Antipsychotics And Schizophrenia Treatment Discussion
Psychopharmacology entails all the medication used in treating mental health illnesses. Medications can help play a significant role in most types of mental illnesses. Mental illness disorders require using a single medication, while others involve using combinations to achieve therapy. Effective medications for most mental illnesses involve a combination of drugs and psychotherapy. Other psychiatric may require multiple combinations to achieve an effective outcome. Finding the underlying cause of a mental disorder is the most significant in determining the kind and type of medication to alleviate the bizarre behaviors (Ceraso et al., 2020). Underlying causes resulting in mental disorders include; pain, chronic psychiatric illness such as schizoaffective disorder, environmental triggers (excessive heat, noise, and overcrowding), substance intoxication, medical illness such as Alzheimer’s disease, and acute psychotic illness. Antipsychotics And Schizophrenia Treatment Discussion
Psychotic disorders are abnormalities in perception, beliefs, and thought processes. Psychotic disorders are prevalent in about 1% of the general population. The first onset of psychotic disorders affects individuals between the ages of fifteen and forty-five (Freudenreich et al., 2016). Men are termed to exhibit early symptoms than women. The most common type of psychotic disorders includes schizophrenia, schizoaffective disorder, and brief psychotic disorder substance-induced disorder.
Antipsychotic medication
Antipsychotic medication is classified into the first and second generations. The first antipsychotic generation is known as a dopamine receptor antagonist, also known as typical antipsychotics. The second-generation antipsychotic medication is knowns as a serotonin – dopamine receptors antagonist and is also knowns as a typical antipsychotic medication.

Indications of antipsychotic medications
Schizophrenia ad schizoaffective disorders. First-generation antipsychotics are better for alleviating symptoms of schizophrenia, such as hallucination, catatonia, and delusions; second-generation antipsychotics counteract negative symptoms of schizophrenia, such as withdrawal symptoms.
Major depressive symptom with psychotic features. A combination of antipsychotics worth antidepressants serves as the best treatment modalities for clients with major depressive disorders expressing themselves with psychotic symptoms. Olanzapine and fluoxetine, according to the FDA, serve as vest therapy for patients with major depressive disorders associated with psychotic symptoms.
The first-generation antipsychotic medications are indicated for psychiatric patients with delusions and paranoia associated with personality disorders. Antipsychotics And Schizophrenia Treatment Discussion
Typical antipsychotic drugs | ||||
Generic name | Trade name | The first dose (mg/day) | Maximum daily dose (mg/day) | Consideration |
haloperidol | Haldol | 25- 100 | Oral ranges from 100 to 2000 | Intramuscular dosage is specifically 25 – 50 mg and never injected subcutaneously. |
Fluphenazine | Prolixin | 2.5 -10 | Oral dose not exceeding 40
Intramuscular- 10 |
The concentrate should be diluted immediately and administered to ensure palatability and stability of the drug |

Pharmacokinetics of antipsychotic medications
Absorption of antipsychotic medication solely depends on the characteristics of the drugs. Drugs taken orally differ between sexes. Gastric acidity is lower in women than men; thus, gastric emptying is slower. The solubility of antipsychotic drugs taken orally is affected by the composition of the bile acid. Metabolism of antipsychotics is achieved metabolized by the cytochrome P450 (Huang et al., 2018). Fluphenazine, perphenazine, haloperidol, risperidone, and thioridazine are actively metabolized by CYP2D6.
Antipsychotic medications are eliminated from the blood via hepatic, renal, and breast milk. Hepatic blood among women is lower than in men. Psychotic medications are determined by the individual body weight and the extent to of the drug binding to blood proteins.
Half-life
Drug half lie refers to the time taken for the amount of the drug’s active substance in a person’s body to reduce by half.
Importance of half-life
The half-life of antipsychotic medications
Risperidone – extensive metabolization takes three hours
Lurasidone- eighteen hours
Haloperidol- twenty-one to twenty-four hours
Fluphenazine- fluphenazine hydrochloride takes 33 hours within the body system.
Clozapine- clozapine takes eight to twelve hours
Loxapine- three to four hours
Pimozide- pimozide takes the longest half-life, between twenty-nine and eleven hours.
Aripiprazole- take seventy-nine hours.
Atypical antipsychotics are a newer class of antipsychotics that are less likely to cause side effects than typical antipsychotics. Atypical antipsychotics work by blocking serotonin and dopamine receptors in the brain. Serotonin is a neurotransmitter that is involved in the regulation of mood and emotions. Dopamine is a neurotransmitter that is involved in the development of psychosis (Alanen, 2018). Atypical antipsychotics help to reduce the symptoms of psychosis, such as delusions and hallucinations
Side effects
The main side effects of the medication used to treat schizophrenia are weight gain, drowsiness, and dry mouth. Other side effects may include constipation, blurred vision, and low blood pressure. Some more severe side effects of the medication used to treat schizophrenia are seizures, difficulty breathing, and an irregular heartbeat (Alanen, 2018).
Contraindications
Some of the contraindications of the medication used to treat schizophrenia include hypersensitivity to the medication, a history of seizures, and narrow-angle glaucoma. Other potential contraindications include pregnancy, breastfeeding, and children under 12 (Alanen, 2018). Antipsychotics And Schizophrenia Treatment Discussion
Overdose considerations
When treating schizophrenia with medication, it is essential to be aware of the potential for overdose. Symptoms of an overdose may include drowsiness, confusion, slurred speech, and loss of coordination. If these symptoms occur, it is essential to seek medical help immediately (Alanen, 2018).
Diagnostics
Diagnostics and lab monitoring allow for proper and timely intervention if any changes or worsening in symptoms are observed. Additionally, regular lab monitoring can help identify any potential side effects of medication or other treatments (Alanen, 2018).
Comorbidities considerations
The most common comorbidity among people with schizophrenia is depression. Other common comorbidities include anxiety, substance abuse, and eating disorders. Treatment for comorbidity must consider each disorder’s different symptoms and needs (Alanen, 2018).
Legal and ethical considerations
The legal considerations in treating schizophrenia mostly center on the patient’s right to refuse treatment. In many cases, people with schizophrenia cannot make decisions about their treatment, so involuntary treatment is often necessary. The ethical considerations are mostly centered on the potential for harm caused by the treatments for schizophrenia. There is a risk of severe side effects from many medications used to treat schizophrenia, so the decision to use them should be made carefully (Alanen, 2018).
Patient education considerations
Patient education considerations in treating schizophrenia include informing the patient about the nature of the disorder, the potential for relapse, and the importance of compliance with medication and other treatment regimens. It is also essential to educate the patient’s family and caregivers about the disorder and the need for support (Alanen, 2018). Other considerations include helping the patient to develop coping and problem-solving skills and to identify and avoid stressors that can trigger symptoms.

Psychosis and schizophrenia greatly impact the brain’s normal processes, which interfere with the ability to think clearly. When symptoms of these disorders are uncontrolled, patients may struggle to function in daily life. However, patients often thrive when properly diagnosed and treated under the close supervision of a psychiatric mental health practitioner. For this Assignment, you will develop a study guide for an assigned psychotropic agent for treating patients with Schizophrenia Spectrum and Other Psychotic Disorders. You will share your study guide with your colleagues. In sum, these study guides will be a powerful tool in preparing for your course and PMHNP certification exam.
