Pharmacological treatment involves administering medications to manage symptoms and underlying conditions of patients. Proper medication dosing, administration, and nursing recommendations are essential for ensuring safety and efficacy. For a patient diagnosed with schizophrenia and concurrent anxiety, especially when substance use like drugs, alcohol, and smoking is involved, tailored pharmacological interventions are critical. This paper discusses medications typically used in managing schizophrenia and anxiety, their dosing guidelines, nursing considerations, and appropriate recommendations for such a complex case.

Schizophrenia is primarily managed with antipsychotic medications, which can be classified as typical (first-generation) or atypical (second-generation). Atypical antipsychotics, such as olanzapine, risperidone, quetiapine, and aripiprazole, are preferred due to fewer extrapyramidal side effects and improved efficacy in treating both positive and negative symptoms of schizophrenia (Miyamoto et al., 2012). The initial dosing of atypical antipsychotics varies depending on the specific medication, patient age, health status, and concurrent substance use. For instance, olanzapine is often started at 5 to 10 mg once daily, with titration up to a maintenance dose between 10 and 20 mg per day (Zheng et al., 2019). Risperidone is typically initiated at 1 mg twice daily, titrated cautiously based on response and side effects, with a usual dose of 4 to 6 mg daily (Leucht et al., 2013). Nursing recommendations emphasize monitoring for metabolic side effects such as weight gain, hyperglycemia, and dyslipidemia, especially given the patient's co-occurring substance use, which exacerbates metabolic risks.

Management of anxiety in schizophrenia patients commonly involves medications such as benzodiazepines, including lorazepam, alprazolam, or diazepam. Lorazepam, for example, is generally prescribed at 0.5 to 2 mg two to three times daily, with adjustments based on clinical response and sedation risk (Patil et al., 2020). Due to potential for dependence and respiratory depression, especially in a patient with substance use issues, the use of benzodiazepines should be cautious and closely monitored. Nursing considerations involve assessing for signs of sedation, respiratory depression, and potential misuse. Non-pharmacological interventions, such as cognitive-behavioral therapy, are recommended adjuncts to medication to address underlying anxiety and substance use behaviors (Hofmann et al., 2012).

Regarding medication administration, ensuring adherence is crucial in patients with schizophrenia and substance use disorder. Nurses should encourage patient education about medication purpose, potential side effects, and the importance of regular intake to prevent relapse. In patients with alcohol and drug use, periodic assessment of liver function tests and toxicology screening are pertinent. Given variable pharmacokinetics in alcohol and drug users, dosage adjustments may be necessary, and medication efficacy must be regularly evaluated through clinical assessment and patient feedback. Nursing recommendations also include fostering a supportive therapeutic environment, managing side effects proactively, and coordinating care with mental health specialists to optimize outcomes.

Managing pharmacological treatment in patients with schizophrenia complicated by substance use requires a comprehensive understanding of medication properties, dosing protocols, and nursing considerations. The primary goal is symptom stabilization, prevention of relapse, and addressing co-morbidities like anxiety and substance dependency.

Antipsychotic medications are at the cornerstone of schizophrenia management. Atypical antipsychotics have become preferred choices due to their favorable side effect profiles and efficacy. Olanzapine, for instance, provides effective control of positive and negative symptoms at start doses of 5–10 mg daily, with titration based on response and tolerability (Zheng et al., 2019). Risperidone, another effective atypical, begins at 1 mg BID and can be titrated upward to 4–6 mg daily, with careful monitoring for extrapyramidal symptoms and prolactin elevation (Leucht et al., 2013). Nurses play a vital role in monitoring for adverse effects such as weight gain, metabolic syndrome, and extrapyramidal symptoms, especially in patients with co-morbid substance use, which may increase the risk of adverse outcomes.

In managing anxiety in these patients, benzodiazepines such as lorazepam are frequently used for short-term relief. Lorazepam is administered at 0.5–2 mg two to three times daily, and titrated cautiously to mitigate risks associated with dependence, sedation, and respiratory depression (Patil et al., 2020). For patients with a history of substance use, benzodiazepine use warrants close supervision, considering their potential for abuse. Alternative therapies, including psychotherapy and non-pharmacologic approaches, are valuable adjuncts and should be integrated into the overall treatment plan (Hofmann et al., 2012).

Given the patient's substance use history, medication management becomes more complex. Alcohol and drug use impact hepatic metabolism and drug absorption, necessitating individualized dosing and vigilant monitoring. Nurses should routinely assess for medication adherence, side effects, and signs of relapse or intoxication. Encouraging patient education about medication purposes, potential side effects, and the importance of abstinence from substances helps enhance compliance and health outcomes. Additionally, interdisciplinary collaboration with mental health professionals, substance abuse counselors, and primary care providers is essential to developing a holistic treatment plan addressing both psychiatric and substance use disorders.

Long-term management also involves addressing social determinants of health, such as housing, employment, and social support, which significantly influence treatment adherence and recovery. Community-based interventions and holistic care approaches are vital for this cohort, with medications serving as just one component of a comprehensive treatment strategy (Sunderland et al., 2018). Continual assessment and adjustments based on patient response, side effects, and evolving needs are fundamental to effective treatment of schizophrenia with co-occurring substance use and anxiety.
