Abstract

The distribution of N-acetyltransferase-2 (NAT2) genetic polymorphisms varies across ethnic groups among Indonesian TB patients. This review aimed to provide a comprehensive understanding of the prevalence of NAT2 genetic polymorphisms and their association with DILI and isoniazid pharmacokinetics in Indonesian TB patients. A scoping review was conducted by searching Google Scholar, Scopus, and PubMed in accordance with PRISMA guidelines for scoping review (PRISMA-ScR). We retrieved 668 studies from three databases and we enrolled 12 studies for final analysis. Eleven studies reported on adult TB patients and one study on pediatric TB patients. Overall, the available evidence suggests that the slow acetylator phenotype is relatively common among TB patients in Indonesia, although its distribution varies across regions and ethnic groups. The NAT2*6 polymorphism was frequently observed among TB patients with a slow acetylator phenotype. TB patients with slow acetylation exhibited higher serum concentrations of isoniazid, which were significantly associated with an increased risk of DILI. No studies reported an association between NAT2 genetic polymorphisms or acetylation status and treatment outcomes among TB patients. This review confirms substantial variation in NAT2 genetic polymorphisms across studies in Indonesia. TB patients with a slow acetylator phenotype appear to have a greater risk of developing DILI compared with those with intermediate or fast acetylator phenotypes. Information on acetylator status may identify patients at higher risk of hepatotoxicity, particularly those with the slow acetylator phenotype. Therefore, integrating NAT2 pharmacogenetics into clinical practice may predict hepatotoxicity and optimize tuberculosis therapy.

Abstract

Introduction: Schizophrenia is a chronic mental disorder with a rising prevalence, including in East Nusa Tenggara. Antipsychotics are the mainstay therapy, but prescribing patterns in primary care vary depending on patient condition and drug response. This study aimed to describe the prescribing patterns of antipsychotics among schizophrenia patients at Sikumana and Oesapa Primary Health Centers, Kupang City.Methods: A non-experimental descriptive design was applied using retrospective data from medical records of schizophrenia patients (ICD-X F20) during February–July 2025. Inclusion criteria consisted of patients who received antipsychotic therapy at both of two Primary Health Centers. Exclusion criteria included patients referred to higher-level facilities before receiving antipsychotic treatment.Results: A total of 42 patients with 129 visits were analyzed, dominated by males (52.4%) and the 25–44 age group (59.5%). Most were chronic patients (88.1%). Of 129 prescriptions, monotherapy predominated (57.4%), dominated by haloperidol (45 times) and risperidone (21 times). Combination therapy was also common (42.6%), particularly chlorpromazine + risperidone (29 times) and chlorpromazine + haloperidol (24 times). Trihexyphenidyl (103 times) was frequently prescribed as prophylaxis against extrapyramidal side effects, while diazepam (17 times) was used for anxiety or sleep disturbances. Several drugs were prescribed at lower doses than national and international guidelines, reflecting stable patient conditions in primary care, where lower doses remained effective while minimizing adverse effects.Conclusion: These findings highlight the dominance of typical antipsychotics and the limited variety of available drugs in primary care, underscoring the need for broader drug availability and more systematic monitoring of side effects.
