Dược Lực Học :
Methylphenidate is a central nervous system stimulant used most commonly in the treatment of attention-deficit disorders in children and for narcolepsy.
Cơ Chế Tác Dụng :
Dexmethylphenidate is the dextrorotary form of methylphenidate. It is a norepinephrine-dopamine reuptake inhibitor (NDRI) and thus a psychostimulant. It is used for treatment of Attention Deficit Hyperactivity Disorder (ADHD).
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.
Dược Động Học :
▧ Absorption :
11-52%
▧ Protein binding :
30%
▧ Metabolism :
epatic, methylphenidate is metabolized primarily by de-esterification to ritalinic acid (α-phenyl-2-piperidine acetic acid, PPAA), which has little to no pharmacologic activity.
▧ Route of Elimination :
Renal
▧ Half Life :
2-4 hours
Độc Tính :
Insomnia, dizziness, nausea, stomach pain, euphoria, headache, anxiety, anorexia, and weight loss are common side effects.
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. LD50=190mg/kg (orally in mice)
Chỉ Định :
Dexmethylphenidate is used as a treatment for ADHD, ideally in conjunction with psychological, educational, behavioral or other forms of treatment.
