Preventable Cases of Oral Anticoagulant-Induced Bleeding: Data From the Spontaneous Reporting System
Conclusion: Our findings describe the most reported risk factors for preventability of oral anticoagulant-induced bleedings. These factors may be useful for targeting interventions to improve pharmacovigilance activities in our regional territory and to reduce the burden of medication errors and inappropriate prescription. Introduction Oral anticoagulant therapy is widely used for the prevention of stroke and systemic embolism in patients with atrial fibrillation, or for the prevention and treatment of deep vein thrombosis and pulmonary embolism (Raj et al., 1994; Monaco et al., 2017). Oral anticoagulants can be di...

Literature Update in Hospital Medicine
Publication date: April 2014 Source:Hospital Medicine Clinics, Volume 3, Issue 2 Author(s): William Southern , Bradley A. Sharpe , Romsai Tony BoonyasaiTeaser Perioperative statins reduce perioperative myocardial infarctions, atrial fibrillation, and length of stay. Statins do not increase the risk of intracranial hemorrhage. New oral anticoagulants are superior to warfarin in preventing stroke in patients with atrial fibrillation, and may have a better safety profile. In patients who have an acute gastrointestinal bleed while on warfarin, restarting warfarin after a week may lead to fewer thromboses and lower mortality ...

Drug-drug interactions associated with antiplatelet therapy.
Authors: Dunn SP, Macaulay TE Abstract Antiplatelet therapy is of paramount importance in the treatment and prevention of adverse cardiovascular events and stroke. Drug-drug interactions (DDIs) among antiplatelet therapies have been growing in both prevalence and clinical importance. Most DDIs with antiplatelet therapies are pharmacodynamic in nature. DDIs with thienopyridines and proton pump inhibitors have resulted in advisories from regulatory agencies although the full significance of this interaction is unknown. Other DDIs with thienopyridines may potentially exist with statins, calcium channel blockers, and w...

Medicines and Vegetable Oils as Hidden Causes of Cardiovascular Disease and Diabetes
Background: Positive associations have been observed between cardiovascular disease (CVD) and type 2 diabetes mellitus (DM), but their causal relationship has not been clarified. Nevertheless, guidelines from relevant medical societies recommend using cholesterol lowering medication (statin) for both types of patients. Medicines with several different action mechanisms have been developed, and the effectiveness of different lifestyle modifications has been studied extensively for the prevention of DM, which was successful in improving clinical marker status in relatively short-term treatments, but none have been shown to b...

Use of Pharmacogenetic Information in the Treatment of Cardiovascular Disease Reviews
BACKGROUND: In 1964, Robert A. O'Reilly's research group identified members of a family who required remarkably high warfarin doses (up to 145 mg/day, 20 times the average dose) to achieve appropriate anticoagulation. Since this time, pharmacogenetics has become a mainstay of cardiovascular science, and genetic variants have been implicated in several fundamental classes of medications used in cardiovascular medicine. CONTENT: In this review, we discuss genetic variants that affect drug response to 3 classes of cardiovascular drugs: statins, platelet P2Y12 inhibitors, and anticoagulants. These genetic variations have phar...

Co-morbidity and clinically significant interactions between antiepileptic drugs and other drugs in elderly patients with newly diagnosed epilepsy
Conclusions Elderly patients with newly diagnosed epilepsy are at high risk of clinically relevant pharmacokinetic interactions with other drugs, especially if exposed to carbamazepine, but these interactions can be controlled via rational drug choices and with prediction of the possible drug-to-drug interactions. Patients on dihydropyridine calcium-channel blockers, statins, warfarin, and risperidone face the highest risk of interactions.

Interaction between warfarin and astaxanthin: A case report
This report explains the potential interaction between warfarin and astaxanthin in a 69-year-old Thai woman with history of ischemic stroke. Before taking astaxanthin, the patient used constant doses of warfarin, atenolol, digoxin, aspirin, omeprazole, and simvastatin concomitantly for 17 days without any signs and symptoms of adverse events. One day after astaxanthin was supplemented to her treatment regimen, ecchymosis was found on the right side of her groin and thigh. On the next day, area of ecchymosis was larger. International normalized ratio (INR) values increased from 1.4 to 10.38. Warfarin and astaxanthin were wi...

Rhabdomyolysis due to warfarin and atorvastatin combination therapy in a patient with ischemic heart disease: (A drug interaction)
CONCLUSION: Statins are widely prescribed to patients with cardiovascular problems. Therefore, clinicians should pay attention to the patient's medical history, current prescribed doses, and drug interactions when adding new drugs or adjusting existing drugs.PMID:35242328 | PMC:PMC8861410 | DOI:10.1016/j.amsu.2022.103384
