3 Dosage Forms and Routes Free Online FlashCards

What does “dosage form” describe?

A dosage form is the physical preparation containing the active drug ingredient and any inactive ingredients needed to support its delivery and use.

What does “route of administration” describe?

The route of administration is the path by which the medicine enters or contacts the body.

What is characteristic of a drug solution?

A solution has the drug dissolved in liquid, so the preparation is generally uniform.

Why may a suspension need shaking before measuring?

A suspension has drug particles dispersed in liquid; they may settle, so shake it as directed before measuring.

What should be used to measure an oral liquid dose?

Measure oral liquid doses with an appropriate oral syringe or dosing device, not a household spoon.

How are sublingual and buccal medicines administered?

They are placed under the tongue or against the inside of the cheek for absorption through the mouth’s lining; use them as directed rather than swallowing immediately.

How do topical and transdermal routes differ?

Topical medicines are applied to a body surface, usually for local action. Transdermal medicines pass through the skin, often delivering medicine over time.

What does delayed-release mean?

A delayed-release product is designed to release its medicine later rather than immediately.

What does extended-release mean?

An extended-release product is designed to release its medicine over a longer period.

When may a modified-release medicine be crushed or split?

Do not crush, chew, split, or open modified-release products unless product-specific directions permit it; altering the dosage form can affect safety or effectiveness.

What should be followed when reconstituting a medicine?

Use the specified diluent and amount, mix as directed, and follow the product’s storage and discard instructions.

Why is volume alone insufficient for verifying an oral liquid dose?

Concentrations can differ between products, so verify the prescribed dose against the labeled concentration rather than relying on volume alone.
