the end of Ener-B Nasal Gel ("Ener-B"):
This Court referred to Judge Ross the issue of whether
Ener-B is a "food" or a "drug" within the meaning given to these terms
by the Federal Food, Drug and Cosmetic Act ("FDCA" or the "Act"),
21 U.S.C. §§ 301-395 (1988 & Supp. V 1993)
(unless otherwise indicated, all citations to the U.S.C.
are to the 1988 edition and 1993 volume supplement).
Judge Ross found that the Food and Drug Administration ("FDA")
reasonably determined that Ener-B was a drug
and not a "food" within the meaning of
sections 201(f) and 201(g)(1)(C) of the Act,
21 U.S.C. §§ 321(f) and 321(g)(1)(C).
The defendant markets Ener-B,
which is intended to be applied to the inside of one's nose.
As intended to be used, the vitamin B-12 contained in Ener-B
bypasses digestion through the gastrointestinal tract,
where it would be absorbed into the body through the intestines.
Instead, Ener-B's vitamin B-12 is absorbed directly
into the blood stream through the nasal mucosa.
On February 26, 1987, the FDA notified Nature's Bounty
that the FDA considered Ener-B to be a "drug" under the FDCA,
and that Ener-B was being marketed illegally
because it had not received recognition or approval
as a "new drug" under the Act.
The FDA also alleged that Ener-B was misbranded
and improperly labelled under the Act.
