Objective: This study investigates the impact of repeated oral exposure to two cough syrups containing codeine and dextromethorphan (DXM) on male Wistar rats.
Methods: We divided 35 rats into seven groups of five rats each. Group A was given 0.5 mL of distilled water, Groups B, C, and D were given 0.1, 0.2 and 0.4 mL/kg body weight (b. w) of cough syrup containing codeine (CSC), respectively, and Groups E, F, and G were administered 0.1, 0.2 and 0.4 mL/kg b. w of cough syrup containing DXM, respectively. The treatment was continued for 28 days. The rats were euthanised under mild diethyl ether anaesthesia. The kidney, liver, and blood of the rats were examined for further analyses.
Results: Significant (p < 0>
Conclusion: The findings of this study suggest that overdose of these cough syrups may predispose the consumer to hepatic and renal injuries.
