1. Dosage Forms
Dosage forms are the physical forms in which drugs are produced and
administered to patients. Proper design of dosage forms ensures
accurate dosing, stability, and patient acceptability.
2. Classification of Dosage Forms
- Solid dosage forms (tablets, capsules, powders)
- Liquid dosage forms (solutions, syrups, suspensions)
- Semi-solid dosage forms (ointments, creams, gels)
- Parenteral dosage forms (injections)
3. Advantages of Proper Dosage Form Design
- Improved patient compliance
- Accurate and uniform dosing
- Protection of drugs from degradation
- Controlled drug release
4. Factors Affecting Choice of Dosage Forms
Factors include physicochemical properties of the drug, route of
administration, patient age, disease condition, and stability of
the formulation.
5. Seection of Appropriate Dosage Form
Selection of a suitable dosage form depends on therapeutic objectives,
drug characteristics, convenience of administration, and safety.
