Altizide is a diuretic medication that is typically used to treat hypertension or high blood pressure. The medication works by increasing the production of urine and helping the body to eliminate excess salt and water. Some common synonyms for altizide include hydrochlorothiazide, chlorthalidone, and indapamide. These medications work in a similar way to altizide and are often used interchangeably. They all belong to the same class of drugs known as thiazide diuretics. It is important to note that while these medications have similar effects, they may not be suitable for everyone, and the choice of medication should be made in consultation with a healthcare professional.
