Anxiety Disorders Management

Introduction to Anxiety Disorders

Anxiety disorders can be treated with standard drugs including escitalopram, paroxetine, sertraline, and venlafaxine, according to guidelines from the American College of Neuropsychopharmacology 1
Escitalopram is considered a preferred agent for depression and anxiety due to its favorable side effect profile, as recommended by the American Academy of Family Physicians and approved by the FDA 1, 2

Escitalopram may prolong QT interval at higher doses, though less than some other antidepressants, according to the European Society of Cardiology 3
The starting dose of escitalopram is 10 mg once daily for most adults, with a maximum dose of 20 mg once daily, as recommended by the American Academy of Family Physicians and approved by the FDA 1, 2
Elderly patients and those with hepatic impairment have a maximum recommended dose of 10 mg/day of escitalopram, while no dosage adjustment is necessary for mild to moderate renal impairment 1, 2
Buspirone (BuSpar) can be a useful alternative for patients with mild to moderate anxiety, with an initial dosage of 5mg twice daily and a maximum dosage of 20mg three times daily 4
Paroxetine has an increased risk of suicidal thinking or behavior compared to other SSRIs and should be used with caution, according to the American Academy of Child and Adolescent Psychiatry 5
Citalopram/escitalopram may have the least effect on CYP450 isoenzymes compared with other SSRIs, reducing drug interactions, as suggested by the American Academy of Child and Adolescent Psychiatry 5

For patients with cardiac risk factors, the European Society of Cardiology recommends considering ECG monitoring due to dose-dependent QT prolongation risk 3
Common adverse effects to monitor include diarrhea, dizziness, dry mouth, fatigue, headache, sexual dysfunction, sweating, tremor, and weight gain, with nausea and vomiting being the most common reasons for discontinuation 2
More serious adverse effects to watch for include serotonin syndrome, QT prolongation, and increased risk of suicidal thoughts and behaviors, especially in young adults 2
Caution is recommended when combining two or more serotonergic drugs due to the risk of serotonin syndrome, as advised by the American Academy of Child and Adolescent Psychiatry 5
Gradual dose reduction is recommended when discontinuing escitalopram, rather than abrupt cessation, to avoid withdrawal symptoms and monitor for discontinuation symptoms like dizziness, sensory disturbances, anxiety, and sleep disturbances 2

Cognitive behavioral therapy (CBT) should be structured with approximately 14 sessions over 4 months, as recommended by the American College of Neuropsychopharmacology 1
Individual CBT sessions (60-90 minutes) are preferred over group therapy due to superior clinical effectiveness, as suggested by the American College of Neuropsychopharmacology 1
Combination treatment, such as Cognitive Behavioral Therapy (CBT) and a Selective Serotonin Reuptake Inhibitor (SSRI), may be more effective than medication alone for patients with anxiety disorders, as suggested by the American Academy of Child and Adolescent Psychiatry 5

Initial response to sertraline can be expected within 2-4 weeks, with maximal response achieved within 8-12 weeks, and it is essential to continue treatment for at least 6-12 months after remission to prevent relapse 5
A dose of 20 mg/day of escitalopram showed statistically significant improvement compared to placebo in post-hoc analyses for social anxiety disorder, according to a Japanese study 1
When switching from escitalopram to sertraline, a recommended titration schedule is:
