Q. According to the pH-partition theory which form of the drug gets absorbed mostly?

View solution

Q. What helps the ionized drug molecules to pass through the cell membrane passively?

View solution

Q. Acidic drugs are best absorbed through the stomach and basic drugs are best absorbed through the intestine.

View solution

Q. What could be the reason that irrespective of pH any drug gets absorbed mostly from the intestine?

View solution

Q. Drug having a small partition coefficient can rapidly penetrate the lipid membrane but diffusion through the unstirred water layer is a rate-limiting step.

Q. What are the major stability problems which result in poor bioavailability of any orally administered drugs?

View solution

Q. Which form of drug formulation has disintegration time?

View solution

Q. Which tablets have longer Disintegration time?

View solution

Q. Disintegration time is directly proportional to the amount of binder present in the tablet.

View solution

Q. Which of the following is not a limitation granulation?

View solution

Q. The agglomerative phase of the communication method grinds the drug in a ball mill for a long time to affect spontaneous agglomeration. But results showed tablets produced are softer.

View solution

Q. Which of these is not a characteristic of tablet formulation by Agglomerative phase of the communication process?

View solution

Q. What does the graph of Rate of Drug dissolution v/s Compression force with this type of curve interpret?

View solution

Q. Capsules with bigger particles and intense packing have poor drug release and dissolution rate due to an increase in the pore size.
