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.

What is the definition of Dissolution per USP?
According to the USP (United States Pharmacopeia), dissolution is defined as the process by which a solid substance enters into a solvent to yield a solution. It is a critical test for assessing the rate and extent of drug release from a solid dosage form.
What is the dissolution test procedure for Nitazoxanide Tablets?
The dissolution test procedure for Nitazoxanide tablets typically involves using a USP dissolution apparatus, often type II (paddle method). The tablets are placed in a specified volume of dissolution medium, commonly 0.1 N hydrochloric acid or phosphate buffer, maintained at a controlled temperature, usually 37°C. The paddle rotates at a defined speed, and samples of the medium are taken at predetermined time intervals to measure the concentration of Nitazoxanide using appropriate analytical techniques, such as UV spectrophotometry. The results are then compared to the acceptance criteria to determine the tablet's dissolution profile.
What is a hardness required for tablet according to usp?
According to the USP (United States Pharmacopeia), the hardness requirement for tablets is typically specified as a minimum force required to crush the tablet. This is often expressed in terms of kiloponds or newtons. The specific hardness requirement may vary depending on the formulation and purpose of the tablet.
What is percent RSD limit for assay as per USP?
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.
What is the usp limits of hardness of tablets?
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.

How to tested Chloride and Sulfate limit test By USP monograph?
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.

Types of dissolution appratus used for drug dissolution?
The two common types of dissolution apparatus used for drug dissolution testing are the USP apparatus I (basket) and USP apparatus II (paddle). The basket apparatus is recommended for capsules and floating dosage forms, while the paddle apparatus is typically used for tablets and other solid dosage forms. Both apparatus are designed to simulate the conditions of the gastrointestinal tract to assess drug release characteristics.
What is the USP limit for weight variation of powder vials?
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.
What is percent RSD limit for assay as per USP?
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.

5 What are the other test done for capsule that are official in the USP?
In addition to disintegration and dissolution tests, the United States Pharmacopeia (USP) outlines several other official tests for capsules. These include tests for content uniformity, which ensures that each capsule contains the specified amount of active ingredient, and moisture content determination, which assesses the water content that may affect stability. Additionally, the USP may require testing for microbial limits to ensure safety and purity. Lastly, capsule appearance and identification tests may also be included to verify the physical characteristics.
