A recent study showed the benefits of Chlorthalidone, and old-time diuretic, in treated elevated blood pressure.
Systolic hypertension (top number high blood pressure) is common as we age and often is difficult to treat adequately. Inexpensive diuretics are particularly good for this issue, but results may seem inadequate with little drop in the blood pressure number.
Despite this, using this diuretic provide statistically significant reduction in hypertension complications.
