Purpose:
Investigating the efficacy and safety of rupatadine (RUP) versus montelukast (MON) as adjuvant therapy for patients with rheumatoid arthritis (RA).
Methods:
From December 2018 to December 2019, 75 patients with active RA were enrolled in this randomized double-blind placebo-controlled study. The patients were randomized into three groups (n = 25 in each group); methotrexate (MTX) group which received MTX 15-25 mg/week plus placebo tablet once daily; MTX/RUP group which received MTX plus RUP 10 mg once daily; and MTX/MON group which received MTX plus MON 10 mg once daily. The treatment duration was 3 months. At baseline and 3 months after treatment, blood samples were collected for the biochemical analysis of high-sensitivity C-reactive protein (hs-CRP), interleukins 8 and 17 (IL-8, IL-17), E-selectin, and clusterin (CLU) levels. Clinical and functional assessments using Disease Activity Score-CRP (DAS28-CRP) and Multidimensional Health Assessment Questionnaire (MDHAQ) were performed.
Results:
Both RUP and MON produced clinical and functional improvements which were translated by significant improvements in DAS28-CRP score and MDHAQ. Rupatadine significantly reduced all measured parameters (P < 0.05) except for IL-17 and CLU. Montelukast significantly decreased all measured variables (P < 0.05) except for E-selectin. Interleukin-8 was positively correlated with IL-17 and CLU, while hs-CRP was positively correlated with E-selectin and body mass index (BMI). Both drugs were well tolerated; somnolence was the common side effect for RUP. No neuropsychiatric events were reported with MON.
Conclusion:
Rupatadine or montelukast may serve as a potential adjuvant therapy for patients with rheumatoid arthritis secondary to the preliminary evidence of efficacy and safety. ClinicalTrials.gov identifier NCT03770923, December 10, 2018.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
