Points to consider prior to initiating RETROVIR in pregnant women for the prevention of maternal-fetal HIV-1 transmission include: â¢ In most cases, RETROVIR for prevention of maternal-fetal HIV-1 transmission should be given in combination with other antiretroviral drugs. â¢ Prevention of HIV-1 transmission in women who have received RETROVIR for a prolonged period before pregnancy has not been evaluated.
Vancomycin is an antibiotic drug used to treat serious, life-threatening infections by gram-positive bacteria that are resistant to less-toxic agents. The reference range for vancomycin trough levels is 10-20 Âµg/mL (15-20 Âµg/mL for complicated infections). The reference range for vancomycin peak levels is 25-50 Âµg/mL. Next. Vancomycin trough concentrations below 10 Âµg/mL are associated with inadequate therapy and an increased risk of developing bacterial resistance. Vancomycin trough concentrations above the therapeutic range may increase the risk of nephrotoxicity.
Parabolic trough plant without thermal energy storage have capital costs as low as USD 4 600/kW, but low capacity factors of between 0.2 and 0.25. Adding six hours of thermal energy storage increases capital costs to between USD 7 100/kW to USD 9 800/kW, but allows capacity factors to be doubled.Solar tower plants can cost between USD 6 300 and USD 10 500/kW when energy storage is between 6 and 15 hours.. The levelised cost of electricity (LCOE) from CSP plants is currently high. Assuming the cost of capital is 10%, the LCOE of parabolic trough plants today is in the range USD 0.20 to USD 0.36/kWh and that of solar towers between USD 0.17 and USD 0.29/kWh.
