  • 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].

The motor manifestations of Parkinson’s disease (PD) are secondary to a dopamine deficiency in the striatum. However, the degenerative process in PD is not limited to the dopaminergic system and also affects serotonergic and noradrenergic neurons. Because they can increase monoamine levels throughout the brain, monoamine reuptake inhibitors (MAUIs) represent potential therapeutic agents in PD. However, they are seldom used in clinical practice other than as antidepressants and wake-promoting agents. This review article summarises all of the available literature on use of 50 MAUIs in PD. The compounds are divided according to their relative potency for each of the monoamine transporters.
