Which administration route is considered the least expensive and most convenient for patients?

The oral administration route is considered the least expensive and most convenient for patients for several reasons. First and foremost, oral medications can be taken easily by most individuals without the need for special skills or equipment, making it accessible for a wide range of patients. This convenience often leads to better adherence to medication regimens, as patients can take their medications with water during meals or as part of their daily routines.

Cost is another significant factor; oral medications generally are less expensive to produce and distribute than those requiring injections or specialty delivery systems. Additionally, oral medications do not necessitate the use of sterile equipment, making them more affordable and practical for both healthcare providers and patients.

In contrast, administration routes such as intramuscular and subcutaneous require injections, which can be more invasive, potentially causing discomfort and requiring additional training or assistance. Transdermal methods, while convenient in some respects, often involve higher costs associated with the formulation and application of patches.

Therefore, when considering factors of convenience and expense, oral administration stands out as the most favorable option for patient use.
