1. Competitively inhibits Xanthine oxidase
2. purines lost as Xanthine and Hypoxanthine (never cinverted to uric acid)
(can also block purine synthesis)

Front
What is the active metabolite of Allopurinol?
Back
Yes and no. Both the parent and metabolite are active.
Front
Is probenecid a prodrug?
Back
Aromatic hydroxylation product of Sulfinpyrazone (Parahydroxy metabolite)
Front
What is this?
Back
Probenecid Glycine Conjugate (metabolite)
Front
What is this?
Back
1. When metabolized by aromatic hydroxylation (parahydroxy metabolite): URTA1 inhibitor
2. When metabolized by sulfoxide reduction: COX inhibition in platelets
Front
Sulfinpyrazone MOA
Back
nope
Front
Is Febuxostat a prodrug?
Back
Alloxanthine
Front
What is this?
Back
1. inhibits microtubule formation
2. inhibit mitosis
or
1. inhibit lactic acid production
2. increases pH* and solubalizes uric acid
Front
Colchicine MOA
Back
Yes and No. Both the parent and metabolite are active. (The metabolite has a longer half life so it is more active than the parent)
