In this study, an inventory model is developed for pharmaceutical products that experience deterioration due to prolonged storage time, with a demand rate modeled as a fourth-degree polynomial function. The model considers shortages that are allowed with complete backlogging, and it assumes a constant deterioration rate. In the optimal solution, the inventory depletion t_1^* is obtained as 0.058823, and the cycle length T_1^* is 0.920327, with a minimum average total cost (TC) ̅ of $393.96 per cycle, calculated using WolframAlpha software. Sensitivity analysis on parameter changes shows that (TC) ̅ increases for most parameters. An increase in the constant deterioration rate θ results in stable values for t_1^* and T_1^* An increase in the demand function parameter a leads to a decrease in t_1^* and T_1^* while (TC) ̅ increases. An increase in the demand function parameter b results in fluctuating t_1^* values and a decrease in T_1^(* )while (TC) ̅ increases. An increase in the cost per deteriorated item D_c leads to increases in both t_1^* and T_1^* along with a significant rise in (TC) ̅ . An increase in the holding cost h results in a decrease in t_1^* while T_1^* remains stable, but (TC) ̅ fluctuates. Meanwhile, an increase in the shortage cost s leads to increases in both t_1^* and T_1^(* )as well as in (TC) ̅.
