Summary
Adding amisulpride to risperidone significantly improved mental status in schizophrenia patients over three months. This combination therapy offers a potential treatment option for individuals with partial or non-response to risperidone monotherapy.
Area of Science:
- Psychiatry
- Pharmacology
- Clinical Research
Background:
- Antipsychotic combination therapy is a recognized clinical strategy.
- Risperidone monotherapy may not be effective for all schizophrenia patients.
Purpose of the Study:
- To assess the efficacy and safety of adding amisulpride to risperidone treatment.
- To evaluate treatment outcomes in patients with partial response to risperidone.
Main Methods:
- A 3-month open-label observational study.
- Inclusion criteria: BPRS score ≥ 25 after risperidone monotherapy.
- Outcome measures: BPRS, CGI-S, and UKU Side Effect Rating Scale.
Main Results:
- Significant improvement in mental status observed over 3 months (BPRS, CGI, UKU).
- Response rates: 45% for oral risperidone group and 28% for parenteral risperidone group.
- Coadjuvant amisulpride demonstrated statistically significant benefits.
Conclusions:
- Amisulpride addition may enhance schizophrenia symptom control in partial risperidone responders.
- Further investigation into alternative therapies for poor responders is warranted.

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

01:26Psychosis: Goals of Pharmacotherapy
694
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.

The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...
