Sodium tolbutamide is a medication that falls under the category of sulfonylureas, a class of drugs used to treat type 2 diabetes mellitus (formerly called non-insulin-dependent diabetes) [1, 2]. Here's a breakdown of key points about sodium tolbutamide:
Function:
- It helps lower blood sugar levels by stimulating the pancreas to release more insulin [1]. Insulin is a hormone that helps the body absorb glucose (sugar) from the bloodstream into cells for energy.
Use in Diabetes Treatment:
- Sodium tolbutamide was once a more common medication for type 2 diabetes, but it has largely been replaced by newer sulfonylureas due to several factors [2, 3].
Reasons for Less Frequent Use:
- Shorter duration of action: Compared to newer drugs, sodium tolbutamide has a shorter duration of action, meaning its blood sugar-lowering effects wear off faster [2]. This can increase the risk of blood sugar fluctuations.
- Higher risk of side effects: Sodium tolbutamide can cause more side effects compared to some newer sulfonylureas, such as hypoglycemia (low blood sugar) and jaundice (yellowing of the skin and eyes) [2, 3].
Current Use:
- While less common, sodium tolbutamide may still be prescribed in some cases, such as for patients who cannot tolerate other medications or who have difficulty affording newer options [3].
