Perphenazine And Amitriptyline Hydrochloride

INDICATIONS AND USAGE Perphenazine and amitriptyline hydrochloride tablets are recommended for treatment of (1) patients with moderate to severe anxiety and/or agitation and depressed mood, (2) patients with depression in whom anxiety and/or agitation are severe, and (3) patients with depression and anxiety in association with chronic physical disease. In many of these patients, anxiety masks the depressive state so that, although therapy with a tranquilizer appears to be indicated, the administration of a tranquilizer alone will not be adequate. Schizophrenic patients who have associated depressive symptoms should be considered for therapy with perphenazine and amitriptyline hydrochloride tablets.

ADVERSE REACTIONS To date, clinical evaluation of perphenazine has not revealed any adverse reactions peculiar to the combination. The adverse reactions that occurred were limited to those that have been reported previously for perphenazine and amitriptyline. Treatment with perphenazine and amitriptyline hydrochloride is commonly associated with sedation, hypertension, neurological impairments and dry mouth. Perphenazine The common acute neurological effects of neuroleptic drugs, including perphenazine, consist of dystonia, akathisia or motor restlessness, and pseudoparkinsonism. More chronic use of neuroleptics may be associated with the development of tardive dyskinesia. The salient features of this syndrome are described in the WARNINGS section and below.

Pregnancy Nonteratogenic Effects Neonates exposed to antipsychotic drugs, during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. There have been reports of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder in these neonates. These complications have varied in severity; while in some cases symptoms have been self-limited, in other cases neonates have required intensive care unit support and prolonged hospitalization.

WARNING Increased Mortality in Elderly Patients with Dementia-Related Psychosis Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. WARNINGS Increased Mortality in Elderly Patients with Dementia-Related Psychosis Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Perphenazine and amitriptyline hydrochloride is not approved for the treatment of patients with dementia-related psychosis (see BOXED WARNING ). Clinical Worsening and Suicide Risk Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. CONTRAINDICATIONS Perphenazine and amitriptyline hydrochloride tablets are contraindicated in depression of the central nervous system from drugs (barbiturates, alcohol, narcotics, analgesics, antihistamines); in the presence of evidence of bone marrow depression; and in patients known to be hypersensitive to phenothiazines or amitriptyline.
