This study analyzed drug prescribing patterns for urinary tract infections (UTIs) among patients aged 12–80 years, male and female and assessed drug use in such cases. Comprised a quantitative, drug prescribing observational study and employed more than 90 confirmed cases of UTIs. The specimens investigated were collected from different hospitals in the Najran Region of the Kingdom of Saudi Arabia (KSA) and the Stokes technique was used to observe the sensitivity pattern of the isolates. The analyses showed 90.0% of total isolated organisms were Gram-negative bacteria. Among the Gram-negative and Gram-positive bacteria, Escherichia coli and Staphylococcus epidermis were the most prevalent organisms, respectively. The percentage of Gram-negative isolates was found to be the greatest for E. coli (54.83%), followed by Klebsiella (9.67%) and Sphingomonnus paucimobilis (5.37%). Among the Gram-positive isolates, the greatest occurrence was found for Staphylococcus epidermis (5.37%). The antibiotic effectiveness against different isolates was found to be greatest for Amikacin (95.2%), followed by Ceftriaxone (89.3%), Ceftazidime (88.1%) and Ciprofloxacin (84.5%). Furthermore, screening of multi-drug resistant isolates for extended-spectrum beta (?)-lactamase (ESBL) production showed that 58.33% of Gram-negative isolates produce these enzymes. Among the various bacteria, the production of EDSL enzymes was greatest for E. coli (72.54%), followed by Klebsiella and Pseudomonas aeruginosa (both 66.66%) and then Sphingomonnus paucimobilis (40.0%). The findings suggest that antibiotic resistance in UTIs shows alarming outcomes and clinical guidelines are urgently required to minimize resistance to antibiotics for the treatment of UTIs in the Najran Region, KSA.
