Single-Pill Combination Product Availability of the Antihypertensive Regimens Used for Intensive Systolic Blood Pressure Treatment in the Systolic Blood Pressure Intervention Trial

Originally published8 Jun 2023https://doi.org/10.1161/HYPERTENSIONAHA.123.21132Hypertension. 2023;80:1749–1758

    Abstract

    BACKGROUND:

    Single-pill combination (SPC) antihypertensive products improve blood pressure control and medication adherence among patients with hypertension. It is unknown to what degree commercially available SPC products could be used to target an intensive systolic blood pressure goal of <120 mm Hg.

    METHODS:

    This cross-sectional analysis included participants randomized to the intensive treatment arm (goal systolic blood pressure <120 mm Hg) of the Systolic Blood Pressure Intervention Trial (SPRINT) using ≥2 antihypertensive medication classes at the 12-month postrandomization visit. Antihypertensive medication data were collected using pill bottle review by research coordinators, and regimens were categorized by the unique combinations of antihypertensive classes. We calculated the proportion of regimens used, which are commercially available as one of the 7 SPC class combinations in the United States as of January 2023.

    RESULTS:

    Among the 3833 SPRINT intensive arm participants included (median age, 67.0 years; 35.5% female), participants were using 219 unique antihypertensive regimens. The 7 regimens for which there are class-equivalent SPC products were used by 40.3% of participants. Only 3.2% of all medication class regimens used are available as a class-equivalent SPC product (7/219). There are no SPC products available with 4 or more medication classes, which were used by 1060 participants (27.7%).

    CONCLUSIONS:

    Most SPRINT participants in the intensive arm used an antihypertensive medication regimen, which is not commercially available as a class equivalent SPC product. To achieve the SPRINT results in real-world settings, maximize the potential benefit of SPCs, and reduce pill burden, improvements in the product landscape are needed.
