Mepolizumab Nucala is administered subcutaneously, and reslizumab Cinqair is administered intravenously.

Congestive Heart Failure CHF: Theophylline clearance is decreased by 50% or more in patients with CHF. The extent of reduction in Theophylline clearance in patients with CHF appears to be directly correlated to the severity of the cardiac disease.

For a given population there is no single Theophylline dose that will provide both safe and effective serum concentrations for all patients. Administration of the median Theophylline dose required to achieve a therapeutic serum Theophylline concentration in a given population may result in either sub-therapeutic or potentially toxic serum Theophylline concentrations in individual patients.

What is theophylline

Treatment of Cardiac Arrhythmias. Case reports of Theophylline overdose in humans and animal studies suggest that phenytoin is ineffective in terminating Theophylline-induced seizures. The doses of benzodiazepines and phenobarbital required to terminate Theophylline-induced seizures are close to the doses that may cause severe respiratory depression or respiratory arrest; the healthcare professional should therefore be prepared to provide assisted ventilation. Elderly patients and patients with COPD may be more susceptible to the respiratory depressant effects of anticonvulsants. Barbiturate-induced coma or administration of general anesthesia may be required to terminate repetitive seizures or status epilepticus. General anesthesia should be used with caution in patients with Theophylline overdose because fluorinated volatile anesthetics may sensitize the myocardium to endogenous catecholamines released by Theophylline. Enflurane appears less likely to be associated with this effect than halothane and may, therefore, be safer. Neuromuscular blocking agents alone should not be used to terminate seizures since they abolish the musculoskeletal manifestations without terminating seizure activity in the brain.

Side effects of theophylline

What should I discuss with my healthcare provider before taking theophylline? Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. The clearance of theophylline is very low in neonates see . Theophylline clearance reaches maximal values by one year of age, remains relatively constant until about 9 years of age and then slowly decreases by approximately 50% to adult values at about age 16. Renal excretion of unchanged theophylline in neonates amounts to about 50% of the dose, compared to about 10% in children older than three months and in adults.

Elderly patients are at significantly greater risk of experiencing serious toxicity from theophylline than younger patients due to pharmacokinetic and pharmacodynamic changes associated with aging. Theophylline clearance is reduced in patients greater than 60 years of age, resulting in increased serum theophylline concentrations in response to a given theophylline dose. Protein binding may be decreased in the elderly resulting in a larger proportion of the total serum theophylline concentration in the pharmacologically active unbound form. Elderly patients also appear to be more sensitive to the toxic effects of theophylline after chronic overdosage than younger patients.
