Disintegration test for Gastro-resistant capsules/ Delayed release capsules

Title: Standard operating procedure of Disintegration test for Gastro-resistant capsules/ Delayed release capsules.

1.0 OBJECTIVE:

To lay down a procedure of Disintegration test for Gastro-resistant capsules/ Delayed release capsules.

2.0 SCOPE:

This SOP shall be applicable to Q.C Dept.

3.0 RESPONSIBILITY:

3.1 Doing: Q.C Analyst.

3.2 Checking: Q.C-Manager.

4.0 ACCOUNTABILITY:

4.1 Head of the Q.C Department.

5.0 MATERIAL AND EQUIPMENT:

5.1 Disintegration Apparatus.

5.2 Glassware (according to requirement).

5.3 18 dosage units.

5.4 Immersion fluid 1 (0.1M Hydrochloric acid).

5.5 Immersion fluid 2 (phosphate buffer solution pH 6.8).

6.0 PROCEDURE:

6.1 Assemble the Disintegration Apparatus.

6.2 Switch ON the main supply of Disintegration Apparatus.

6.3 Operate the Disintegration Apparatus according to the SOP.

6.4 Take 6 dosage-units.

6.5 Place 1 dosage unit in each of the 6 tubes of the basket along with the perforated plastic discs, if prescribed.

6.6 Take 900ml of simulated gastric fluid (0.1M HCl) in beaker.

6.7 Use simulated gastric fluid, maintained at 37±2^oC and frequency rate between 29-32 cycles/min.

6.8 Place 1 dosage unit in each of the 6 tubes of the basket in beaker.

6.9 Set the basket in motion for 2 hour, without the disc.

6.10 After 2 hour of operation in simulated gastric fluid, lift the basket from the fluid and observe the capsules: the capsules show no evidence of disintegration, cracking or softening.

6.11 Remove the gastric fluid for the beaker and wash it properly.

6.12 Add simulated intestinal fluid (phosphate buffer solution pH 6.8) in beaker up to 900ml. Add a disc to each tube.

6.13 Operate the apparatus, using simulated intestinal fluid, maintained at 37±2^oC and frequency rate between 29-32 cycles/min for the time specified in the monograph (or when the capsules are completely disintegrate; approx. 60min).

6.14 Lift the basket from the fluid, and observe the capsules: all the capsules disintegrate completely.

6.15 If 1 or 2 capsules fail to disintegrate completely, repeat the test on additional 12 capsules.

6.16 After that it must meet the specifications of B.P, if not then batch will be fail.

6.17 Limit:

6.17.1 All of the dosage units must disintegrate completely. If 1 or 2 dosage units fail to disintegrate, repeat the test on 12 additional dosage units.

6.17.2 The requirement of the test met if not less than 16 of the 18 dosage units tested have disintegrated.
