Characterization of Cyanocobalamin in Healthy Voluteers After Intranasal and Intramuscual Administration
An Open, Randomized, Single-dose, Two-way Crossover Study to Characterize the Pharmacokinetic Properties of Cyanocobalamin When Administered as an Intranasal Spray and an Intramuscular Injection to Healthy Volunteers

The main purpose of this study is to assess the relative bioavailability of Nascobal Nasal Spray as compared to an IM injection of cyanocobalamin (European reference product).

This is an open-label, randomized, single-dose, two-way crossover study. The study consists of a screening visit, two 4-days confinement periods and a follow-up telephone call. The two confinement periods will be separated by a washout period of at least 28 days.
