The present invention relates to parenteral and enteral multivitamin preparations to be administered in liquid form and representing a reduced source of peroxides. Peroxide generation in multivitamin preparations is believed to be due to the interaction of riboflavin and ascorbate in the presence of light. More specifically the present invention relates to parenteral and enteral multivitamin preparations to be administered in liquid form and comprising two distinct phases in order to keep the riboflavin separate from the ascorbate up to a molar ratio of no more than 1:10,000 between the riboflavin and ascorbate concentrations until the time of parenteral or enteral administration.

Why it's free to use
- Filed April 15, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 15, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 15, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
