Description: Objective: To analyze trends in antidepressant AD prescription rates among the elderly aged 65 years and older in Alberta during 1997 to 2004. Method: Numerical data on AD prescriptions were obtained from Alberta Blue Cross. Age-standardized prescription rates were calculated according to type of AD. Results: The prescription rate for all ADs combined increased by 59% for men and 55% for women. This change was due entirely to serotonin reuptake inhibitors SSRIs and other recently-introduced ADs, that by 2004 accounted for 72% of AD prescriptions for men and 69% for women. For each year and type of AD, the prescription rate for women was almost double that for men. Conclusions: In the elderly in Alberta, prescription rates for ADs increased markedly during 1997 to 2004, especially for SSRIs and other recently introduced ADs

Brief Communication Trends in Antidepressant Prescriptions Among the Elderly in Alberta During 1997 to 2004 Stephen C Newman, MD, MSc1; Don Schopflocher, PhD2 Objective: To analyze trends in antidepressant (AD) prescription rates among the elderly (aged 65 years and older) in Alberta during 1997 to 2004. Method: Numerical data on AD prescriptions were obtained from Alberta Blue Cross. Age-standardized prescription rates were calculated according to type of AD. Results: The prescription rate for all ADs combined increased by 59% for men and 55% for women.
This change was due entirely to serotonin reuptake inhibitors (SSRIs) and other recently-introduced ADs, that by 2004 accounted for 72% of AD prescriptions for men and 69% for women.
For each year and type of AD, the prescription rate for women was almost double that for men. Conclusions: In the elderly in Alberta, prescription rates for ADs increased markedly during 1997 to 2004, especially for SSRIs and other recently introduced ADs. Can J Psychiatry 2008;53(10):704–707 Clinical Implications · The rate of AD prescriptions in the elderly is rising, especially for SSRIs and other recently introduced ADs. · The rate of AD prescriptions in elderly women is almost double that for men. Limitations · The data available to us did not include information on dose of AD, adherence, or diagnosis. Key Words: antidepressant, elderly, trends 1 amdani et al used data from the Ontario Drug Benefits database from 1993 to 1997 to determine trends in the volume of AD prescriptions among the elderly (aged 65 years and older) in Ontario.
For that study, ADs were categorized as TCAs, heterocyclics, SSRIs, and MAOIs.
Among prescriptions filled in 1993, SSRIs and TCAs accounted for 14% and 75%, respectively, while in 1997 the corresponding estimates were 43% and 45%.
Mamdani et al2 extended this analysis from 1993 to 2002, and found that the trends for TCAs and SSRIs persisted.
Raymond et al3 analyzed data from a province-wide c...
