ABSTRACT: The present study of concurrent process validation delivers an extraordinary degree of quality assurance that a specific process for manufacturing of Glibenclamide Tablets will consistently manufacture a product that meets its predetermined quality attributes and specifications. Glibenclamide is generally suggested for the treatment of type II diabetes mellitus and it is mainly a sulfonylurea derivative. It mainly comprises the stages to be followed to evaluate and qualify the acceptability of the manufacturing process of Glibenclamide 2.5 mg tablets. The process is limited to the three batches H, I, and J manufactured of specific batch size with the help of specified equipment’s and different quality control parameters for tablets. It involves all parameters related to each step were evaluated by the respective standard test involved in the manufacturing. All analytical results of each stage were found to be within the acceptable limit and criteria. Other tests related to compression such as hardness, thickness, disintegration and dissolution for all three batches were also found within the acceptable limit.
Keywords: Glibenclamide, Assay, Concurrent, Tablets
INTRODUCTION: Validation is defined as the process of founding through a documented database program, which provides a high degree of assurance that a specific process will constantly produce a product meeting its pre-determined specifications and critical quality attributes. The word validation simply means ‘assessment of validity’ or ‘action of proving effectiveness’ a validated manufacturing process is one, which has been proved to do what it purports to or is represented to do.
Validation essentially contains process qualification (the qualification of materials, equipment, system, buildings and personnel, i.e., Design Qualification, Installation Qualification, Operation Qualification, Performance Qualification).
Process Validation is defined as the collection and evolution of data from the process design stage throughout production, which establishes scientific evidence that a process can consistently deliver quality products. It assures Quality, Safety and efficacy. The process validation is the analysis of data collected throughout the design and manufacturing of a product to endorse that the process gives consistent production of products with a given standard. The main aim of process validation of Glibenclamide is to ensure various inputs lead to consistent and great quality productions and its continuing process that must be regularly improved as manufacturing feedback is gathered. Glibenclamide, also known as glyburide, is an anti-diabetic drug in the class of medications known as sulfonylurea and thoroughly related to sulfonamide antibiotics. Glibenclamide, it’s a second-generation sulfonylurea commonly used to treat type II diabetes mellitus. Glibenclamide was firstly granted FDA approval on May 01, 1984 and formulation with metformin was granted FDA approval on July 31, 2000. Glibenclamide is a sulfonylurea derivative and is recommended for the treatment of type II diabetes mellitus. Glibenclamide goes through the hepatic first-pass effect in its oral administration, such that only 45% of the drug is absorbed and considering its short half-life, the persistent has to take the drug in several divided doses to maintain the desired therapeutic effect. Gastrointestinal adverse effects of Glibenclamide have been reported for the drug, which decreases the patients’ compliance.
Process Validation Should Proceed in the following Condition
- Processes remained finished products tests are poor
- When implementing new processes for manufacturing of the product
- When new equipment’s are installed or used in the manufacturing process
- Process and equipment which are having altered suit changing the priority
