'''Antigout agents''' — Antigout; Xanthine oxidase inhibitors (allopurinol, febuxostat), anti-inflammatory antimitotic (colchicine), uricosuric (probenecid).

== Identification ==
* '''Therapeutic class:''' Antigout.
* '''Pharmacologic class:''' Xanthine oxidase inhibitors (allopurinol, febuxostat), anti-inflammatory antimitotic (colchicine), uricosuric (probenecid).

== Pharmacology ==
* '''Mechanism of action:''' Allopurinol and febuxostat reduce uric acid production; colchicine reduces inflammatory response to urate crystals; probenecid increases uric acid excretion.
* '''Onset / peak / duration:''' Allopurinol lowers urate over days to weeks; colchicine acts within hours on acute flares.
* '''Half-life / therapeutic level:''' Varies; no routine level.

== Clinical use ==
* '''Indications:''' Chronic gout and hyperuricemia prevention (allopurinol, febuxostat, probenecid), acute gout flares and prophylaxis (colchicine), tumor lysis prevention (allopurinol).
* '''Usual dose, route, frequency:''' Allopurinol PO daily; colchicine PO for flares and low-dose prophylaxis.
* '''Maximum dose / adjustments:''' Reduce allopurinol and colchicine in renal impairment; do not start urate-lowering therapy during an acute flare (can worsen it).

== Safety ==
* '''Contraindications:''' Colchicine with strong CYP3A4 or P-gp inhibitors in renal or hepatic impairment (toxicity); hypersensitivity.
* '''Black box warning:''' None.
* '''Interactions:''' Allopurinol with azathioprine and mercaptopurine (severe toxicity), warfarin; colchicine with clarithromycin and other CYP3A4 or P-gp inhibitors (fatal toxicity), statins; probenecid with many renally cleared drugs.
* '''Pregnancy / lactation:''' Use only if clearly needed.
* '''High-alert:''' No.

== Adverse effects ==
* '''Common side effects:''' Allopurinol rash and GI upset; colchicine diarrhea, nausea, cramping.
* '''Serious effects to report:''' Allopurinol hypersensitivity and Stevens-Johnson syndrome (linked to HLA-B*5801), colchicine toxicity (severe GI symptoms, myopathy, marrow suppression).
* '''Antidote / reversal:''' Supportive care.

== Nursing process ==
* '''Assessment before administration:''' Renal and hepatic function, uric acid, current flare status, interacting drugs.
* '''Interventions during therapy:''' Do not start allopurinol during an acute attack; encourage fluids; watch for rash.
* '''Monitor:''' Uric acid, renal function, CBC (colchicine), skin.
* '''Evaluation / expected outcome:''' Fewer gout flares and lower uric acid.

== Patient teaching ==
* '''Patient teaching:''' Allopurinol is preventive, not for acute pain; report any rash; drink plenty of fluids; do not exceed colchicine dosing.
* '''Notify provider if:''' Rash, severe diarrhea or muscle pain, fever, easy bruising.
* '''Administration tips:''' Take allopurinol after meals with fluids; follow colchicine dose limits exactly.
