Stahl’s Essential Psychopharmacology is a suite of products that began some 20 years ago as a published offshoot of Dr. Stahl’s lectures about disease mechanisms and drug actions. Consisting of not only a range of books but also an online service, a journal, and related CME, it is a complete resource for psychiatrists, psychologists, primary care physicians, pharmacists, and nurse practitioners. Even patients and their families will find this array of products helpful in navigating the complex world of psychotropic drugs and their actions.
