Objective: to analyze the influence of drug intervention on the clinical efficacy of hypertension patients. Methods: 98 patients with diabetes and hypertension admitted from April 2020 to April 2022 were randomly divided into observation group and control group. 49 patients in the control group used routine pharmaceutical guidance while reducing blood pressure and glucose, and 49 patients in the observation group strengthened pharmaceutical intervention while reducing blood pressure and glucose. The comprehensive management effect of the two groups of patients was observed, including the score of medication knowledge, the effect of blood pressure and glucose control, medication compliance adverse drug reactions and management satisfaction rate. Results: the scores of diabetes and hypertension medication knowledge were improved in both groups, and after interventional treatment, the observation group was significantly higher than the normal group (P < 0.05);Results: the systolic blood pressure, diastolic blood pressure, fasting blood glucose and 2h postprandial blood glucose of the two groups were significantly lower than those of the control group (P<0.05);The observation group had good drug compliance, less side effects after treatment, and the management satisfaction after treatment was significantly better than that of the control group. There was statistical significance in different data analysis (P<0.05). Conclusion: strengthening pharmaceutical intervention in the treatment of type 2 diabetes complicated with hypertension is of great significance to improve the drug knowledge and overall effect of clinical pharmacists, ensure drug compliance, use safety and improve the service quality of pharmacies. 展开更多
