Introduction: There is continued unmet medical need for new medicines across countries especially for cancer, immunological diseases, and orphan diseases. However, there are growing challenges with funding new medicines at ever increasing prices along with funding increased medicine volumes with the growth in both infectious diseases and non-communicable diseases across countries. This has resulted in the development of new models to better manage the entry of new medicines, new financial models being postulated to finance new medicines as well as strategies to improve prescribing efficiency. However, more needs to be done. Consequently, the primary aim of this paper is to consider potential ways to optimize the use of new medicines balancing rising costs with increasing budgetary pressures to stimulate debate especially from a payer perspective.Methods: A narrative review of pharmaceutical policies and implications, as well as possible developments, based on key publications and initiatives known to the co-authors principally from a health authority perspective.Results: A number of initiatives and approaches have been identified including new models to better manage the entry of new medicines based on three pillars (pre-, peri-, and post-launch activities). Within this, we see the growing role of horizon scanning activities starting up to 36 months before launch, managed entry agreements and post launch follow-up. It is also likely there will be greater scrutiny over the effectiveness and value of new cancer medicines given ever increasing prices. This could include establishing minimum effectiveness targets for premium pricing along with re-evaluating prices as more medicines for cancer lose their patent. There will also be a greater involvement of patients especially with orphan diseases. New initiatives could include a greater role of multicriteria decision analysis, as well as looking at the potential for de-linking research and development from commercial activities to enhance affordability.Conclusion: There are a number of ongoing activities across countries to try and fund new valued medicines whilst attaining or maintaining universal healthcare. Such activities will grow with increasing resource pressures and continued unmet need.

Daptomycin is the first approved member of a new class of antibiotics, namely the cyclic lipopeptides. Daptomycin has rapid bactericidal activity against Gram-positive pathogens. It acts by penetrating into the bacterial cell wall with consecutive formation of pores, loss of electrical membrane potential and inhibition of peptidoglycan synthesis. As the mode of action of daptomycin is ‘concentration-dependent’, the pharmacokinetic/pharmacodynamic indices that correlate best with its activity are the ratios of the peak concentration (C_max) to minimum inhibitory concentration (MIC) or the area under the curve (24-hour AUC) to MIC. Daptomycin should be administered intravenously once daily, because adverse effects on skeletal muscle associated with an increase in plasma levels of creatine phosphokinase and myopathy were observed more frequently at shorter dosing intervals. Overall, the rate of adverse events during daptomycin therapy is comparable to that of other standard regimens. Daptomycin was shown to be not inferior to antimicrobial standard therapy and therefore was approved for complicated skin and skin structure infections at a dose of 4 mg/kg, for Staphylococcus aureus bacteremia and right-sided endocarditis at a dose of 6 mg/kg. Dosage regimens remain a matter of discussion, and an increase in the currently approved doses from 4–6 to 6–8 mg/kg per day for severe infections seems promising. Though not approved up to now, daptomycin appears to be a treatment alternative for Gram-positive bone and joint infections based on clinical observations. Large international studies showed high susceptibility of relevant Gram-positive pathogens to daptomycin, even in multidrug-resistant strains. Thus, treatment of infections caused by Gram-positive cocci resistant to other antimicrobial drugs is a potential indication of daptomycin. Since glycopeptides and daptomycin have the same target site, there appears to be a risk of reduced susceptibility to both drugs after consecutive use. Therefore, daptomycin should be used with caution for treatment of vancomycin-resistant isolates or after prior vancomycin (glycopeptide) therapy. This review describes the history, mechanism of action, susceptibility, recent discoveries and clinical experience regarding daptomycin, discussing its current role in the field of infectious diseases.

Our data confirm the view that albumin substantially impairs the antimicrobial activity of antibiotics including moxifloxacin, a member of the class of fluoroquinolones.

Introduction: There are appreciable concerns among European health authorities with growing expenditure on cancer medicines and issues of sustainability. The enhanced use of low cost generics could help. Aims: Consequently, there is a need to comprehensively document current and future arrangements regarding the pricing of generic cancer medicines across Europe, and whether these are indication specific, as well as how this translates into actual prices to provide future direction. Methodology: Mixed method approach with qualitative research among senior health authority personnel and their advisers. Quantitative research via health authority databases to ascertain current prices for oral cancer medicines that had lost their patent and the influence of population size and economics on prices. Results: 25 European countries participated. Currently we see (a) variable approaches to the pricing of generic cancer medicines, which will continue; (b) no concerns with substitution for oral generic cancer medicines; (c) substantial price reductions versus originators for generic capecitabine (up to-93.1%), generic imatinib (up to-97.8%) and generic temozolomide (up to-80.7%). Prices for oncology medicines are not indication specific, and are not affected by population size although influenced by pricing approaches. There have also been price increases for some nonpatented cancer medicines following manufacturer changes although now stabilising. Conclusion: The considerable price reductions seen for some generics means health authorities should further encourage the use of generic oncology medicines when they become available to fund increased volumes and new valued cancer medicines. Countries are also starting to address price increases for generics following changes in the manufacturer

The present study was performed to evaluate the ability of fosfomycin, a broad-spectrum antibiotic, to penetrate into abscess fluid. Twelve patients scheduled for surgical or computer tomography-guided abscess drainage received a single intravenous dose of 8 g of fosfomycin. The fosfomycin concentrations in plasma over time and in pus upon drainage were determined. A pharmacokinetic model was developed to estimate the concentration-time profile of fosfomycin in pus. Individual fosfomycin concentrations in abscess fluid at drainage varied substantially, ranging from below the limit of detection up to 168 mg/liter. The fosfomycin concentrations in pus of the study population correlated neither with plasma levels nor with the individual ratios of abscess surface area to volume. This finding was attributed to highly variable abscess permeability. The average concentration in pus was calculated to be 182 ؎ 64 mg/liter at steady state, exceeding the MIC 50/90 s of several bacterial species which are commonly involved in abscess formation, such as streptococci, staphylococci, and Escherichia coli. Hereby, the exceptionally long mean half-life of fosfomycin of 32 ؎ 39 h in abscess fluid may favor its antimicrobial effect because fosfomycin exerts time-dependent killing. After an initial loading dose of 10 to 12 g, fosfomycin should be administered at doses of 8 g three times per day to reach sufficient concentrations in abscess fluid and plasma. Applying this dosing regimen, fosfomycin levels in abscess fluid are expected to be effective after multiple doses in most patients.

Introduction: There are growing concerns among European health authorities regarding increasing prices for new cancer medicines, prices not necessarily linked to health gain and the implications for the sustainability of their healthcare systems. Areas covered: Narrative discussion principally among payers and their advisers regarding potential approaches to the pricing of new cancer medicines. Expert opinion: A number of potential pricing approaches are discussed including minimum effectiveness levels for new cancer medicines, managed entry agreements, multicriteria decision analyses (MCDAs), differential/tiered pricing, fair pricing models, amortization models as well as de-linkage models. We are likely to see a growth in alternative pricing deliberations in view of ongoing challenges. These include the considerable number of new oncology medicines in development including new gene therapies, new oncology medicines being launched with uncertainty regarding their value, and continued high prices coupled with the extent of confidential discounts for reimbursement. However, balanced against the need for new cancer medicines. This will lead to greater scrutiny over the prices of patent oncology medicines as more standard medicines lose their patent, calls for greater transparency as well as new models including amortization models. We will be monitoring these developments.

Although drainage is considered the gold standard in abscess treatment, abscesses of different sizes and locations have been successfully cured by means of antibiotic treatment alone. The penetration of an antibiotic into an encapsulated purulent lesion is limited and highly dependent on the degree of abscess maturation. In fact, in vivo pharmacokinetic data demonstrate that substantial antibiotic concentrations can be reached within abscesses in humans and animals, provided the choice of an appropriate agent and an optimal dosing regimen. However, the efficacy of antibiotics in pus may be hampered by various factors like low pH, protein binding and degradation by bacterial enzymes. This article provides a comprehensive review on conservative abscess treatment, presenting clinical data on success rates of antibiotic therapy. Antibiotic concentrations measured in abscesses of humans and animals are outlined, and theoretical considerations on the understanding of pharmacokinetics and efficacy of antibiotics in abscesses are discussed.

For fluoroquinolones, standard media might be insufficient to investigate the impact of PB on bacterial killing. MHB containing 12% albumin seems to be a promising medium in this context. For moxifloxacin and trovafloxacin, PB leads to significant reduction of antimicrobial activity.
