Effective dose (pharmacology) In pharmacology, an effective dose (ED) or effective concentration (EC) is the dose or concentration of a drug that produces a biological response. [1][2] The term "effective dose" is used when measurements are taken in vivo, while "effective concentration" is used when the measurements are taken in vitro. [3]
Threshold dose is the minimum dose of drug that triggers minimal detectable biological effect in an animal. [1] At extremely low doses, biological responses are absent for some of the drugs. The increase in dose above threshold dose induces an increase in the percentage of biological responses. [ 2 ]
Trazodone, sold under many brand names, [ 1 ] is an antidepressant medication, [ 20 ] used to treat major depressive disorder, anxiety disorders, and insomnia. [ 20 ] It is a phenylpiperazine compound of the serotonin antagonist and reuptake inhibitor (SARI) class. [ 21 ][ 22 ] The medication is taken orally.
Dosage (pharmacology) In pharmacology and medicine, dosage refers to the prescribed regimen for administering a medication or substance, encompassing the amount, frequency, and duration of use. [1] It is distinct from dose, which denotes a single, specific quantity of a drug or substance given at one time. [2]
Naltrexone at a dose of 100 mg/day has been found to achieve 87% and 92% brain occupancy of the KOR in different studies. [85] [84] [86] Per simulation, a lower dose of naltrexone of 25 mg/day might be expected to achieve around 60% brain occupancy of the KOR but still close to 90% occupancy of the MOR. [84]
Aribit (Aripiprazole) tablets. Aripiprazole, sold under the brand names Abilify and Aristada, among others, is an atypical antipsychotic. [8] It is primarily used in the treatment of schizophrenia and bipolar disorder; [8] other uses include as an add-on treatment in major depressive disorder and obsessive–compulsive disorder (OCD), tic disorders, and irritability associated with autism. [8]
Mercaptopurine (6-MP), sold under the brand name Purinethol among others, is a medication used for cancer and autoimmune diseases. [2] Specifically it is used to treat acute lymphocytic leukemia (ALL), acute promyelocytic leukemia (APL), Crohn's disease, and ulcerative colitis.
Therapeutic drug monitoring (TDM) is a branch of clinical chemistry and clinical pharmacology that specializes in the measurement of medication levels in blood. Its main focus is on drugs with a narrow therapeutic range, i.e. drugs that can easily be under- or overdosed. [ 1 ] TDM aimed at improving patient care by individually adjusting the ...
