CYP3A inhibitors such as clarithromycin

To reduce the development of drug-resistant bacteria and maintain the effectiveness of clarithromycin and other antibacterial drugs, clarithromycin should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Fernandes PB, Bailer R, Swanson R et al.

Coumadin is prescription medicine used to treat blood clots and to lower the chance of blood clots forming in your body. Blood clots can cause a stroke, heart attack, or other serious conditions if they form in the legs or lungs.

The adverse reaction profiles are shown below Ta ble 7 for four randomized double-blind clinical trials in which patients received the combination of clarithromycin 500 mg three times a day, and omeprazole 40 mg daily for 14 days, followed by omeprazole 20 mg once a day, three studies or 40 mg once a day one study for an additional 14 days. Decreases in MAC bacteremia or negative blood cultures were seen in the majority of patients in clarithromycin. The results also suggest that the increased risk of heart problems may last after patients stop taking clarithromycin, possibly due to the effect that the antibiotic has on the inflammation process in patients with chronic lung conditions, the researchers said.

Since the trial was not designed to determine the benefit of monotherapy beyond 12 weeks, the duration of response may be underestimated for the 25% to 33% of patients who continued to show clinical response after 12 weeks. They found that 26 percent of the patients who received clarithromycin experienced at least one heart problem over the next year, compared with 18 percent of those who were not given the antibiotic.

Food and Drug Administration

Coumadin has a narrow therapeutic range index and its action may be affected by factors such as other drugs and dietary vitamin K. Therefore, anticoagulation must be carefully monitored during Coumadin therapy. Determine the INR daily after the administration of the initial dose until INR results stabilize in the therapeutic range. After stabilization, maintain dosing within the therapeutic range by performing periodic INRs. The frequency of performing INR should be based on the clinical situation but generally acceptable intervals for INR determinations are 1 to 4 weeks. Perform additional INR tests when other warfarin products are interchanged with Coumadin, as well as whenever other medications are initiated, discontinued, or taken irregularly. Prescribing clarithromycin in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria. TraZODone: May enhance the QTc-prolonging effect of Clarithromycin. Clarithromycin may increase the serum concentration of TraZODone.

It can be supposed that this may be due to the induction of CYP3A4 on exposure to substrates. Carbamazepine: Concomitant administration of single doses of Clarithromycin and carbamazepine has been shown to result in increased plasma concentrations of carbamazepine. Blood level monitoring of carbamazepine may be considered. Increased serum concentrations of carbamazepine were observed in clinical trials with Clarithromycin.

Canadian product labeling does not recommend strict avoidance. If combined, monitor for excessive glucocorticoid effects as budesonide exposure may be increased. Susceptible S indicates that the antimicrobial drug is likely to inhibit growth of the pathogen if the antimicrobial drug reaches the concentration usually achievable at the site of infection. A report of Intermediate I indicates that the result should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where high dosage of drug can be used. This category also provides a buffer zone which prevents small uncontrolled technical factors from causing major discrepancies in interpretation. A report of Resistant R indicates that the antimicrobial drug is not likely to inhibit growth of the pathogen if the antimicrobial drug reaches the concentration usually achievable at the infection site; other therapy should be selected. In the study, 122 of the women had first-trimester exposure. The incidence of major and minor congenital malformations did not differ from the background incidence of 1% to 3% and 10% to 15%, respectively, in first-trimester exposure to this drug. The rate of spontaneous abortion in the clarithromycin group was statistically higher than in the control group 14% versus 7%; the authors suggested that the difference could be due to confounding factors not controlled by their study.

Clarithromycin and 91% for the cephalosporin. Patients 60 years or older appear to exhibit greater than expected INR response to the anticoagulant effects of warfarin. The cause of the increased sensitivity to the anticoagulant effects of warfarin in this age group is unknown but may be due to a combination of pharmacokinetic and pharmacodynamic factors. Limited information suggests there is no difference in the clearance of S-warfarin; however, there may be a slight decrease in the clearance of R-warfarin in the elderly as compared to the young.

Flavonoids, a class of natural products of high pharmacological potency. Biochem. Proceedings of ICAAC Chicago 1991. Abstract No. 873. In the acute exacerbation of chronic bronchitis and acute maxillary sinusitis studies overall gastrointestinal adverse reactions were reported by a similar proportion of patients taking either Clarithromycin Tablets, USP or Clarithromycin Extended-Release Tablets; however, patients taking Clarithromycin Extended-Release Tablets reported significantly less severe gastrointestinal symptoms compared to patients taking Clarithromycin Tablets, USP. In addition, patients taking Clarithromycin Extended-Release Tablets had significantly fewer premature discontinuations for drug-related gastrointestinal or abnormal taste adverse reactions compared to Clarithromycin Tablets, USP. linezolid

Trial 5 compared the safety and efficacy of Clarithromycin in combination with ethambutol versus Clarithromycin in combination with ethambutol and clofazimine for the treatment of disseminated MAC dMAC infection. This 24-week trial enrolled 106 patients with AIDS and dMAC, with 55 patients randomized to receive Clarithromycin and ethambutol, and 51 patients randomized to receive Clarithromycin, ethambutol, and clofazime. Baseline characteristics between treatment arms were similar with the exception of median CFU counts being at least 1 log higher in the Clarithromycin, ethambutol, and clofazime arm.

Rivaroxaban: Clarithromycin may increase the serum concentration of Rivaroxaban. Management: In patients with impaired renal function, clarithromycin should not be used unless the potential benefits outweigh the potential risks. This interaction is unlikely clinically significant in patients with normal renal function. In a steady-state study in which healthy elderly subjects 65 years to 81 years of age were given 500 mg of Clarithromycin every 12 hours, the maximum serum concentrations and area under the curves of Clarithromycin and 14-OH Clarithromycin were increased compared to those achieved in healthy young adults. These changes in pharmacokinetics parallel known age-related decreases in renal function. In clinical trials, elderly patients did not have an increased incidence of adverse reactions when compared to younger patients. Consider dosage adjustment in elderly patients with severe renal impairment.

Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. Drugs may interact with Coumadin through pharmacodynamic or pharmacokinetic mechanisms. Pharmacodynamic mechanisms for drug interactions with Coumadin are synergism impaired hemostasis, reduced clotting factor synthesis competitive antagonism vitamin K and alteration of the physiologic control loop for vitamin K metabolism hereditary resistance. Pharmacokinetic mechanisms for drug interactions with Coumadin are mainly enzyme induction, enzyme inhibition, and reduced plasma protein binding. It is important to note that some drugs may interact by more than one mechanism.
