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.

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 review of paroxetine is based on Medline and PsycLit searches and a manual search of the available research literature. It aims to cover the pharmacology of this frequently prescribed SSRI antidepressant in terms of its indications, efficacy and adverse effects. Overall, paroxetine is a well-tolerated and safe first-line SSRI antidepressant with anxiolytic qualities. ⋯ The antidepressant has some advantages over earlier tricyclic medication in terms of a lack of cardiovascular side-effects and relative safety in overdose. Cessation of use, however, is associated with withdrawal or discontinuation symptoms and patients should be counselled as to how these might be avoided. A 3- or 4-week graded withdrawal regimen, perhaps with concomitant fluoxetine to cover serotonergic discontinuation symptoms, may be advisable.

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.

Clinical Trial
An open-label study of a second course of hylan G-F 20 for the treatment of pain associated with knee osteoarthritis.
To evaluate the efficacy and tolerability of a second course of hylan G-F 20 for the treatment of osteoarthritic knee pain in patients who experienced a clinical benefit with an initial course of therapy. ⋯ A second course of hylan G-F 20 therapy is an appropriate therapy for the treatment of OA knee pain in patients who had a previous favorable clinical response. For continued relief of osteoarthritis knee pain, this study supports repeat use of hylan G-F 20 in these patients.
