Hamad Bin Khalifa University (HBKU)’s College of Health and Life Sciences (CHLS) has published in the Journal of Personalized Medicine the findings of a joint study on antidepressant prescription patterns and off-label use in the Qatari population.
Dr. Puthen V. Jithesh, associate professor at CHLS, worked with Dr. Kholoud Bastaki, the first Qatari to graduate from the PhD program in Genomics and Precision Medicine at CHLS and the first author of the paper; researchers from Sidra Medicine; and Hamad Medical Corporation’s Mental Health Services, to conduct a retrospective database study of Qatari patients prescribed antidepressants between June 2018 and May 2020. According to the paper, studying the prescription pattern of medications will help in identifying potential unnecessary prescriptions and support the need for personalized medicine.
Evidence indicates that genetic factors play an important role in determining differences in patient responses to antidepressants and associated adverse effects. In a soon-to-be-published related study, Dr. Jithesh used whole genome sequencing data to investigate drug-related genetic variation in the adult Qatari population. The findings identified a high prevalence of variation in two genes which are important in the metabolism of several antidepressants. The results further highlight the need to implement pharmacogenomics tests to support personalized prescriptions, dosage adjustments, or alternate drugs for more efficient treatment.
Dr. Edward Stuenkel, founding dean of CHLS, said: “Population-level prescription trends, as reported in the study, when combined with patient genetic variability and outcome data, will enable clinicians to predict the potential treatment failures and adverse effects of these antidepressant medications in the population. The data is important in making informed decisions on the need to implement pharmacogenomic testing in Qatar, and engaging policy makers to understand usage and develop evidence-based guidelines for more efficient treatment options.”
