Aminophylline is a compound of the bronchodilator theophylline with ethylenediamine in 2:1 ratio. The ethylenediamine improves solubility, and the aminophylline is usually found as a dihydrate. [2] Aminophylline is less potent and shorter-acting than theophylline. Its most common use is in the treatment of airway obstruction from asthma or COPD.
Diphenhydramine is the primary constituent of dimenhydrinate and dictates the primary effect. The main differences relative to pure diphenhydramine are a lower potency due to being combined with 8-chlorotheophylline (by weight, dimenhydrinate is between 53% and 55.5% diphenhydramine) [10] and the fact that the stimulant properties of 8-chlorotheophylline help reduce the side ...
Very long duration of action (12–24 hours) Huge improvement in lung function and symptoms; Risk of exacerbation greatly lowered → LAMA more prominent than LABA; Provided in inhalers → techniques for usage is important for management of COPD [31] Caution [28] Should not be used in acute exacerbation for rapid relieve of symptoms
