Investigations of the association between benzodiazepine therapy and cognitive decline in elderly patients have yielded mixed findings. Stronger links have emerged from studies examining longer- rather than shorter-acting benzodiazepines, longer rather than shorter durations of use, or earlier rather than later exposure. Questions remain about causality and the impact of confounders on study interpretation.

Objective: To review the clinical pharmacology, efficacy, and safety of romosozumab, a humanized monoclonal antibody with a novel mechanism of action for monthly injection, and its place in the management of osteoporosis. Data Sources: PubMed, MEDLINE, and ClinicalTrials.gov searches (1966 to July 2020) were conducted using the keywords romosozumab and osteoporosis. Study Selection and Data Extraction: Published phase 2 and 3 clinical trials and 2 meta-analyses in patients with osteoporosis were included. Data Synthesis: Romosozumab increased bone mineral density (BMD) at the lumbar spine (12.1%-13.3%), femoral neck (2.2%-5.9%), and total hip (2.5%-6.9%) in patients with osteoporosis. After 12 months, romosozumab provided greater BMD gains at the lumbar spine and hip than teriparatide. However, teriparatide is likely to further increase BMD if continued for up to 24 months. In postmenopausal women at a high fracture risk, 1 year of romosozumab followed by 1 year of alendronate resulted in lower vertebral, nonvertebral, clinical, and hip fractures than alendronate alone for 2 years. Although absolute event rates were low, serious cardiovascular and cerebrovascular events were numerically higher in 2 clinical trials when compared with alendronate (2.5% vs 1.9%, respectively) and placebo (4.9% vs 2.5%, respectively). Relevance to Patient Care and Clinical Practice: This review discusses the place in therapy for romosozumab in osteoporosis management as a novel agent. Conclusions: Romosozumab offers an alternative for patients with a high risk of osteoporotic fractures. Clinicians should avoid romosozumab in patients with a history of myocardial infarction or stroke in the past 12 months.

Aclidinium bromide is a novel, inhaled, long-acting anticholinergic that, when administered at the FDA-approved dose, safely produces clinically and statistically significant bronchodilation and improves health status in patients with moderate to severe COPD. Long-term clinical trials assessing the efficacy and safety of aclidinium are warranted.
