For tablets, since our average weight is 623.9 mg, the deviation of individual net weight should not exceed the limits given below: From the results, we can see that the 7 tablets weighed 664.5 mg, 672.2 mg, 658.3 mg, 676.1 mg, 666.2 mg, 666.7 mg and 661.2 mg respectively are having standard deviation of ± 10.0 UNIFORMITY OF WEIGHT OF TABLETS AND CAPSULES. (Ampicillin BP 250 mg) with average weight of 292 mg therefore, we used this rule: Less than 300 mg. ± 10.0. ± 20.0. Question. Give reasons for the non-compliance to test for uniformity of weight. The non-compliance to test for uniformity of weight is due to Based on the result, the tablets used have an average weight of 585.7 mg which is under the category of 'more than 250 mg'. All the 20 tablets that have been carried out did not exceed the limit of + 5.0% and therefore, they are considered to pass the test
For the tablets, the average weight for each tablet is 0.6586g which is much lesser than 80mg. So, the percentage of deviation of individual weight from the average weight should not exceed plus minus 10.0 % for minimum 18 tablets while plus minus 20.0% for maximum 2 tablets Alternatively, products listed in item (W4) above that do not meet the 25 mg/25% threshold limit may be tested for uniformity of dosage units by Weight Variation instead of the Content Uniformity test if the concentration relative standard deviation (RSD) of the drug substance in the final dosage units is not more than 2%, based on process validation data and development data Uniformity of weight of tablets and capsules is an important quality assessment to ensure that each of the tablet and capsule produced meets the requirement of pharmacopoeia standard and also manufacturing standard. Uniformity of weight test is not applicable to tablets and capsules required to comply with the test for uniformity of content The maximum deviation percentage is -5.5538%. This shows that all tablets used is our experiment are uniform from the aspect of weight. The average weight of the capsule Amipicilin is 0.3741g (374.1mg). Therefore, this capsule should has minimum 18 capsules that in the range of ± 7.5% and maximum 2 capsules that in the range of ± 15.0% When the average mass is equal to or below 40 mg, the preparationis not submitted to the test for uniformity of mass but to the test foruniformity of content of single-dose preparations (2.9.6).

From the result obtained, the tablets used has an average weight of 683.9 mg which is under the category of '250mg and more' The uniformity of weight of tablets is acceptable as all 20 tablets do not deviate from ±5%. For capsule, the average mass obtained is 0.2947g that is more than 300mg, thus minimum 18 capsules must not deviate from average mass by ± 7.5% Uniformity of Weight/ Weight variation test Coated tablets are exempted from these requirements but must conform to the test for content uniformity. Uniformity of weight is a function of granulation quality, flow of granulation and machine performance. However, sometimes these ranges are not sufficiently narrow Weight Variation Limits IP/BP Limit USP 80 mg or less 10% 130mg or less More than 80mg or Less than 250mg 7.5% 130mg to 324mg 250mg or more 5% More than 324mg Weigh individually 20 units selected at random or, for singledose preparations in individual containers, the contents of 20 units, and calculate the average weight
Content Uniformity requirements may be applied in all cases. The test for Content Uniformity is required for: 1. coated tablets, other than filmcoated tablets containing 50 mg or more of an active ingredient that comprises 50% or more (by weight) of one tablet; 2. transdermal systems; 3 Tablet friability, weight uniformity, thickness and tablet diameter tests were conducted on the samples using standard method 6 Table III. Chemical identification test and content of active ingredient uniformity test were conducted according to the standard method in British Pharmacopea 2002 7 The effects of tablet coating and capsule shell on the results of the mass variation test were studied. The mass variation of outer crusts (coatings, capsule shells) and inner cores (core tablets, fillings) was measured separately in several products. The effects of coating on weight variability were very large for sugar-coated tablets The uniformity of dosage units can be evaluated either by measuring the content uniformity or the weight of the tested units. The test for weight variation is applicable for hard capsules, uncoated tablets and film-coated tablets. The test for content uniformity is required for all dosage

The tablet which are too thick cannot be degradedand will remain in the body and produce toxic effects. From the result, the mean thickness for all tablets is 5.53 mm. The result that obtained for all the ten tablets have similar value. Hence, all the ten antibiotic tablets have the uniformity of thickness. Third aspect is the hardness The results from the in-process dosage units can also be used for batch release testing (non-weight corrected). If the in-process dosage units are not the finished dosage form (e.g., tablet core vs. film coated tablet), content uniformity data for the in-process and finished dosage forms should be compared to demonstrate similarity
tablet, but the mean average could still show an acceptable weight. For example, if you are making batches of 200 tablets or 200 cap-sules and want to verify the contents of each individual dose but are not sure where to start, then first you need to determine whether the Content Uniformity (CU) or WV method can be used.

Procedure - weigh accurately 20 pills and calculate the average weight, then weigh each of them accurately. Compare the weight of each pill with the labelled or average weight. Not more than two (2) pills should deviate from the limit of weight variation, and none should deviate from twice. Uniformity of content studies are an essential step in the quality control of tablets or capsules as defined in all major pharmacopoeias. It ensures that all tablets are within a tolerance of their average weight giving intra and inter batch uniformity data
. What is Content Uniformity. Content uniformity is a test used to evaluate the equality of the dosage of a pharmaceutical drug. The method is applicable for tablets which contain the active ingredient in less than 10 mg or 10% W/W Thus, the allowance to substitute Weight Variation for Content Uniformity may be seen as offering a benefit to manufacturers. In the case of a two-component tablet, the Uniformity of Dosage Units test requirement will be met by the Weight Variation procedure for the component that is present at 25 mg or more and also comprising 25% of the. TABLETS (1998:0478) TESTS Uniformity of content (2.9.6). Unless otherwise prescribed or justified and authorised, tablets with a content of active ingredient less than 2 mg or less than 2 per cent of the total mass comply with test A for uniformity of content of single-dose preparations. If the preparation has more than one active ingredient.
If film-coated tablets fail this test it may be because of variability in the thickness (mass) of the coatings. In such a case, a test for 5.1 Uniformity of content for single-dose preparations should be applied; if the tablets meet the requirement of this test, they can be considered acceptable.. Capsule Uniformity of the diameter of tablet follows the pharmacopoeial standard. All of the percentage average deviation value must not exceed ± 5% for tablets with diameter less than 12.5 and ± 3% for diameter of 12.5 mm or more. All of this test could be done by using tablet testing instrument called PHARMATEST PTB 311 This test is applicable for uncoated and film coated tablets. For this test according to BP weigh individually 20 tablets taken at random and determine the average mass. As per BP the tablet complies with the test if not more than 2 of the individual masses deviate from the average mass by more than the percentage deviation as shown in Table
.5% 250mg or more 5 Uncoated tablets and film-coated tablets formulated to contain 5% or more of the active ingredient should comply with the uniformity test of weight of tablet. In this experiment, the average weight of 20 tablets selected at random was 664.5mg which was greater than 250mg

2. Exercise regularly. Regular physical activity — such as 150 minutes a week, or about 30 minutes most days of the week — can lower your blood pressure by about 5 to 8 mm Hg if you have high blood pressure. It's important to be consistent because if you stop exercising, your blood pressure can rise again The experiment is conducted to test the uniformity of the tablets in the aspects of thickness, diameter and hardness. Based on our result, the average thickness of tablets is 4.057mm, as the thickness obtained for each 10 tablets lies within the range of 4.00mm to 4.20mm. The result shows small value of difference which indicate the tablets are. USP method 905 Uniformity of Dosage Units describes how to calculate the weight variation for your dosage forms. If you need a copy of method simply drop me an email at email@example.com Regard . Tablets with single or multiple score lines allow the administration of a proportion of the tablet. In general, pharmacopoeial mass or weight uniformity compliance criteria do not consider the specific broken-tablet situation, and consequently the general unit-dose criteria are generally believed to be applicable to half-tablets and quarter-tablets as well The distribution of weight is known to be normal; We assume \sigma = 0.5σ=0.5 is known n=30 sample mean weight = 18.5 ounces.

If you suffer from high blood pressure, that extra water, which translates to a higher blood volume, keeps your blood pressure high. Diuretics work, to put it simply, by preventing the kidneys from reabsorbing sodium, in turn allowing it to leave your body — by way of urination, and of course together with excess fluid High blood pressure can lead to many serious health problems, such as heart attack, heart failure, stroke, and kidney disease. Treating high blood pressure early is important in preventing these. Content uniformity testing is an important assessment for oral solid dosage (OSD) forms. It is one of two allowable tests to assess the uniformity of dosage units (UDU), the other being weight variance, says Darren Andrews, Pharma Business Manager, Raman Spectroscopy, Cobalt Light Systems, part of Agilent Technologies Aspirin tablets are available in white polypropylene containers with polyethylene tamper-evident child-resistant caps of 28, 50 or 1000 tablets. Aspirin tablets are also available in child-resistant blister packs, each containing 28 tablets. Not all pack sizes may be marketed
Weight variation test: The result showed that weight variation was ranging from 797mg to 799mg. Hence the tablets complied within the IP limit in terms of uniformity of weight (Table 3). Friability: In friability test the maximum weight loss should be not more than 1%.The results revealed that the tablets passed the friability test (Table 3) The types of tablet that must be tested for uniformity of diameter include uncoated and coated tablets with the exception of enteric tablets, film-coated tablets and sugar-coated tablets. As for the uniformity of content, it is applicable for uncoated tablets, coated tablets, effervescent tablets, hard capsules, soft capsules, enteric-coated. The weight and content uniformity of tablet quarters (data were normally distributed) were compared by one-way analysis of variance using the Minitab V.17.1.0 statistical software package (Minitab, USA). A P value of less than 0.05 was considered significant Children—Dose is based on body weight and must be determined by your doctor. For oral dosage form (tablets): Adults—80 to 320 milligrams (mg) per day, given in divided doses. Children—Use and dose must be determined by your doctor. For high blood pressure (hypertension): For oral dosage form (extended-release capsules) Withdrawing blood pressure medications is safe, provided people lost weight and blood pressure was checked regularly, in case tablets needed to be reintroduced. More information Almost 1 in 2 U.S. adults—or about 108 million people—have high blood pressure. 1. More than 1 in 7 U.S. adults—or about 37 million people—may have chronic kidney disease (CKD). 2.
