Objective: To investigate patterns of opioid prescribing for pain treatment in patients with different age and gender. This cross sectional study conducted at outpatient pharmacy Hospital Tengku Ampuan Afzan Kuantan (HTAA).

Outcome measures included number of patients and prescriptions, age, gender and types of opioid. All analyses were performed using Stata 13 (Stata Corp LP, Texas, USA). Overall, 270 patients were prescribed with opioid analgesics from 2013 to 2014. Of these, 121 (44.8%) were women and 149 (55.2%) were men. The predominant age groups for women and men were 51-65 and 66-80 years old respectively. During the same study period, 481(44%) prescriptions for opioid analgesics were prescribed for women while 612(56%) for men. Oxycodone was the most frequently prescribed in both women and men (39.5% vs. 38.6%) primarily for younger patients (
