Aristada™ (Aripiprazole Lauroxil)
Aristada™ (aripiprazole lauroxil) – New Drug Approval • On October 5, 2015, Alkermes’ announced the FDA approval of Aristada (aripiprazole lauroxil) extended-release injection, an atypical antipsychotic, for the treatment of schizophrenia. • Schizophrenia is a chronic, severe and disabling brain disorder affecting an estimated 2.4 million Americans. Typically, symptoms include hearing voices, believing other people are reading their minds or controlling their thoughts, and being suspicious or withdrawn. • Aristada’s approval was based on data from a double-blind, placebo-controlled 12-week trial involving 622 patients with schizophrenia. In addition, the efficacy of Aristada was established, in part, on the basis of efficacy data from trials with oral aripiprazole. — Aristada significantly improved symptoms of schizophrenia compared to placebo at day 85. • Similar to other atypical antipsychotics, Aristada carries a boxed warning for increased mortality in elderly patients with dementia-related psychosis. • Other warnings and precautions for Aristada include cerebrovascular adverse reactions, including stroke; neuroleptic malignant syndrome; tardive dyskinesia; metabolic changes; orthostatic hypotension; leukopenia, neutropenia, and agranulocytosis; seizures; potential for cognitive and motor impairment; body temperature regulation; and dysphagia. • The most common adverse reaction (≥ 5% and at least twice that for placebo) with Aristada use was akathisia. • Aristada is administered by intramuscular injection in the deltoid (441 mg dose only) or gluteal (441 mg, 662 mg, or 882 mg) muscle by a healthcare professional. — Aristada can be initiated at a monthly dose (441 mg, 662 mg or 882 mg) or every 6 week dose (882 mg). — For patients naïve to aripiprazole, tolerability should be established with oral aripiprazole prior to initiating treatment with Aristada. -
Acute Extrapyramidal Symptoms Following Abrupt Discontinuation of Propranolol
Medical Journal of the Volume 14 Islamic Republic of Iran Number 3 Fall 1379 November 2000 ACUTE EXTRAPYRAMIDAL SYMPTOMS FOLLOWING ABRUPT DISCONTINUATION OF PROPRANOLOL A. ALAVIAN GHAVANINI From the Center Jor Research Consultation, School oj Medicine, Shiraz University ojMedical Sciences, Shiraz, I.R. Iran. ABSTRACT A case of acute extrapyramidal manifestations consisting of dystonia and akathisia following abrupt discontinuation of propranolol is reported. She re sponded well to oral propranolol and intramuscular diazepam. Extrapyramidal symptoms have commonly been associated with acute or chronic administration of neuroleptic drugs. There have been reports of a substantial number of cases with similar clinical characteristics associated with tricyclic antidepressants, monoamine oxidase inhibitors, and selective serotonin reuptake inhibitors. Al though it is known that beta-adrenoceptor antagonists are effective in the treat ment of extrapyramidal symptoms, especially akathisia, there has been no previ ous report of such symptoms induced by abrupt withdrawal of these drugs. Al though she had been on low dose amitriptyline and had discontinued this medica tion long before, prolonged use of amitriptyline may have had a predisposing role in the development of these symptoms.

Among the various side effects of anti-psychotics extra pyramidal symptoms constitute one of the important side effects interfering with the compliance of the patients towards medication. Objective: Evaluation of extrapyramidal side effects by AIMS in patients who are on antipsychotics. Results: The extrapyramidal symptoms were more commonly seen in males (62.85%), the age of incidence of maximum in the age group of 34.28, Maximum was seen among the patients on the Risperidone (45.7%), Involvement of the extremities was common (42.85%) and 64.28% of individuals had moderate severity and 54.28% of individuals were aware of the extrapyramidal symptoms which provided mild distress. Conclusion: Extrapyramidal symptoms are one of the commonest side effect of the antipsychotics interfering with compliance of the patients towards adherence to medications, thereby decreasing the efficacy. Keywords: Extrapyramidal symptoms; Compliance; Antipsychotics; positive symptom of the psychosis but have some serious limitations AIMS. such as lack of efficacy against negative symptoms and adverse effects like extrapyramidal symptoms [7]. -

Another View of the History of Antipsychotic Drug Discovery and Development
Molecular Psychiatry (2012) 17, 1168–1173 & 2012 Macmillan Publishers Limited All rights reserved 1359-4184/12 www.nature.com/mp PERSPECTIVE Another view of the history of antipsychotic drug discovery and development WT Carpenter Jr1 and JM Davis2 Chlorpromazine initiated effective pharmacotherapy for schizophrenia 60 years ago. This discovery initiated or stimulated key developments in the field of psychiatry. Nonetheless, advances in pharmacotherapy of schizophrenia have been modest. Psychosis remains the primary aspect of psychopathology addressed, and core pathologies such as cognition and negative symptom remain unmet therapeutic challenges. New clinical and basic neuroscience paradigms may guide the near future and provide a more heuristic construct for novel and innovative discovery.
