概要
Dexmethylphenidate Hydrochloride is a synthetic sympathomimetic amine with CNS stimulating properties. Dexmethylphenidate hydrochloride acts by facilitating the release of catecholamines, particularly noradrenaline and dopamine, from nerve terminals in the brain and inhibits their uptake. This leads to an increase in motor activity, causes euphoria, mental alertness and excitement and suppresses appetite. This drug causes dependence and may cause an increase in heart rate and blood pressure. It is used in the treatment of attention deficit hyperactivity disorder. It may also be used in the treatment of fatigue and other nervous system effects seen with chemotherapy.

Toxicity Summary
Methylphenidate blocks dopamine uptake in central adrenergic neurons by blocking dopamine transport or carrier proteins. Methylphenidate acts at the brain stem arousal system and the cerebral cortex and causes increased sympathomimetic activity in the central nervous system. Methylphenidate is a catecholamine reuptake inhibitor that indirectly increases catecholaminergic neurotransmission by inhibiting the dopamine transporter (DAT) and norepinephrine transporter (NET), which are responsible for clearing catecholamines from the synapse, particularly in the striatum and meso-limbic system.
Signs and Symptoms
Symptoms of overdose include vomiting, agitation, tremors, hyperreflexia, muscle twitching, convulsions (may be followed by coma), euphoria, confusion, hallucinations, delirium, sweating, flushing, headache, hyperpyrexia, tachycardia, palpitations, cardiac arrhythmias, hypertension, mydriasis, and dryness of mucous membranes.
Carcinogen ClassificationNo indication of carcinogenicity to humans (not listed by IARC).

薬理情報
Metabolism/Metabolitesepatic, methylphenidate is metabolized primarily by de-esterification to ritalinic acid (α-phenyl-2-piperidine acetic acid, PPAA), which has little to no pharmacologic activity.

FDA Pharmacological Classification
DEXMETHYLPHENIDATE HYDROCHLORIDE
Central Nervous System Stimulation [PE]; Central Nervous System Stimulant [EPC]
MeSH Pharmacological Classification
A loosely defined group of drugs that tend to increase behavioral alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here.
Drugs that block the transport of DOPAMINE into axon terminals or into storage vesicles within terminals. Most of the ADRENERGIC UPTAKE INHIBITORS also inhibit dopamine uptake.
用途と製造
UsesDexmethylphenidate is used as a treatment for ADHD, ideally in conjunction with psychological, educational, behavioral or other forms of treatment.
