Review
Teicoplanin, a new glycopeptide antibiotic similar to vancomycin, has proved effective in the treatment of various gram-positive infections in both the normal and the immunocompromised host. In vitro activity against most gram-positive organisms is equal to or greater than that of vancomycin. In both open and comparative clinical trials, teicoplanin has been well tolerated, rarely prompting discontinuation of treatment. Nephrotoxicity caused by teicoplanin is uncommon, even when used concomitantly with aminoglycosides or cyclosporin A. Favorable pharmacokinetics allow for intramuscular administration as well as intravenous bolus dosing, and, after appropriate loading doses, maintenance therapy may be given on a once-daily basis. The combination of all of these factors makes teicoplanin an effective, safe alternative to vancomycin in the treatment of gram-positive infections.

Review
Teicoplanin (Tcp) is a clinically relevant glycopeptide antibiotic (GPA) that is produced by the actinobacterium Actinoplanes teichomyceticus. Tcp is a front-line therapy for treating severe infections caused by multidrug-resistant Gram-positive pathogens in adults and infants. In this review, we provide a detailed overview of how Tcp is produced by A. teichomyceticus by describing Tcp biosynthesis, regulation, and resistance. We summarize the knowledge gained from in vivo and in vitro studies to provide an integrated model of teicoplanin biosynthesis. Then, we discuss genetic and nutritional factors that contribute to the regulation of teicoplanin biosynthesis, focusing on those that have been successfully applied for improving teicoplanin production. A current view on teicoplanin self-resistance mechanisms in A. teichomyceticus is given, and we compare the Tcp biosynthetic gene cluster with other glycopeptide gene clusters from actinoplanetes and from unidentified isolates/metagenomics samples. Finally, we provide an outlook for further directions in studying Tcp biosynthesis and regulation.

Review
Individualization of antimicrobial treatment based on real-time therapeutic drug monitoring (TDM) and dosing adaptation may represent an important tool in the antimicrobial stewardship programs. Teicoplanin is a glycopeptide hydrophilic antibiotic whose pharmacokinetic behavior may consistently vary among different patient populations. Nowadays it is generally recognized that the effective trough (C) plasma level of tecoplanin should be of at least 10-15 mg/L for the treatment of mild infections, and of 15-30 mg/L for the treatment of deep-seated infections and/or of severe infections. The aim of this viewpoint is to provide an update for optimal use of teicoplanin TDM in different patient populations. Available literature supports TDM of C as a helpful approach in addressing appropriate treatment with teicoplanin, with a frequency of assessment that should be guided by the severity of the infection and/or by the complexity of the pathophysiological status of the patient.

Review
The teichomycin antibiotics have been discovered and chemically purified in the late 1970s. Teicoplanin, one of the major derivatives of this group, has been introduced into clinical use in 1984. In Germany, teicoplanin was licensed in 1988 and now ranks among the antimicrobial agents most frequently used in intensive care units. Due to its reduced rate of side effects compared to vancomycin, its longer serum half-life and a simplified mode of application, teicoplanin has become the glycopeptide of choice in many hospitals. The present review summarizes in vitro activity data, pharmacokinetics, and clinical experience with teicoplanin, with special consideration of currently recommended doses and serum levels.

Comparative Study Review
Since an earlier review in the Journal substantial additional data have accumulated, further clarifying the in vitro activity, pharmacokinetic profile, clinical efficacy and tolerability of teicoplanin. Recent therapeutic trials confirm the efficacy of teicoplanin in the treatment of microbiologically confirmed Gram-positive infections, including septicaemia, endocarditis, and infections of skin and soft tissue, bone and joints, and the lower respiratory tract. As teicoplanin can be administered once daily intramuscularly as well as intravenously, it has potential for outpatient treatment of severe Gram-positive infections. Teicoplanin is appropriate as treatment of patients with fever and neutropenia, but there is still controversy over the timing for introduction of glycopeptide antibiotics into therapeutic regimens. Teicoplanin is generally reserved for secondary therapy of patients with documented bacteraemia who fail to respond to initial empirical antibiotic regimens, but probably should be part of the initial empirical regimen in the setting of a high incidence of methicillin-resistant staphylococci. Teicoplanin has a lower propensity than vancomycin to impair renal function when either drug is combined with an aminoglycoside, causes fewer anaphylactoid reactions, and appears to be of comparable efficacy. Thus, teicoplanin may be preferred to vancomycin in the treatment of Gram-positive infections, and where a glycopeptide antibiotic is deemed a necessary inclusion in a regimen for empirical treatment in patients with fever and neutropenia.

Review
The glycopeptide antibiotics vancomycin and teicoplanin have similar mechanisms of action on bacterial cell wall synthesis. Their spectra of activity are limited to Gram-positive bacteria, with the degree of bactericidal activity depending on the species of micro-organism. Staphylococcus aureus, Staphylococcus epidermis, enterococci and Clostridium difficile are generally sensitive, including methicillin-resistant strains of S. aureus and S. epidermidis. Glycopeptide resistance has recently emerged in staphylococci and enterococci. Vancomycin has a shorter half-life than teicoplanin and requires multiple dosing to maintain adequate serum levels. It can only be given by prolonged intravenous infusion over 1 h. In contrast, the pharmacokinetics of teicoplanin allow for once-daily dosing, either by rapid intravenous infusion or by the intramuscular route. The latter offers reliable absorption for patients with limited venous access and is also of benefit for out-patient therapy. Teicoplanin is a safer drug than vancomycin. It is associated with a lower incidence of nephrotoxicity or ototoxicity. Compared to vancomycin, the availability of the intramuscular route and the absence of a requirement for routine serum monitoring, together with the reduced need to treat drug-related side-effects make teicoplanin more cost-effective. It is as effective as vancomycin for most indications, is safe, easy to administer and an important agent for treating Gram-positive infections. Its role in hospitals is likely to increase if the price of drug acquisition is kept low.

Review
The glycopeptide antibacterial teicoplanin has become increasingly popular in the last decade with the rise in infections related to methicillin-resistant Staphylococcus aureus. Teicoplanin has 6 major and 4 minor components. It is predominantly (90%) bound to plasma proteins. Of the several methods available to measure concentrations in serum, fluorescence polarisation immunoassay has high reliability and specificity. Teicoplanin is not absorbed orally, but intravenous and intramuscular administration are well tolerated. Teicoplanin is eliminated predominantly by the kidneys and only 2 to 3% of an intravenously administered dose is metabolised. Total clearance is 11 ml/h/kg. Steady state is reached only slowly, 93% after 14 days of repeated administration. Elimination is triexponential, with half-lives of 0.4 to 1.0, 9.7 to 15.4 and 83 to 168 hours. Volumes of distribution are 0.07 to 0.11 (initial phase), 1.3 to 1.5 (distribution phase) and 0.9 to 1.6 (steady state) L/kg. A standard dosage regimen of 6 mg/kg every 12 hours for 3 doses, then daily, will produce therapeutic serum concentrations of > or = 10 mg/L in most patients. Higher dosages may be required in certain patients, for example intravenous drug abusers or those with burns, because of unpredictable clearance. Concentrations in bone reach 7 mg/L at 12 hours after a dose of teicoplanin 6 mg/kg, but reach only 3.5 mg/L in the cartilage. Doses of 10 mg/kg are necessary to achieve adequate bone concentrations. There is little penetration into cerebrospinal fluid or the aqueous or vitreous humour. In fat, concentrations may be subtherapeutic (0.5 to 5 mg/L) after a dose of 400mg. A single prophylactic dose of 12 mg/kg is sufficient to maintain therapeutic concentrations during cardiopulmonary bypass or burns surgery. High loading doses reduce the delay to attaining therapeutic concentrations. Premature neonates require a loading dose of 15 mg/kg and a maintenance dosage of 8 mg/kg daily to ensure therapeutic serum concentrations. Children need loading with 10 mg/kg every 12 hours for 3 doses followed by maintenance with 10 mg/kg/day. Clearance is reduced predictably in renal failure, and dosage adjustments can be based on the ratio of impaired clearance to normal clearance. In patients on haemodialysis, 3 loading doses of 6 mg/kg at 12-hour intervals followed by maintenance doses every 72 hours produced trough plasma concentrations of 8 mg/L in most patients at 48 hours. The monitoring of serum concentrations is not necessary to avoid toxicity, but can be helpful in certain patient groups to ensure therapeutic concentrations are present, especially in those not responding to treatment.

Review
Teicoplanin is a glycopeptide antibiotic whose activity is selectively oriented against Gram-positive aerobic and anaerobic bacteria, including Staphylococcus aureus, coagulase-negative staphylococci, Clostridium difficile, Peptostreptococcus spp. and Corynebacterium jeikeium; such activity is affected by neither methicillin resistance nor beta-lactamase production. Teicoplanin is not significantly absorbed from the gastrointestinal tract; consequently, it has to be administered intravenously (either by infusion or by rapid injection) or intramuscularly. Its long half-life allows regimens based upon once daily administration. The adverse effects most frequently associated with teicoplanin treatment are local and hypersensitivity reactions, such as itching and drug fever; anaphylactoid reactions (the 'red man syndrome') are seldom observed. Teicoplanin also has less potential than vancomycin to cause nephrotoxicity, especially when administered in combination with an aminoglycoside. Teicoplanin has been proven to be effective in the treatment of microbiologically documented Gram-positive infections, including 'difficult to treat infections' such as endocarditis and prosthetic infections. Furthermore, recent trials in patients with haematological malignancies or other cancers have clearly demonstrated that teicoplanin is at least as efficacious as vancomycin in the empirical initial antibiotic regimen for febrile neutropenic patients, and is associated with fewer adverse effects. Finally, owing to its good tolerability profile and the advantage of once daily administration by both intravenous and intramuscular routes, teicoplanin has proven to be very useful for the outpatient treatment of serious Gram-positive infections. In conclusion, teicoplanin is potentially an effective alternative to vancomycin both in immunocompetent and immunocompromised patients, with the advantage over vancomycin of single daily dose administration and lower toxicity. Further comparative studies with vancomycin are, however, required to better define the therapeutic role of teicoplanin for particular infections (i.e. infective endocarditis).

Review
Dalbavancin is a synthetic lipoglycopeptide that exerts its antimicrobial activity through two distinct modes of action, inhibition of cell wall synthesis and an anchoring mechanism. Compared with previous glycopeptide antibiotics, dalbavancin demonstrates improved antibacterial potency against Gram-positive organisms and a long half-life of approximately 1 week, which is longer in tissues (e.g., skin, bone) than plasma. These factors facilitated the development of single-dose or once-weekly dosing regimens to treat acute bacterial skin and skin structure infections (ABSSSI). Dalbavancin exhibits dose-proportional pharmacokinetics and is highly protein bound (93%). Despite being highly protein bound, it has a steady-state volume of distribution >10 L and distributes widely into the skin, bone, peritoneal space, and epithelial lining fluid, but not cerebrospinal fluid. Dalbavancin elimination occurs via a combination of renal (approximately 45%) and non-renal clearance, with dose adjustments recommended only in patients with a creatinine clearance <30 mL/min not receiving any form of dialysis. The established pharmacokinetic/pharmacodynamic index associated with bacterial kill is free area under the concentration-time curve over the minimum inhibitory concentration (fAUC/MIC), with a goal 24-h fAUC/MIC of at least 27.1 for Staphylococcus aureus infections. Recent data suggest usefulness in the treatment of infections beyond ABSSSI, with convenient dosing and redosing strategies for complicated infections requiring extended treatment durations. Additional studies are needed to confirm these preliminary findings.
