Its octanol-water partition coefficient at pH 7.4 is 2.6. However, at therapeutic doses no effect on the infant is expected. Fertility and reproductive performance were unaffected in rats at subcutaneous doses up to 80 mcg/kg (approximately equal to the MRHDID on a mcg/m2 basis). 2009; 10:104. In vitro tests show that formoterol is an inhibitor of the release of mast cell mediators, such as histamine and leukotrienes, from the human lung. The results of the study indicated that there was no evidence of a pharmacokinetic interaction between the two components of SYMBICORT. Budesonide/formoterol is a combination of two drugs in a single form used to treat asthma. Budesonide formoterol Mechanism of Action (MOA) Local anti-inflammatory, inhibits the release of inflammatory mediators and the cytokine mediated immune response. Formoterol Fumarate Dihydrate: It is a long-acting, selective β2 - adrenergic agonist with a rapid onset of action. FORACORTINHALER is a combination of budesonide, a potent glucocorticoid, and formoterol fumarate dihydrate, a selective, long-acting beta2-agonist, which have For SYMBICORT, small mean increases in serum glucose and decreases in serum potassium (+0.44 mmol/L and -0.18 mmol/L at the highest dose, respectively) were observed with increasing doses of formoterol, compared to budesonide. In the same study, an open label group of moderate asthma patients received the same dose of SYMBICORT. To determine whether formoterol and salmeterol differentially decreased the β 2-adrenoceptor response to the β 2-agonist isoprenaline, human lung slices containing a small airway were incubated with either formoterol … Peak formoterol plasma concentration of 28 pmol/L occurred at 10 minutes in asthma patients. This is explained by a combination of a relatively high local anti-inflammatory effect, extensive first pass hepatic degradation of orally absorbed drug (85%-95%), and the low potency of formed metabolites.
