a brand new inhalable treatment of agitation and is approved by EMA (European Medicines Agency) for sale in Europe.

“It is gratifying to be able to launch Adasuve in the four main Nordic countries as a complement to our existing product portfolio” comments Henrik Krook EVP Commercial, Medivir.

About agitation
More than eight million of the European adult population lives with schizophrenia and bipolar disorder. Market research in the European territory indicates that 15-20 percent of those with schizophrenia and bipolar disorder experience an average of two episodes of agitation each year. The goal of treatment of agitation is to help the patient to gain control of their emotions or anxiety, and to avoid enforcement action that might otherwise have to be used to manage the patient's condition. The standard treatment for acute agitation today consists of antipsychotic drugs, sometimes in combination with benzodiazepines.

About Adasuve
Adasuve is the first inhalable drug in psychiatry. Adasuve is a non-invasive, fast acting alternative to currently used therapies. Because of its non-invasive form of treatment Adasuve can bring benefits to both patients and caregivers. Adasuve combines the proprietary Staccato system with loxapine, an antipsychotic medicinal product. The Staccato system is a hand-held inhaler that delivers a drug aerosol to the deep lung resulting in intravenous-like pharmacokinetics and rapid systemic effects.
