Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Comparison of TTS-fentanyl with sustained-release oral morphine in the treatment of patients not using opioids for mild-to-moderate pain.
This randomised, multicentre, direct open comparative trial evaluated the efficacy, treatment convenience, tolerability and safety aspects of transdermal therapeutic system (TTS)-fentanyl and sustained-release oral morphine (SRM) in both opioid-naïve patients with moderate-to-severe cancer-related pain and in patients who had already been using opioids for mild-to-moderate pain. The two treatment groups were run in parallel. Special attention was paid to constipation, nausea/vomiting, drowsiness and respiratory depression. ⋯ These data indicate that TTS-fentanyl, when used as an opioid of first choice in the treatment of cancer-related pain, is as effective as, but better tolerated than, SRM, including in opioid-naïve patients.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A comparison of the therapeutic efficacy and tolerability of etoricoxib and diclofenac in patients with osteoarthritis.
To evaluate and compare the efficacy and tolerability of etoricoxib and diclofenac in patients with osteoarthritis of the knee or hip. ⋯ Etoricoxib is clinically effective in the therapy of osteoarthritis providing a magnitude of effect comparable to that of the maximum recommended daily dose of diclofenac. The onset of clinical benefit with etoricoxib on day one is more rapid than that of diclofenac. Both drugs were generally well tolerated.

This commentary article provides an overview of recent clinical research trials involving anastrozole and its evolving role in the management of breast cancer. Anti-aromatase agents inhibit the cytochrome P-450 component of the aromatase enzyme complex responsible for the final step of estrogen biosynthesis in peripheral tissues which are the main source of estrogen in postmenopausal women. Anastrozole is a third-generation non-steroidal aromatase inhibitor. ⋯ Furthermore, the preliminary results of the Arimidex, Tamoxifen, Alone and in Combination (ATAC) study have shown that adjuvant anastrozole is superior to tamoxifen in terms of disease-free survival (DFS), non-musculoskeletal adverse effects and prevention of contralateral breast cancer in postmenopausal women with early, ER-positive breast cancer. Although longer follow-up is required to assess the long-term effects of anastrozole on bone mineral density, cognitive function and overall survival, the drug has been recently approved for adjuvant use in postmenopausal women with early, ER-positive breast cancer who are unable to tolerate tamoxifen or at an increased risk of developing thromboembolism or endometrial cancer. The potential role of anastrozole in the neoadjuvant setting, the management of DCIS, premenopausal breast cancer and breast cancer prevention is currently being investigated.
