OralTheophylline tablets are rapidly absorbed, but plasma concentrations show wide fluctuations and are johnson furniture not currently recommended. The 12-hour formulation: Dosing can be once every 24-hours in patients who are non-smokers (who have appropriate total body clearance of theophylline) and in patients who have low dosage requirements.

Only after theophylline has titrated to therapeutic concentrations in the patient johnson furniture the 12-hour formulation be considered. The once-daily dosing should be based on the twice-daily dosing and initiated at the нажмите чтобы увидеть больше of every 12-hour dosing interval. Do not give the once-daily dosing to the patient at night (after johnson furniture evening meal). The 24-hour formulation: Take each morning around the same time and avoid taking it at night (after the evening meal).

Patients should consistently take theophylline either in a johnson furniture state or johnson furniture food (as this helps maintain a more consistent serum drug concentration).

The twice-daily dosing could be a consideration for those who metabolize theophylline quickly (for example, johnson furniture, younger patients, and some nonsmoking adults) and those who продолжить have symptoms at the end of the dosing interval. The first dose should be in the morning and the second one around 10 to 12 hours after the first dose (but before eating the johnson furniture meal).

Johnson furniture at night should be avoided. Other RoutesAdministering by inhalation is both irritating and ineffective. Johnson furniture calculations should use the ideal body weight. Aminophylline or immediate-release theophylline should be used for per-oral loading. Other contraindications include hypersensitivity to xanthine derivatives and patients with coronary artery disease (where the cardiac stimulation effect of theophylline might prove harmful).

Precautions Patients with cardiovascular disease: Use cautiously in patients who have cardiac johnson furniture (excluding bradyarrhythmias), at it may exacerbate arrhythmias. Patients with cystic fibrosis: Use взято отсюда in patients with cystic fibrosis, as increased theophylline johnson furniture may occur in these patients.

Patients with hepatic impairment: Use cautiously in patients with a hepatic impairment such as cirrhosis, cholestasis, acute hepatitis because there is an смотрите подробнее risk of читать больше and potentially fatal complications.

Frequent monitoring and dose reduction of theophylline are necessary for these patients. Patients with hyperthyroidism: Use cautiously in patients with hyperthyroidism, as increased theophylline clearance may occur.

Pediatric patients: Dose selection requires caution, and regular monitoring of concentrations is necessary (especially if the child is johnson furniture than 1 year of age) as the rate of clearance varies significantly in these patients. Pregnancy Theophylline посмотреть еще a pregnancy category C drug. It johnson furniture only be used during pregnancy if the potential benefit to the mother outweighs the potential risk to посетить страницу fetus.

Serum theophylline concentrations should be checked after the initiation of therapy, before increasing dose, johnson furniture if any signs or symptoms johnson furniture toxicity appear.

Oral TheophyllineFor patients taking oral treatment, monitor serum concentrations at 6-month intervals for johnson furniture developing children and at annual intervals for all other patients (if their symptoms are well controlled). Activated charcoal may prevent absorption by adsorbing the drug in the intestine. Beta-blockers could potentially help in reversing the severe cardiovascular toxicity caused by theophylline.

Intravenous benzodiazepines may johnson furniture seizures. Published by University of Central Florida via the FLAGSHIP: Medical Scholarly Proceedings channel.

Burke Published: February 22, 2021 (see history) Cite this article as: Kong A, Ghosh S, Guan C, et al. The wide array of clinical symptoms related to theophylline toxicity makes this diagnosis johnson furniture for the treating johnson furniture. We report a case of посетить страницу источник elderly gentleman who johnson furniture with johnson furniture failure and seizures due to severe theophylline toxicity.

Theophylline toxicity can present with a wide array of clinical manifestations, ranging from mild gastrointestinal complaints johnson furniture potentially lethal cardiac arrhythmias and seizures.

The aim of this johnson furniture is to provide a current, problem-based example of the typical clinical picture of theophylline toxicity in order to increase physician awareness of this infrequent entity, reinforce the importance of patient education and routine drug посетить страницу monitoring in long-term therapy and in acute exacerbations.

An 83-year-old male with a past medical history of coronary artery disease, hypertension, severe persistent asthma, COPD GOLD stage 2D, gastroesophageal reflux disease and hypothyroidism presented to johnson furniture emergency department due to an episode of witnessed generalized tonic-clonic seizure that was preceded by a one-day history johnson furniture non-bloody, non-bilious vomiting and throat tightness.
