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]
That immediately gets the drug's concentration in the body up to the therapeutically-useful level. First day: 1000 mg; the body clears 100 mg, leaving 900 mg. On the second day, the patient takes 100 mg, bringing the level back to 1000 mg; the body clears 100 mg overnight, still leaving 900 mg, and so forth.
TDM interpretation: an anticancer drug is given to a patient at a dosage of 400 mg every day at 8:00 am. A TDM sample is obtained at 6:00 am, showing a drug concentration of 0.46 mg/L. 1) Regarding “normality”, the result is around the 25th percentile, suggesting a rather high drug clearance in this patient.
[57] [58] See for instance Table 2 vs Table 11 in the Chem Rev paper, Table 2 lists in vitro pIC 50 values matching those below, while Table 11 has pEC 50 values derived from in vivo assays in mice, which show the same activity trends but cannot be compared directly, and includes data for compounds such as diclazepam and flubromazepam which are ...
[213] [97] [12] [10] Estradiol patches delivering a daily dosage of 0.05 mg (50 μg) achieve mean estradiol and estrone levels of 30 to 65 pg/mL and 40 to 45 pg/mL, respectively, while a daily dosage of 0.1 mg (100 μg) attains respective mean levels of 50 to 90 pg/mL and 30 to 65 pg/mL of estradiol and estrone.

A preliminary study of ovulation inhibition in women found that oral CEEs was 33% effective at 1.25 mg/day and 94% at 3.75 mg/day. [63] [64] A dosage of oral CEEs of 2.5 mg three times daily (7.5 mg/day total) has been found to suppress total testosterone levels in men to an equivalent extent as 3 mg/day oral diethylstilbestrol, which is the ...
English-speaking countries also used a system of units of fluid measure, or in modern terminology volume units, based on the apothecaries' system. Originally, the terms and symbols used to describe the volume measurements of liquids were the same as or similar to those used to describe weight measurements of solids [33] (for example, the pound by weight and the fluid pint were both referred to ...
The solubility of mitragynine from kratom in neutral-pH and alkaline water is very low (0.0187 mg/ml at pH 9). [20] The solubility of mitragynine in acidic water is higher (3.5 mg/ml at pH 4), however, this alkaloid can become unstable, so certain products, such as low-pH beverages, have a very short shelf life.
