¶ Dose reduction and/or serum Theophylline concentration measurement is indicated whenever adverse effects are present, physiologic abnormalities that can reduce Theophylline clearance occur (., sustained fever), or a drug that interacts with Theophylline is added or discontinued (see WARNINGS ).
Once-Daily Dosing: The slow absorption rate of this preparation may allow once-daily administration in adult non-smokers with appropriate total body clearance and other patients with low dosage requirements. Once-daily dosing should be considered only after the patient has been gradually and satisfactorily titrated to therapeutic levels with q12h dosing. Once-daily dosing should be based on twice the q12h dose and should be initiated at the end of the last q12h dosing interval. The trough concentration (C min ) obtained following conversion to once-daily dosing may be lower (especially in high clearance patients) and the peak concentration (C max ) may be higher (especially in low clearance patients) than that obtained with q12h dosing. If symptoms recur, or signs of toxicity appear during the once-daily dosing interval, dosing on the q12h basis should be reinstituted.
It is essential that serum Theophylline concentrations be monitored before and after transfer to once-daily dosing.
Food and posture, along with changes associated with circardien rhythm, may influence the rate of absorption and / or clearance rates of Theophylline from extended-release dosage forms administered at night. The exact relationship of these and other factors to nighttime serum concentrations and the clinical significance of such findings require additional study. Therefore, it is not recommended that Theophylline extended-release once-daily dosing be administered at night.
Konstantinos Vasilis Petrides ("K. V. Petrides") proposed a conceptual distinction between the ability based model and a trait based model of EI and has been developing the latter over many years in numerous publications.   Trait EI is "a constellation of emotional self-perceptions located at the lower levels of personality."  In lay terms, trait EI refers to an individual's self-perceptions of their emotional abilities. This definition of EI encompasses behavioral dispositions and self-perceived abilities and is measured by self report , as opposed to the ability based model which refers to actual abilities, which have proven highly resistant to scientific measurement. Trait EI should be investigated within a personality framework.  An alternative label for the same construct is trait emotional self-efficacy .
