What is a common route of administration for antivirals?

Oral administration is a common route for administering antiviral agents due to its ease of use, convenience, and patient preference. Many antiviral medications are formulated to be taken orally, which allows for straightforward dosing and self-administration. This route is particularly favorable in outpatient settings where individuals can take their medication at home without the need for medical supervision.

Additionally, the absorption of oral antivirals into the bloodstream can be efficient, leading to effective therapeutic levels of the drug. This method makes it suitable for long-term treatment of chronic viral infections such as HIV or hepatitis, as well as for shorter courses of treatment for acute infections, such as influenza.

Intramuscular and subcutaneous routes may be used for certain antiviral agents, particularly those requiring depot formulations or when rapid onset of action is necessary. However, these methods often require healthcare professional administration. Transdermal routes may also be considered in some specialized cases but are not commonly used for most antiviral therapies due to issues with drug absorption and formulation challenges. Thus, oral administration remains the most prevalent route for these medications.
