Abstract

Objectives:

To determine preference, satisfaction, usability and local tolerability by patients, physicians and study nurses of two subcutaneously administered methotrexate (MTX) formulations of different concentrations.

Methods:

This was an open-label, comparative, within-patient controlled, multicentre study of 132 patients with rheumatoid arthritis (RA). MTX treatment consisted of 20 mg/week administered as a medium-concentration formulation (MC) (2.0 ml of 10 mg/ml solution in prefilled syringe; separate needle) compared to a novel high-concentration formulation (HC) (0.4 ml of 50 mg/ml in prefilled syringe; pre-attached needle). Each treatment was given for three weeks. Questionnaires and visual analogue scales were used to measure outcomes.

Results:

At the end of the study, 93% of the patients preferred HC over MC as further treatment. Overall assessment of HC was “good” or “very good” in 90.6% vs 34.4% in MC-treated patients. Physician’s and patients global assessment of syringe usability showed highly statistically significant differences (P < 0.0001) in favour of HC. Overall assessment by study nurses’ and investigators’ was “good” (18.8%) or “very good” (81.2%) for HC and “good” in 31.3% or “very good” in 12.5% for MC, and no preference in 50%. Local tolerability improved slightly also with HC.

Conclusions:

The total smaller volume of administered drug and the improved usability of a pre-attached needle in combination with a smaller prefilled syringe resulted in preference of the patients of HC over MC. The slightly improved local tolerability may also have added to this preference. This assessment was confirmed by similar assessments made by healthcare professionals.

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
