El largo y sinuoso camino de la farmacia clinica en Chile / The long and winding road of the clinical pharmacy in Chile

Clinical pharmacy is a health discipline in which pharmacists provide patient care that optimizes rational medication use and promotes health, wellness and disease prevention. The beginnings of clinical pharmacy in Chile were inspired by the origin in the School of Pharmacy of the University of California, San Francisco (UCSF), in the mid-1960s. However, the historical development in our country, both in teaching and in the professional field, was accompanied by difficulties and success, which became a long and winding road. This article shares the events that gave rise to its beginnings in Chile, first through teaching, then in pharmacovigilance and clinical pharmacokinetics, to later describe its professional expansion and recognition as a specialty of pharmacy. This article briefly recounts the history of the Chilean clinical pharmacy to this day. Some names of people or institutions were not mentioned. Therefore the authors apologize in advance to pharmacists and organizations whose contribution cannot be recognized in this way. However, we know that this specialty has not been forged only by the names that appear, but by all those who love and respect the work of the clinical pharmacy.

Consumo de antidepresivos en Chile entre 1992 y 2004 / Consumption of antidepressants in Chile from 1992 to 2004

Background: Data from the Ministry of Health show that in Chile in 2004, 17 percent of the population had some form of depression and mood disorders are the tenth cause of disability-adjusted Ufe years (DALY) loss. Aim: To determine consumption of antidepressants (ADs) in Chile from 1992 to 2004. Material and methods: National sales data were obtained from the company IMS Health Chile and converted into defined daily doses (DDDs) per 1,000 inhabitants per day Available ADs were classified in four pharmacological groups (i.e., serotonin-norepinephrine reuptake inhibitors, SNRIs; selective-serotonin reuptake inhibitors, SSRIs; tricyclic antidepressants, TCAs; and others). Total economic burden of ADs utilization and cost per DDDs were also calculated. Trends over time were analyzed using Pearson-R2. Results: Total ADs consumption in Chile measured by DDDs per 1,000 inhabitants per day (DHD) increased linearly (y =0.901x+1.9129; R2 =0.9296; p <0.001) from 2.5 in 1992 to 11.7 in 2004 (total growth of 470.2 percent). SSRIs were the drug class with higher consumption, and fluoxetine the most commonly consumed antidepressant. SSRIs were the drugs that dominated the market representing 79 percent of the total drug consumption throughout the years. Total economic burden of ADs in Chile (total cost of DDDs consumed) increased from US$65.4 million in 2001 to US$74.6 million in 2004 (14 percent increase). Average cost per DDD of all AD increased linearly, however not significantly from US$ 0.94 in 2001 to US$ 1.04 in 2004 (y =0.0362x+0.8784; R2 =0.7382; p =0,262). Conclusions: DDDs per 1,000 inhabitants per day increased linearly over 470 percent from 1992-2004. SSRIs were the most commonly consumed drugs in Chile. Future research should evaluate the cost-effectiveness of antidepressants in Chile, comparing the results with drug utilization, and determining if unnecessary expenditures have been paid out.
