Amphetamine [note 1] contracted from a lpha reverse tolerance m ethyl ph en et hyl amine is a potent central nervous system CNS stimulant that is used in the treatment of attention deficit hyperactivity disorder ADHDnarcolepsyand obesity. Amphetamine was discovered in and exists as two enantiomers: Amphetamine properly refers to a specific chemical, the racemic free basewhich is equal parts of the two enantiomers, levoamphetamine and reverse tolerance, in their pure amine forms. The term is adderall sensitization used informally to refer to any combination of the enantiomers, or to either of them alone. Historically, it has been used to treat nasal reverse tolerance and depression. Amphetamine is also used as an athletic performance enhancer and cognitive enhanceradderall sensitization recreationally as an aphrodisiac and euphoriant. It is a prescription drug in many countries, and unauthorized possession and distribution of amphetamine are often tightly valium same as xanax due "adderall sensitization" the significant health risks associated with recreational use.

Thereafter, its reverse tolerance is generally maintained for weeks, or perhaps months after the initial dosage with favorable results. Long-term users may report that the same 20 mg dose of Adderall is no longer providing the same reverse tolerance of focus and cognitive enhancement as it was during their first few months of usage. It is the tolerance induction that leads most Adderall users back to their doctors to report that their starting adderall sensitization is no longer "adderall sensitization" or effective. At this point, the doctor suggests increasing the dosage, perhaps to 40 mg should i drink alcohol while on accutane doubling the amount of psychostimulation.

Reverse tolerance or drug sensitization is a pharmacological concept describing subjects' increased reaction positive or negative to a drug following its repeated use. This is the opposite of drug tolerance or drug desensitization , in which the effect or the subject's reaction or will increase following its repeated use. The two notions are not incompatible, and tolerance may sometimes lead to reverse tolerance. For example, heavy drinkers initially develop tolerance to alcohol, requiring them to drink larger amounts to achieve a similar effect, but as excessive drinking can cause liver damage , this can then put this group at risk of intoxication when drinking even very small amounts of alcohol. In some cases drug sensitization may also refer to medical interventions e. From Wikipedia, the free encyclopedia. Addiction and dependence glossary [1] [2] [3] [4] addiction — a brain disorder characterized by compulsive engagement in rewarding stimuli despite adverse consequences addictive behavior — a behavior that is both rewarding and reinforcing addictive drug — a drug that is both rewarding and reinforcing dependence — an adaptive state associated with a withdrawal syndrome upon cessation of repeated exposure to a stimulus e.

Adderall , [note 1] Adderall XR Extended Release , and Mydayis are combination drugs containing four salts of the two enantiomers of amphetamine , a central nervous system CNS stimulant of the phenethylamine class. Adderall is used in the treatment of attention deficit hyperactivity disorder ADHD and narcolepsy. It is also used as an athletic performance enhancer and cognitive enhancer , and recreationally as an aphrodisiac and euphoriant. Adderall is generally well-tolerated and effective in treating the symptoms of ADHD and narcolepsy. At therapeutic doses, Adderall causes emotional and cognitive effects such as euphoria , change in desire for sex , increased wakefulness , and improved cognitive control.

Amphetamine-induced place preference in humans. Background The conditioned place preference procedure is a widely used animal adderall sensitization reverse of rewarding drug effects that, to date, has not tolerance tested in humans.

There is growing interest in Memantine which is a novel unique drug that acts on the glutamatergic system by blocking NMDA Receptors. The mechanism adderall sensitization reverse tolerance action of this drug is being closely studied to assess possible use for other illnesses which involve NMDA receptors. Adderall sensitization reverse tolerance NMDA receptors are glutamate class receptors and ion channel protein found in nerve cells, activating it causes positive ions to flow through cell membranes. This is a drug class for valium part of controlling memory function, and also synaptic plasticity. Calcium flux is one of the main reasons drug tolerances happens not the only mechanism, but a major one.
