BACKGROUND High-risk medication exposure in the elderly is common and associated with increased mortality, hospitalizations, and emergency department (ED) visits. Skeletal muscle relaxants and antihistamines are high-risk medications commonly prescribed in elderly patients. The objective of this study was to determine the association between skeletal muscle relaxants or antihistamines and morta...

BACKGROUND Muscle relaxants induce vascular smooth muscle relaxation by inducing synthesis of the prostaglandins that influence vasomotor tone. However, the effects of muscle relaxants on endothelial cells and tissues following injury by reactive oxygen species (ROS) are unclear. We tested the effects of the muscle relaxants vecuronium and rocuronium on impaired acetylcholine (ACh)-induced rela...

In summary, it appears from this and other studies that trimetaphan has the potential for producing neuromuscular blockade when used in large doses or when combined with other muscle relaxants. The mode of action appears to be principally that of non-depolarizing neuromuscular blockade. Sodium nitroprusside, on the other hand, even in doses beyond these accepted clinically, does not affect neur...

1 Muscle weakness is a feature of many illnesses but the present discussion will be confined mainly to conditions in which it is a manifestation of defects in the anterior horn cells, the motor nerves, the neuromuscular junction, or the muscle itself. The pathogenesis of these disorders is often ill-understood and more than one component of the neuromuscular system may be involved. Moreover, kn...

Temporomandibular dysfunction is a benign pathology, with polymorphic expression and subject to multiple factors that participate in its etiology, which makes the diagnosis of certainty difficult. A wide range therapeutic options are available, including splints, physical therapy, pharmacotherapy (analgesics, muscle relaxants, anxiolytics, antidepressants, etc.)
