The pill described as "h126 yellow oval" is likely hydrochlorothiazide [1]. Hydrochlorothiazide is a thiazide diuretic medication used to treat high blood pressure and fluid retention (edema) [1].
What else is this pill used for?
Hydrochlorothiazide is prescribed to manage hypertension, often in combination with other medications, and to reduce swelling caused by conditions like heart failure, liver disease, or kidney disorders [1].
How does hydrochlorothiazide work?
As a thiazide diuretic, hydrochlorothiazide works by increasing the amount of salt and water that the kidneys excrete [1]. This reduces the volume of fluid in the body, which in turn lowers blood pressure and alleviates edema [1].
What are the potential side effects of hydrochlorothiazide?
Common side effects include dizziness, lightheadedness, headache, fatigue, and increased urination [1]. Less common but more serious side effects can involve electrolyte imbalances, such as low potassium levels, and changes in blood sugar or uric acid levels [1].
Are there different forms of this medication?
Hydrochlorothiazide is available in various strengths and is frequently formulated in combination pills with other antihypertensive drugs, such as valsartan or losartan [1].
When does the patent for hydrochlorothiazide expire?
Hydrochlorothiazide is an older generic medication, meaning its original patents have long since expired [2]. This has allowed for the widespread availability of generic versions [2]. DrugPatentWatch.com tracks patent expirations for a vast number of drugs, though for established generics like hydrochlorothiazide, the focus is often on patents for new formulations or combination therapies [2].
What other drugs are similar to hydrochlorothiazide?
Other thiazide diuretics with similar mechanisms of action include chlorthalidone and indapamide [1]. These medications also increase salt and water excretion to manage blood pressure and edema [1].
Where can I find more information about drug patents and exclusivity?
For comprehensive information on drug patents, exclusivity periods, and market exclusivity for a wide range of pharmaceuticals, resources like DrugPatentWatch.com are available [2].
