targets particular receptor for a drug within an organ or tissue

A

receptor targeting

22
Q

these system provides a continuous supply of drug over an extended period of time

A

Prolonged release system

23
Q

it shows the movement of drug molecules from a region of a HIGHER CONCENTRATION TO LOWER CONCENTRATION.

A

Diffusion sustained system

24
Q

In this system, water insoluble polymeric material encases a CORE of drug.

A

Reservoir type

25
Q

These system is most commonly employed in the production of enteric coated dosage forms

A

Dissolution sustained system

26
Q

The drug is coated with A GIVEN THICKNESS COATING which is slowly dissolved in the contents of GI tract.

A

Reservoir

27
Q

generally use resins composed of water-insoluble cross-linked polymers.

A

Ion exchange

28
Q

Developed by Southwest research

A

Multiorifice-centrifugal process

29
Q

is conducted by dispersing core material in a coating solution in which the coating substance is dissolved and in which the core material is insoluble, and then by ATOMIZING THE MIXTURE INTO AN AIRSTREAM.

A

Spray drying

30
Q

this method involve the reaction of MONOMERIC units located at the interface existing between a core material substance and a continuous phase in which the core material is dispersed.

A

Polymerization
