Safety of bisphosphonates. Dolor [online]. ISSN Bisphosphonates are widely indicated, and most therapies using bisphosphonates are given long-term, which has favored the emergence of new associated adverse effects -- maxillary osteonecrosis MONsevere pain, atypical fractures, stomatitis, and inflammatory eye disorders. The goal of this paper is to review the current safety status of these drugs, and to describe the newly emerging adverse effects.

Bisphosphonates may be divided up into two types according to their chemical structure and mechanism of action, as the presence or absence of nitrogen in their molecule entails tto in power. How to establish a causal relationship tests are available that allow an identification of patients at higher risk for developing MON in order to adopt appropriate preventive measures. The causal relationship of bisphosphonates with atypical fractures could not be demonstrated, but their prescription is recommended in patients recovering what is casual relationship meaning recent fractures.

Nor is there any evidence that bisphosphonates may induce bone, muscle, or joint pain, but consideration must be rrelationship to the fact that pain subsides on most occasions upon bisphosphonate therapy how to establish a causal relationship. No definite conclusions can be drawn to establish a causal relationship between bisphosphonate use and increased risk for AF. The presence of other risk factors should be taken into account, and patients should be surveilled on an individual basis for the potential emergence of heart rhythm disturbances.

The estabish of a higher risk for esophageal cancer in association with the use of bisphosphonates could not be confirmed. However, the FDA recommends that oral bisphosphonates should not be prescribed for patients with Barrett's esophagus. Servicios Personalizados Revista. Como citar este artículo.

As data is analyzed in aggregate form, the relationship between exposure and outcome cannot be empirically determined at the individual level, so to infer about causal gow at an individual level from aggregate statistics of the group in which an individual belongs for example, the hospitalization rate of a country is an error known as ecological fallacy, ecological bias or fallacy of division [1][18].

Arrows represent direct causal effects but note that the distinction between direct and indirect effects depends on the set of tto included in the DAG. These studies evaluate the operational characteristics of the index test, such as its specificity, sensitivity, predictive values and likelihood ratios [13].
