Equivalent dose is a dose quantity H representing the stochastic health effects of low levels of ionizing radiation on the human body ... 5.0 + 17.0·e −[ln(2·E)]²/6
[1] [2] It was estimated that equivalent effects would be expected with (S)-MDMA 100 mg, MDMA 125 mg, and (R)-MDMA 300 mg. [1] [2] The findings of the study were overall regarded as not supporting the hypothesis that (R)-MDMA would produce equivalent therapeutic effects as (S)-MDMA or MDMA whilst reducing safety concerns.
CDE is defined by the United States Nuclear Regulatory Commission in Title 10, Section 20.1003, of the Code of Federal Regulations (10 CFR 20.1003), such that "The Committed dose equivalent, CDE (H T,50) is the dose to some specific organ or tissue of reference (T) that will be received from an intake of radioactive material by an individual during the 50-year period following the intake".
The roentgen or röntgen (/ ˈ r ɛ n t ɡ ə n,-dʒ ə n, ˈ r ʌ n t-/; [2] symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air (statcoulomb per kilogram).
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]

SB-221284 is a selective serotonin 5-HT 2C and 5-HT 2B receptor antagonist which is used in scientific research. [1] [2] [3]Its affinities (K i) are 2.2 to 2.5 nM for the serotonin 5-HT 2C receptor, 2.5 to 12.6 nM for the serotonin 5-HT 2B receptor, and 398 to 550 nM for the serotonin 5-HT 2A receptor (where it is also an antagonist).
Cyproheptadine has been reported to block 85% of 5-HT 2 receptors in the human brain at a dose of 4 mg three times per day (12 mg/day total) and to block 95% of 5-HT 2 receptors in the human brain at a dose of 6 mg three times per day (18 mg/day total) as measured with positron emission tomography (PET).
