1. Why are powdered medicaments mixed during tablet preparation?

Powdered medicaments are mixed primarily to reduce interparticle attraction, improving uniformity and flow properties.

2. How many centimeters is one nanometer (nm)?

One nanometer (nm) is equal to 10⁻⁷ cm.

3. Which cholinergic receptor is present on intestinal muscles?

The muscarinic receptor is present on intestinal smooth muscles and mediates contraction.

4. What is the correct order of increasing eluent power for benzene, ether, chloroform, and ethyl acetate?

The correct order is Benzene < Ether < Chloroform < Ethyl acetate.

5. What is the Limulus test used for?

The Limulus Amebocyte Lysate (LAL) test is used to detect pyrogens (bacterial endotoxins) in parenteral preparations.

6. What is an essential requirement of the mobile phase in HPLC?

The mobile phase in HPLC must have a constant flow rate without pulses to ensure accurate and reproducible results.

7. When was the Drug Development Authority (DDA) established?

DDA was established in 2036 B.S.

8. What effect does 3-etherification of morphine molecules have?

3-etherification increases both analgesic effect and addiction potential.

9. What happens when an electrolyte is added to a lysol?

The addition of an electrolyte causes coagulation by reducing the repulsion between particles.

10. What does hydrolysis of Salicin yield?

Salicin hydrolyzes to salicylic alcohol + glucose.

11. How is Lignocaine Hydrochloride officially assayed?

It is assayed using non-aqueous titration.

12. Which drug is dangerous when supplemented with Digoxin in supraventricular arrhythmia?

Quinidine can increase Digoxin toxicity by reducing its clearance.

13. What is the pH range for insulin injection I.P.?

The pH should be maintained between 3 and 3.5.

14. What is Wagner’s test used for?

Wagner’s test is used to detect alkaloids.

15. What does "half-life" mean in radioactive pharmaceuticals?

It refers to the time taken for the activity to decay to one-half of its initial value.
