The ‘full tolerance coverage method’ is introduced as a coverage estimation approach for assessing the uniformity of dosage units from large sample sizes, ensuring that no dosage unit exceeds the specification range.
Control of Quality Records in the Pharmaceutical Industry
November 1st 2002The security of documents in the pharmaceutical industry has become a critical issue since the advent of electronic data transfer. Companies in Europe must comply with 21 CFR Part 11 if they sell in the US. The regulations also require that secure, computer-generated, time-stamped audit trails are used to record the date and time of operator entries and actions that create, modify or delete electronic records. In particular, the record change must not obscure previously recorded information.
The Role of 21 CFR Part 11 in the Laboratory
October 1st 2002The benefits of using computers and electronic records are proven in most fields of modern-day work, none more so than in laboratories. The opportunities for automation have improved productivity; the computational abilities have increased the accuracy of scientific data and allowed previously difficult or impossible analytical techniques to become routine affairs. This, in turn, has led to huge advances in drug discovery and in the chemical, biochemical and physical analysis of drugs and patients.
IMS Limit Test Improves Cleaning Verification and Method Development
October 1st 2002A limit test using ion mobility spectrometry (IMS) has the potential to dramatically reduce the time required for cleaning verification and cleaning method development. The traditional approach to cleaning verification, often using HPLC, is relatively resource intensive and can lead to significant delays in reporting results. The main advantage of IMS is that results are seen virtually instantaneously, so any necessary re-measurement can be done very quickly. If the results demonstrate cleanliness, production can resume in a matter of hours not days.
An Overview of the Validation Approach for Moist Heat Sterilization, Part I
September 2nd 2002Part I of this article discusses examples for cycle types used in moist heat sterilization, parameter requirements for a standard cycle as defined by pharmacopeias, methods used to design sterilization cycles, and various approaches used to measure the efficiency of the sterilization process.
Validation Changes to the USP Assay Method for Ibuprofen Tablets
March 1st 2002This study investigated the effectiveness of the direct extraction of tablets and shaking time on the disintegration of tablets, solubilization, and recovery of ibuprofen from tablets of various formulations, strengths, and spiked placebo.
