| Popis: | The pharmacology and pharmacokinetics of clonidine and the symptoms and treatment of acute clinidine overdosage are reviewed. Clonidine, a relatively safe and effective antihypertensive agent when used at therapeutic dosages, reduces blood pressure through a centrally mediated reduction in vasomotor tone. The primary symptoms of clonidine overdosage are central nervous system depression, bradycardia, hypotension, miosis, hypotonia, respiratory depression and possibly seizures. Gastric lavage followed by administration of activated charcoal is used to decrease absorption following acute oral ingestion. Intravenous fluid therapy and dopamine infusion are recommended for severe hypotension, and atropine sulfate is used to manage persistent bradycardia. Treatment of hypotension with alpha-adrenergic blocking agents (e.g., tolazoline) is not recommended unless patients fail to respond to dopamine infusion and administration of i.v. fluids. |
