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.
A d/p cell usually provides accuracy of Â±0.2% of the calibrated span (CS). This means that, at the low end of a 10:1 flow range (at 10% flow), corresponding to a differential pressure range of 100:1, the flowmeter would have an error of Â±20% AR. For this reason, differential producing flowmeters have historically been limited to use within a 3:1 or 4:1 range.
