To perform a D-test, an agar plate is inoculated with the bacteria in question and two drug-impregnated disks (one with erythromycin, one with clindamycin) are placed 15–20 mm apart on the plate. If the area of inhibition around the clindamycin disk is D-shaped, the test result is positive.
The procedure is to take the child's weight in pounds, divide by 150 lb, and multiply the fractional result by the adult dose to find the equivalent child dosage.For example, if an adult dose of medication calls for 30 mg and the child weighs 30 lb, divide the weight by 150 (30/150) to obtain 1/5 and multiply 1/5 times 30 mg to get 6 mg.
Typically, different doses are recommended for children 6 years and under, for children aged 6 to 12 years, and for persons 12 years and older, but outside of those ranges the guidance is slim. [2] This can lead to serial under- or over-dosing, as smaller people take more than they should and larger people take less.
Benzoyl peroxide also kills C. acnes, but by releasing free radical oxygen species, thus oxidizing bacterial proteins. Also, it dries out the area by reducing sebum production, prevents clogged pores, and is a keratolytic agent. [16] Since benzoyl peroxide is an oxidizer, not an antibiotic, it is not subject to C. acnes resistance unlike ...
At the time, the RDD of rosuvastatin was similar to its DDD (12.6 mg vs 10mg), but the RDD of atorvastatin was twice its DDD (20.6 mg vs 10mg). The DDD of atorvastatin was revised in 2009 to 20mg. [4] The Canadian Patented Medicine Prices Review Board analysed the use of DDD for drug utilisation and cost analysis and offered recommendations ...
The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...
Committed equivalent dose, H T (t) is the time integral of the equivalent dose rate in a particular tissue or organ that will be received by an individual following intake of radioactive material into the body by a Reference Person, where s is the integration time in years. [13]
Committed effective dose equivalent (CEDE) as defined in Title 10, Section 20.1003, of the Code of Federal Regulations of the USA the CEDE dose (HE,50) is the sum of the products of the committed dose equivalents for each of the body organs or tissues that are irradiated multiplied by the weighting factors (WT) applicable to each of those ...
