This book provides a step-by-step guide to simple methods for verifying the identity of commonly used pharmaceutical substances and dosage forms. The basic tests described can also be used to detect mislabeled, substandard, or counterfeit products when the labeling or physical attributes give rise to doubt. Intended for use in developing countries, where resources and specialized skills may be scarce, all tests rely on a limited range of easily available reagents and equipment and need not be performed in a fully equipped laboratory or by persons with specialized training in pharmacy or chemistry. The book describes tests for 23 pharmaceutical substances and 58 pharmaceutical dosage forms, most of which are included in the WHO Model List of Essential Drugs. Basic tests for confirming the identity of four commonly used medicinal plant materials are also included. As stressed in the text, these tests, which merely confirm identity, are intended for use as primary screening tools and may need to be followed, in cases of adverse test results, by a full pharmacopoeial analysis. The book opens with a brief description of the importance of basic tests as one of the many steps needed to ensure a supply of safe and effective drugs. Chapter two describes several collections of more sophisticated tests, including volumetric or spectrophotometric analysis and thin-layer chromatography, that can be useful in the primary screening of imported pharmaceutical substances, and dosage forms. Information on how to obtain and use these guides to tests, which have not been published by WHO is also provided. Against this background, the main part of the book sets out test procedures for verifying the identity of selected pharmaceutical substances, pharmaceutical dosage forms, and medicinal plant materials. The book concludes with a cumulative index of test procedures described here and in the related WHO publications "Basic Tests for Pharmaceutical Substances" and "Basic Tests for Pharmaceutical Dosage Forms".

Guides readers on the proper use of in vitro drug release methodologies in order to evaluate the performance of special dosage forms In the last decade, the application of drug release testing has widened to a variety of novel/special dosage forms. In order to predict the in vivo behavior of such dosage forms, the design and development of the in vitro test methods need to take into account various aspects, including the dosage form design and the conditions at the site of application and the site of drug release. This unique book is the first to cover the field of in vitro release testing of special dosage forms in one volume. Featuring contributions from an international team of experts, it presents the state of the art of the use of in vitro drug release methodologies for assessing special dosage forms’ performances and describes the different techniques required for each one. In Vitro Drug Release Testing of Special Dosage Forms covers the in vitro release testing of: lipid based oral formulations; chewable oral drug products; injectables; drug eluting stents; inhalation products; transdermal formulations; topical formulations; vaginal and rectal delivery systems and ophthalmics. The book concludes with a look at regulatory aspects. Covers both oral and non-oral dosage forms Describes current regulatory conditions for in vitro drug release testing Features contributions from well respected global experts in dissolution testing In Vitro Drug Release Testing of Special Dosage Forms will find a place on the bookshelves of anyone working with special dosage forms, dissolution testing, drug formulation and delivery, pharmaceutics, and regulatory affairs.

This book is intended to serve as a resource for analysts in developing and troubleshooting sample preparation methods. These are critical activities in providing accurate and reliable data throughout the lifecycle of a drug product. This book is divided into four parts: • Part One covers dosage form and diluent properties that impact sample preparation of pharmaceutical dosage forms and the importance of sampling considerations in generating data representative of the drug product batch. • Part Two reviews specific sample preparation techniques typically used with pharmaceutical dosage forms. • Part Three discusses sample preparation method development for different types of dosage forms including addressing drug excipient interactions and post extraction considerations, as well as method validation and applying Quality by Design (QbD) principles to sample preparation methods. • Part Four examines additional topics in sample preparation including automation, investigating aberrant potency results, green chemistry considerations for sample preparation and the ideal case where no sample preparation is required for sample analysis.

Pain is both a symptom and a disease. It manifests in multiple forms and its treatment is complex. Physical, social, economic, and emotional consequences of pain can impair an individual's overall health, well-being, productivity, and relationships in myriad ways. The impact of pain at a population level is vast and, while estimates differ, the Centers for Disease Control and Prevention reported that 50 million U.S. adults are living in pain. In terms of pain's global impact, estimates suggest the problem affects approximately 1 in 5 adults across the world, with nearly 1 in 10 adults newly diagnosed with chronic pain each year. In recent years, the issues surrounding the complexity of pain management have contributed to increased demand for alternative strategies for treating pain. One such strategy is to expand use of topical pain medicationsâ€"medications applied to intact skin. This nonoral route of administration for pain medication has the potential benefit, in theory, of local activity and fewer systemic side effects. Compounding is an age-old pharmaceutical practice of combining, mixing, or adjusting ingredients to create a tailored medication to meet the needs of a patient. The aim of compounding, historically, has been to provide patients with access to therapeutic alternatives that are safe and effective, especially for people with clinical needs that cannot otherwise be met by commercially available FDA-approved drugs. Compounded Topical Pain Creams explores issues regarding the safety and effectiveness of the ingredients in these pain creams. This report analyzes the available scientific data relating to the ingredients used in compounded topical pain creams and offers recommendations regarding the treatment of patients.
