Rapid and Safe Correction of Vitamin B12 Deficiency using Novel Methylcobalamin Nasal Spray

Abstract

Background & Aims: Methylcobalamin nasal spray (NasoB12® ) has been developed to overcome the drawbacks of currently available therapeutic options like the poorly absorbed oral route and the painful intramuscular route. The present study was designed to evaluate the safety and efficacy of NasoB12® in patients with Vitamin B12 deficiency, with serum vitamin B12 (svB12) <200 pg/mL (148 pmol/L).
