| area under curve | A statistical means of summarizing information from a series of measurements on one individual. It is frequently used in clinical pharmacology where the auc from serum levels can be interpreted as the total uptake of whatever has been administered. As a plot of the concentration of a drug against time, after a single dose of medicine, producing a standard shape curve, it is a means of comparing the bioavailability of the same drug made by different companies. (12 Dec 1998) |
| area under the curve | A measure of how much of a drug reaches the bloodstream in a set period of time, usually 24 hours. AUC is calculated by plotting drug blood concentration at various times during a 24-hour or longer period and then measuring the area under the curve between 0 and 24 hours as shown in the figure to the right.

| areal cover | <botany, ecology> A measure of dominance that defines the degree to which above ground portions of plants cover the ground surface, it is possible for the total areal cover for all strata combined in a community or for single stratum to exceed 100 percent because: most plant communities consist of two or more vegetative strata. Areal cover is estimated by vegetative layer, and foliage within a single layer may overlap. (09 Oct 1997) |

| arecoline | <chemical> An alkaloid obtained from the betel nut (areca catechu), fruit of a palm tree. It is an agonist at both muscarinic and nicotinic acetycholine receptors. It is used in the form of various salts as a ganglionic stimulant, a parasympathomimetic, and a vermifuge, especially in veterinary practice. It has been used as a euphoriant in the pacific islands. Pharmacological action: ganglionic stimulants, muscarinic agonist, nicotinic agonists, parasympathomimetic. Chemical name: 3-Pyridinecarboxylic acid, 1,2,5,6-tetrahydro-1-methyl-, methyl ester (12 Dec 1998) |
