Chlorothiazide sodium (Diuril) is an organic compound used as a diuretic and as an antihypertensive.[1]
It is used both within the hospital setting or for personal use to manage excess fluid associated with congestive heart failure. Most often taken in pill form, it is usually taken orally once or twice a day. In the ICU setting, chlorothiazide is given to diurese a patient in addition to furosemide (Lasix). Working in a separate mechanism than furosemide, and absorbed enterically as a reconstituted suspension administered through a nasogastric tube (NG tube), the two drugs potentiate one another.
Indications
- Large amount of excess fluid including:
- Diagnosed congested heart failure
- Peripheral edema
- Rales / Rhonchi
- Hypertension
Contraindications
- Renal failure or insufficiency
- Allergies to sulfa drugs
Side effects
- Nausea / Vomiting
- Headache
- Dizziness
- Excess urine production
- Dehydration
- Hypoelectrolytemia (esp. hypokalemia / hypomagnesia)
History
The Research team of Merck Sharp and Dohme Research Laboratories of Beyer, Sprague, Baer, and Novello created a new series of medications, the thiazide diuretics, which includes chlorothiazide. They won an Albert Lasker Special Award in 1975 for this work.[2]
