The reasons for which pharmaceutical compounding is the focus of intense state and federal scrutiny are now well known. Compounders are faced with an ever-increasing need to prove, by objective standards, the safety, purity, and potency of the formulations they dispense. They must also demonstrate their compliance with regulations often based on current good compounding practices designed for the pharmaceutical industry. ⋯ This article describes the author's experience with an unannounced United States Food and Drug Administration inspection of his 503A compounding facility and his response to the findings. Readers will learn what to expect during such an inspection, how to prepare for that event, and how to achieve an excellent outcome. Those who would like more information about any of the topics presented are invited to contact the author at the address provided at the close of this article.

Pharmacists use various sources for obtaining the active pharmaceutical ingredient for compounding medications. In many cases, it is the pure drug (United States Pharmacopeia, National Formulary, or similar grade); in some cases, it can be a commercial dosage form; and, in some cases, it may be a dilution or concentrate. ⋯ Presented within this article are new sources of active pharmaceutical ingredients that are now available to aid pharmacists in meeting future United States Pharmacopeia <800> standards. It is critical that the pharmacist be aware of the strength of the drug and any other excipients that may be available.

Analytical testing will no doubt become a more important part of pharmaceutical compounding as the public and regulatory agencies demand increasing documentation of the quality of compounded preparations. Compounding pharmacists must decide what types of testing and what amount of testing to include in their quality-control programs, and whether testing should be done in-house or outsourced. Like pharmaceutical compounding, analytical testing should be performed only by those who are appropriately trained and qualified. This article discusses the analytical methods that are used in quality control in a compounding pharmacy.

Biopharmaceutics studies the relationship between the drug product and what happens after the product is administered. Since the majority of injectables are administered by the intravenous route, thus avoiding the need for drug absorption, not many articles are published compared to other routes of drug administration. However, other routes of administration for drug injection are becoming more frequent because of greater commercial availability of sustained- and controlled-release drug delivery systems. This article reviews basic principles of drug absorption, distribution, metabolism, and elimination of injectable drugs and certain physicochemical and physiological factors affecting injectable drug biopharmaceutics.

Ophthalmic preparations are used to treat allergies, bacterial and viral infections, glaucoma, and numerous other eye conditions. When the eye's natural defensive mechanisms are compromised or overcome, an ophthalmic preparation, in a solution, suspension, or ointment form, may be indicated, with solutions being the most common form used to deliver a drug to the eye. This article discusses ophthalmic suspensions and ointments and represents part 2 of a 2-part article, the first of which discussed ophthalmic solutions.
