The aim of the present study was to investigate the effect of silymarin (Livergol) on liver enzymes in patients taking isotretinoin (Roaccutane). In this double‐blind clinical trial, 74 patients with acne and taking isotretinoin were randomly assigned into intervention (N = 37) and control (N = 37) groups. The intervention group received a 140 mg Livergol capsule per day for 30 days. The control group received a starch‐containing capsule as a placebo once a day for 30 days. Liver enzyme levels were measured before and after the intervention. The data were analyzed using chi‐square test, Independent t test, paired sample t test and analysis of covariance (ANCOVA). The results showed no statistically significant difference between the intervention and control groups at the beginning of study in levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) (p > .05). At the end of the study, a statistically significant difference was observed between the two groups in levels of AST and ALT (p < .05). Livergol prevented liver enzymes from increasing, so it can be used as an effective, low‐cost, and low‐complication treatment for the problem of increased levels of liver enzymes following the use of isotretinoin.
Background and Objective: Nausea, vomiting, and anorexia are the most common side effects reported in cancer patients undergoing chemotherapy. The present study aimed to determine the effect of peppermint extract on the severity of nausea, vomiting, and anorexia in patients with breast cancer undergoing chemotherapy. Methods and Materials: In this randomized controlled trial, we selected 84 patients with breast cancer undergoing chemotherapy. They were then assigned to 2 groups of experimental and control (n = 42, each) using block randomization. Patients in the experimental group received 40 drops of peppermint extract mixed in 20 cc of tap water every 8 hours, while patients in the control group received 40 drops of distilled water mixed in 20 cc of tap water every 8 hours. The severity of nausea, vomiting, and anorexia was measured and recorded before the intervention, and immediately, 24 and 48 hours after the chemotherapy using the Visual Analogue Scale. Statistical analysis of the data was conducted using SPSS software version 21. Results: The results of the present study revealed that there was a significant difference between the 2 groups at 24 and 48 hours after the chemotherapy ( P < .05), so that the mean score of the severity of nausea, vomiting, and anorexia in the experimental group was lower than in the control group ( P < .05). Conclusion: The use of peppermint as a method in complementary medicine may improve nausea, vomiting, and anorexia in patients with breast cancer undergoing chemotherapy. Further studies with greater sample size and longer follow-up period are needed to confirm the current findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
