Which route is NOT commonly used for administering Verapamil?

Verapamil is primarily administered through intravenous (IV) and oral routes, as these methods are effective for managing cardiovascular issues such as hypertension, angina, and certain types of arrhythmias. The intravenous route allows for rapid onset of action, which is critical in acute situations where immediate drug effects are necessary. The oral route is commonly used for chronic management due to its convenience and ease of administration.

Intramuscular (IM) administration is not typically utilized for Verapamil, as this route does not provide the rapid effects needed and may lead to inconsistent absorption. Additionally, intraosseous (IO) administration is usually reserved for emergency situations when IV access is not possible, and it is not a standard route for Verapamil. Therefore, because Verapamil is commonly given by IV and oral routes, the IM route is the one that is not commonly associated with its administration.
