Table sugar can be used for treatment of hypoglycaemia secondary to all of the following drugs EXCEPT:
## Core Concept
The question tests the understanding of managing hypoglycemia caused by various medications and the role of table sugar (sucrose) in its treatment. Hypoglycemia is a condition characterized by abnormally low blood glucose levels. It can be induced by several types of medications, including those used for diabetes management.
## Why the Correct Answer is Right
The correct answer, , refers to medications like **Warfarin**, which is an anticoagulant used to prevent and treat thrombosis and embolism. Warfarin does not cause hypoglycemia as a side effect; instead, it works by inhibiting the synthesis of vitamin K-dependent clotting factors. Therefore, table sugar would not be used to treat hypoglycemia caused by Warfarin because Warfarin does not cause hypoglycemia.
## Why Each Wrong Option is Incorrect
- **Option A:** . Medications like **Insulin** and **Insulin secretagogues** (e.g., sulfonylureas, meglitinides) can cause hypoglycemia. Table sugar can be used to treat hypoglycemia caused by these drugs as a quick source of glucose.
- **Option B:** . Certain **Beta-blockers** can mask symptoms of hypoglycemia but do not typically cause it. However, in the context of this question, if a beta-blocker contributes to hypoglycemia (rarely, by affecting glucose metabolism), glucose administration would still be appropriate.
- **Option C:** . **Ethanol** (alcohol) can cause hypoglycemia, especially in fasting individuals, by inhibiting gluconeogenesis. Administering glucose, including table sugar, can help treat alcohol-induced hypoglycemia.
## Clinical Pearl / High-Yield Fact
A key point to remember is that not all types of hypoglycemia should be treated with glucose. For example, **alcohol-induced hypoglycemia** might require **thiamine** administration before glucose to prevent Wernicke's encephalopathy. However, for immediate treatment of hypoglycemia due to diabetes medications or other causes, a quick source of glucose like table sugar can be lifesaving.
