The USP limit for weight variation of powder vials is typically ±10% of the average weight of the powder in the vial. This means that individual vials should weigh within 10% above or below the average weight as specified by the United States Pharmacopeia (USP) standards.
The United States Pharmacopeia (USP) specifies a weight variation limit of ±5% for tablets with a weight of 300 mg or less and ±3% for tablets weighing more than 300 mg. This means that individual tablets should not deviate more than these percentages from the average weight of the tablets in a batch.
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 waqassial@hotmail.com Regards

The United States Pharmacopeia (USP) specifies that the dissolution test for tablets typically requires that at least 80% of the labeled amount of the active pharmaceutical ingredient be released within a specified time frame, often 30 minutes, depending on the formulation. This limit ensures that the tablet dissolves adequately to provide the intended therapeutic effect. Specific products may have different dissolution criteria, so it's essential to refer to the individual monograph for precise requirements.
To test Chloride limit according to USP monograph, you would typically use a silver nitrate solution and potassium chromate as indicator. For Sulfate limit test, turbidimetric method with barium chloride solution is commonly employed. Both tests involve titration techniques to determine the presence and concentration of Chloride and Sulfate ions within the specified limits as per the USP guidelines.
The USP (United States Pharmacopeia) specifies that the hardness of tablets should typically be within the range of 4 to 8 kg for most oral tablets, although this can vary depending on the specific formulation and intended use. Hardness is measured using a hardness tester and is critical for ensuring that tablets can withstand handling, shipping, and storage without breaking or crumbling. Proper hardness contributes to the tablet's dissolution and bioavailability, impacting its effectiveness. Always refer to the specific monograph for each drug for precise requirements.
The USP (United States Pharmacopeia) specifies that the relative standard deviation (%RSD) for an assay should generally be less than 2%. However, this limit may vary depending on the specific requirements of the assay and the drug being tested.

BP - British Pharmacopoeia and USP - United States Pharmacopeia.In the world there are various pharmacopeias which are guidelines for the Pharmaceutical Industry for manufacture and testing of drugs. BP and USP are two of approximately 30 country or region run pharmacopeias. In the BP and USP there are specific tests which must be followed to be labeled BP or USP and depend on which drug (aspirin, acetominophen, etc) is being tested. In the US, it is a legal requirement that all drugs meet or exceed the USP. In various other places the laws may not be as strict to where any pharmacopeia may be used (British, Canadian, Japanese, US, European etc).
What are the advantage of the USP?
