CLOPIDOGREL 75 mg + ASPIRIN 75 mg Tablet Finish Product Testing Procedure

Description:
A White powder.
Procedure:   Take 2.0 g of the test sample in a watch glass and observe visually with black background. Check the appearance of color, nature and any visible foreign particles.

Identification: (By HPLC)

The retention time of major peak of the sample preparation corresponds to that of the standard preparation as obtained in the assay.

Loss on Drying: (By Moisture Analyzer)

Procedure: 
Turn on instrument 20 minute before the test. Take 2 g powder spread uniformly on Moisture Analyzer plate. Close the lid and press start button.
NMT 5.0% when determined by LOD Apparatus, Use 2.0 g of powder.
Assay: (Limit: 90%-110%).

Assay Procedure:

Mobile Phase:
Methanol and Distilled Water (800:200)
Diluent: Mobile phase
Standard Stock solution: Take 75 mg aspirin WS and 97.8mg of clopidogrel hydrogen sulfate WS equivalent to 75 mg of clopidogrel into a 100 volumetric flask. Add diluent, and shake for up to 2 minute to disperse. Following dispersion, sonicate for 3 min, and shake for 2 min. Dilute with diluent to volume.
Standard solution: Take 2 mL from the standard stock solution in 100mL volumetric flask and make up volume with diluents. Pass through a membrane filter of 0.45-µm pore size.
Sample stock solution: Weigh and finely powder 10 g of granules. Transfer a portion of the powder, equivalent to75 mg of aspirin and 75 mg of clopidogrel into a 100 volumetric flask. Add diluent, and shake for up to 2minute to disperse. Following dispersion, sonicate for 3 min, and shakefor2 min. Dilute with diluents to volume. Filter the solution.
Sample solution: Take 2 mL from the filtrate in 100mL volumetric flask and make up volume with diluents. Pass through a membrane filter of 0.45-µm pore size.

Hardness Test & Dimensions:

Perform the hardness test on 10 tablets and take the average. Power on the instrument and regulate zero adjustment and preset the ‘’HARDNESS’’ and “Thickness” mode. Place the tablet on the test plate, begin testing and read the hardness thickness and diameter. Clean the shattered tablet and print out test results, perform the test on 10 tablets and take the average.
Hardness Standard Limit: 7 Kg – 20 Kg

Friability Test:

For tablets with a unit mass equal to or less than 650 mg, take a sample of whole tablets corresponding to 6.5 g. For tablets with a unit mass of more than 650 mg, take a sample of 10 whole tablets. The tablets should be carefully dedusted prior to testing. Accurately weigh the tablet sample, and place the tablets in the drum. Rotate the drum 100 times, and remove the tablets. Remove any loose dust from the tablets as before, and accurately weigh. Generally, the test is run once. If obviously cracked, cleaved, or broken tablets are present in the tablet sample after tumbling, the sample fails the test. If the results are doubtful or if the weight loss is greater than the targeted value, the test should be repeated twice and the mean of the three tests determined. A maximum mean weight loss from the three samples of not more than 1.0% is considered acceptable for most products.
% FRIABILITY=    W1-W2   x 100/W1

Disintegration Test:

Place the beaker filled with water into the beaker stand inside the bath and. Switch on the instrument, set the temperature at 37ºC± 2º C and wait till the temperature of the beaker reaches to the 37ºC± 2º C.
