The traditional manual approach to medicine dispensing and inventory management in
pharmacies is prone to human error and inefficiency, particularly in critical tasks such as
verifying expiry dates and recording purchase histories. This prototype addresses these
critical issues by proposing the design, development, and evaluation of an Automated
Medicine Dispensing and Inventory System. The core component is a web server that
manages the information on the medicine inside the machine, notably the expiration dates.
The system automatically deducts the inventory when the sensor detects the medicine in
the catcher upon dispensing. It consists of four (4) vending machine motors in each row and
a NEMA23 stepper motor for the movement of the catcher where the medicine is
dispensed. Additionally, a drawer is installed below for storage of loose medication.
Functionality testing results showed that the component of the prototype is working
properly. Mainly the RFID and Ultrasonic Sensors. The prototype takes a minimum of 8.78
seconds and a maximum of 46.81 seconds to dispense one (1) medicine. When dispensing
two (2) medicines, the minimum is 49.45 seconds, and the maximum is 11.17 seconds. In
terms of system accuracy testing, the system automatically deducts the inventory when the
medicine dispensing is successful. The medicine dispensing released the correct medicine.
The prototype was evaluated by thirty (30) respondents using the TUP evaluation form and
got an overall rating of 4.35, equivalent to Very Good. This proves the prototype is more
efficient than the pharmacists' manual process.
