Final answer:
Diazepam is a benzodiazepine that is reliably absorbed when given IM. Other benzos like lorazepam and midazolam can also be administered via IM injection, but their absorption may be less reliable.
Step-by-step explanation:
Intramuscular (IM) absorption refers to the rate and extent at which a drug is absorbed into the bloodstream after it has been injected into a muscle.
When it comes to benzodiazepines (benzos), diazepam is a commonly used example that is reliably absorbed when administered intramuscularly. Diazepam is often used in emergency situations to provide rapid sedation and seizure control.
Other benzos like lorazepam and midazolam can also be given via IM injection, but their absorption may be less reliable than diazepam.
