How is Metformin primarily excreted from the body?

• A. Bile
• B. Renal
• C. Feces
• D. Respiratory system

Answer: (B)

Metformin is primarily excreted through the renal system, meaning it is eliminated from the body via the kidneys. The kidneys filter the drug from the bloodstream, and it is then excreted unchanged in the urine. This is important for understanding both the pharmacokinetics of Metformin and its potential side effects, especially in patients with renal impairment. Since Metformin is not metabolized extensively in the liver, the renal route of excretion plays a critical role in maintaining appropriate drug levels in the body and avoiding toxicity. In contrast, the other routes of excretion do not play a significant role for Metformin. For instance, while some drugs may be eliminated through bile or feces, Metformin's renal excretion is the primary pathway. Additionally, its excretion via the respiratory system is negligible and not relevant for its pharmacological action or elimination. Understanding these details is crucial for optimizing treatment and ensuring the medication’s safety in patients, especially those with compromised kidney function.
