Meropenem IV 1 g q8h purchase erythromycin 250mg with amex, as a 3 mo and older: IV (Merrem) bolus injection 20–40 mg/kg q8h over 3–5 min or Penicillinase-Resistant (Antistaphylococcal) infusion over Penicillins 15–30 min This group includes four drugs (cloxacillin purchase 500mg erythromycin with visa, dicloxacillin, naf- Monobactam cillin, and oxacillin) that are effective in some infections caused Aztreonam UTI, IM, IV 0. An older member of Moderate systemic this group, methicillin, is no longer marketed for clinical use. These drugs are formulated to resist the penicillinases that UTI, urinary tract infection. They are recommended for use in known or suspected staphylococcal infections, except for methicillin-resistant Staphylococcus aureus (MRSA) infections. Although called methicillin-resistant, these tococci, staphylococci, and other microorganisms continues staphylococcal microorganisms are also resistant to other to grow. Aminopenicillins Contraindications to Use Ampicillin is a broad-spectrum, semisynthetic penicillin that Contraindications include hypersensitivity or allergic reac- is bactericidal for several types of gram-positive and gram- tions to any penicillin preparation. It has been effective against enterococci, penicillin means the client is allergic to all members of the Proteus mirabilis, Salmonella, Shigella, and Escherichia penicillin class. The potential for cross-allergenicity with coli, but resistant forms of these organisms are increasing. It cephalosporins and carbapenems exists, so other alternatives is ineffective against penicillinase-producing staphylococci should be selected in pencillin-allergic clients when possible. Ampicillin is excreted mainly by the kidneys; thus, it is useful in urinary tract infections (UTI). Because some is ex- Subgroups and Individual Penicillins creted in bile, it is useful in biliary tract infections not caused by biliary obstruction. It is used in the treatment of bronchitis, Penicillins G and V sinusitis, and otitis media. Amoxicillin is similar to ampicillin except it is only avail- Penicillin G, the prototype, remains widely used because able orally. It is better absorbed and produces therapeutic of its effectiveness and minimal toxicity.

When drug actions are not urgent effective erythromycin 500mg, therapy may be on other characteristics. In general, different salts of the same drug rarely differ pharmacologically. Pharmacists and chemists choose Nursing Notes: Apply Your Knowledge salts on the basis of cost, convenience, solubility, and stability. For example, solubility is especially important with parenteral drugs; taste is a factor with oral drugs.

CHAPTER 4 NURSING PROCESS IN DRUG THERAPY 61 Neonates, Infants, and Children: Physiologic Characteristics and TABLE 4–2 Pharmacokinetic Consequences Physiologic Characteristics Pharmacokinetic Consequences Increased thinness and permeability of skin in Increased absorption of topical drugs (eg, corticosteroids may be absorbed sufficiently to neonates and infants suppress adrenocortical function) Immature blood–brain barrier in neonates Increased distribution of drugs into the central nervous system because myelinization and infants (which creates the blood–brain barrier to the passage of drugs) is not mature until approximately 2 years of age Increased percentage of body water (70% Usually increased volume of distribution in infants and young children, compared with to 80% in neonates and infants, compared with adults. However, prolonged drug 50% to 60% in children older than 2 years of half-life and decreased rate of drug clearance may offset. Altered protein binding until approximately 1 year The amount and binding capacity of plasma proteins may be reduced. This may result in of age, when it reaches adult levels a greater proportion of unbound or pharmacologically active drug and greater risks of adverse drug effects. Drugs with decreased protein binding in neonates, compared with older children and adults, include ampicillin (Omnipen, others), diazepam (Valium), digoxin (Lanoxin), Iidocaine (Xylocaine), nafcillin (Unipen), phenobarbital, phenytoin (Dilantin), salicylates (eg, aspirin), and theophylline (Theolair). Decreased glomerular filtration rate in neonates In neonates and infants, slowed excretion of drugs eliminated by the kidneys. Decreased activity of liver drug-metabolizing Decreased capacity for biotransformation of drugs. This results in slowed metabolism and enzyme systems in neonates and infants elimination, with increased risks of drug accumulation and adverse effects. Increased activity of liver drug-metabolizing Increased capacity for biotransformation of some drugs. This results in a rapid rate of enzyme systems in children metabolism and elimination.
