Pramipexole Mechanism of Action Action Pathway
smpdb.ca/view/SMP0126459Drug actionPramipexole is indicated for the management of Parkinson's disease and symptomatic treatment of moderate to severe primary Restless Legs Syndrome (RLS). Pramipexole likely restores balance to the dopaminergic system, controlling the symp...

smpdb.ca/view/SMP0000604Drug metabolismCyclophosphamide is an alkylating agent used in the treatment of certain cancers. Following absorption, cyclophosphamide is converted into 4-hydroxyphosphamide by a variety of cytochrome P450 isozymes in the liver. 4-Hydroxyphosphamide i...
Enzymes: Glutathione S-transferase Mu 1Aripiprazole Dopamine agonist Action Pathway
smpdb.ca/view/SMP0126454Drug actionAripiprazole is an atypical antipsychotic used in the treatment of a wide variety of mood and psychotic disorders, such as schizophrenia, bipolar I, major depressive disorder, irritability associated with autism, and Tourette's syndrome....
