Insights
Citalopram, an antidepressant, significantly lowered blood pressure in patients with both hypertension and depression. This study suggests citalopram may be a beneficial addition to standard hypertension treatment.
Area of Science:
- Cardiovascular Medicine
- Psychiatry
- Pharmacology
Background:
- Hypertension and depression share a bidirectional relationship.
- Managing both conditions concurrently presents unique challenges.
Purpose of the Study:
- To investigate the efficacy of citalopram in managing hypertension in patients with comorbid depression.
- To assess the impact of citalopram on blood pressure levels in this patient population.
Main Methods:
- A randomized clinical trial involving 72 patients with hypertension and depression.
- Intervention group received citalopram (20 mg/day) plus standard antihypertensive treatment.
- Control group received standard antihypertensive treatment alone.
Main Results:
- After two months, the intervention group showed significant reductions in both systolic and diastolic blood pressure compared to the control group.
- Diastolic blood pressure was significantly lower in the citalopram group after one month.
- No significant baseline differences in blood pressure were observed between groups.
Conclusions:
- Citalopram demonstrated beneficial effects in lowering blood pressure in patients with co-occurring depression and hypertension.
- This suggests a potential role for citalopram as an adjunct therapy for hypertension in depressed patients.
Introduction:
Since there is a bi-directional interaction between hypertension and depression, we aimed to evaluate the effects of citalopram administration in the management of hypertension.
Methods:
A randomized clinical trial was conducted on 72 patients with concomitant depression and hypertension. The intervention group (n=41) received citalopram 20 mg daily plus anti-hypertensive standard treatment, while the control group (n=31) received only the standard treatment. The study's primary endpoint was in-office blood pressure (BP) measurement at baseline and home BP monitoring in the first and second months after entering the study.
Results:
There were no significant differences in baseline systolic BP (163.3±19.6 vs.164.2±20.3 mm Hg; P=0.910) and diastolic BP (94.5±13.8 vs. 88.2±14.4; P=0.071). After one month, diastolic BP (82.7±11.7 vs. 77.09±12.2; P=0.023) was significantly higher in the control group compared to the intervention group. Two months after the intervention, systolic BP (133.8±16.5 vs. 124.5±12.4; P=0.009) and diastolic BP (80.7±10.3 vs. 73.7±9.7; P=0.002) were significantly decreased in the intervention group compared to the control group.
Conclusion:
This study supported the beneficial effects of citalopram in lowering BP in patients with concomitant depression and hypertension.
