Some useful principles and practices for modern drug therapy

The development of many new, potent, and highly effective drugs for use in drug therapy has in itself created a problem for the physician. Prior to 1935 there were relatively few potent, highly useful agents available for use in therapy. The physician soon became familiar with these few and was able to use them wisely and with considerable skill. Consequently, there were comparatively few iatrogenic reactions from drug therapy. Furthermore, physicians were so thoroughly acquainted with these drugs that they were able to secure the maximum benefit from them with a minimum of untoward effect.
