Keywords: Diuretics; Hypertension; Hydrochlorothiazide; Indapamide; Guidelines Introduction Diuretics represent a large and heterogeneous class of drugs, differing from each other by structure, site and mechanism of action. Diuretics are widely used, and have several indications in different cardiovascular disorders, particularly in hypertension and heart failure. Despite the large number of available anti-hypertensive drugs, diuretics remained a cornerstone of hypertension treatment [1]. Indeed, they are the second most commonly prescribed class of antihypertensive medication. For instance, 12% of US adults were prescribed a diuretic, and the relative increase in prescriptions from 1999 through 2012 was 1.4 [2].

  • Approach to Managing Patients with Sulfa Allergy Use of Antibiotic and Nonantibiotic Sulfonamides
    CME Approach to managing patients with sulfa allergy Use of antibiotic and nonantibiotic sulfonamides David Ponka, MD, CCFP(EM) ABSTRACT OBJECTIVE To present an approach to use of sulfonamide-based (sulfa) medications for patients with sulfa allergy and to explore whether sulfa medications are contraindicated for patients who require them but are allergic to them. SOURCES OF INFORMATION A search of current pharmacology textbooks and of MEDLINE from 1966 to the present using the MeSH key words “sulfonamide” and “drug sensitivity” revealed review articles, case reports, one observational study (level II evidence), and reports of consensus opinion (level III evidence). MAIN MESSAGE Cross-reactivity between sulfa antibiotics and nonantibiotics is rare, but on occasion it can affect the pharmacologic and clinical management of patients with sulfa allergy. CONCLUSION How a physician approaches using sulfa medications for patients with sulfa allergy depends on the certainty and severity of the initial allergy, on whether alternatives are available, and on whether the contemplated agent belongs to the same category of sulfa medications (ie, antibiotic or nonantibiotic) as the initial offending agent. RÉSUMÉ OBJECTIF Proposer une façon d’utiliser les médicaments à base de sulfamides (sulfas) chez les patients allergiques aux sulfas et vérifier si ces médicaments sont contre-indiqués pour ces patients. SOURCES DE L’INFORMATION Une consultation des récents ouvrages de pharmacologie et de MEDLINE entre 1966 et aujourd’hui à l’aide des mots clés MeSH «sulfonamide» et «drug sensitivity» a permis de repérer plusieurs articles de revue et études de cas, une étude d’observation et des rapports d’opinion consensuelles (preuves de niveau III).

  • Diuretics for Hypertension
    The Rx Files: Q&A Summary March 1998, LDR DIURETICS IN THE TREATMENT OF HYPERTENSION: CURRENT STATUS 1. When are thiazide diuretics considered first line antihypertensives? Antihypertensive therapy should be individualized by choosing agents that have favorable effects on comorbid conditions. The recent JNC VI report1 recommends thiazides (or â Blockers) as first line agents in the treatment of uncomplicated hypertension except where contraindicated, not tolerated, or concurrent medical conditions favor use of alternate agents (see Appendix 1).1 Thiazide diuretics and â Blockers are the only antihypertensives that have been well documented in long-term controlled trials to reduce cardiovascular morbidity and mortality, particularly MI and stroke.2 Current large-scale trials are underway to determine if other classes of antihypertensives have similar benefits. Thiazides are particularly effective in elderly patients with isolated systolic hypertension.1 They also have favorable effects in patients at risk of osteoporosis. When not used for initial monotherapy, addition of a low dose diuretic as the second agent is recommended unless contraindicated.1 2. Are low dose thiazides as effective in treating hypertension as higher doses? Doses as low as 12.5-25mg of hydrochlorothiazide (HCT), given once daily, have been as effective in lowering blood pressure as higher doses.3 In fact, doses above 25mg have little added benefit but greater incidence of adverse effects.3,7 A dose of 6.25mg HCT can often significantly augment the response of other antihypertensives when used in combination. 3. What about the adverse metabolic effects of thiazides? In doses of 25mg or less, incidence of hypokalemia is <5%, and few patients will actually require potassium supplementation or addition of a K+ sparing diuretic.
