Which of the following best describes the administration form of enteric-coated aspirin?

The administration form of enteric-coated aspirin is best described as digestive-resistant. Enteric coating is specifically designed to protect the aspirin from being dissolved in the acidic environment of the stomach. Instead, the coating allows the aspirin to pass through the stomach intact and dissolve in the more alkaline conditions of the small intestine. This feature is particularly beneficial as it helps to reduce gastric irritation and improves the drug's absorption profile.

This form is distinct from immediate release, which would dissolve rapidly in the stomach, and extended release, which is designed to release the active ingredient over a longer duration in a controlled manner. Injection, on the other hand, refers to a completely different method of drug delivery that bypasses the digestive system altogether. Therefore, the best description of enteric-coated aspirin is that it is designed to resist digestion until it reaches the appropriate part of the gastrointestinal tract.
