Background Ulcer remains a health challenge worldwide with antibiotics and proton pump inhibitors as major management therapy. The study investigated the acute, sub-chronic toxicity and gastrointestinal protective activity of a polyherbal formulation (Mystomate4®) used locally in Nigeria. Methods Oral LD50 and the sub-chronic toxicity test were determined in mice and rats. Mice were grouped into 8 groups of 8 mice each. They were dosed a graded concentration of the formulation (1.28, 2.56; 5.12; 10.24; 20.48; 40.96; 81.92; 163.84 g/kg body weight). The graded dose used was arrived at after an initial pilot study. Thereafter doses were chosen around the dose obtained from the pilot study. Animal were dosed orally and observed for sign of toxicity and number of death recorded after 24 h. The sub-chronic toxicity study was carried out for 3 months in rats at a dose of 2.5 and 5.0 g/kg body weight arrived at by titrating down the LD50 value after which some vital tissues were harvested and assessed for toxicity using relevant biomarkers. Anti-ulcer activity was evaluated in rats using ethanol, indomethacin and pylorus ligation induced ulcer models. Data were analysed with Graph Pad Prism version 5.0 using appropriate statistical method and significant level placed at p ≤ 0.05. Results The acute toxicity study showed an LD50 result of 22,837.21 g/kg. The sub-chronic toxicity study resulted in a significant reduction in body weight due to significant decrease (p ≤ 0.05) in feed consumption. Biochemical analyses of the blood samples showed a significant increase (p ≤ 0.05) in creatinine and albumin level in the 2.5 mg/kg female group. ALT was significantly increased in all the treated rats except in 2 mg/kg female rats. Alkaline phosphatase significantly increased in high dosed male (HM) group while blood urea:creatinine ratio was significantly lowered in all the treated groups. There was a significant increase in serum TGL in all rats while LDL was significantly increased and decreased in HM and high dosed female (HF) respectively. Conclusion Mystomate4® showed significant protection against ethanol and indomethacin-induced ulcer models but did not modify the gastric parameters in pylorus ligation-induced ulcer model. The polyherbal formulation is nontoxic with promising potentials for treating experimental peptic ulcer. |
