1 Paste
2 Troche
3 Powder
4 Liniment
5 Suppository

Answer 1

Medication forms that can be used for topical administration are paste, powder, and liniment. Troches and suppositories are not typically used for topical application.

Step-by-step explanation:

Medications that can be administered via the topical route are generally intended for local effect on the skin or mucous membranes. The following medication forms from the given options can be administered topically:

• Paste - a semi-solid preparation that often contains a higher concentration of solids and is designed for topical application.
• Powder - often used in the treatment of skin irritations and fungal infections, powders can be applied topically.
• Liniment - a liquid or semi-liquid preparation that is applied to the skin to produce a soothing effect, often containing medications that relieve pain and stiffness.

Troches are meant for oral administration, slowly dissolving in the mouth, and suppositories are typically administered rectally or vaginally, not topically.
