McGuff Pharmaceuticals Inc., a wholly owned subsidiary of McGuff Company, Inc. announces the United States Food and Drug Administration’s New Drug Approval (NDA) of Ascor® (Ascorbic Acid Injection, USP)

Ascor® is provided in a 50 mL vial labeled as a Pharmacy Bulk Package with a strength of 500mg/mL.

Ascor® is vitamin C indicated for the short term (up to 1 week) treatment of scurvy in adult and pediatric patients age 5 months and older for whom oral administration is not possible, insufficient or contraindicated.

Important Safety Information

  • Ascorbic acid has been associated with development of acute or chronic oxalate nephropathy following prolonged use of high doses of ascorbic acid infusion. Patients with renal disease including renal impairment, history of oxalate kidney stones, geriatric patients, and pediatric patients less than 2 years old may be at increased risk.
  • Patients with glucose-6-phosphate dehydrogenase deficiency are at risk of severe hemolysis; a reduced dose is recommended.
  • Ascorbic acid may interfere with laboratory tests based on oxidation-reduction reactions, including blood and urine glucose testing.
  • Ascorbic acid may decrease the activities of erythromycin, kanamycin, streptomycin, doxycycline, and lincomycin. Bleomycin is inactivated in vitro by ascorbic acid.
  • Ascorbic acid may cause acidification of the urine and result in decreased amphetamine serum levels and affect excretion and plasma concentrations of other drugs sensitive to urine pH.

Ascor is the first single moiety ascorbic acid drug approved for the US market and is the result of a multi-year development effort.

Ronald McGuff, CEO said "The FDA approval of Ascor® Ascorbic Acid Injection USP will allow McGuff Pharmaceuticals, Inc. to deliver this medically necessary drug to US hospitals and pharmacies to improve patient health.
