Antares Pharma announced the launch of Xyosted (testosterone enanthate) Injection indicated for testosterone replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone.

Xyosted, an androgen, was approved by the Food and Drug Administration (FDA) in September 2018. It is intended for once-weekly subcutaneous (SC) injection via a single-dose, disposable QuickShot autoinjector.  

Xyosted carries a Boxed Warning describing blood pressure increases that can raise the risk for major cardiovascular events (MACE), including non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death. Due to this risk, Xyosted should only be used for the treatment of men with hypogonadal conditions associated with structural or genetic etiologies. Prior to starting Xyosted, the patient’s baseline cardiovascular risk should be considered and blood pressure should be adequately controlled.
