Direct oral anticoagulants (DOACs) such as dabigatran, rivaroxaban, and apixaban have significantly fewer drug-drug interactions (DDIs) compared with warfarin. However, there are notable DDIs with potent CYP3A4 and P-glycoprotein (p-gp) inhibitors with DOAC, which clinicians should consider requiring dose adjustments and monitoring for their older patients.
Each of the DOACs is a substrate for p-glycoprotein (p-gp), an efflux transporter located in the intestinal mucosa, and therefore all DOACs ...
Cannabis-derived products are now available for use with therapeutic intentions in Australia and New Zealand. By far the most common reason for their proposed use is chronic pain. More than 90% of Special Access Scheme – Category B approvals for cannabis products have been for chronic pain of various types. Cannabidiol-only formulations have not been the subject of a published randomised controlled trial for pain indications, yet they are projected to become the most widely used type of ...
Australian and New Zealand Society of Blood Transfusion
Every unit of blood transfused presents benefits and risks to the patients. Risks associated with transfusion include:
-febrile reactions
-allergic reactions and anaphylaxis
-haemolytic reactions
-transfusion- transmitted infections
-transfusion-associated acute lung injury, transfusion-associated circulatory overload
-alloimmunisation.
Each unit transfused must have a clear indication and unnecessary transfusions must be avoided.
A restrictive transfusion strategy (Haemoglobin (Hb) of ...
The utilization of tramadol, a weak and mixed centrally acting opioid analgesic, has increased steadily over the past decade, a trend influenced by perceived safety advantages over opioid medications like morphine, oxycodone, and hydrocodone. However, a recent national study reported that older adults account for 33% of tramadol-associated emergency department visits and half of subsequent hospitalizations, suggesting that greater scrutiny of tramadol’s safety in this population is ...
There is strong evidence linking the use of multiple CNS-active medications with serious adverse drug events in older adults. Specifically, older adults taking multiple CNS-active medications are at an increased risk for falls and fractures. Furthermore, the combined use of opioids with gabapentinoids increases the risk of opioid-related death. There is high quality of evidence for avoiding combined use of benzodiazepine receptor agonists (benzodiazepines or Z-drugs defined as zopiclone, ...
