Route of administration

A route of administration in pharmacology and toxicology is the path by which a drug, fluid, poison, or other substance is taken into the body. Routes of administration are generally classified by the location at which the substance is applied. Common examples include oral and intravenous administration. Routes can also be classified based on where the target of action is. Action may be topical (local), enteral (system-wide effect, but delivered through the gastrointestinal tract), or parenteral (systemic action, but delivered by routes other than the GI tract).

Classification

Routes of administration are usually classified by application location (or exposition). The route or course the active substance takes from application location to the location where it has its target effect is usually rather a matter of pharmacokinetics (concerning the processes of uptake, distribution, and elimination of drugs). Nevertheless, some routes, especially the transdermal or transmucosal routes, are commonly referred to routes of administration. The location of the target effect of active substances are usually rather a matter of pharmacodynamics (concerning e.g. the physiological effects of drugs). Furthermore, there is also a classification of routes of administration that basically distinguishes whether the effect is local (in "topical" administration) or systemic (in "enteral" or "parenteral" administration).

Drug

A drug is any substance other than food, that when inhaled, injected, smoked, consumed, absorbed via a patch on the skin or dissolved under the tongue causes a physiological change in the body.

In pharmacology, a pharmaceutical drug or medicine, is a chemical substance used to treat, cure, prevent, diagnose a disease or promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders.

Pharmaceutical drugs are often classified into drug classes—groups of related drugs that have similar chemical structures, the same mechanism of action (binding to the same biological target), a related mode of action, and that are used to treat the same disease. The Anatomical Therapeutic Chemical Classification System (ATC), the most widely used drug classification system, assigns drugs a unique ATC code, which is an alphanumeric code that assigns it to specific drug classes within the ATC system. Another major classification system is the Biopharmaceutics Classification System. This classifies drugs according to their solubility and permeability or absorption properties.

Mourvèdre

Mourvèdre (also known as Mataró or Monastrell) is a red wine grape variety that is grown in many regions around the world including the Rhône and Provence regions of France, the Valencia and Jumilla denominación de origens of Spain, California and Washington State and the Australian regions of South Australia and New South Wales. In addition to making red varietal wines, Mourvèdre is a prominent component in "GSM" (Grenache, Syrah, and Mourvedre) blends. The variety is also used to make rosé and port-style fortified wines.

Mourvèdre tends to produce tannic wines that can be high in alcohol. The style of wine produced from the grapes varies greatly according to where it is produced, but according to wine expert Jancis Robinson Mourvèdre wines often have wild game and/or earthy notes to them, with soft red fruit flavors. According to wine expert Oz Clarke, young Mourvèdre can come across as faulted due to the reductive, sulfur notes and "farmyard-y" flavors that some wines can exhibit before those flavors mellow with age.

Drug (disambiguation)

A drug is any chemical substance other than a food or device that affects the function of living things. Drugs can be used to treat illness, relieve a symptom or modify a chemical process in the body for a specific purpose.
