"Feb. 25, 2013 (San Antonio, Texas) -- The asthma drug Xolair appears to be a safe and effective treatment for chronic hives, a new study shows.
The results of the study were presented at a news conference here at the American Academy"...
Mechanism Of Action
Karbinal ER after single-dose administration of 16 mg was bioequivalent to the reference carbinoxamine immediate-release oral solution after the administration of two doses of 8 mg six hours apart under fasting conditions. The carbinoxamine mean (SD) peak plasma concentration (Cmax) was 28.7 (5.3) ng/mL at 6.7 hours after Karbinal ER administration. The plasma half-life of carbinoxamine was 17.0 hours. There was no effect of food on the pharmacokinetic parameters.
Karbinal ER after multiple-dose administration of 16 mg every 12 hours for 8 days was bioequivalent to the reference carbinoxamine immediate-release oral solution after multiple-dose administration of 8 mg every 6 hours. The mean (SD) steady-state Cmax was 72.9 (24.4) ng/mL at 5.6 hours after Karbinal ER administration. Carbinoxamine mean (SD) minimum plasma concentration at steady-state was 51.8 (20.3) ng/mL.
The efficacy and safety of Karbinal ER is based on demonstration of bioequivalence to the immediaterelease reference product [see Pharmacokinetics].
