Clinical Studies Investigating Silymarin in the Treatment or Prevention of Liver Disease

Reference CitationType of StudyType of DiseaseNo. of Patients: Enrolled; Treated; ControlaStrongest Benefit Reported
ALL = acute lymphoblastic leukemia; ALT = alanine aminotransferase; HCV = hepatitis C virus; LFT = liver function test; No. = number.
a Number of patients treated plus number of patients controlled may not equal number of patients enrolled; number of patients enrolled = number of patients initially recruited/considered by the researchers who conducted a study; number of patients treated = number of enrolled patients who were administered the treatment being studiedAND for whom results were reported; historical control subjects are not included in number of patients enrolled.
b Nine patients were excluded from the final analysis (seven patients missed appointments, and two patients were missing data requirements).
c Study investigated dose-response relationships. Patients wererandomlyassigned to receive 80 mg 2 times a day (n = 20), 120 mg 2 times a day (n = 20), or 120 mg 3 times a day (n = 20). The effective dose was 120 mg 2 times a day and 120 mg 3 times a day.
d Patients were randomly assigned to the misoprostol and silymarin groups. Twelve nonrandomized patients served as controls.
e Fifteen patients were lost to follow-up, 18 patients were deceased, and 42 patients withdrew from the study (adverse events, noncompliance, and voluntary withdrawal).
f Eleven patients did not complete the trial (voluntary withdrawal, disease progression, and one adverse event).
