[1] IS GREEN TEA A POTENTIAL TRIGGER FOR AUTOIMMUNE HEPATITIS?.
EUGENIA GALLO,VALENTINA MAGGINI,MARGHERITA BERARDI,ET AL.
PHYTOMEDICINE 2013 Vol.20(),1186-9  $47451 [Full]

Part Used : ใบ
Activity : CYP3A4 INDUCTION
Solvent/Active Compound : -
Type of experiment : human
Type of animal : -
Type of study : Case report
N(Total) : 1
N(Treatment) : 1
Sex : Female
Age : 42 yrs
Route : Oral administration
Dose/Conc.(herb) : 1 g/ die of catechins
Duration : 10 days
Type of interaction : Pharmacokinetics
Interaction with drug : Irbesartan
Dose/Conc.(drug) : 150 mg/day
Result : Positive
Remark : The patient, carrying genetic variant of hepatic metabolism making her particularly susceptible to oxidative stress, developed an abnormal response to a mild toxic insult, afforded by a combination of agents (oral contraceptives + irbesartan + green tea) that normally would not be able to cause damage. Her particular hepatic metabolism might have further increased the drugs' concentration, favoring the haptenization of liver proteins, eventually leading to the development of an autoimmune hepatitis.

[2] EFFECTS OF CONTINUOUS INGESTION OF GREEN TEA OR GRAPE SEED EXTRACTS ON THE PHARMACOKINETICS OF MIDAZOLAM.
NISHIKAWA M,ARIYOSHI N,KOTANI A,ET AL.
DRUG METABOLISM AND PHARMACOKINETICS 2004 Vol.19(4),280-9  271495 [Abstract]

Part Used : ไม่ระบุ
Activity : CYP3A4 INDUCTION
Solvent/Active Compound : -
Type of experiment : in vivo
Type of animal : rat
Type of study : -
N(Total) : -
N(Treatment) : -
Sex : -
Age : -
Route : -
Dose/Conc.(herb) : -
Duration : 1 weeks
Type of interaction : Pharmacokinetics
Interaction with drug : Midazolam*/Versed/Dormicum
Dose/Conc.(drug) : -
Result : Positive
Remark : Although single treatments with green tea exts. or grape seed ext. had negligible effects, 1 wk of treatment with them resulted in a significant increase in the ke of i.v. administered midazolam (MDZ), indicating the induction of CYP3A in the liver.
