Dosage Forms by Release CharacteristicsDosage forms can also be classified based on their release characteristics:1. Immediate-Release Dosage Forms: Release the drug rapidly, resulting in a quick onset of action.2. Extended-Release (ER) or Controlled-Release (CR) Dosage Forms: Release the drug gradually over time, reducing the dosing frequency.3. Delayed-Release Dosage Forms: Prevent drug release until they reach a specific part of the gastrointestinal tract, often achieved through enteric coatings.4. Osmotic Release Dosage Forms: Controlled-release forms that use osmotic pressure to deliver the drug.5. Sustained-Release Dosage Forms: Ensure a continuous and controlled drug release over an extended period.6. Enteric-Coated Dosage Forms: Feature a protective coating that resists dissolution in the stomach, releasing the drug in the intestines.7. Bi-layered Dosage Forms: Combine immediate-release and sustained-release layers for dual drug release.8. Buccal and Sublingual Dosage Forms: Administered through the buccal or sublingual mucosa for rapid absorption.Dosage forms are chosen based on drug characteristics, patient needs, and the intended therapeutic effect, ensuring that medications are administered safely and effectively.
