Journal of Pharmaceutical Sciences, 1973
Abstract: Known amounts of isoproterenol, phenylephrine, and epinephrine were added to the aqueous oxymix system and thereby exposed to potential redox destruction. Thirty minutes later, recoveries of isoproterenol and phenylephrine were 89-100% and 89-108%, respectively, while the recovery of epinephrine was 53-79%.

Humidification, Nebulization, and Bronchodilator Agents

1978
These defense mechanisms include: (a) ciliary escalator system—the mucus carpet carrying microorganisms and small foreign particles at a normal rate of about 1 cm/min from bronchioles and bronchi to the larynx entrance, (b) coughing, and (c) phagocytosis—macrophages in alveoli clearing via interstitial spaces (lymphatics) and upward via the ciliary ...

In vitro studies on the relative potency of bronchodilator agents

Lung, 1985
This study describes a rapid in vitro assay for the order of potency of bronchodilator drugs using specific binding of (−)-[3H] dihydroalprenolol ([3H]DHA) to rat lung membranes. Under linear conditions with respect to tissue, specific binding of [3H]DHA showed saturability, rapid kinetics of association and dissociation of radioligand, and ...
