Research Overview

IFN-alpha-2b

Extensively studied recombinant type I interferon with direct antiviral and immunoregulatory effects. Clinical literature spans hepatitis treatment, antiviral research, and immune-oncology contexts.

Pidotimod

Pidotimod has human data in recurrent infections, especially where immune stimulation or reduced infection frequency is the target. Published work commonly reports improvements in phagocyte function, mucosal defense, and fewer respiratory infection episodes.
