ABSTRACTIntroduction. Medication costs exceed the cost of health care. We evaluated the cost variation in medications purchased by our tertiary care-level facility according to therapeutic group and type during 2005 and 2006.
Methods. Using the Mexican Ministry of Health catalogue as a reference, each medication registered in the hospital pharmacy data base was assigned a code by type and therapeutic group. Both unit price as well as total quantities purchased were registered according to the aforementioned catalogue.
Results. The medication costs for 2005 and 2006 were $49 088 923.00 and $58 360 072.00 Mexican pesos, respectively, representing a 15.89% increase over a one-year period. The therapeutic groups representing the highest costs were medications for infectious diseases, electrolyte solutions, and anesthesia. When we considered costs by unit price, a negative variation was observed for drugs in the pulmonary medicine category (-270%) but a positive variation for drugs in the rheumatology group, 10.6%. In 2005, 627 different code numbers were purchased, while these decreased to 534 in 2006. When we analyzed purchases by type, 15 medications accounted for 59.03% of the expenditure in 2005 and 50.60% in 2006. Drugs derived with biotechnology represented the highest unit price.
Conclusions. The increase in the total expenditure of medications purchased by therapeutic group (15.89%) was influenced by the increase in unit price (10.61%), by volumes purchased (12.25%) and by inflation factor.
