ππ§ Classification of Antipsychotic Drugs
π Important for Psychiatric Nursing, Mental Health Nursing, Pharmacology Exams
π° Definition:
Antipsychotic drugs (also known as neuroleptics or major tranquilizers) are medications used to treat psychotic disorders , such as schizophrenia, bipolar disorder (manic phase), delusional disorder, and psychotic depression . β
They reduce hallucinations, delusions, thought disturbances, agitation, and aggression .
π§ Classification of Antipsychotic Drugs
π© I. Based on Generation:
β
A. First Generation (Typical) Antipsychotics
π§ͺ Block dopamine D2 receptors π― Effective for positive symptoms (hallucinations, delusions)
Examples:
Chlorpromazine
Haloperidol
Fluphenazine
Trifluoperazine
Thioridazine
Side Effects:
Extrapyramidal symptoms (EPS)
Tardive dyskinesia
Hyperprolactinemia
β
B. Second Generation (Atypical) Antipsychotics
π§ͺ Block both dopamine (D2) and serotonin (5-HT2) receptors π― Effective for both positive and negative symptoms (withdrawal, flat affect)
Examples:
Risperidone
Olanzapine
Clozapine
Quetiapine
Aripiprazole
Ziprasidone
Side Effects:
Less EPS
Weight gain
Diabetes risk (especially with clozapine, olanzapine)
Agranulocytosis (Clozapine)
π¨ II. Based on Potency (Typical Antipsychotics):
β
A. High-Potency
Haloperidol
Fluphenazine
Trifluoperazine π High EPS risk, less sedation
β
B. Low-Potency
Chlorpromazine
Thioridazine π High sedation and hypotension, less EPS
π Mechanism of Action:
Typical : Dopamine (D2) receptor antagonists
Atypical : Dopamine (D2) + Serotonin (5-HT2A) receptor antagonists
π©Ί Indications:
Schizophrenia
Acute mania
Psychotic depression
Delusional disorders
Aggression and agitation in dementia
Touretteβs syndrome
β οΈ Common Side Effects:
Extrapyramidal symptoms (EPS) :
Parkinsonism
Dystonia
Akathisia
Tardive dyskinesia
Sedation, weight gain, hypotension
Neuroleptic Malignant Syndrome (NMS) : life-threatening emergency
Agranulocytosis (esp. Clozapine)
π©ββοΈ Nurseβs Responsibilities:
Monitor for EPS and other side effects
Educate patient on medication adherence
Regular CBC for Clozapine
Encourage fluid intake, physical activity
Watch for NMS: high fever, muscle rigidity, confusion
π Golden One-Liners for Quick Revision:
π¨ Typical antipsychotics = block dopamine, more EPS
π¨ Atypical antipsychotics = block dopamine + serotonin, treat +ve and βve symptoms
π¨ Clozapine causes agranulocytosis β monitor WBC
π¨ Haloperidol = high-potency typical antipsychotic
π¨ NMS = medical emergency caused by antipsychotics

ππ§ Anti-Parkinsonism Drugs
π Important for Mental Health Nursing, Pharmacology, Neurology & Staff Nurse Exams
π° Definition:
Anti-Parkinsonism drugs are medications used to treat symptoms of Parkinsonβs disease or Parkinsonism caused by antipsychotic drugs (drug-induced Parkinsonism or extrapyramidal symptoms – EPS).
β
These drugs work by restoring the balance between dopamine and acetylcholine in the brain.
π§ Classification of Anti-Parkinsonism Drugs:
π© 1. Dopaminergic Drugs (Increase dopamine activity)
π§ͺ Used for idiopathic Parkinsonβs disease
Examples:
Levodopa + Carbidopa (Sinemet)
Amantadine
Bromocriptine (Dopamine agonist)
Pramipexole , Ropinirole
Mechanism:
Levodopa converts to dopamine in the brain
Carbidopa prevents peripheral breakdown of levodopa
π¨ 2. Anticholinergic Drugs (Decrease acetylcholine)
π§ͺ Used in drug-induced Parkinsonism (from antipsychotics) β
Most commonly used in psychiatric settings
Examples:
Trihexyphenidyl (most common)
Benztropine
Biperiden
Mechanism:
Reduce acetylcholine activity to balance dopamine-acetylcholine imbalance
Control tremors, rigidity, drooling
π§ 3. MAO-B Inhibitors
π§ͺ Inhibit breakdown of dopamineExamples:
π₯ 4. COMT Inhibitors
π§ͺ Enhance levodopa effectExamples:
π― Indications:
Parkinsonβs disease (idiopathic)
Drug-induced Parkinsonism (EPS due to antipsychotics)
Parkinsonian symptoms: rigidity, bradykinesia, tremors
Akathisia, dystonia (with anticholinergics)
β οΈ Side Effects of Anti-Parkinsonism Drugs:
πΉ Dopaminergic drugs (e.g., Levodopa):
Nausea, vomiting
Postural hypotension
Dyskinesia (involuntary movements)
Hallucinations/confusion in elderly
Wearing-off phenomenon
πΉ Anticholinergics (e.g., Trihexyphenidyl):
Dry mouth
Blurred vision
Constipation
Urinary retention
Cognitive impairment in elderly
π©ββοΈ Nursing Responsibilities:
π© 1. Before Administration:
Assess for tremors, rigidity, gait problems
Monitor for signs of EPS if patient is on antipsychotics
Check vital signs (orthostatic hypotension)
π¨ 2. Monitoring After Administration:
Monitor for side effects (confusion, hallucination, dyskinesia)
Assess effectiveness β improvement in motor symptoms
Check for overdose signs (increased movements, restlessness)
π§ 3. Patient Education:
Take Levodopa with food to reduce nausea (but low protein diet preferred)
Do not stop suddenly β may worsen Parkinsonism
Avoid driving if dizzy or drowsy
For anticholinergics: increase fluids, fiber to avoid constipation
Use sugar-free candies for dry mouth
π₯ 4. In Psychiatric Settings:
Use Trihexyphenidyl or Benztropine to treat EPS from antipsychotic use
Teach patient to report muscle stiffness, tremor, or drooling
π Golden One-Liners for Revision:
π¨ Trihexyphenidyl is used to treat drug-induced Parkinsonism (EPS)
π¨ Levodopa is the most effective drug for Parkinsonβs disease
π¨ Anticholinergics are avoided in elderly with glaucoma or BPH
π¨ Side effects of anticholinergics = dry mouth, urinary retention, blurred vision
π¨ Abrupt withdrawal of Parkinsonβs drugs can lead to neuroleptic malignant-like syndrome
