Question 1

Which of the following is a false statement for vapour pressure pump?

Accepted Answer

The false statement is that the drug solution chamber is separated by rigid walls. In a vapor pressure pump, the separation is typically flexible, allowing the vapor pressure to exert force on the drug solution, pushing it out of the device. Rigid walls would not allow for this necessary interaction between the chambers.

Question 2

After implantation of a vapour pressure pump, the body has to get heated by exercising so that the
volatile liquid vaporizes.

Accepted Answer

Vapor pressure pumps used in medical applications, such as drug delivery systems, operate based on the vapor pressure of a volatile liquid inside the pump. They do not require the body to be heated by exercising for the liquid to vaporize; instead, they rely on the inherent vapor pressure of the liquid to function at body temperature.

Question 3

Which of the following is a characteristic of battery powered pumps?

Accepted Answer

Battery-powered pumps can be programmed to release drugs at a controlled rate, allowing for precise dosing and timing of medication delivery. This is a key characteristic that distinguishes them from other types of drug delivery systems.

Question 4

The drug loading in resealed erythrocytes can be done by 1st immersing the cells in a buffered
hypertonic solution.

Accepted Answer

The drug loading in resealed erythrocytes is typically done by first immersing the cells in a hypotonic solution, not a hypertonic one, to allow the cells to swell and open pores for drug entry.

Question 5

How are MLV liposomes made?

Accepted Answer

MLV (Multilamellar Vesicles) liposomes are made up of a series of concentric bilayers of lipid, resembling an onion structure. This allows for the encapsulation of a larger volume of aqueous solution than single bilayer vesicles.
