Patients are more likely to take their medication when it is combined into a fixed dose combination (FDC). However, the irrational use of FDCs poses serious risks to public health. Knowledge of how to prescribe FDCs is crucial, as residents play a pivotal role in patient management at tertiary care facilities. From February 2016 to July 2016, a cross-sectional observational study was carried out at tertiary care centre in Central India. Hypertensive patients taking anti-hypertensive fixed-dose combinations (FDCs) were recruited for the study; 92 prescriptions met the inclusion and exclusion criteria and were included in the trial. Nonetheless, 53 percent of the medical professionals lacked understanding about the efficacy of specific FDCs. Textbooks and scholarly periodicals were the usual go-tos for research. Seventy-three percent of locals surveyed thought FDCs should be legally sold. According to the doctors' estimates, antimicrobial FDCs, specifically amoxicillin + clavulanic acid, account for the vast majority of prescriptions. Using a piloted questionnaire, researchers in Jammu conducted a cross-sectional study at a university-affiliated medical centre (Jammu and Kashmir). In order to gauge respondents' FDC-related KAP, a questionnaire was developed. Researchers included physicians from the Departments of Medicine, Obstetrics and Gynecology, Surgery, Pediatrics, Skin, and Psychiatry who were employed at the hospital during the study period and who provided written informed permission. Appropriate statistical tests were used to assess the data
