Final answer:
Beta blocker overdose signs include bradycardia, hypotension, and respiratory distress, and may progress to seizures and coma in severe cases. Beta blockers are used to manage cardiovascular conditions by blocking ß-receptors, which dilates blood vessels and controls heart rate.
Step-by-step explanation:
Signs and Symptoms of Beta Blocker Overdose
The signs and symptoms of beta blocker overdose can vary in severity but characteristically include bradycardia (abnormally slow heart rate), hypotension (low blood pressure), and respiratory distress. Additional symptoms may consist of agitation, anxiety, sleep problems, and nausea and vomiting. In more severe cases, patients may exhibit signs of heart failure, shock, and loss of consciousness. Miosis (pinpoint pupils), muscle twitching, seizures, and coma can also manifest in cases of severe intoxication. Immediate medical attention is crucial for managing and treating a beta blocker overdose.
Common Effects of Beta Blockers
Beta blockers, such as metoprolol and propranolol, are primarily used to treat cardiovascular conditions by blocking ß-receptors associated with vasoconstriction and cardioacceleration. This action helps in dilating blood vessels and preventing an increase in heart rate, consequently improving cardiac function in patients with issues such as congestive heart failure or previous heart attacks.
