Study Notes
Main Focus of Pharmaceutics
- Pharmaceutics is primarily concerned with the formulation of medications into suitable dosages for effective delivery and action.
- It involves the design and development of pharmaceutical products, ensuring the stability, efficacy, and safety of drugs.
Role of Additives or Excipients in Medicines
- Additives or excipients are substances other than the active pharmaceutical ingredient (API) used in drug formulations.
- They enhance drug stability, bioavailability, and absorption while facilitating manufacturing processes.
- Excipients can aid in taste masking, provide bulk, and ensure proper consistency in dosage forms.
Dosage Forms
- Dosage forms refer to the physical forms in which medication is produced and administered.
- They include a variety of pharmaceutical formats, such as tablets, capsules, liquids, ointments, and injections tailored to specific routes of administration.
Liquid Dosage Forms (LDFs)
- LDFs are preparations that contain one or more active ingredients dissolved or suspended in a liquid medium.
- They are often preferred for their ease of ingestion, rapid absorption, and precise dosing.
Types of Liquid Dosage Forms
- Solutions: Homogeneous mixtures of solute and solvent where the drug is fully dissolved.
- Suspensions: Particulate drugs dispersed in a liquid vehicle, requiring shaking before use.
- Emulsions: Mixtures of two immiscible liquids, often oil and water, stabilized by emulsifying agents.
- Syrups: Concentrated solutions of sugar or sugar substitutes, often flavored and used for sweetening medications.
- Elixirs: Clear, sweetened hydro-alcoholic solutions used for liquid medications, providing better solubility for certain drugs.
