first-ever oral replacement for vitamin B12 injections Cobacan? is expected to be the first and only drug suitable for completely replacing vitamin B12 injections. Cobacan? is a cherry-flavored sublingual lozenge formulated to dissolve in five to seven minutes. Cobacan not only gets cobalamin levels up as fast as injections, but it maintains those levels longer. Cobacan?, by generating cobalamin serum levels that cannot be achieved with any currently available supplements or drugs, will be the only substitute for painful and invasive IM injections of cobalamin. Cobacan? NDA expected for Q3, 2014.
