Warfarin acts by inhibiting the synthesis of vitamin K-dependent clotting factors, which include Factors II, VII, IX, and X, and the anticoagulant proteins C and S. Vitamin K is an essential cofactor for the post ribosomal synthesis of the vitamin K-dependent clotting factors. Vitamin K promotes the biosynthesis of γ-carboxyglutamic acid residues in the proteins that are essential for biological activity. See “ Who should not take Coumadin? Whooping cough poses little danger to children after their first birthdays, and almost no serious risk to older children and adults. But whooping cough does pose a serious danger to children under 1 year old. And even mild whooping cough in older children and adults can cause plenty of lost and days missed from school and work.

Each bottle of clarithromycin granules for oral suspension contains 1250 mg 50 mL size 2500 mg 50 and 100 mL sizes or 5000 mg 100 mL size of clarithromycin. The prognosis for H. pylori infections is usually good to excellent, but up to 20% of affected individuals may have reoccurring infection. Doses of clarithromycin greater than 1000 mg per day should not be co-administered with protease inhibitors. Treatment with anti-infectives may permit overgrowth of clostridia. 1 Consider Clostridium difficile-associated diarrhea and colitis antibiotic-associated pseudomembranous colitis if diarrhea develops and manage accordingly. At least 90 percent of the microorganisms listed below exhibit in vitro minimum inhibitory concentrations MICs less than or equal to the clarithromycin susceptible MIC breakpoint for organisms of similar type to those shown in Table 11. However, the efficacy of clarithromycin in treating clinical infections due to these microorganisms has not been established in adequate and well-controlled clinical trials.

Decrease clarithromycin dose by 50%. Simultaneous administration of clarithromycin tablets and didanosine to 12 HIV-infected adult patients resulted in no statistically significant change in didanosine pharmacokinetics. 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. Renal impairment decreases clearance of clarithromycin and 14-hydroxyclarithromycin. Counsel patients that antibacterial drugs including clarithromycin should only be used to treat bacterial infections.

Stiripentol: May increase the serum concentration of CYP3A4 Substrates. Management: Use of stiripentol with CYP3A4 substrates that are considered to have a narrow therapeutic index should be avoided due to the increased risk for adverse effects and toxicity. Any CYP3A4 substrate used with stiripentol requires closer monitoring. Note: American Heart Association AHA guidelines now recommend prophylaxis only in patients undergoing invasive procedures and in whom underlying cardiac conditions may predispose to a higher risk of adverse outcomes should infection occur. After 3 days of incubation, the MICs are recorded as the lowest concentration of antimicrobial agent required to inhibit growth of the organism. Of the H. influenzae isolated pre-treatment, 3% were resistant to clarithromycin and 10% were resistant to the control agent.
When 250 mg doses of Clarithromycin as an oral suspension were administered to fasting healthy adult subjects, peak plasma concentrations were attained around 3 hours after dosing. The combination of Clarithromycin plus lansoprazole and amoxicillin as triple therapy was effective in eradication of H. pylori see results in Table 18.
