Long acting (detemir, glargine) peak is typically:

• A. 4-9 hrs
• B. 2-4 hrs
• C. 8-12 hrs
• D. 12-24 hrs

Answer: (A)

Long-acting insulins are designed to provide a steady basal level with no pronounced peak. In practice, detemir can show a small, modest peak somewhere in the middle of the dosing interval, while glargine is often considered peakless. The best way to reflect this in a single range is roughly 4–9 hours after injection, which captures the mid-interval peak that can occur with these insulins. The other ranges either describe the time frame of rapid- or short-acting insulins (too early) or describe overall duration rather than a true peak (too late).
