Redux

Redux, also marketed under the name Redux, is a serotoninergic anorectic drug. It was for some years in the mid-1990s approved by the United States Food and Drug Administration for the purposes of weight loss. However, following multiple concerns about the cardiovascular side-effects of the drug, such approval was withdrawn.

Redux - Pharmacology:

Redux binds to the serotonin reuptake pump. This causes inhbition of serotonin uptake and release of serotonin. The increased levels of serotonin lead to greater serotonin receptor activation which in turn lead to enhancement of serotoninergic transmission in the centres of feeding behavior located in the hypothalamus. This suppresses the appetite for carbohydrates.

Redux Interactions

In patients receiving nonselective monoamine oxidase inhibitors (MAOIs) (e.g., selegiline hydrochloride) in combination with serotoninergic agents (e.g., fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine), there have been reports of serious, sometimes fatal, reactions. Because dexfenfluramine is a serotonin releaser and reuptake inhibitor, dexfenfluramine should not be used concomitantly with a MAO inhibitor.

At least 14 days should elapse between discontinuation of a MAO inhibitor and initiation of treatment with dexfenfluramine. At least 3 weeks should elapse between discontinuation of dexfenfluramine and initiation of treatment with a MAO inhibitor.

A rare, but serious, constellation of symptoms, termed "serotonin syndrome," has been reported with the concomitant use of selective serotonin reuptake inhibitors (SSRIs) and agents for migraine therapy, such as Imitrex (sumatriptan succinate) and dihydroergotamine. The syndrome requires immediate medical attention and may include one or more of the following symptoms: excitement, hypomania, restlessness, loss of consciousness, confusion, disorientation, anxiety, agitation, motor weakness, myoclonus, tremor, hemiballismus, hyperreflexia, ataxia, dysarthria, incoordination, hyperthermia, shivering, pupillary dilation, diaphoresis, emesis, and tachycardia. Redux should not be administered with other serotoninergic agents. The appropriate interval between administration of these agents and dexfenfluramine has not been established. The use of dexfenfluramine with other CNS-active drugs has not been systematically evaluated; consequently, caution is advised if dexfenfluramine and such drugs are prescribed concurrently.

Redux Contraindications

Redux is contraindicated in patients with diagnosed pulmonary hypertension. Redux is contraindicated in patients receiving monoamine oxidase inhibitors (see DRUG INTERACTIONS). Redux is contraindicated in patients with hypersensitivity to dexfenfluramine, fenfluramine, or related compounds.
