Question 13

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

Troches are designed to dissolve in the oral cavity, allowing for the medication to be absorbed through the mucous membranes. This method of administration is beneficial for patients who may have difficulty swallowing traditional tablets.

A) Sustained release

Sustained-release tablets are formulated to release their active ingredients slowly over time after being swallowed. They are not intended to dissolve in the mouth but rather in the gastrointestinal tract, making them unsuitable for this question.

B) Troche

Troches are specifically designed to dissolve in the mouth, providing a convenient method for delivering medication directly into the system through the oral mucosa. This characteristic makes them the correct answer to the question regarding tablets that dissolve in the mouth.

C) Effervescent

Effervescent tablets are designed to dissolve in water before ingestion, producing a fizzy solution. While they may dissolve quickly, they do not dissolve in the mouth directly, thus making them incorrect in this context.

D) Enteric coated

Enteric-coated tablets are designed to resist dissolution in the acidic environment of the stomach and only dissolve in the more alkaline environment of the intestines. As such, they are not applicable to the question about tablets that dissolve in the mouth.

Conclusion

Troches are uniquely formulated to dissolve in the mouth, facilitating rapid absorption of medication. In contrast, sustained-release, effervescent, and enteric-coated tablets serve different purposes and do not meet the criteria outlined in the question, confirming that B is indeed the only correct choice.
