Pharmalogical TreatmentsPharmalogical Treatments“Trials”“Trials”

Tricyclic antidepressants ($15/month)– Imipramine, Noratriptyline, Desipramine & Amitriptyline

MAO Inhibitors*- ($15/month)– Nardil, Parnate & Marplan: 4-5 week build-up

Heterocyclic antidepressants ($50-120/month)– 4 to 8 weeks to produce effect– SSRI’s (Prozac, Zoloft, Celexa)– Dopamine specific reuptake inhibitors (Wellbutrin)

Lithium (for Bipolar D/O)

Response to Response to Pharmacological TreatmentPharmacological Treatment

Typical 3 part response– Sleep improves– Energy increases– Mood improves

Suicide potential greatest after energy increases, but before mood improves

Who Rx’s most antidepressants?– Problems?

Consider side effect profile

Page 19: Mood Disorders. Mental Problems Related to Mood l Mood episodes l Mood Disorders l Specifiers.

Predictors of Response to Predictors of Response to Antidepressant MedicationAntidepressant Medication

Positive– Gradual onset– Anorexia with weight loss– Middle, Late Insomnia– Psychomotor retardation

Negative– Multiple prior episodes– Delusions & more “complicated” problems

Outcome of Antidepressant Outcome of Antidepressant TreatmentTreatment

Average duration of MDD= 6 months 66% with MDD recover within 1 year and

80% recover within 2 years Among recovered patients, 33% will relapse

in 1 year; 75% will relapse in 5 years Double depression (MDD + Dysthymia)

doubles relapse rate Only 15% of hospitalized will not relapse
