About RAPIVAB (peramivir injection)
RAPIVAB (peramivir injection) is an intravenous (I.V.) viral neuraminidase inhibitor for the treatment of acute uncomplicated influenza in patients 18 years and older who have been symptomatic for no more than two days. Efficacy of RAPIVAB is based on clinical trials of naturally occurring influenza in which the predominant influenza infections were influenza A virus; a limited number of subjects infected with influenza B virus were enrolled. The efficacy of RAPIVAB could not be established in patients with serious influenza requiring hospitalization. In clinical studies, side effects with RAPIVAB were similar to placebo. The most common adverse reaction was diarrhea (RAPIVAB 8% vs 7% placebo). Similar to other neuraminidase inhibitors, there is a risk of neuropsychiatric events (confusion, delirium) and serious skin reactions.

In August 2010, Green Cross Corporation announced that it had received marketing and manufacturing authorization for I.V. peramivir in Korea under the name PeramiFlu^®.
