ASCOR vs NASCOBAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ascorbic acid (vitamin C) acts as an antioxidant and a cofactor for several enzymes involved in collagen synthesis, carnitine biosynthesis, and neurotransmitter synthesis. It facilitates iron absorption from the gastrointestinal tract and participates in immune function.
Vitamin B12 (cyanocobalamin) is a cofactor for methionine synthase and methylmalonyl-CoA mutase, essential for DNA synthesis, myelin formation, and hematopoiesis.
1 tablet (75 mg) orally once daily for antiplatelet effect; for acute coronary syndrome: initial dose 300 mg orally, then 75 mg orally once daily.
1 spray (500 mcg) intranasally once weekly.

Clinical Note
moderateAscorbic acid + Cyclosporine
"The serum concentration of Cyclosporine can be decreased when it is combined with Ascorbic acid."

"The serum concentration of Benzphetamine can be decreased when it is combined with Ascorbic acid."
Clinical Note
moderateAscorbic acid + Amphetamine
Terminal elimination half-life is 8-12 hours in patients with normal renal function; prolonged to 24-48 hours in renal impairment, requiring dose adjustment.
Approximately 6 days (depot effect due to slow release from injection site); for intramuscular doses, terminal elimination half-life is about 6 days due to gradual absorption
Renal: 70-90% (as unchanged drug and metabolites), biliary/fecal: minor (<10%)
Primarily renal (60-80% as unchanged drug), biliary/fecal (5-10%)
