Iu. Zviarynski et Lb. Zavodnik, The effect of folic acid on the drug metabolizing liver function in man with viral hepatitis, EXP TOX PAT, 51(4-5), 1999, pp. 455-457
The investigations were carried out on 31 patients (16 men and 15 women, at
the age of 20-50) with viral hepatitis. The all patients were divided at t
wo groups. The first group (12 man) received usual treatment (diet, corsil)
, the second group (19 man) received in addition to the base treatment foli
c acid (5 mg per day, 10 days). It was found, that at patients with viral h
epatitis was decreased the activity of mono-oxygenase system of liver. So,
period of semielimination (T1/2) of antipyrine (AP) was greater in 1,4 time
, area under the pharmacokinetic curve - 1,5 time and clearance was below b
y 39 % than in volunteers (29 man). On day of treatment only by corsil, the
rate of elimination of AP and clearance were increased by 34 and 31 % (p <
0.05) respectively, T1/2 was decreased by 23 % (p < 0.05) and area under t
he pharmacokinetic curve - 17 %. On 10 day of treatment by corsil with foli
c acid (5 mg per day), the rate of elimination of AP and clearance was incr
eased by 43 % (p < 0.05), area, under the pharmacokinetic curve and T 1/2 w
ere decreased by 30 and 33 % (p < 0.05) respectively. The positive effect o
f folic acid in treatment of hepatitis at restoration period may be cause p
articipating its derivatives in de novo nucleotide synthesis.
