From Library Journal In this revised and updated version of his Essential Guide to Nonprescription Drugs ( LJ 4/1/83)， Zimmerman rates the safety and efficacy of the active ingredients in nonprescription medications， relying on data from the FDA's Over-the-Counter Drug Review. Each chapter covers a general area such as "eye-care aids" or "toothache relievers" and contains background information on the ailments， descriptions of the active ingredients used to treat them， and charts rating the brand-name products. The index provides access by brand names and active ingredients as well as symptoms. Much more useful to the consumer than the Physicians Desk Reference for Nonprescription Drugs (Practice Management Information Corp.， 1991)， because it evaluates and compares various products used to treat the same condition， this book is recommended for public libraries.- Kathleen McQuiston， Philadel phia Coll. of Pharmacy & ScienceCopyright 1993 Reed Business Information， Inc. --This text refers to an out of print or unavailable edition of this title.
