But, given that few other outpatient drug treatments cause serious injuries to 6 or more patients treated for a year, the need is great to reduce the risks associated with this class of drugs. Some practical steps for fda, the pharmaceutical industry, and the cardiology/hematology community to take in this regard include Ensure wide availability of antidotes for bleeding induced by direct oral anticoagulants. The cdc study shows anticoagulant hemorrhages are to be expected in EDs. Establish guidelines for combined therapy with anti-platelet agents (i.e., aspirin, clopidogrel, prasugrel) and oral anticoagulants, especially in older patients. Combining various antithrombotics increases the risk of bleeding, but little information is available to guide when this therapy provides sufficient benefits that outweigh the increased risks. Re-evaluate the suitability of rivaroxabans once-a-day dosing compared to similar anticoagulants with a dosing scheme better matched to the drugs half-life. While clinical trial results for rivaroxaban suggest risks and benefits similar to warfarin,2 safety gains are likely with twice-daily dosing.9 Provide therapeutic ranges for dabigatran to identify patients with suboptimal or excessive anticoagulation. A drug with a 5-fold variability in anticoagulant effect at the same dose needs a recommended blood testing method to identify those with a dose outside a therapeutic range.

The second dabigatran safety issue that was addressed involved the unavailability of a make reduced dose for older patients or those with moderately impaired renal function. In the us, the drug had been limited to a single 150 mg good dose (twice daily) and an untested 75 mg dose for patients with severe renal impairment. But in late 2015, fda authorized an intermediate 110 mg dose, which previously had been available in many other countries, for deep vein thrombosis and pulmonary embolus prevention following hip replacement surgery. (Although us prescribing information still does not recommend the intermediate dose to treat atrial fibrillation, the european Medicines Agency recommends its use in patients 75 years or older and/or with one or more risk factors for bleeding.6) However, by the end of 2016, there was. The unresolved safety issue with dabigatran relates to its 5-fold variability in anticoagulant effect in patients receiving the same dose.7 This results in at least 40 of dabigatran patients receiving a suboptimal dose, according to simulation studies. Rivaroxaban/apixaban antidote not approved. While fda approved an antidote for dabigatran, it declined to approve a similar antidote for rivaroxaban and apixaban, developed by portola Pharmaceuticals. Despite this drug achieving similar results to the dabigatran antidote in a published study,8 the company said fda had declined to approve the drug in June 2016, citing manufacturing issues. Conclusion and Practical Steps to reduce harm From the onset, long-term use of oral anticoagulants exemplified a dangerous balance between a clearly demonstrated benefit in preventing ischemic stroke against the high risk of bleeding and fewer-in-number but substantially increased risk of hemorrhagic strokes. Many healthcare professionals have been willing to risk causing more hemorrhages that can be treated in order to prevent disabling, life-changing ischemic strokes.
Only apixaban, with two dosing options that take into consideration patient-specific characteristic such as age, renal function, and body weight, had a credible claim to a modest improvement in safety over warfarin.1. By the end write of 2016, two safety concerns with dabigatran had been addressed, at least in part. It became the first direct oral anticoagulant with an fda-approved antidote for dabigatran-related hemorrhage. Cizu mab praxbind ) is a monoclonal antibody that binds to dabigatran, rendering it ineffective. An fda clinical review of the drug found it was notably effective in returning blood clotting function to normal within 10-30 minutes of infusion.5 While the anticoagulant effect was quickly neutralized, bleeding continued in many cases. The median time to halt the bleeding was.8 hours, and one patient bled for 62 days. Of the 123 patients in which the antidote was tested, 26 died despite the antidote. These results emphasize the importance of preventing hemorrhages rather than treating them.
Pradaxa rivaroxaban xarelto apixaban eliquis and edoxaban (. Savaysa they designed them to be easier to use than warfarin but not necessarily safer. While warfarin required frequent laboratory monitoring and individual dose adjustments, the direct oral anticoagulants were tested and approved at only one or two therapeutic doses, with no laboratory monitoring for efficacy required, recommended, or, in most cases, possible. However, two of the four newer anticoagulants proved to be poorly suited to simplified dosing schemes. Soon after approval of the first agent, dabigatran, quarterWatch raised questions about whether its single therapeutic dose was causing excess bleeding in the elderly. A second agent, rivaroxaban, was marketed for easier once-a-day dosing despite having a shorter half-life than the other direct oral anticoagulants. QuarterWatch reports, noted that this pharmacodynamic limitation of rivaroxaban resulted in higher than optimal anticoagulation early in the 24-hour cycle, and potentially suboptimal effects later after the body cleared much of the active drug. Based on clinical trials, edoxaban is not recommended in patients with non-valvular atrial fibrillation if they have a creatinine clearance greater than 95 mL/minute because of an increased risk of ischemic stroke compared to warfarin.
While not strictly comparable, the cdcs systematic study shows an estimated 228,600 annual ed visits due to anticoagulants, or more than 10 times the faers total number of voluntary reports. Keep in mind that the cdc study only captured outpatient events requiring a visit to the. For oral anticoagulants, the study did not capture direct hospital admissions, doctors office visits, and out-of-hospital deaths. On the other hand, the reported cdc events included a substantial number of cases in which a patient had an elevated inr and was subsequently sent to the ed to assess overdose risk but did not experience an acute injury. Discussion, new anticoagulants took a wrong turn. Since 1954, warfarin has been a standard but hazardous treatment for preventing blood clots, particularly clots associated with atrial fibrillation. When the pharmaceutical industry began marketing modern replacements for warfarin (direct oral anticoagulants including dabigatran (.

Gastrointestinal hemorrhages were the most numerous (n8,495 but we also identified 1,019 cerebral hemorrhages and another 790 possible cases of cerebral hemorrhage. In other cases, the site of bleeding was not identified. The only other notable adverse effect reported with anticoagulants was renal failure and impairment (n835). Cdc study of ed visits. A recently published cdc study of ed visits from 2013 to 2014 associated with adverse drug events confirms and extends these findings.4 The cdc study showed that anticoagulants accounted for.6 of all ed visits for outpatient adverse drug effects, more than any other class. The anticoagulant events were mostly severe, with.8 overall requiring hospitalization (63.8 for patients taking dabigatran,.4 for rivaroxaban,.5 for warfarin).
For comparison,.6 of patients were hospitalized after an ed visit linked to the therapeutic use of opioids, and.1 were hospitalized after a visit due to an antibiotic reaction. Using the cdc data, quarterWatch estimates that.3 of patients exposed to an anticoagulant for 1 year will require an ed visit due to the drugs adverse effects. According to the cdc study, ed visits for anticoagulant adverse drug effects increased good between. Anticoagulant-related ed visits increased more than 2-fold, reflecting higher use of anticoagulants, different drugs that may have increased risk, and better wallpaper event identification in the study. In the 2 years since 2014 (the cut-off date for the cdc study overall use of anticoagulants has continued to increase, with the newer direct oral anticoagulants replacing some warfarin use. The cdc data also illustrate that faers voluntary reporting underestimates drug-related injuries that are actually occurring.
The latest annual report of ismps. QuarterWatch analyzes more than.2 million new adverse drug event reports submitted to the us food and Drug Administration (FDA) Adverse event Reporting System (faers) during 2016. Part i of this newsletter feature, which appeared in the. July 13, 2017 issue, examined drug withdrawal symptoms reported by large populations of patients who have stopped taking opioids, antidepressants, and certain neuropathic pain, antianxiety, and sedative/hypnotic medications. Part ii, we examine the high risk of acute injuries linked to oral anticoagulants and outline five practical measures to improve safe use.
Measures of Harm, harm from oral anticoagulants ranks as one of the highest priority drug safety problems in 2016 by several measures. First, in clinical trials, these drugs have repeatedly demonstrated high injury rates, causing bleeding in 8 to 19 of patients treated for a year.1-3 Next, anticoagulants are used by a large and growing population, notably the elderly, with an estimated.8 million person-years exposure. Overall exposure to oral anticoagulants increased.6 between the 4th quarter of 2015 and the same quarter in 2016 (see. Reports of serious injuries and death also feature prominently in the 2016 faers data, as well as in a systematic study of emergency department (ED) visits for adverse drug events conducted by the centers for Disease control and Prevention (CDC) and published in late 2016.4. What the data Show 2016 faers data. In the 2016 data, anticoagulants continue to account for large numbers of reported serious injuries (n18,978) and deaths (n3,018) in the. The primary suspect drugs were rivaroxaban (n15,043;.4 apixaban (n3,148;.3 dabigatran (n1,944;.8 warfarin (n1,753; 8 and edoxaban (n108; less than 1). (rivaroxaban totals were increased by large numbers of reports with event dates in prior years but first reported to fda in 2016; reported events for edoxaban were much lower than for the other direct oral anticoagulants and warfarin because of a more restrictive indication and. Practically all reported injuries or deaths were from hemorrhages (n17,218;.3 making bleeding one of the most frequently reported serious adverse drug effects of all types.

Smelling the patients breath is the easiest and most commonly used method of detection. Normal breath of a healthy patient should have no odor or a slightly sweet smell. When the odor is not limited to the mouth, but also is recognized through the nose, it can be assumed that the odor may have a systemic or non-oral origin. Chronic oral malodor is a common dental problem and may cause patients to seclude themselves from social activities fearing the shame the condition brings.2. Remember to be sensitive to your patients concerns. If chronic halitosis persists and the patient is no longer on a low-carb diet, refer the patient to be medically evaluated because it can and should be a health concern.

Dietary sucrose also may have an effect on plaque accumulation and bacterial population. The results of a study conducted by carlsson and Egelberg6 found plaque formation during intake of sucrose was much thicker and heavier than that formed during glucose supplementation. Various studies7,8,9 have concluded a reduction in matter the amount of lactobacilli and/or streptococcus mutans in plaque and saliva when sucrose intake is low, and an increase in these microorganisms during a sucrose-rich diet. And the cons, restricted carbohydrate intake also may have a negative effect on the oral cavity. It encourages the breakdown of fat stored for energy instead of glucose, a process known as ketosis or dietary ketosis. The breakdown of fats results in three different molecules called ketones, two of which (acetoacetate and ß-hydroxybutyrate) can be used for energy by most body tissues. The third ketone, acetone, cannot be used by the body and is excreted in the urine and exhaled by the lungs, causing halitosis.10,11.
oral cavity. In conjunction with plaque, it contains minerals and trace elements such as fluoride, calcium and phosphorus that contribute to the remineralization of enamel. Calcium and phosphorus also are useful in the maintenance of the supportive alveolar bone. The pros to low-carb, food residues, specifically carbohydrates, have caries promoting characteristics that allow fermentation and acid accumulation to occur in bacterial plaque.3 It enhances the four previously mentioned activities of biofilm: implantation, colonization, metabolic activity and thickness. When carbs are restricted in a diet, it limits an essential factor for the development of caries. The vipeholm study4 in 1954 first established the strong relationship between consumption and dental caries. It was supported by the investigation of Sreebny5 in 1982, which described the extensive reviews on the study, reaffirming its results. The literature concluded that a very low intake of sugar showed very low caries scores, and those that included a very high amount of sugar in their diets developed high numbers of carious lesions.
Streptococcus mutans and lactobacilli are bacteria found in biofilm that are highly cariogenic. Their cariogenic action has four aspects considered as separate effects:3. Implantation mechanism involving adhesion. Colonization through competition with other bacterial components. Metabolic activity of established bacteria under the influence of food residues and oral environment. Increased thickness of plaque and its control by oral hygiene. Recommend to your patients the following suggestions by the Academy of General Dentistry: Drink plenty of water, chew sugarless gum with Xylitol or write suck on sugarless mints.

One of shredder the longest trends in appetite control has been the low-carbohydrate diet. Many patients, when filling out their medical, dental and personal history, reveal they follow these patterns of eating. Nutrition may have stabilizing or damaging effects on the oral cavity, so as registered dental hygienists, we are in the perfect position to discuss the effects of low-carb dieting on the oral cavity, including the topic people are most embarrassed about: halitosis. Theoretically, when shrinking your waistline, there should be a reduction in the occurrence of carious lesions. Fermentable carbohydrates, especially sucrose, are absorbed by biofilm. This process causes bacterial plaque to produce acids.1. Frequent exposure of a susceptible tooth surface to the acid causes demineralization, the initiation of the caries process.2 Progressive, intermittent demineralization of the tooth structure may progress into complete destruction of coronal dental tissues and development of pulpal abscesses. Where caries come from, the etiology of dental caries is multifactorial. The chart to the left offers a visual guide.
