Drug Information
The following information is obtained from various newswires, published
medical journal articles, and medical conference presentations.
Company: Questcor Pharmaceuticals
Approval Status: Approved November 1996
Treatment Area: vitamin B-12 deficiency
Nascobal (TM) (Cyanocobalamin, USP) Gel for Intranasal
Administration has been approved as therapy for vitamin B-12
deficiency, including pernicious anemia, a disorder associated with
increased morbidity and mortality when untreated. Subjects
requiring more than the normal amount of vitamin B-12 due to
pregnancy, hepatic or renal disease can also be treated with
Nascobal.
Nascobal is a self-administered nasal gel. The recommended dose
of Nascobal in subjects with vitamin B-12 malabsorption who are in
remission following injectable B-12 therapy is 500 mcg/0.ImL
administered intranasally once weekly. It is recommended that
subjects treated with Nascobal be monitored at one month after
start of treatment, and then at intervals of three to six months to
insure adequate levels of vitamin B-12. The vitamin is effectively
absorbed through the nasal mucosa, resulting in therapeutic blood
levels being maintained throughout the course of treatment. The
product will be available as a metered-dose gel in 5mL bottles at a
dosage strength of 500 mcg/0.ImL.
Vitamin B-12 deficiency has a number of causes, including
malabsorption of vitamin B-12 resulting from structural or
functional damage to the gastrointestinal system and dietary
deficiency of vitamin B-12 in strict vegetarians. It is estimated
that one percent of the US population, or 2,750,000 people, will
develop pernicious anemia in their lifetime. It is further
estimated that over eight million vitamin B-12 injections are
administered in the United States each year.
Vitamin B-12 deficiency is found in up to ten percent of
patients over 60 years old. Current maintenance treatment calls for
injections of Vitamin B-12, once per month for life. This chronic
need for vitamin B-12 replacement therapy often requires frequent
trips to a health care professional’s office or visit by a home
health care professional to receive injections
