The bodys conversion of Cyanocobalamin to Methylcobalamin is a metabolic process requiring energy, several biochemical steps, and can take up to 48 hours
The results are striking, but Lilly isnt quite done yet
developed mucus-penetrating nanoparticles that could rapidly penetrate the highly viscoelastic mucus layer, enabling drug delivery to previously unreachable tissue (Zhang et al., 2020)
For a 1 mg (1,000 mcg) target dose: Volume to Draw = Desired DoseConcentration = 1 mg5 mg/mL = 0.2 mL Convert to syringe units
Obviously, intravenous administration results in quicker and higher peak levels compared to oral delivery 28
Unlike the thousands of peptides naturally produced in the body, the synthetic peptide compounds are made in a lab, and are typically administered by injection
