Drug discovery

Drug discovery is the way new drugs are discovered. Historically, drugs were widely available by identifying the active ingredients from traditional medicine or by accident. Subsequently, ancient pharmacology was used to investigate chemical libraries including small molecules, natural products, or extracted plants, and to obtain those with therapeutic effects. Since human DNA sequence, reverse pharmacology has found a cure for existing diseases by experimentation. Disease procedures, chemical tests, existing treatments with side effects, and new technologies promote drug availability.
