What is known and Objectives: A problem that often affects antihypertensive drugs is the lack of formulations appropriate for childhood. Parents, therefore, crush tablets and administer the antihypertensive drug mixed with solid food or a palatable drink. Because palatability is a major modulator of adherence to prescribed medication, the palatability of crushed β-blockers, converting enzyme inhibitors and thiazides was assessed among adult volunteers. Methods: The palatability of crushed atenolol, bisoprolol, enalapril, lisinopril, ramipril, chlorthalidone and hydrochlorothiazide was evaluated by means of a facial hedonic scale among 20 volunteers. The calcium channel-blockers amlodipine and lercanidipine whose tastes are disliked and liked, respectively, by children were also tested. A concealed random allocation procedure was used. Results: The palatability scores assigned to chlorthalidone, hydrochlorothiazide and lisinopril were superior (P <0.002) to those assigned to atenolol, bisoprolol, enalapril and ramipril. As with children, the palatability score of lercanidipine was superior to that of amlodipine (P <0.002). The scores assigned to the various agents were similar in women and in men and were age-independent. What is new and Conclusion: Pulverized atenolol, bisoprolol, enalapril and ramipril are poor tasting. From the perspective of palatability, pulverized chlorthalidone, hydrochlorothiazide and lisinopril are preferable.
