Question 60

Troche is the type of tablet that is dissolved in the mouth.

Troches are specifically designed to dissolve in the mouth, allowing for the medication to be absorbed directly through the mucous membranes. This method of administration can provide quick relief for certain conditions.

A) Sustained release

Sustained release tablets are formulated to release their active ingredients slowly over time, which means they are designed to be swallowed whole rather than dissolved in the mouth. This type of tablet is not intended for immediate absorption in the oral cavity.

B) Troche

Troches are indeed designed to dissolve in the mouth, providing a convenient method for medication administration. They are often used for local effects in the throat or mouth, making them the correct choice for this question.

C) Effervescent

Effervescent tablets are designed to dissolve in water, producing a fizzy solution that is then consumed. While they do dissolve, they are not intended to dissolve directly in the mouth, making them incorrect in this context.

D) Enteric coated

Enteric coated tablets are designed to resist dissolution in the acidic environment of the stomach, allowing them to dissolve only in the more neutral pH of the intestines. They are meant to be swallowed whole and are not suitable for dissolution in the mouth.

Conclusion

Troches are the only option among the choices provided that is specifically formulated to dissolve in the mouth for direct absorption. The other options—sustained release, effervescent, and enteric coated—serve different purposes and do not fit the criteria of being dissolved orally. Thus, the selection of troche as the correct answer is justified based on its unique characteristics and intended use.
