International journal of clinical pharmacology and therapeutics 2023 JunChemotherapy-induced nausea and vomiting (CINV) and chemotherapy-associated dyspepsia syndrome (CADS) are frequently appearing adverse effects of cisplatin (CDDP)-containing chemotherapy. Antiemetic guidelines suggest that the administration of antacids such as proton pump inhibitors (PPIs) or histamine type-2 receptor antagonists be considered for CADS, although their efficacy for treating these symptoms remains unknown. This study aimed to reveal whether antacids attenuate gastrointestinal symptoms in CDDP-containing chemotherapy. In total, 138 patients with lung cancer who received ≥ 75 mg/m2 CDDP-containing regimens were enrolled in this retrospective study. Patients were divided into an antacid group including patients administered PPIs or vonoprazan during all chemotherapy periods and controls without antacid administration. The primary endpoint was the comparison of anorexia incidence during the first cycle of chemotherapy. Secondary endpoints were CINV evaluation and risk factor analysis for the incidence of anorexia using logistic regression analysis. The incidence of anorexia during the first cycle was 54.4% in the control group and 60.3% in the antacid group, without significant differences (p = 0.60). The incidence of nausea was also similar between the groups (p = 1.00). Multivariate analysis suggested that antacid administration was not associated with anorexia. Baseline antacid administration does not affect gastrointestinal symptoms associated with CDDP-containing treatment in lung cancer.
