Paradoxical disinhibition is a paradoxical reaction, an uncommon but recognized phenomenon, characterized by acute excitement and an altered mental state, caused by benzodiazepines. The mechanism is poorly known, but the most accepted theory is that it occurs secondary to inhibition of the restraining influences of the cortex and frontal lobe ...
A paradoxical reaction (or paradoxical effect) is an effect of a chemical substance, such as a medical drug, that is opposite to what would usually be expected. An example of a paradoxical reaction is pain caused by a pain relief medication .
Paradoxical behavior is often not recalled by the patient due to the amnesia-producing properties of the drug. In extreme situations, flumazenil can be administered to inhibit or reverse the effects of midazolam. Antipsychotic medications, such as haloperidol, have also been used for this purpose. [47] Midazolam is known to cause respiratory ...
Paradoxical reactions are rare in the general population, with an incidence rate below 1% and similar to placebo. [ 8 ] [ 120 ] However, they occur with greater frequency in recreational abusers, individuals with borderline personality disorder , children, and patients on high-dosage regimes.
These effects are paradoxical to the use of benzodiazepines, both clinically and non-medically, in management of mental health conditions. [44] [45] Long-term benzodiazepine use may lead to the creation or exacerbation of physical and mental health conditions, which improve after six or more months of abstinence.
Immune reconstitution inflammatory syndrome (IRIS) is a condition seen in some cases of HIV/AIDS or immunosuppression, in which the immune system begins to recover, but then responds to a previously acquired opportunistic infection with an overwhelming inflammatory response that paradoxically makes the symptoms of infection worse.
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
In adverse drug reactions involving overdoses, the toxic effect is simply an extension of the pharmacological effect (Type A adverse drug reactions). On the other hand, clinical symptoms of idiosyncratic drug reactions (Type B adverse drug reactions) are different from the pharmacological effect of the drug.
