Study Notes
Drug Classification
- Clozaril is classified as an atypical antipsychotic.
Dose Range
- Initial oral dose: 12.5 mg, administered 1-2 times daily.
- Target dose: between 150-500 mg per day.
- Maximum allowable dose: 900 mg per day.
Pharmacological Action
- Primarily binds to dopamine receptors located in the central nervous system (CNS).
Therapeutic Uses
- Effective for treating schizophrenia that is unresponsive to or intolerant of other antipsychotic therapies.
- Used to reduce suicidal behaviors in patients with schizophrenia.
Side Effects/Adverse Effects
- Potentially severe reactions include neuroleptic malignant syndrome and seizures.
- Risk of cardiac arrest, deep vein thrombosis (DVT), ventricular arrhythmias, and pulmonary embolism.
- Possible blood disorders such as agranulocytosis and leukopenia.
Medication/Food Interactions
- May enhance anticholinergic effects when used with other medications.
- Oral contraceptives and caffeine can amplify clozapine's effects.
- Increased CNS depression when combined with alcohol, antidepressants, antihistamines, opioids, and sedative-hypnotics.
- Co-administration with Lithium can lead to heightened adverse CNS reactions, including seizures.
- St. John's Wort should be avoided.
Nursing Interventions/Client Education
- Monitor for extrapyramidal symptoms and inform patients about these risks.
- Smoking can lower clozapine levels, which may affect efficacy.
- Advise against alcohol and CNS depressants.
- Patients should report symptoms like palpitations, tachypnea, chest pain, sore throat, or flu-like symptoms to their physician.
- Pregnant or breastfeeding patients must notify their healthcare provider.
Nursing Administration Concerns
- Routine monitoring of white blood cells (WBCs) and absolute neutrophil count (ANC) is essential.
- Assessing fasting blood glucose levels is important due to potential metabolic side effects.
- Be aware that clozapine can lower seizure thresholds; assess respiration status regularly.
- Conduct baseline WBC counts, followed by weekly monitoring during treatment and for four weeks post-therapy.
- Agranulocytosis may occur 18-24 weeks after starting treatment.
Evaluation of Medication Effectiveness
- Effectiveness indicated by a decrease in positive schizophrenia symptoms, such as delusions and hallucinations.
- Reduction in negative symptoms, including social withdrawal and blunted affect, is also a marker of effectiveness.
