Résumé (en anglais)
IMPORTANCE: Deprescribing of antihypertensive medications is recommended for some older patients with polypharmacy and multimorbidity when the benefits of continued treatment may not outweigh the harms.
OBJECTIVE: This study aimed to establish whether antihypertensive medication reduction is possible without significant changes in systolic blood pressure control or adverse events during 12-week follow-up.
DESIGN, SETTING, AND PARTICIPANTS: The Optimising Treatment for Mild Systolic Hypertension in the Elderly (OPTIMISE) study was a randomized, unblinded, noninferiority trial conducted in 69 primary care sites in England. Participants, whose primary care physician considered them appropriate for medication reduction, were aged 80 years and older, had systolic blood pressure lower than 150 mm Hg, and were receiving at least 2 antihypertensive medications were included. Participants enrolled between April 2017 and September 2018 and underwent follow-up until January 2019.
INTERVENTIONS: Participants were randomized (1:1 ratio) to a strategy of antihypertensive medication reduction (removal of 1 drug [intervention], n = 282) or usual care (control, n = 287), in which no medication changes were mandated.
MAIN OUTCOMES AND MEASURES: The primary outcome was systolic blood pressure lower than 150 mm Hg at 12-week follow-up. The prespecified noninferiority margin was a relative risk (RR) of 0.90. Secondary outcomes included the proportion of participants maintaining medication reduction and differences in blood pressure, frailty, quality of life, adverse effects, and serious adverse events.
RESULTS: Among 569 patients randomized (mean age, 84.8 years; 276 [48.5%] women; median of 2 antihypertensive medications prescribed at baseline), 534 (93.8%) completed the trial. Overall, 229 (86.4%) patients in the intervention group and 236 (87.7%) patients in the control group had a systolic blood pressure lower than 150 mm Hg at 12 weeks (adjusted RR, 0.98 [97.5% 1-sided CI, 0.92 to 8]). Of 7 prespecified secondary end points, 5 showed no significant difference. Medication reduction was sustained in 187 (66.3%) participants at 12 weeks. Mean change in systolic blood pressure was 3.4 mm Hg (95% CI, 1.1 to 5.8 mm Hg) higher in the intervention group compared with the control group. Twelve (4.3%) participants in the intervention group and 7 (2.4%) in the control group reported at least 1 serious adverse event (adjusted RR, 1.72 [95% CI, 0.7 to 4.3]).
CONCLUSIONS AND RELEVANCE: Among older patients treated with multiple antihypertensive medications, a strategy of medication reduction, compared with usual care, was noninferior with regard to systolic blood pressure control at 12 weeks. The findings suggest antihypertensive medication reduction in some older patients with hypertension is not associated with substantial change in blood pressure control, although further research is needed to understand long-term clinical outcomes.

General Internal Medicine-Primary Care(US)
An interesting early and lower-quality validation of the primary care "sense" for when anti-hypertensive poly-pharmacy may be overburdening patients. A better understanding of how patients were identified would be interesting and lead to better actualizable evidence.

The comorbidity in this age group from falls or loss of balance is significant and at times results in fracture or ICB and death, so it is important to pay attention to this and address it. People get left on their meds for years without asking the question: Are we overdoing this for no benefit?
Geriatrics
De-prescribing was once viewed as taboo in medicine, but in an era of over-diagnosis and its corresponding over-treatment, this concept is gaining momentum in geriatrics. This RCT provides compelling proof that reducing blood pressure medication burden is safe in older adults.
Geriatrics
This is an important article post-SPRINT that was not universally applicable to the elderly.
Internal Medicine
Although variables such as the class of medication removed have presumed significant effects on the elevation of blood pressure occurring from removal, this study suggests that with age, the medications are likely contributing little to overall blood pressure control. As is done in the US, a higher blood pressure target may be reasonable and safely achieved with single-agent removal.
Internal Medicine
Interesting short-term follow-up results.

Finally, an RCT about de-prescribing!
