Antidiabeticdrugs seen frequently prescribed are biguanides (34.36%). A total of 167 possible DDIs were obtained. Angiotensin-converting enzyme inhibitors weremost frequently involved antihypertensive drug in DDIs, with 60 of all possible DDIs identified. Insulin and biguanides were most frequently involvedantidiabetic drugs in DDIs, with 58 each of all possible DDIs identified. Most frequently interacting drug pair was insulin + metformin (n=19).Conclusion: For every possible DDIs found in the prescription, the appropriate intervention was advised from the investigator's part as well asprovision for a physician to review and initiate modification of his choice.Keywords: Hypertension, Possible drug-drug interaction, Type 2 diabetes mellitus.Â
