Drug tolerance or drug insensitivity is a pharmacological concept describing subjects' reduced reaction to a drug following its repeated use. Increasing its dosage may re-amplify the drug's effects; however, this may accelerate tolerance, further reducing the drug's effects.
Tachyphylaxis (Greek ταχύς, tachys, "rapid", and φύλαξις, phylaxis, "protection") is a medical term describing an acute, sudden decrease in response to a drug after its administration (i.e., a rapid and short-term onset of drug tolerance). [1] It can occur after an initial dose or after a series of small doses.
Tolerability refers to the degree to which overt adverse effects of a drug can be tolerated by a patient. [1] Tolerability of a particular drug can be discussed in a general sense, or it can be a quantifiable measurement as part of a clinical study.
For example, a patient could possess a genetic defect in a drug metabolizing enzyme in the cytochrome P450 superfamily. While most individuals will possess the effective metabolizing machinery, a person with a defect will have a difficult time trying to clear the drug from their system. Thus, the drug will accumulate within the blood to higher ...
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.
ADT tachyphylaxis specifically occurs in patients experiencing depression who are using SSRIs and Monoamine Oxidase Inhibitors (MAOIs). Currently, SSRIs are the preferred treatment for depression among clinicians, as MAOIs, despite being very effective, require a few dietary restrictions and some caution when taking with other medications due to the potential for interactions capable of ...
