However, in the United States febuxostat is more expensive than
allopurinol. Also, a 2018 study found that although febuxostat was associated with similar rates of major cardiovascular events as
allopurinol, the rate of deaths from cardiovascular disease and all causes was slightly higher in febuxostat-treated patients.
Although disputed by some investigators, early observations suggested that patients with CKD were more likely to experience
allopurinol hypersensitivity, presumably owing to excessive
allopurinol or oxypurinol serum levels.
Research has suggested that both febuxostat and
allopurinol have similar efficacy.
Conclusion:
Allopurinol was found to be more effective than febuxostatin reducing the left ventricular mass and left ventricular hypertrophy independent of blood pressure.
"A strategy of
allopurinol dose escalation, which in current real-life practice is characterized by limited dose increases, is unlikely to improve the survival of patients with gout," the authors write.
The patient was diagnosed with allopurinol-induced DRESS syndrome in accordance with these clinical and histophatological findings, so the use of
allopurinol was stopped immediately.
* Should the dosage of
allopurinol be increased or should a non-xanthine oxidase inhibitor be initiated?
"I took the medicine for about 10 days (
allopurinol and Maxigesic Paracetamols) but then I noticed some lumps on my throat which were very painful," she pointed to an area under her jaw, just below her ear, to show the exact spot.
In a modified intention-to-treat analysis at a median of 32 and maximum of 85 months of follow-up, the rate was 10.8% in the febuxostat group and similar at 10.4% in the
allopurinol group.
Nonetheless, the groups with
allopurinol treatment (i.e.
These patients had been diagnosed with allopurinol-induced SCARs within the first 3 months of
allopurinol exposure.
The patients were then administered with 100 mg/day of
allopurinol for 2 years.
