Abstract

BASIS:

A significant proportion of our patients has described to have problems from tolerance to Dolquine, a new presentation of hydroxychloroquine recently marketed in Spain, compared to Plaquenil. The objective was to know the tolerability and the adverse effects of this new presentation.

PATIENTS AND METHOD:

A cross-sectional multicenter study on 133 patients treated with Dolquine was conducted.

RESULTS:

Of the 133 patients (87% women; average age [AA]: 32.9 [15.4] years) who received Dolquine during an average period of 6.7 (1.4) months, 32 patients (24%) described to have more problems with this drug in comparison with other antimalarial. The adverse effects experienced were: bitter taste (62.4%), difficulty in swallowing the tablet (13.5%), dyspepsia (9.8%), nausea (7.5%), vomiting (1.5%), pruritus (1.5%), diarrhea (0.7%), and instability feeling (0.7%). The presence of gastrointestinal adverse effects was not related to the consumption of gastroerosive drugs, gastric protectors, or a high number of drugs. The attrition rate was 9.8%. Conclusions. Dolquine induces lower tolerance and more gastrointestinal adverse effects than Plaquenil, pointing out its bitter taste and the difficulty in swallowing it. Despite this higher intolerance there was not an increase in the attition rate from the antimalarial treatment in comparison to other series.
