Methylphenidate (MPH)
Mechanism of Action:
Non-competitively, Methylphenidate blocks the reuptake dopamine/noradrenaline into terminals by blocking dopamine transporter and noradrenalinetransporter (NAT), increasing dopamine levels in the synaptic cortex.
An l-isomer as well as a d.isomer are available for Amphetamine.
The active isomer is the d-isomer.
Mechanisms of Action :
1. Competing with noradrenaline and dopamine at NAT, competitive inhibitor at DAT
2. VMAT
Competitive inhibitor3. Reversal of DAT.
