    Amoxicillin structure


    Amoxicillin is used in the treatment of a number of infections, including acute otitis media, streptococcal pharyngitis, pneumonia, skin infections, urinary tract infections, Salmonella infections, Lyme disease, and chlamydia infections. Children with acute otitis media who are younger than 6 months of age are generally treated with amoxicillin or other antibiotic. Although most children with acute otitis media who are older than two years old do not benefit from treatment with amoxicillin or other antibiotic, such treatment may be helpful in children younger than two years old with acute otitis media that is bilateral or accompanied by ear drainage. In the past, amoxicillin was dosed three times daily when used to treat acute otitis media, which resulted in missed doses in routine ambulatory practice. There is now evidence that two times daily dosing or once daily dosing has similar effectiveness. Amoxicillin is recommended as the preferred first-line treatment for community-acquired pneumonia in adults by the National Institute for Health and Care Excellence, either alone (mild to moderate severity disease) or in combination with a macrolide. It is effective as one part of a multi-drug regimen for treatment of stomach infections of Helicobacter pylori. Due to Aeromonas hydrophilia: 1-2 g IV q Day in combination with doxycycline Due to Vibrio vulnificus; 1 g IV q Day in combination with doxycycline Continue treatment until further debridement not necessary, clinical improvement observed, and patient is afebrile for 48-72 hr Uncomplicated gonococcal infection of pharynx, cervix, urethra, or rectum: ceftriaxone 250 mg IM once plus azithromycin 1 g PO once (preferred) or alternatively, doxycycline 100 mg PO q12hr for 7 days CDC STD guidelines: MMWR Recomm Rep.

acute generalized exanthematous pustulosis (AGEP) and isolated cases of severe cutaneous adverse reactions (erythema multiforme, Stevens-Johnson syndrome or Lyell’s syndrome/toxic epidermal necrolysis) Convulsion 10-g pharmacy bulk package should not be used for direct infusion Immune-mediated hemolytic anemia reported; if patient develops anemia while on ceftriaxone, stop antibiotic until etiology determined; severe hemolytic anemia, including fatalities, reported in both adults and children May increase INR, especially in nutritionally deficient patients, hepatic or renal disease or prolonged treatment Dosage must be adjusted in severe renal insufficiency (high dosages may cause CNS toxicity) Superinfections and promotion of nonsusceptible organisms may occur with prolonged use or repeated therapy Use with caution in patients with history of penicillin allergy Use with caution in patients with history of GI disease, especially colitis Use with caution in breast-feeding women; drug may displace bilirubin from albumin-binding sites, increasing risk of kernicterus Abnormal gallbladder sonograms reported, possibly the result of ceftriaxone-calcium precipitates; discontinue if signs or symptoms of gallbladder diseease occur Ceftriaxone-calcium precipitates in urinary tract observed in patients receiving ceftriaxone; may be detected as sonographic abnormalities; patients may be asymptomatic or may develop symptoms of urolithiasis, and ureteral obstruction and post-renal acute renal failure; appears to be reversible upon discontinuation of therapy and institution of appropriate management; ensure adequate hydration; discontinue therapy in patients who develop signs and symptoms suggestive of urolithiasis, oliguria or renal failure and/or the sonographic findings Clostridium difficile-associated diarrhea (CDAD reported with use of nearly all antibacterial agents, including ceftriaxone; If CDAD suspected or confirmed, may consider discontinuing ongoing antibacterial use not directed against C. difficile; institute appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation Pancreatitis secondary to biliary obstruction reported rarely; use with caution in patients with gallbladder, biliary tract, liver, or pancreatic disease and patients with history of penicillin hypersensitivity Inform patients that use of local anesthetics may cause methemoglobinemia, which must be treated promptly; advise patients or caregivers to stop use and seek immediate medical attention if they or someone in their care experience the following signs or symptoms: pale, gray, or blue colored skin (cyanosis); headache; rapid heart rate; shortness of breath; lightheadedness; or fatigue Use with caution in patients with history of GI disease (eg, colitis) Third-generation cephalosporin with broad-spectrum gram-negative activity; has lower efficacy against gram-positive organisms but higher efficacy against resistant organisms; highly stable in presence of beta-lactamases (penicillinase and cephalosporinase) of gram-negative and gram-positive bacteria; bactericidal activity results from inhibiting cell-wall synthesis by binding to 1 or more penicillin-binding proteins; exerts antimicrobial effect by interfering with synthesis of peptidoglycan (major structural component of bacterial cell wall); bacteria eventually lyse because activity of cell-wall autolytic enzymes continues while cell-wall assembly is arrested Distributed throughout body, including gallbladder, lungs, bone, bile, and CSF (higher concentrations achieved when meninges are inflamed); crosses placenta; enters amniotic fluid and breast milk Protein bound: 85-95% Vd: 6-14 L 10 mg/m L; compatible at 1 mg/m L) Additive: Aminophylline, clindamycin, linezolid, theophylline, metronidazole (at metronidazole 15 g/L with ceftriaxone 20 g/L;

Individual plans may vary and formulary information changes. Contact the applicable plan provider for the most current information. All of which are obtained from the soil bacterial species Bacillus brevis and called collectively gramicidin D. Gramicidin D contains linear pentadecapeptides, that is chains made up of 15 amino acids. Gramicidin is active against Gram-positive bacteria, except for the Gram-positive bacilli, and against select Gram-negative organisms, such as Neisseria bacteria. Its therapeutic use is limited to topical application, as it induces hemolysis in lower concentrations than bacteria cell death, so it cannot be administered internally. Since the exterior epidermis is composed of dead cells, applying it to the surface of the skin will not cause harm. It is used primarily as a topical antibiotic and is one of the three constituents of consumer antibiotic polysporin ophthalmic solution. In 1939, the French-born American microbiologist René Dubos isolated the substance tyrothricin and later showed it was composed of two substances, gramicidin (20%) and tyrocidine (80%).
