Dotinurad is a selective urate reabsorption inhibitor (URAT1 inhibitor) used for lowering elevated serum uric acid levels.
About Dotinurad
Indications of Dotinurad
Dotinurad is a selective urate reabsorption inhibitor (URAT1 inhibitor) used for lowering elevated serum uric acid levels. Its evidence-based uses include:
- Established/labeled use: Treatment of hyperuricemia associated with gout, to reduce serum uric acid and decrease the frequency of gouty arthritis flares.
- Established/labeled use: Long-term management of chronic gout, including tophaceous gout, as part of urate-lowering therapy.
- Guideline-supported use: As an alternative urate-lowering agent in patients who are intolerant of, or have an inadequate response to, xanthine oxidase inhibitors (e.g., allopurinol, febuxostat), used either as monotherapy or in combination with a xanthine oxidase inhibitor.
Dotinurad is not indicated for treating acute gout flares themselves; it is used for chronic urate-lowering therapy and should not be started during an acute attack (see Precautions and Warnings).
Dosage & Administration of Dotinurad
Dotinurad is administered orally, once daily, with the dose individualized and titrated according to serum uric acid response.
| Indication | Dosing |
|---|---|
| Hyperuricemia with gout (adults) | Start at 0.5 mg once daily. If tolerated and serum uric acid remains above target, increase to 1 mg once daily after approximately 2 weeks, then to 2 mg once daily after approximately 6 weeks, based on physician assessment and uric acid monitoring. Usual maintenance dose is 2 mg once daily; maximum recommended dose is 4 mg once daily. |
| Pediatric use | Safety and efficacy have not been established in children; not recommended (see Use in Special Populations). |
| Renal impairment | Use with caution; efficacy may be reduced with worsening renal function, and use is contraindicated in severe renal impairment or dialysis-dependent patients (see Contraindications). |
Tablets of Dotinurad may be taken with or without food, at approximately the same time each day, to help maintain consistent uric acid control. Do not start Dotinurad during an acute gout attack; if a flare occurs while already on treatment, therapy is generally continued alongside appropriate anti-inflammatory treatment of the flare, under physician guidance.
Side Effects of Dotinurad
The following adverse effects have been reported with Dotinurad:
| Frequency | Effects |
|---|---|
| Common (approximately 1-5%) | Gouty arthritis flare (especially during dose initiation/titration), limb/joint discomfort |
| Uncommon (<1%) | Loose stools/diarrhea, elevated liver enzymes (transaminases), joint pain, renal/urinary stones (urolithiasis), increased blood creatinine, albuminuria/proteinuria |
Patients should seek prompt medical attention for signs of severe hypersensitivity, significant flank pain or blood in the urine (possible urolithiasis), or jaundice while taking Dotinurad.
Contraindications of Dotinurad
Dotinurad is contraindicated in:
- Patients with known hypersensitivity to Dotinurad or any component of the formulation.
- Patients with severe renal impairment, including those on dialysis, in whom Dotinurad is expected to be ineffective and may increase the risk of adverse renal effects.
Frequently Asked Questions about Dotinurad
What is Dotinurad used for?
Dotinurad is used to lower high uric acid levels (hyperuricemia) in patients with gout, helping to reduce the frequency of painful gout flares over the long term.
How should I take Dotinurad?
Dotinurad is taken orally, once daily, with or without food, at a dose determined and adjusted by your physician, usually starting low and increasing gradually. Do not change your dose without consulting your doctor.
Can Dotinurad be taken during an acute gout attack?
Dotinurad should not be started during an active gout flare, as urate-lowering medicines can temporarily worsen an acute attack. If you are already taking Dotinurad and experience a flare, your doctor will usually continue your treatment while managing the flare separately.
Who should not take Dotinurad?
Dotinurad should not be used by anyone with a known allergy to it, or by patients with severe kidney impairment or those on dialysis, since it is not expected to work well and may pose additional risks in these situations.
Is Dotinurad safe during pregnancy or breastfeeding?
Information on Dotinurad in pregnancy is limited, so it should only be used if your doctor determines the benefits outweigh the potential risks to the baby. Dotinurad may pass into breast milk, so discuss breastfeeding plans with your physician before use.
What side effects can Dotinurad cause?
Common effects of Dotinurad include gout flares (especially early in treatment) and joint or limb discomfort. Less commonly, it can cause diarrhea, elevated liver enzymes, kidney stones, or increased creatinine. Drink plenty of fluids and report any unusual symptoms, such as flank pain or blood in urine, to your doctor promptly.
