Psychosis: Goals of Pharmacotherapy

Psychosis: Goals of Pharmacotherapy

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...

Heart Failure Drugs: Diuretics

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Heart Failure I: Introduction

Heart Failure I: Introduction

Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Heart Failure Drugs: Inotropic Agents

Heart Failure Drugs: Inotropic Agents

Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...

Cardiomyopathy II: Dilated Cardiomyopathy

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Pathophysiology of Heart Failure

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Area of Science:

Geriatric Medicine
Psychopharmacology
Cardiology

Background:

Clozapine is an atypical antipsychotic used for treatment-resistant schizophrenia and other psychotic disorders.
Elderly patients often have comorbidities and altered pharmacokinetics, increasing susceptibility to adverse drug reactions.
Cardiac complications are a known, albeit rare, side effect of clozapine therapy.

Purpose of the Study:

To report a case of cardiac failure in an elderly patient treated with clozapine.
To emphasize the potential cardiotoxicity of clozapine in the geriatric population.
To highlight the importance of cautious prescribing and monitoring of clozapine in elderly individuals.

Main Methods:

Case report of a 73-year-old female patient with dementia and treatment-resistant psychotic symptoms.
Administration of clozapine for psychotic symptom management.
Observation and documentation of subsequent cardiac failure.

Main Results:

The patient developed cardiac failure following initiation of clozapine therapy.
The adverse event occurred in an elderly patient with a history of dementia.

Conclusions:

Clozapine treatment, even in elderly patients with dementia, carries a risk of serious cardiac adverse events.
Healthcare providers should exercise caution and consider close cardiac monitoring when prescribing clozapine to geriatric patients.
This case underscores the need for individualized risk-benefit assessments in elderly patients initiating clozapine.
