| Thiazide diuretics, such as chlorothiazide and hydrochlorothiazide, may be excreted unchanged in the urine. |
| Pharmacologic agents used have included hydrochlorothiazide, spironolactone, furosemide, propranolol, or hydralazine. |
| Patients usually do not require doses in excess of 50 mg of hydrochlorothiazide daily, particularly when combined with antihypertensive agents. |
| Treatment with long-acting nifedipine failed to lower her pressure, so atenolol, then hydrochlorothiazide, and finally lisinopril were added. |
| None of these studies showed any evidence of teratogenic effects of hydrochlorothiazide. |
| Chlorothiazide and hydrochlorothiazide are effective both as diuretics and in reducing blood pressure. |
