IFIS is a clinical syndrome observed during cataract surgery reported in patients taking systemic alpha(1)AR antagonists. It has been most strongly linked to use of tamsulosin. Medication washout periods of up to 2 weeks and specific surgical procedures have been attempted to reduce risk of complications from alpha(1)AR antagonists in the setting of cataract surgery. Patients should be educated regarding potential risks of this drug class so that they can discuss them with their healthcare providers, specifically ophthalmologists, prior to cataract surgery.
Alvimopan, a peripherally acting mu-opioid receptor antagonist, is a novel agent for the treatment of postoperative ileus. It appears to decrease the duration of postoperative ileus and hospitalization by approximately one day, theoretically offsetting its acquisition costs. Unresolved long-term safety issues, a limited indication, and its restricted-access program are likely to hinder its widespread use in the surgical population.
IABP-associated thrombocytopenia occurred in 57.9% of this cohort. HIT was diagnosed in 2.8% and should be considered as a diagnosis if platelet counts do not stabilize or continue to fall after 3-4 days of counterpulsation. Increased use of antiplatelet therapy does not impact the degree of thrombocytopenia although the current practice of prompt IABP removal may offset this effect.
Silodosin was approved by the Food and Drug Administration in 2008. Long-term studies demonstrating improvement in clinically important outcomes of BPH have yet to be published. In addition, pharmacoeconomic analyses would assist in defining its current place in therapy. Until this information is available, silodosin may be best reserved as an alternative to other second- and third-generation alpha(1)-AR antagonists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
