Introduction The compendia monographs are generally considered reliable sources for the methods of analysis of both the raw materials (Active Pharmaceutical Ingredients, API’s and Excipients) and Finished Drug Products (FDP). However, because there are so many factors involved during the analysis, this includes for example the reagents grades and suppliers, different instruments variations, and the analysis personnel, therefore, double check of the mentioned method of analysis to confirm that it will meet the predefined requirements and the purposes it was created for is mandatory. This process of confirmation is known as either Verification or Validation BP and USP general chapters are almost the same concerning method of analysis validation, and have only minor differences mainly in the terminology; the ICH however is the harmonized where both terms are used and clarified. Verification vs. Validation The Method Validation is the whole process of performing all analytical tests (known as Analytical Performance Characteristics, APC’s) in order to ensure that the method will be applied successfully every time it is run. This should be done to all methods and procedures. Newly in house developed methods should follow the full validation scheme; however, the pharmacopeia ones need to be checked first whether full validation is required or only verification will be sufficient. The Verification process is defined as assessing selected Analytical Performance Characteristics, to generate appropriate relevant data rather than repeating the whole validation process. It is also part of the requirements in the 21 CFR 211.194(a)(2) in the current Good Manufacturing Practices and by the FDA regulations. Accordingly, the compendia analytic... ... middle of paper ... ...ques, the rest of the components can be separated during the analysis itself. It is a difficult to assure in chromatography whether the peaks within a sample are pure or consist of more than one compound (overlapped peaks). The analyst should know how many compounds are in the sample which is not always possible. Therefore, the target compound peak (e.g., API or a specific impurity) should be evaluated for purity. UV-visible diode-array detectors and mass spectrometers play are employed during this phase of the method validation. In case of the assay, demonstrating specificity requires the procedure to prove that it is unaffected by the presence of impurities or excipients. In practice, this can be done by spiking the drug product with the appropriate levels of impurities or excipients, and check if the obtained peaks are representative of only one compound or not.
The analysis is therefore one of the most effective methods of ensuring that each drug being prescribed to patients is safe. It also ensures that all drug components are understood in terms of their structure and chemical behavior. This understanding is very important in the manufacture of drugs and other pharmaceutical products.

In Order to formulate and create that accurate and correct final result. There must be at least one mistake that you came across in which helped guide you to that final error less result. To have that happen you must have in mind that you will make mistakes and you will be ok with that happening. For every lab conclusion there needs to be at least three sources of error. The three sources of error that occurred throughout the entire experiment in which was performed.

What is the purpose of a nursing research study if you do not have validity and reliability? In this article, Identifying a Relationship Between Physical Frailty and Heart Failure Symptoms, a cross section study is done to correlate the relationship between HF symptoms (sleep disturbances, pain, anxiety, dyspnea, depression) and physical frailty.(Denfeld, Winters-Stone, Mudd, Hiatt, & Lee, 2017). Patients with HF were asked a range of questions and given subjective scales where they self reported the previously mentioned symptoms. The ultimate benefit of correlating this would be to prevent frailty therefore reducing the severity of these symptoms.
In life, we often look to others for validation, our family, friends, or even strangers. Throughout life, as we evolve, validation plays a prominent role in all of our lives. From a young age we are taught to see approval and validation from others. In fact, as children, we are taught to look to our parents for a smile or a nod of reassurance and approval for our choices. This teaches us that throughout life, we should look to others for their validation for confirmation. From a young age we are taught to compulsively seek others approval, however, when evaluating why we seek validation, we find that validation and approval is found within.

The process of analysis is classified on the basis of information used and ‘modus operandi’ of analysis. The classification is as under:
...e, the British Pharmacopeia Finished Drug Product method of analysis in the monograph was taken as granted without being checked for its appropriateness, in this situation Verification should have been carried to check at least the Accuracy, Precision and Specificity of the BP method for the finished product.
Measurements are only reliable to the extent that they can be repeated and that any random influence that can make measurements different is a source of error. There are many ways to measure both reliability and validity. Some of the ways to measure reliability is test-retest, parallel form, and split-half method. The test-retest measures the results given when the same test is given at different times. Once the both test are administered the results are then compared for consistency.
In the following essay I will attempt to attack John H. Hick's view of verification, and how it can be processed within steps. I will expand on how religion, and everything that is contained within it, can't be verified at all. Although Hick discussed the problems of verification in Chapter 8 "The Problems of Verification" in Philosophy of Religion, he lacked discussion on crucial elements, discussing the problem of verifying religion as a whole.
The Biopharmaceutics Classification System (BCS) is a scientific framework that is used to classify the drug substances on the basis of their intestinal permeability and aqueous solubility . BCS is known as a drug product regulation tool for scale-up and post-approval challenges in worldwide . The objective of the BCS is to provide a regulatory tool to predict in vivo performance of drug products by conducting in vitro dissolution tests or measurements of permeability and solubility.
