A growing body of evidence provides a rationale for the use of collagen hydrolysate for patients with OA. It is hoped that ongoing and future research will clarify how collagen hydrolysate provides its clinical effects and determine which populations are most appropriate for treatment with this supplement.

Tanezumab provides efficacious treatment of knee or hip OA and may have therapeutic utility in patients with OA who experience inadequate analgesia with nonsteroidal antiinflammatory drugs.

Methotrexate (MTX) remains the cornerstone therapy for patients with rheumatoid arthritis (RA), with well-established safety and efficacy profiles and support in international guidelines. Clinical and radiologic results indicate benefits of MTX monotherapy and combination with other agents, yet patients may not receive optimal dosing, duration, or route of administration to maximize their response to this drug. This review highlights best practices for MTX use in RA patients. First, to improve the response to oral MTX, a high initial dose should be administered followed by rapid titration. Importantly, this approach does not appear to compromise safety or tolerability for patients. Treatment with oral MTX, with appropriate dose titration, then should be continued for at least 6 months (as long as the patient experiences some response to treatment within 3 months) to achieve an accurate assessment of treatment efficacy. If oral MTX treatment fails due to intolerability or inadequate response, the patient may be “rescued” by switching to subcutaneous delivery of MTX. Consideration should also be given to starting with subcutaneous MTX given its favorable bioavailability and pharmacodynamic profile over oral delivery. Either initiation of subcutaneous MTX therapy or switching from oral to subcutaneous administration improves persistence with treatment. Upon transition from oral to subcutaneous delivery, MTX dosage should be maintained, rather than increased, and titration should be performed as needed. Similarly, if another RA treatment is necessary to control the disease, the MTX dosage and route of administration should be maintained, with titration as needed.

OBJECTIVES:We performed two 24-week double-blind trials (REDUCE-1 and -2 (Registration Endoscopic Studies to Determine Ulcer Formation of HZT-501 Compared with Ibuprofen: Efficacy and Safety Studies)) to assess whether double-dose famotidine given in a single-tablet combination with ibuprofen (HZT-501) significantly reduces gastric and duodenal ulcers as compared with ibuprofen.METHODS:Patients (40–80 years) requiring daily non-steroidal anti-inflammatory drugs (NSAIDs) for ≥6 months with no prior ulcer complications, negative H. pylori stool test, and baseline endoscopy showing no ulcers and <5 erosions were randomly assigned in a 2:1 ratio to HZT-501 or identical-appearing ibuprofen 800 mg tablets thrice daily. Study endoscopies were done at 8, 16, and 24 weeks. After unblinding and initial analyses, 12 patients were found to be misclassified as having gastric ulcers based on the adjudication of endoscopy reports, and analyses were re-run.RESULTS:In REDUCE-1, the primary end point analysis of gastric ulcers at 24 weeks with HZT-501 vs. ibuprofen was 12.7% vs. 22.9% (P=0.0044) in the post-adjudication analysis. In REDUCE-2, the primary end point analysis of upper gastrointestinal (GI) ulcers was 13.0% vs. 20.5% (P=0.0587) in the post-adjudication analysis. Prespecified pooled analyses showed significantly fewer gastric (12.5% vs. 20.7%) and duodenal ulcers (1.1% vs. 5.1%) with HZT-501 vs. ibuprofen. Proportional hazards analysis of multiple potential risk factors showed the risk ratio of upper GI ulcers with HZT-501 vs. ibuprofen was 0.46, 95% confidence interval was 0.34–0.61.CONCLUSIONS:Combined results of the REDUCE studies indicate that double-dose famotidine plus ibuprofen, given as a combination tablet, decreases endoscopic upper GI ulcers as compared with ibuprofen alone.
