A case of Bisoprolol induced delirium in an elderly patient

Delirium or ‘acute confusional state’ is a common clinical syndrome characterised by disturbed consciousness and cognitive function or perception.  Introduction Case Report Discussion Conclusion References Introduction Beta-blockers block the beta-adrenoceptors in the heart, peripheral vasculature, bronchi, pancreas and liver. Bisoprolol is a relatively cardio-selective beta blocker used mainly to control hypertension, angina, tachycardia-related arrhythmia and often as an adjunct in heart failure. Its common side effects include gastrointestinal disturbance, bradycardia, hypotension, conduction disorders, peripheral vasoconstriction, dyspnoea, headache, fatigue, dizziness and sexual dysfunction. Here we present the case of an increased dose of bisoprolol causing acute confusion in a 94-year-old woman.
