Ascorbic acid and calcium and sodium ascorbates are used as antoxidants in pharmaceutical manufacturing and in the food industry.
Sweetman SC (ed), Martindale: The Complete Drug Reference. London: Pharmaceutical Press (2009), p.1985.
In 20 patients in acute asthmatic crisis, 16 recovered promptly after receiving 6 g sodium ascorbate iv. Chronic oral treatment (0.6-1 g/day/60 days) with Na ascorbate prevented asthmatic symptoms in 18/25 asthmatic patients.

8 patients with hyphema were treated with iv glycerin in combination with sodium ascorbate. The results showed that glycerol in combination with sodium ascorbate diminished the hemorrhage in eye within 12-24 hr.

Each gram of sodium ascorbate contains approximately 5 mEq of sodium; this should be considered when the drug is used in patients on salt-restricted diets.

Antioxidants
Naturally occurring or synthetic substances that inhibit or retard oxidation reactions. They counteract the damaging effects of oxidation in animal tissues. (See all compounds classified as Antioxidants.)
Vitamins
Organic substances that are required in small amounts for maintenance and growth, but which cannot be manufactured by the human body. (See all compounds classified as Vitamins.)
Ascorbic acid, the reduced form of vitamin C, functions as a potent antioxidant as well as in cell differentiation. Ascorbate is taken up by mammalian cells through the specific sodium/ascorbate co-transporters SVCT1 and SVCT2. Although skeletal muscle contains about 50% of the whole-body vitamin C, the expression of SVCT transporters has not been clearly addressed in this tissue. ... This work ... analyzed the expression pattern of SVCT2 during embryonic myogenesis using the chick as model system. ... Immunohistochemical analyses showed that SVCT2 is preferentially expressed by type I slow-twitch muscle fibers throughout chick myogenesis as well as in post-natal skeletal muscles of several species, including human...

Humans use two sodium-ascorbate cotransporters (hSVCT1 and hSVCT2) for transporting the dietary essential micronutrient ascorbic acid, the reduced and active form of vitamin C. Although the human liver plays a pivotal role in regulating and maintaining vitamin C homeostasis, vitamin C transport physiology and regulation of the hSVCT systems in this organ have not been well defined. Thus, this research used a human hepatic cell line (HepG2), confirming certain results with primary human hepatocytes and determined the initial rate of ascorbic acid uptake to be Na(+) gradient, pH dependent, and saturable as a function of concentration over low and high micromolar ranges. Additionally, hSVCT2 protein and mRNA are expressed at higher levels in HepG2 cells and native human liver, and the cloned hSVCT2 promoter has more activity in HepG2 cells. Results using short interfering RNA suggest that in HepG2 cells, decreasing hSVCT2 message levels reduces the overall ascorbic acid uptake process more than decreasing hSVCT1 message levels. Activation of PKC intracellular regulatory pathways caused a downregulation in ascorbic acid uptake not mediated by a single predicted PKC-specific amino acid phosphorylation site in hSVCT1 or hSVCT2. However, PKC activation causes internalization of hSVCT1 but not hSVCT2. Examination of other intracellular regulatory pathways on ascorbic acid uptake determined that regulation also potentially occurs by PKA, PTK, and Ca(2+)/calmodulin, but not by nitric oxide-dependent pathways...

... Sodium ascorbate decreases cellular iron uptake by melanoma cells in a dose- and time-dependent fashion, indicating that intracellular iron levels may be a critical factor in sodium ascorbate-induced apoptosis. Indeed, sodium ascorbate-induced apoptosis is enhanced by the iron chelator, desferrioxamine (DFO) while it is inhibited by the iron donor, ferric ammonium citrate (FAC). Moreover, the inhibitory effects of sodium ascorbate on intracellular iron levels are blocked by addition of transferrin, suggesting that transferrin receptor (TfR) dependent pathway of iron uptake may be regulated by sodium ascorbate. Cells exposed to sodium ascorbate demonstrated down-regulation of TfR expression and this precedes sodium ascorbate-induced apoptosis. Taken together, sodium ascorbate-mediated apoptosis appears to be initiated by a reduction of TfR expression, resulting in a down-regulation of iron uptake followed by an induction of apoptosis...
