Summary
ADHD medication prescriptions in Turkey significantly increased between 2009 and 2013, with OROS methylphenidate dominating usage. This rise suggests potential over- and underdiagnosis challenges.
Area of Science:
- Pharmacology
- Psychiatry
- Public Health
Background:
- Attention-Deficit/Hyperactivity Disorder (ADHD) medication use is increasing globally.
- Understanding prescription trends is crucial for public health planning and resource allocation.
Purpose of the Study:
- To analyze changes in ADHD medication prescriptions in Turkey from 2009 to 2013.
- To identify trends in the utilization of specific ADHD medications.
Main Methods:
- Utilized IMS Health database for ADHD medication consumption data (immediate release methylphenidate, OROS MPH, atomoxetine).
- Calculated Defined Daily Doses (DDD) per WHO standards.
- Conducted time-series analysis to identify trends and seasonality.
Main Results:
- Overall ADHD medication use increased 2.18-fold between 2009 and 2012.
- OROS MPH accounted for approximately 75% of total ADHD medication utilization.
- A significant seasonal pattern was observed in the prescription of all studied ADHD medications.
Conclusions:
- ADHD medication consumption in Turkey has significantly risen, mirroring global trends.
- The observed increase may indicate concurrent issues of both overdiagnosis and underdiagnosis.
- Further research is needed to understand the drivers of these prescription patterns.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...

Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
