Objective. Anxiety disorders are frequently under-diagnosed conditions in primary care, although they can be managed
effectively by general practitioners.
Methods. This paper is a short and practical summary of the World Federation of Biological Psychiatry (WFSBP) guidelines for the pharmacological treatment of anxiety disorders, obsessive – compulsive disorder (OCD) and posttraumatic stress disorder (PTSD) for the treatment in primary care. The recommendations were developed by a task force of 30 international experts in the fi eld and are based on randomized controlled studies. Results. First-line pharmacological treatments for these disorders are selective serotonin reuptake inhibitors (for all disor-ders), serotonin-norepinephrine reuptake inhibitors (for some) and pregabalin (for generalized anxiety disorder only). A combination of medication and cognitive behavior/exposure therapy was shown to be a clinically desired treatment strategy. Conclusions. This short version of an evidence-based guideline may improve treatment of anxiety disorders, OCD, and PTSD in primary care.

Short description of anxiety disorders as defi ned by ICD-10  and DSM-IV-TR . Panic disorder (PD)
Panic disorder is characterized by recurrent panic attacks. Panic attacks are discrete periods of intense fear or discomfort, accompanied
by at least four somatic and psychic symptoms (palpitations, sweating, trembling, dyspnoea, choking sensations, chest pain, nausea, abdominal distress, dizziness, feeling of unreality, fear of dying, etc.). A panic attack reaches a peak within 10 min and lasts 30 – 45 min on average. Usually, the patient is afraid that he has a serious medical condition such as myocardial infarction.
About two-thirds of all patients with panic disorder suffer from agoraphobia, which is defi ned as fear in places or situations from which
escape might be diffi cult or in which help may not be available in the event of having an unexpected panic attack. These situations include being in a crowd or standing in a line, being outside the home alone, or traveling in a bus, train or automobile. These situations are avoided or endured with marked distress.
Generalized anxiety disorder (GAD)
The main features of generalized anxiety disorder are excessive anxiety and worry. The patients suffer from somatic anxiety symptoms
as well as from restlessness, irritability, diffi culty concentrating, muscle tension, sleep disturbances and being easily fatigued. Patient may express constant worry that the patient or a relative will shortly become ill or have an accident.
Specifi c phobia
Specifi c phobia is characterized by excessive or unreasonable fear of single objects or situations (e.g., fl ying, heights, animals, seeing
Social phobia (social anxiety disorder; SAD)
This disorder is characterized by marked, persistent, and unreasonable fear of being observed or evaluated negatively by others in social
performance or interaction situations and is associated with somatic and cognitive symptoms. The feared situations are avoided or else are endured with intense anxiety or distress. These situations include fear of speaking in public, speaking to unfamiliar people or being exposed to possible scrutiny by others.
Obsessive-compulsive disorder (OCD)
OCD is characterized by recurrent obsessions or compulsions, or both, that cause impairment in terms of distress, time, or interference
with functioning. Concerns involving contamination, harm, hoarding, and sexual, somatic and religious preoccupations are the most common obsessions. Compulsions include washing, checking, repeating, ordering, counting, hoarding and touching (rare).
Post-traumatic stress disorder (PTSD)
PTSD develops after a terrifying ordeal that involved physical harm or the threat of physical harm. The person who develops PTSD
may have been the one who was harmed, the harm may have happened to a loved one, or the person may have witnessed a harmful event that happened to loved ones or strangers. The condition is characterized by recurrent and intrusive distressing recollections of the event, nightmares, a sense of reliving the experience with illusions, hallucinations, or dissociative fl ashback episodes, intense psychological or physiological distress at exposure to cues that resemble the traumatic event, avoidance of stimuli associated with the trauma, inability to recall important aspects of the trauma, loss of interest, estrangement from others, sleep disturbances, irritability, diffi culty concentrating, hypervigilance, and exaggerated startle response.
