Psychotropics (“moving closer to a normal state”) refers to medications used to manage mental health disorders by adjusting brain chemistry. This paper explores the biomedical model of mental illness, the symptoms of schizophrenia, various antipsychotic and antidepressant medications, their side effects, effects on the brain, and broader issues related to mental health treatment including social and ethical implications.

The biomedical model of mental illness posits that mental disorders are caused by abnormal biochemical processes in the brain. This perspective emphasizes genetic and neurobiological factors, suggesting that imbalances in neurotransmitters like dopamine and serotonin underpin psychiatric conditions (Insel, 2010). Evidence supporting this model includes genetic studies linking certain gene abnormalities with disorders such as schizophrenia and bipolar disorder (Schizophrenia Working Group of the Psychiatric Genomics Consortium, 2014). These findings have led to the development of psychotropic drugs aimed at correcting neurotransmitter imbalances.

Schizophrenia, one of the most studied mental disorders, is characterized by a disconnection from reality, often described as being “split off” or “broken off” from normal functioning. Its symptoms are classified as positive, negative, and cognitive. Positive symptoms include delusions—false beliefs that are resistant to reason—hallucinations, usually auditory, and disorganized speech. Negative symptoms comprise emotional blunting, anhedonia, and social withdrawal, while cognitive symptoms involve impairments in attention and executive functioning (Tandon et al., 2013). The hallucinations and delusions significantly impair the individual’s perception of reality and are key targets for pharmacological intervention.

The primary class of drugs used for schizophrenia are antipsychotics, which are categorized into first-generation (typical), second-generation (atypical), and third-generation (partial dopamine agonists). First-generation antipsychotics, such as Thorazine and Haldol, primarily block dopamine D2 receptors, reducing positive symptoms but often causing extrapyramidal side effects such as Parkinson-like symptoms and tardive dyskinesia (Kane et al., 2015). Second-generation drugs like Clozaril (clozapine), Zyprexa (olanzapine), and Risperdal (risperidone) target additional neurotransmitter systems, leading to fewer motor side effects but associated with weight gain, diabetes, and metabolic syndrome (Citrome, 2014). Third-generation antipsychotics, including Abilify (aripiprazole), act as partial D2 agonists, aiming to stabilize dopamine levels with potentially fewer adverse reactions (Meyer et al., 2014).

The side effects associated with antipsychotics are notable and often limit their long-term use. First-generation drugs have been linked with movement disorders such as tardive dyskinesia and Parkinsonian symptoms. Clozaril, while effective, carries risks of agranulocytosis, a potentially life-threatening reduction in white blood cells, requiring regular blood monitoring (Casey et al., 2014). The second-generation drugs have introduced metabolic side effects, including weight gain, dyslipidemia, and increased risk of diabetes, raising concerns over their safety profile, particularly for elderly patients and children (Correll et al., 2015).

Antipsychotics primarily influence dopamine-sensitive receptors across different regions of the brain. These drugs modulate dopamine activity, especially at the D2 receptor subtype, which is believed to be hyperactive in schizophrenia. The third-generation drugs aim to fine-tune this modulation by acting as partial agonists, reducing the likelihood of side effects while maintaining efficacy (Miller et al., 2014). Nevertheless, concerns remain about the long-term impact of these medications on brain structure and function, as some studies suggest potential adverse effects with prolonged use (Vieta & Mann, 2016).

The role of psychiatrists and the influence of the pharmaceutical industry have been scrutinized amid reports of overprescription, particularly among children. An example is Risperdal, prescribed off-label for conditions such as eating disorders and behavioral problems in children, raising ethical questions about clinical practices. The Food and Drug Administration (FDA) has documented increasing reports of serious side effects and fatalities among children using antipsychotics, with estimates possibly underrepresenting the true scope due to voluntary reporting systems (Harris et al., 2007). Critics argue that economic incentives and societal pressures contribute to the widespread use of these drugs, often without thorough evaluation of long-term risks (Geller et al., 2010).

Antidepressants, another major class of psychotropic drugs, target mood and anxiety disorders. First-generation antidepressants include monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants like Elavil and Tofranil, which increase neurotransmitter activity by inhibiting their breakdown or reuptake. Second-generation drugs, notably selective serotonin reuptake inhibitors (SSRIs) like Prozac and Zoloft, selectively raise serotonin levels, leading to improved mood with fewer side effects (Harmer et al., 2017). Third-generation antidepressants, such as Effexor and Remeron, combine actions on norepinephrine and serotonin to enhance efficacy (Keller et al., 2008). These medications work by modulating neurochemical pathways implicated in depression, but they often take weeks to produce noticeable benefits and may have side effects including sexual dysfunction and gastrointestinal disturbances.

Understanding the neurochemical basis of these medications highlights their capacity to adjust neurotransmitter functioning, which can alleviate depressive symptoms. However, they are not without limitations, as some patients do not respond adequately, prompting ongoing research into new treatments (Fava & Sonino, 2018). Moreover, the use of antidepressants and antipsychotics raises concerns about overmedication, especially in vulnerable populations such as children and the elderly, emphasizing the need for cautious and personalized treatment plans (García-Campayo et al., 2016).

In addition to medications, clinicians explore treatments for other mental disorders. For bipolar disorder, mood stabilizers such as Lithium and Depakote are used to control manic episodes. Autism spectrum disorders may be managed with drugs like Risperdal, which target behavioral symptoms (Asato et al., 2017). Mild depression can sometimes be treated with herbal remedies such as St. John’s wort, although caution is advised regarding interactions with other medications (Sarris et al., 2016). The overarching issues in mental health treatment extend beyond pharmacology and include social implications such as deinstitutionalization, which has shifted care from psychiatric hospitals to community settings, often resulting in inadequate support and increased homelessness among mentally ill populations (Lamb & Weinberger, 2018).

Furthermore, the impact of psychiatric drugs on civil liberties and personal autonomy remains a contentious topic, especially concerning involuntary treatment and medication compliance. Policy debates focus on balancing individual rights with societal safety, with some advocating for stricter regulations to prevent overreach while others emphasize the importance of accessible treatment options (Szmukler et al., 2014). The role of health insurance coverage also influences treatment accessibility and quality, often creating disparities in mental health care. Ensuring equitable and ethical treatment requires ongoing efforts to reform mental health policies, promote informed consent, and integrate psychosocial interventions with pharmacotherapy (Mechanic, 2018).
