Question

Match List I with List II:

List I Dissolution apparatus		List II Name
A.	Type I	I.	Reciprocating holder
B.	Type 5	II.	Paddled overdisk
C.	USP App 6	III.	Basket type
D.	USP App 7	IV.	Cylinder apparatus

Choose the correct answer from the options given below

• A. A-III, B-II, C-IV, D-I
• B. A-IV, B-I, C-II, D-III
• C. A-II, B-III, C-I, D-IV
• D. A-I, B-II, C-III, D-IV

Answer 1

The Correct Option is A

To solve this question, we need to match the dissolution apparatus types listed in 'List I' with their corresponding names in 'List II'. Let's evaluate each pair one by one:

1. Type I: This is known as the Basket Type. It involves a cylindrical basket that holds the tablet and rotates at a fixed speed in the dissolution medium. Therefore, Type I corresponds to option III in List II.
2. Type 5: This is known as the Paddled Over Disk. It is used for testing transdermal delivery systems, where the sample is placed over a disk and stirred with a paddle. Hence, Type 5 matches with option II in List II.
3. USP App 6: This is known as the Cylinder Apparatus. It utilizes a rotating cylinder to hold the sample in a vertical position during dissolution. Thus, USP App 6 corresponds to option IV in List II.
4. USP App 7: This is known as the Reciprocating Holder. It is particularly useful for extended-release dosage forms and works by reciprocating the sample in a vertical movement. Therefore, USP App 7 aligns with option I in List II.

Now, let's compile our matched list based on the analysis:

• A - III: Type I is the Basket type.
• B - II: Type 5 is the Paddled over disk.
• C - IV: USP App 6 is the Cylinder apparatus.
• D - I: USP App 7 is the Reciprocating holder.

Therefore, the correct answer matches the sequence mentioned in the option: A-III, B-II, C-IV, D-I.
