Thiazide diuretics

Pooled trials found low-dose thiazides lowered blood pressure, stroke by about a third and deaths by 11%. The one large head-to-head trial found no difference in heart events between chlorthalidone and hydrochlorothiazide, with more low potassium on chlorthalidone. Hydrochlorothiazide was linked to a small rise in skin cancer, mainly squamous cell carcinoma.

Lowering blood pressure

Shown to lower blood pressure by dose, about 8/3 mm Hg on hydrochlorothiazide 25 mg and 12/4 mm Hg on chlorthalidone in adults with high blood pressure.

The numbers and sources
Effect
In 33 placebo-controlled trials, hydrochlorothiazide at 6.25, 12.5, 25 and 50 mg a day lowered blood pressure by 4/2, 6/3, 8/3 and 11/5 mm Hg. In 7 trials, chlorthalidone at 12.5 to 75 mg a day lowered it by 12.0/4 mm Hg, with no evidence that higher doses lowered it more [1]. A separate analysis of 354 trials found thiazides lowered blood pressure by about the same amount as the other main drug classes, on average 9.1/5.5 mm Hg at standard dose [2]. In stage 4 chronic kidney disease, chlorthalidone lowered 24-hour systolic pressure by 10.5 mm Hg more than placebo at 12 weeks (95% CI 6.4 to 14.6) [3].
Population
11,282 people in 60 trials of six thiazides, mean age 55, treated a mean 8 weeks [1]; about 40,000 treated and 16,000 placebo participants in 354 trials [2]; 160 people with stage 4 chronic kidney disease and poorly controlled hypertension [3].
Sources
[1], [2], [3]
Caveats
The chlorthalidone trials started from a different baseline pressure (163/88 against 155/100 mm Hg), so the two drugs' figures are not a direct comparison. Most trials were at unclear or high risk of bias [1].
Moderate

Heart attack, stroke and death

Shown to lower stroke from 6.2% to 4.2%, coronary heart disease from 3.9% to 2.8% and deaths from 11.0% to 9.8% as first-line low-dose treatment.

The numbers and sources
Effect
A Cochrane review found first-line low-dose thiazides lowered mortality (11.0% with control against 9.8%, RR 0.89, 95% CI 0.82 to 0.97), total cardiovascular events (12.9% against 9.0%, RR 0.70), stroke (6.2% against 4.2%, RR 0.68, 95% CI 0.60 to 0.77) and coronary heart disease (3.9% against 2.8%, RR 0.72). High-dose thiazides lowered stroke (RR 0.47) and total cardiovascular events (RR 0.72) and did not lower mortality [4]. In the SHEP trial of chlorthalidone-based treatment, the 5-year incidence of stroke was 5.2 per 100 on treatment and 8.2 on placebo (RR 0.64), with major cardiovascular events also lower (RR 0.68) [5]. In ALLHAT, chlorthalidone did not differ from amlodipine or lisinopril on fatal coronary disease or nonfatal heart attack, and had a lower 6-year rate of heart failure than either (7.7% against 10.2% and 8.7%) [6].
Population
58,040 people in 24 trials across drug classes, mean age 56, followed 3 to 5 years [4]; 4,736 adults aged 60 and over with isolated systolic hypertension, mean age 72 [5]; 33,357 adults aged 55 or older in ALLHAT [6].
Sources
[4], [5], [6]
Caveats
The Cochrane authors rated the low-dose evidence high quality and the high-dose evidence low to moderate [4]. The two named trials used chlorthalidone.
Moderate

Fractures

Linked to about 14% fewer fractures in cohort studies. In one randomized trial, chlorthalidone brought fewer hip and pelvic fractures than amlodipine or lisinopril.

The numbers and sources
Effect
In 11 cohort studies, thiazide users had fewer fractures of any kind than non-users (RR 0.86, 95% CI 0.80 to 0.93) and fewer hip fractures (RR 0.82). The effect was weaker in the higher-quality studies [15]. In a secondary analysis of ALLHAT, people randomized to chlorthalidone had fewer hip and pelvic fractures during the trial than those on amlodipine or lisinopril (HR 0.79, 95% CI 0.63 to 0.98). Over the trial plus later follow-up the difference was not significant (HR 0.87, 95% CI 0.74 to 1.03) [16].
Population
2,193,160 participants in 11 cohort studies [15]; 22,180 ALLHAT participants with a mean age of 70.4, followed up to 8 years in the trial [16].
Sources
[15], [16]
Caveats
The cohort studies are observational. The randomized evidence is a secondary analysis against other drugs, not placebo [16].

Mixed results2

Moderate

Chlorthalidone compared with hydrochlorothiazide

Mixed results: indirect comparisons favored chlorthalidone, and the one large head-to-head trial found no difference in heart events between the two.

The numbers and sources
Effect
In a pragmatic trial in adults 65 and older already on hydrochlorothiazide, a major cardiovascular event or non-cancer death occurred in 10.4% switched to chlorthalidone and 10.0% kept on hydrochlorothiazide over a median 2.4 years (HR 1.04, 95% CI 0.94 to 1.16) [7]. In a cohort of first-time users, the composite cardiovascular outcome did not differ (calibrated HR 1.00, 95% CI 0.85 to 1.17) [8]. Network meta-analyses that compared the drugs indirectly across separate trials found 21% fewer cardiovascular events on chlorthalidone (95% CI 12 to 28) [9], and 12% fewer on thiazide-like than thiazide-type diuretics after adjusting for blood pressure [10]. In 9 trials that compared them directly, chlorthalidone lowered systolic pressure by 3.26 mm Hg and diastolic by 2.41 mm Hg more [11].
Population
13,523 veterans with a mean age of 72 [7]; 730,225 first-time users in three US databases [8]; 9 trials with 50,946 people in the drug-adjusted analysis [9]; randomized trials of at least 1 year in adults with hypertension [10]; 9 head-to-head trials [11].
Sources
[7], [8], [9], [10], [11]
Caveats
In the head-to-head trial, 94.5% were taking hydrochlorothiazide 25 mg at entry and chlorthalidone was given at 12.5 or 25 mg [7]. The indirect comparisons do not randomize between the two drugs. For side effect differences, see the low potassium block below.
Moderate

Kidney stone prevention

Mixed results: a pooled analysis of 10 trials found 37% fewer stone recurrences on thiazides, and the largest trial found no difference from placebo.

The numbers and sources
Effect
A meta-analysis of 10 randomized trials found fewer stone recurrences on thiazides than placebo (RR 0.63, 95% CI 0.49 to 0.83), with substantial heterogeneity (I² 65%) [12]. In the largest trial, symptomatic or radiologic recurrence occurred in 59% on placebo and in 59%, 56% and 49% on hydrochlorothiazide 12.5, 25 and 50 mg, with no relation between dose and recurrence (P = 0.66) [13].
Population
650 people on thiazides and 672 on placebo in 10 trials [12]; 416 people with recurrent calcium-containing kidney stones followed a median 2.9 years [13].
Sources
[12], [13]
Caveats
The pooled trials are mostly older and smaller than [13]. Not an FDA-approved use [14].

Doses studied

The Cochrane review covered hydrochlorothiazide 6.25 to 50 mg a day and chlorthalidone 12.5 to 75 mg a day [1]. ALLHAT used chlorthalidone 12.5 to 25 mg a day [6]. The head-to-head trial compared hydrochlorothiazide 25 or 50 mg with chlorthalidone 12.5 or 25 mg a day [7]. The kidney stone trial used hydrochlorothiazide 12.5, 25 or 50 mg once daily [13], and the kidney disease trial used chlorthalidone from 12.5 mg up to 50 mg a day [3].

The chlorthalidone label gives a starting dose of 15 mg once daily for high blood pressure, raised to 25 mg if needed, and states that doses above 25 mg are not expected to lower blood pressure further [17].

Effect
Among men in a double-blind trial of five blood pressure drugs, erection problems through 24 months were reported by 17.1% on chlorthalidone and 8.1% on placebo (P = 0.025). Through 48 months the rates were more similar across groups. Reported sexual problems in women were infrequent and did not differ by drug [24].

The numbers and sources
How common
Common: between 1 in 100 and 1 in 10 people.
Effect
In the head-to-head trial, hypokalemia occurred in 6.0% on chlorthalidone and 4.4% on hydrochlorothiazide [7]. In a cohort of first-time users, hypokalemia was more frequent on chlorthalidone (HR 2.72, 95% CI 2.38 to 3.12) [8]. Across placebo-controlled trials, thiazides lowered potassium in a dose-related way, least with hydrochlorothiazide [1]. Hypokalemia was more frequent than on placebo in the kidney stone and kidney disease trials [13][3]. The hydrochlorothiazide label states that hypokalemia may cause cardiac arrhythmia and may heighten the heart's response to the toxic effects of digitalis [14].

The numbers and sources
How common
Common: between 1 in 100 and 1 in 10 people.
Effect
In a Danish cohort, the 2-year cumulative incidence of sodium below 130 mmol/L was 3.51% in new users of hydrochlorothiazide combined with a renin-angiotensin drug, 1.38 percentage points more than on the renin-angiotensin drug alone (95% CI 1.01 to 1.75). For bendroflumethiazide it was 3.83%, 1.35 points more than on a calcium channel blocker. The excess was largest in the first 30 days (HR 4.25 and 3.56) and rose with age and illness [18]. In a US cohort, hyponatremia was more frequent on chlorthalidone than on hydrochlorothiazide (HR 1.31, 95% CI 1.16 to 1.47) [8].
Population
11,943 new users of hydrochlorothiazide with a renin-angiotensin drug and 85,784 of the renin-angiotensin drug alone, and 37,786 new users of bendroflumethiazide against 44,963 of a calcium channel blocker, all aged 40 or older [18]; 730,225 first-time users [8].

Shown to bring more new diabetes than placebo or other blood pressure drugs, with placebo carrying about 23% lower odds than a diuretic.

The numbers and sources
How common
Common: between 1 in 100 and 1 in 10 people.
Effect
In a network meta-analysis of 22 trials with a diuretic as the reference, the odds of new diabetes were lower on placebo (OR 0.77, 95% CI 0.63 to 0.94), ARBs (0.57), ACE inhibitors (0.67) and calcium channel blockers (0.75), and not significantly different on beta-blockers (0.90). Diabetes developed in 998 of 18,699 people (5.34%) started on a diuretic [20]. In placebo-controlled trials, chlorthalidone raised serum glucose, and the evidence was unclear for other thiazides [1]. New diabetes was more frequent on chlorthalidone than hydrochlorothiazide in a cohort (HR 1.21, 95% CI 1.12 to 1.30) [8]. The label states that hyperglycemia may occur and latent diabetes may become manifest [14].

Skin cancer with hydrochlorothiazide

Linked to more non-melanoma skin cancer, mainly squamous cell carcinoma, rising with cumulative dose. The label puts the excess at about 1 case per 16,000 people a year.

The numbers and sources
How common
Rare: fewer than 1 in 1,000 people.
Effect
In a Danish case-control study, cumulative use of 50,000 mg or more was associated with basal cell carcinoma (OR 1.29, 95% CI 1.23 to 1.35) and squamous cell carcinoma (OR 3.98, 95% CI 3.68 to 4.31), rising to 1.54 and 7.38 at 200,000 mg or more. Other diuretics and blood pressure drugs were not associated [21]. A meta-analysis found hydrochlorothiazide associated with non-melanoma skin cancer (OR 1.16, 95% CI 1.08 to 1.24), squamous cell carcinoma (OR 1.32) and melanoma (OR 1.11) [22]. A second, of 30 non-randomized studies of thiazides, found associations with squamous cell carcinoma (OR 1.35, 95% CI 1.22 to 1.48), basal cell carcinoma (OR 1.05), melanoma (OR 1.10) and lip cancer (OR 1.92) [23]. The label states that in an FDA Sentinel study the increased risk was mainly for squamous cell carcinoma and in white patients taking large cumulative doses: about 1 additional case per 16,000 patients a year overall, and 1 per 6,700 a year in white patients with 50,000 mg or more [14].

Linked to more acute kidney injury when an NSAID is taken with both a diuretic and an ACE inhibitor or ARB. The label says NSAIDs can blunt the diuretic.

The numbers and sources
How common
Rare: fewer than 1 in 1,000 people.
Effect
Among users of blood pressure drugs, an NSAID with both a diuretic and an ACE inhibitor or ARB was associated with a higher rate of acute kidney injury (rate ratio 1.31, 95% CI 1.12 to 1.53), highest in the first 30 days (1.82). An NSAID with a diuretic alone was not associated with a higher rate. Acute kidney injury occurred at 7 per 10,000 person-years in the cohort [26]. The hydrochlorothiazide label states that NSAIDs can reduce the diuretic and blood pressure effects of thiazides [14].

Effect
The hydrochlorothiazide label states that diuretics reduce the kidney's clearance of lithium and add a high risk of lithium toxicity [14]. In a study of older adults on lithium, thiazide diuretics were not independently associated with a significant rise in hospital admission for lithium toxicity, while loop diuretics (RR 5.5) and ACE inhibitors (RR 7.6) were [25].

Claims tested and not found

  1. That chlorthalidone prevents more heart attacks and strokes than hydrochlorothiazide. In 13,523 adults aged 65 and older, a major cardiovascular event or non-cancer death occurred in 10.4% on chlorthalidone and 10.0% on hydrochlorothiazide (HR 1.04, 95% CI 0.94 to 1.16) [7].
  2. That hydrochlorothiazide prevents kidney stones from coming back. In 416 people with recurrent calcium stones, recurrence at 12.5, 25 and 50 mg did not differ from placebo, and there was no dose-response [13].
  3. That people allergic to sulfa antibiotics react to non-antibiotic sulfa drugs, the group hydrochlorothiazide belongs to, because the drugs cross-react. Among people with a prior reaction to a sulfonamide antibiotic, 9.9% reacted to a sulfonamide nonantibiotic against 1.6% of those without (adjusted OR 2.8). The same people were even more likely to react to penicillin (adjusted OR 3.9), and the authors reported an absence of cross-reactivity between the two sulfonamide groups [27].
  4. That higher chlorthalidone doses lower blood pressure more. Across trials of 12.5 to 75 mg a day, direct comparison of doses showed no dose dependence for blood pressure lowering [1].
