The recommeneded dose of Mysolin is 10-25 mg/kg/day divided bid. Determine the maximum recommended dose for a 40 pd child in mg. mg/day 10-25 mg/kg/day 40 pd 2.2 pd/kg mg/day = 10 (25)mg /kg/day x kg /2.2 pd x 40 pd/1 = 182 (455) mg/day min(max) so the maximum would be 455 ? Am I approaching this problem correctly ? 0 Share this post Link to post Share on other sites
