Which route of administration is safest, most economical & most common?

  1. Transdermal

  2. Intravenous

  3. Oral

  4. Inhalation

The correct answer is: Oral

Oral administration is the most common route of administration because it is easy, convenient, and relatively safe since it involves taking medication through the mouth. Transdermal administration requires the use of a patch or gel, which may cause skin irritation or allergic reactions. Intravenous administration involves injecting medication directly into the bloodstream, which can be risky and expensive. Inhalation refers to breathing in medication, which may not be suitable for individuals with respiratory problems and may cause irritation. Therefore, oral administration is the best option for its safety, cost-effectiveness, and convenience.
