  • Exposure Routes: Oral. Readily absorbed in a biphasic manner when orally administered (tablets) to children diagnosed with ADHD and to healthy adults. In children and adults males, after administration of a single oral dose of Ritalin LA and Ritalin given in two doses 4 hours apart, peak plasma concentration is reached approximately 2 hours for the first phase and 5-6 hours for the second phase. The absolute oral bioavailability of methylphenidate in children was 22±8% for d-methylphenidate and 5±3% for l-methylphenidate. These low values suggest that methylphenidate is highly metabolized presystemically. Source: Toxin and Toxin Target Database (T3DB)

  • Health Effects: Using large amounts of these drugs can result in a condition known as amphetamine psychosis -- which can result in auditory, visual and tactile hallucinations, intense paranoia, irrational thoughts and beliefs, delusions, and mental confusion. Source: Toxin and Toxin Target Database (T3DB)
  • Toxicity Summary: IDENTIFICATION AND USE: Methylphenidate Hydrochloride is a psychostimulant used to treat different behavioral disorders. Indications: Used to treat narcolepsy and hyperkinetic states in children (as an adjunct to psychological, educational and social measures) for amphetamine, dextroamphetamine and ethylphenidate. It is misused for performance enhancement and relief of fatigue. Abuse either orally or by injection is extremely common. HUMAN EXPOSURE AND TOXICITY: Main risks include: Acute central nervous system (CNS) stimulation, cardiotoxicity causing tachycardia, arrhythmias, hypertension and cardiovascular collapse. High risk of dependency and abuse. Cardiovascular effects include: palpitation, chest pain, tachycardia, arrhythmias and hypertension; cardiovascular collapse can occur in severe poisoning. Myocardial ischemia, infarction and ventricular dysfunction are described. CNS effects include: stimulation of CNS, tremor, restlessness, agitation, insomnia, increased motor activity, headache, convulsions, coma and hyperreflexia. Stroke and cerebral vasculitis have been observed. Gastrointestinal effects include: vomiting, diarrhea and cramps. Genitourinary effects include: incre Source: Hazardous Substances Data Bank (HSDB)
  • Toxicity Summary: The first step in a medication overdose is to immediately contact a poison control center for the appropriate management steps. Doses that exceed 60 mg of the immediate-release formulation or 120 mg of the extended-release formulation can be considered toxic. If the overdosed quantity is unknown, the patient should be assessed for signs and symptoms such as tremors, hyperreflexia, convulsions, euphoria, confusion, hallucinations, delirium, flushing, and fever, in addition to the common adverse effects mentioned above. Supportive care with supplemental oxygen, intravenous fluids, and external cooling methods is the mainstay of treatment. Multiple studies have shown that benzodiazepines are an option, especially if dystonia, agitation, or convulsions are present. Source: StatPearls
  • 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. Alteration of serotonergic pathways via changes in dopamine transport may result. Source: Toxin and Toxin Target Database (T3DB)
  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for methylphenidate(SRC), using a log Kow of 0.20(1) and a regression-derived equation(2). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1600(SRC), determined from a structure estimation method(2), indicates that methylphenidate is expected to have low mobility in soil(SRC). The pKa of methylphenidate is 8.9(3), indicating that this compound will exist partially in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of the neutral species of methylphenidate from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.4X10-9 atm-cu m/mole(SRC), using a fragment constant estimation method(5). Methylphenidate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 5.9X10-5 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). Biodegradation data in soil were not available(SRC, 2015). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1600(SRC), determined from a structure estimation method(2), indicates that methylphenidate is expected to adsorb to suspended solids and sediment(SRC). Volatilization of the neutral species from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 4.4X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). A pKa of 8.9(5) indicates methylphenidate will exist partially in the cation form at pH values of 5 to 9 and, therefore, volatilization from water surfaces is not expected to be an important fate process(SRC). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow of 0.20(7) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Base-catalyzed second-order hydrolysis rate constant half-lives of 23 and 2.3 years at pH values of 7 and 8, respectively(2), suggest that hydrolysis may be a slow environmental fate process. Biodegradation data in water were not available(SRC, 2015). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), methylphenidate, which has an estimated vapor pressure of 5.9X10-5 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase methylphenidate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 1 hr(SRC), calculated from its rate constant of 1.1X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase methylphenidate may be removed from the air by wet and dry deposition(SRC). Methylphenidate contains chromophores that absorb at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)

  • Uses: Schedule II Controlled Substance: (A) The drug or other substance has a high potential for abuse; (B) The drug or other substance has a currently accepted medical use in treatment in the United States or a currently accepted medical use with severe restrictions; and (C) Abuse of the drug or other substances may lead to severe psychological or physical dependence.
