Though the mechanism of action of cocaine is not fully understood, it is thought to bind to and block the dopamine transporter protein (DAT). Blocking the action of this protein increases the concentration of dopamine in the synaptic cleft, thereby producing the characteristic effects of cocaine (such as stimulation and euphoria). Cocaine also affects serotonin receptors, sigma receptors, and sodium channels, though these actions play less of a role in its pharmacology.
Amphetamine salts and methylphenidate are both stimulant medications used to treat conditions like ADHD. However, they have different chemical structures and mechanisms of action in the brain. Amphetamine salts work by increasing the levels of dopamine and norepinephrine in the brain, while methylphenidate primarily increases dopamine levels. This difference in mechanism can result in varying effects on individuals, such as differences in side effects and duration of action.

Methylphenidate and Adderall are both medications used to treat ADHD, but they work in different ways. Methylphenidate increases the levels of dopamine and norepinephrine in the brain by blocking their reuptake, while Adderall increases these levels by promoting their release and blocking their reuptake.
Methylphenidate and amphetamine are both stimulant medications used to treat conditions like ADHD. However, they have different mechanisms of action and effects. Methylphenidate works by increasing levels of dopamine and norepinephrine in the brain, while amphetamine works by increasing the release of these neurotransmitters. Methylphenidate is shorter-acting and tends to have a more gradual onset of action, while amphetamine is longer-acting and has a quicker onset. Additionally, some individuals may respond better to one medication over the other due to differences in how their bodies metabolize the drugs.

Amphetamines and methylphenidate are both stimulant medications used to treat conditions like ADHD. Amphetamines work by increasing the release of neurotransmitters like dopamine and norepinephrine, while methylphenidate works by blocking their reuptake. Amphetamines tend to have a more potent and immediate effect, while methylphenidate is considered to have a more gradual and sustained effect. Additionally, amphetamines have a higher potential for abuse and dependence compared to methylphenidate.
