The topic “Introduction and Different Dosage Forms” is essential for pharmacists as it covers the foundation of how medications are prepared, administered, and absorbed in the body. Different dosage forms ensure that drugs are delivered effectively to the right site of action. These forms include:
- Solid Dosage Forms: Tablets, capsules, powders, and lozenges are common solid forms, preferred for their stability and ease of use.
- Liquid Dosage Forms: Solutions, suspensions, emulsions, and syrups are used for drugs that need quick absorption or for patients who have difficulty swallowing solids.
- Semi-Solid Dosage Forms: Ointments, creams, and gels are applied externally to deliver drugs directly to the skin or mucous membranes.
- Gaseous Dosage Forms: Inhalers and aerosols are used to deliver drugs directly to the lungs, providing rapid action for respiratory conditions.
For the exam, understanding the characteristics, advantages, and disadvantages of each form is crucial. You can test other students by asking questions about the routes of administration, onset of action, and factors influencing drug selection for various conditions.
