Procedure:

Standard Solution:

Take 40 mg of Rabeprazole sodium equivalent 40 mg of Rabeprazole sodium WS dissolved in 0.1 N sodium hydroxide and make up the volume to 100mL with 0.1 N sodium hydroxide. Shake, and sonicate for 5 minutes to facilitate dissolution

Take 2 mL from standard stock solution and make up the volume to 100 mL with 0.1 N sodium hydroxide.

Sample solution:

Take compression weight of finally grinded granules and dissolved in 0.1 N sodium hydroxide and make up the volume to 100mL with 0.1 N sodium hydroxide. Shake by mechanical mean for 10 minutes to disperse and allow any insoluble matter to settle.

Pass a portion of the sample stock solution through a suitable filter of 0.45um pore size.

Transfer the 2 mL of filtrate to a 50 mL volumetric flask make up volume with 0.1 N sodium hydroxide. Take reading at UV spectrophotometer at 293 nm using 0.1 N sodium hydroxide as blank.

Uniformity of Dosage Units: (By Weight Variation)

Weigh 20 tablets individually and calculate the average weight as:
Average weight = (Weight Of 20 Tablets)/20

Weigh all these tablets individually and mark among these weights maximum (WMax) & minimum (WMin) weight tablets. Calculate the maximum and minimum variation in percent as:

Maximum% age variation =((WMax) – (WAvg.))/WAvg×100

Minimum % age variation ((WMin) – (WAvg.))/WAvg×100

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.

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/W1 x 100

Leak Test:

Take 06 blisters of tablet 03 filled and 03 empty. Dip these blisters in the bowl of leak test apparatus containing colored water. Create vacuum 250 mmHg and hold for one minute. Release vacuum and check the penetration of water inside the blisters. All blisters should be free of water.
