5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Ascorbic acid (vitamin C), plain, ATC code: A11G A
Ascorbic acid (vitamin C) cannot be synthesised by man, therefore a dietary source is necessary.
Ascorbic acid (vitamin C) acts as a cofactor in numerous biological processes including the hydroxylation of proline to hydroxyproline. In deficiency, the formation of collagen is therefore impaired.
Ascorbic acid (vitamin C) is important in the hydroxylation of dopamine to noradrenaline and in hydroxylations occurring in steroid synthesis in the adrenals.
Ascorbic acid (vitamin C) is a reducing agent in tyrosine metabolism and by acting as an electron donor in the conversion of folic acid to tetrahydrofolic acid is directly involved in the synthesis of purine to thymine.
Ascorbic acid (vitamin C) is also necessary for the incorporation of iron into ferritin.
Ascorbic acid (vitamin C) increases the phagocytic function of leucocytes; it possesses anti-inflammatory activity and promotes wound healing.
Deficiency can produce scurvy. Features include swollen inflamed gums, petechial haemorrhages and subcutaneous bruising.
The deficiency of collagen leads to development of thin watery ground substances in which blood vessels are insecurely fixed and readily ruptured. The supportive components of bone and cartilage are also deficient causing bones to fracture easily and teeth to become loose. Anaemia commonly occurs probably due to the role of ascorbic acid (vitamin C) in iron metabolism.
5.2 Pharmacokinetic Properties
Ascorbic acid (vitamin C) is a water soluble vitamin which is readily absorbed from the gastro-intestinal tract and is widely distributed in the body tissues.
Ascorbic acid (vitamin C) is reversibly oxidised to dehydroascorbic acid; some is metabolised to ascorbate-2-sulphate, which is inactive, and oxalic acid which are excreted in the urine. Ascorbic acid (vitamin C) in excess of the body's needs is also rapidly eliminated unchanged in the urine.
5.3 Pre-clinical Safety Data
There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
