what are the most important characteristics of a drug
Drug design Drug design, often referred to as rational drug design or simply rational design, is the inventive process of finding new medications based on the knowledge of a biological target.[1] The drug is most commonly an organic small molecule that activates or inhibits the function of a biomolecule such as a protein, which in turn results in a therapeutic benefit to the patient. In the most basic sense, drug design involves the design of molecules that are complementary in shape and charge to the biomolecular target with which they interact and therefore will bind to it. Drug design frequently but not necessarily relies on computer modeling techniques.[2] This type of modeling is sometimes referred to as computer-aided drug design. Finally, drug design that relies on the knowledge of the three-dimensional structure of the biomolecular target is known as structure-based drug design.[2] In addition to small molecules, biopharmaceuticals and especially therapeutic antibodies are an increasingly important class of drugs and computational methods for improving the affinity, selectivity, and stability of these protein-based therapeutics have also been developed.[3]
Comprehensive Drug Abuse Prevention and Control Act of 1970 The Comprehensive Drug Abuse Prevention and Control Act of 1970, Pub.L. 91–513, 84 Stat. 1236, enacted October 27, 1970, is a United States federal law that, with subsequent modifications, requires the pharmaceutical industry to maintain physical security and strict record keeping for certain types of drugs.[1] Controlled substances are divided into five schedules (or classes) on the basis of their potential for abuse, accepted medical use, and accepted safety under medical supervision. Substances in Schedule I have a high potential for abuse, no accredited medical use, and a lack of accepted safety. From Schedules II to V, substances decrease in potential for abuse. The schedule a substance is placed in determines how it must be controlled. Prescriptions for drugs in all schedules must bear the physician's federal Drug Enforcement Administration (DEA) license number, but some drugs in Schedule V do not require a prescription. State schedules may vary from federal schedules.
