This study aimed to determine the theory of constraints in inventory management as applied by drugstores in Binangonan, Rizal with respect to identifying the constraint, exploiting the constraint, subordinating the constraint, elevating the constraint, and repeating the process. The researchers used the descriptive method using the questionnaire checklist to 60 respondents who were the owners, store manager and head of inventory. The data collected were allied, tabulated, analyzed and interpreted using statistical treatments such as frequency percentage, rank distribution, weighted mean and one-way analysis of variance. Based on the analysis and interpretation made, the researcher summarize the following: Majority of the respondents were middle adulthood, female, married and College graduate. In terms of form of business organization, majority were operating their business under sole proprietorship with 1-2 workers. Most of them were in the service industry for less than 5 years, majority had an initial capital of P250,000 and below. Based on the data, drugstores first identified the bottleneck that limits product flow and then maximize its output. Other processes were adjusted to support the constraint, and capacity is increased when necessary. The system is continuously monitored to ensure ongoing improvement. There was no significant difference on the perception of the respondents in terms of sex, civil status, highest educational attainment, employment status, position held, form of business, years of operation, number of personnel, operating hours, source of capital, present capital, initial capital, and monthly income. While, a significant difference was noted with respect to age. The researchers recommended that drugstores in Binangonan, Rizal may consider maintaining an effective inventory management, may explore the integration of appropriate technologies, focus on addressing frequent stockouts of high-demand or fast-moving medications, expand capacity through additional storage facilities or by hiring more staff, and continuously assessing the identified constraints. Future researchers who will conduct similar study may consider using other variables for the attainment of a broader perception and knowledge on the inventory management of drugstores.
