Answer: Drug formulations include tablets, capsules, syrups, injections, and topical applications.

Question: Explain the concept of a prodrug.
Answer: A prodrug is an inactive compound that is metabolized in the body to release the active drug.

Question: What are the types of chemical bonds in drug molecules?
Answer: Drug molecules contain covalent, ionic, hydrogen, and van der Waals bonds, which determine their stability and interactions.

Question: Describe the process of drug synthesis.
Answer: Drug synthesis involves chemical reactions to create active pharmaceutical ingredients from raw materials.

Question: What is a buffer solution, and why is it important in drug formulation?
Answer: A buffer solution maintains a stable pH, ensuring the stability and effectiveness of the drug.
