Portal:Pharmacy and Pharmacology/Intro
Welcome to the Pharmacy and Pharmacology Portal! The purpose of this page is to organize many of the pharmacology and drug-related articles on Wikipedia, to highlight some of the best articles, and to point out some of the recent activities and developments of WikiProject Pharmacology.
Pharmacology (in Greek: pharmacon (φάρμακον) meaning drug, and logos (λόγος) meaning science) is the study of how substances interact with living organisms to produce a change in function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties, interactions, toxicology, therapies, medical applications, and antipathogenic capabilities.
Pharmacy (from the Greek φάρμακον = drug) is a transitional field between the health sciences and the chemical sciences, as well as the profession charged with ensuring the safe use of medications. Traditionally, pharmacists have compounded and dispensed medications based on prescriptions from physicians. More recently, pharmacy has come to include other services related to patient care, including clinical practice, medication review, and drug information. Some of these new pharmaceutical roles are now mandated by law in various legislatures. Pharmacists, therefore, are drug therapy experts, and the primary health professionals who optimize medication management to produce positive health outcomes.
The field of pharmacy can generally be divided into three main disciplines:
- Pharmaceutics concerns on how to convert medication and drugs to suitable drug dosage forms.
- Pharmaceutical Sciences includes pharmaceutical chemistry, pharmacognosy, phytochemistry and pharmacology.
- Pharmacy practice concerns dispensing medication correctly. In the late 20th century, this field has developed into hospital pharmacy and clinical pharmacy. All of these fields are concentrated on optimizing patient care.
Inside every branch of pharmacy are many specialized branches related to many scientific disciplines. This makes pharmaceuticals related to the majority of pure and applied sciences. For example, medicinal chemistry can be divided into: ADME, bioavailability, chemogenomics, drug design, drug discovery, enzyme inhibition, mechanism of action, pharmacodynamics, pharmacokinetics, pharmacology, pharmacophore perception, Quantitative Structure-Activity Relationships, and Structure-Activity Relationships.
Biology (including molecular biology and biochemistry), physiology, organic chemistry, microbiology, parasitology, and also botany are all related in some way to the pharmaceutical sciences. Recently, the field of drug discovery and drug design has developed with new technologies invented in other fields, such as bioinformatics, cheminformatics, computational chemistry, genetics, pharmacogenomics, and proteomics.
