Body surface area. In physiology and medicine, the body surface area ( BSA) is the measured or calculated surface area of a human body. For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. Nevertheless, there have been several important critiques of the ...
The lateral surface of a right cylinder is the meeting of the generatrices. [3] It can be obtained by the product between the length of the circumference of the base and the height of the cylinder. Therefore, the lateral surface area is given by: =. [2] Where: represents the lateral surface area of the cylinder; is approximately 3.14;
Clark's rule. Clark's rule is a medical term referring to a mathematical formula used to calculate the proper dosage of medicine for children aged 2–17 based on the weight of the patient and the appropriate adult dose. [ 1] The formula was named after Cecil Belfield Clarke (1894–1970), a Barbadian physician who practiced throughout the UK ...
Equianalgesic. An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [ 1] Tables of this general type are also available for ...
The area of the side is known as the lateral area, L. An open cylinder does not include either top or bottom elements, and therefore has surface area (lateral area) = The surface area of the solid right circular cylinder is made up the sum of all three components: top, bottom and side.
In the field of pharmacokinetics, the area under the curve ( AUC) is the definite integral of the concentration of a drug in blood plasma as a function of time (this can be done using liquid chromatography–mass spectrometry [ 1] ). In practice, the drug concentration is measured at certain discrete points in time and the trapezoidal rule is ...
Absorption (pharmacology) Absorption is the journey of a drug travelling from the site of administration to the site of action. [ 1 ][ 2 ] The drug travels by some route of administration ( oral, topical-dermal, etc.) in a chosen dosage form (e.g., tablets, capsules, or in solution ). [ 3 ] Absorption by some other routes, such as intravenous ...
The size, and hence the surface area of a particle, can be related to the physical, chemical and pharmacological properties of drugs. Clinically, the particle size of a drug can affect its release from dosage forms that are administered orally, parenterally, rectally and topically. The successful formulation of suspensions, emulsions and ...
