Possible Interaction: Dextroamphetamine and Methylphenidate

Research Papers that Mention the Interaction

The results of this experiment are concordant with previous studies and suggest that the behavioral effects of oral methylphenidate and d-amphetamine overlap extensively and that the discriminative-stimulus effects of methylphenidate and d-amphetamine are symmetrical.

Both methylphenidate and d-amphetamine produced dose-dependent increases in stimulant-like subject ratings (e.g. Active, Alert, or Energetic and High), but the effects of these drugs were not isomorphic.
The intermediate dose of methylphenidate and d-amphetamine increased responding significantly above placebo levels.

These results further demonstrate that the acute behavioral effects of d-amphetamine and methylphenidate overlap extensively in humans, which is concordant with preclinical studies.

The occurrence of abnormal movements or perserverative/compulsive behaviors was noted in 34 (76%) of a group of 45 hyperactive boys during a double-blind crossover treatment trial of methylphenidate and dextroamphetamine given in a wide range of doses.

Whereas PCP potentiated the locomotor activity induced by d-amphetamine in both reserpine- and vehicle-pretreated subjects, methylphenidate marginally antagonized d-amphetamine-induced stereotypy in reserpine-pretreated subjects.

If methylphenidate acts by inhibiting the dopamine uptake it should antagonize the skeotypied behaviour produced by (+)-amphetamine m merpinized rats, in which methylphenidate itself has activity, but not influence the stereotypies by apomorphine which acts directly on the dopamine receptors (Emst, 1965).

She argues that: dexamphetamine prescription rates have markedly decreased since the availability of slow release methylphenidate capsules , which are much more difficult to divert.

Response to methylphenidate was associated with increases in inattention on a continuous performance task after dextroamphetamine challenge.

Methylphenidate and dextroamphetamine caused marked aggravation of his motor and vocal tics.

These findings suggest that early exposure do methylphenidate might increase the risk for subsequent D-amphetamine abuse.
