Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of the clinical efficacy and safety of salmeterol/fluticasone propionate versus current care in the management of persistent asthma in Korea.
In the Asia-Pacific region there is a general preference for prescribing oral over inhaled medications for the treatment of asthma. This study compared inhaled salmeterol/fluticasone propionate therapy (SFC) with physician-determined current care (CC) in the management of persistent asthma in Korea. ⋯ Adult patients with a documented history of reversibility in FEV(1) (>or= 12%) or PEF (>or= 15%), were randomised in a 2:1 ratio to unblinded treatment with SFC (50/250 microg bd or 50/500 microg bd) via Diskus (N = 284) or CC (N = 140) for 52 weeks. Morning peak expiratory flow (PEF) (primary endpoint), exacerbations, asthma symptoms and patient-reported outcome measures were recorded.

Randomized Controlled Trial Multicenter Study Comparative Study
Fixed-ratio combination oxycodone/naloxone compared with oxycodone alone for the relief of opioid-induced constipation in moderate-to-severe noncancer pain.
Opioid therapy is frequently associated with treatment-limiting constipation. Naloxone is an opioid antagonist with low oral systemic bioavailability. This Phase III clinical trial assessed the safety and efficacy of an oral fixed-ratio combination of oxycodone prolonged-release (PR) and naloxone PR compared with oxycodone PR in relieving opioid-induced constipation. ⋯ This double-blind, multicenter trial was conducted in specialist and primary care centers in four European countries in an out-patients setting. The study included 322 adult patients with moderate-to-severe, noncancer pain requiring opioid therapy in a range of >or=20 mg/day and

Randomized Controlled Trial Multicenter Study Comparative Study
Analgesic efficacy and tolerability of flupirtine vs. tramadol in patients with subacute low back pain: a double-blind multicentre trial*.
To assess the efficacy and tolerability of flupirtine in comparison with tramadol for the treatment of moderate to severe subacute low back pain (LBP). ⋯ Flupirtine 100 mg three times daily was associated with a reduction in pain and improvements in functional capacity equivalent to that observed with tramadol 50 mg three times daily, and was better tolerated, when administered to patients with subacute back pain for one week. The limitations of this study were the lack of a placebo control and the short (7-day) duration of the study.

Randomized Controlled Trial Multicenter Study
Dose-ranging study of fluticasone furoate nasal spray for Japanese patients with perennial allergic rhinitis*.
This study was designed to evaluate the efficacy and safety of fluticasone furoate nasal spray (FFNS), a novel enhanced-affinity intranasal corticosteroid, in Japanese patients with perennial allergic rhinitis (PAR), and to determine the optimal dose. ⋯ Both FFNS 110 microg and 220 microg od were effective in alleviating nasal symptoms in Japanese patients with PAR over the 2-week duration of this study. FFNS 110 microg od was selected as the optimal dose for further evaluation in phase III clinical trials.

Multicenter Study
Frequency of self-monitoring of blood glucose in patients with type 2 diabetes: association with hypoglycaemic events.
The objective of this study is to describe current self-monitoring of blood glucose (SMBG) practice for patients with type 2 diabetes by treatment type and adherence with healthcare professional advice concerning SMBG. In addition, the study aims to investigate the association of SMBG and self-reported episodes of low blood glucose. ⋯ Among patients with type 2 diabetes, those treated with insulin used SMBG at a greater frequency than those not treated with insulin. Increased frequency of testing was associated with increased frequency of self-reported episodes of low blood glucose, even among patients not taking insulin or sulfonylureas. This raises the possibility that episodes of hypoglycaemia may not be accurately identified, leading to unnecessary fear, or conversely that treatment is not being adjusted to avoid such morbidity. Although further work is needed to explore this association in a representative, prospective cohort of patients, possible explanations for reports of low-blood glucose should be discussed with patients using SMBG more frequently to ensure they are able to accurately identify episodes of hypoglycaemia.
