Theophyllines may also produce transiently increased urinary frequency, dehydration, twitching of fingers and hands, tachypnea, and elevated serum AST (SGOT) concentrations. Hypersensitivity reactions characterized by urticaria, generalized pruritus, and angioedema have been reported with aminophylline administration. A contact-type dermatitis, caused by hypersensitivity to the ethylenediamine component of aminophylline, has also been reported. Bone marrow suppression, leukopenia, thrombocytopenia, and hemorrhagic diathesis have also been reported, but their association with theophylline therapy is questionable. Other adverse effects of theophyllines include albuminuria, increased urinary excretion of renal tubular cells and erythrocytes, hyperglycemia, and syndrome of inappropriate secretion of antidiuretic hormone (SIADH). /Theophyllines/

Theophyllines produce GI irritation and CNS stimulation following administration by any route. Theophyllines are all somewhat irritating to gastric mucosa; the importance of reported differences among the individual agents is doubtful. The most common adverse GI effects (both locally and centrally mediated) include nausea, vomiting, epigastric pain, abdominal cramps, anorexia, and, rarely, diarrhea. Hematemesis has also occurred. Adverse CNS effects, which are often more severe in children than in adults, include headache, irritability, restlessness, nervousness, insomnia, dizziness, reflex hyperexcitability, and seizures. Reduction of theophylline dosage usually reduces the incidence and severity of adverse gastric and CNS effects; however, if these adverse effects persist, the drug may have to be withdrawn. The drugs may be administered orally before or after meals, with a full glass of liquid, or with antacids to minimize locally mediated GI irritation. /Theophyllines/

Absorption
Theophylline is rapidly and completely absorbed after oral administration in solution or immediate-release solid oral dosage form.
Route of Elimination
Theophylline does not undergo any appreciable pre-systemic elimination, distributes freely into fat-free tissues and is extensively metabolized in the liver. 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.

Dissolution appears to be the rate-limiting step in the absorption of oral theophylline. Under the acidic conditions of the stomach, the theophylline salts and compounds release free theophylline. ... Microcrystalline dosage forms and oral solutions of theophyllines are absorbed more rapidly, but not to a greater extent, than are uncoated tablets. Although the rate of absorption is slower, extended-release preparations (capsules and tablets) of theophylline are generally absorbed to the same extent as uncoated tablets; however, the actual rate of absorption of extended-release preparations may differ. Extended-release preparations of theophyllines have been formulated to release the drug at various rates suitable for dosing every 8-12, 12, or 24 hours; however, the actual dosing frequency for a given patient depends on their individual pharmacokinetic parameters. Since the rate and extent of absorption may differ between various extended-release preparations and sometimes between different dosage sizes of the same preparation, patients should generally be stabilized on a given preparation; substitution of one extended-release preparation for another should generally only be made when the preparations have been shown to be equivalent and/or the patient is evaluated pharmacokinetically during the transition period. Absorption of theophyllines may also be delayed, but is generally not reduced, by the presence of food in the GI tract; however, the effect of food on the absorption of extended-release preparations appears to be variable, and the manufacturer's recommendations for administration of specific preparations should be followed.

IV theophylline produces the highest and most rapid serum theophylline concentration. ... Slightly lower or equal peak serum concentrations are reached after oral administration of equal amounts of theophylline in uncoated tablet, capsule, or liquid formulations. Following oral administration of theophylline capsules or uncoated tablets, peak serum concentrations are usually reached in 1-2 hours. Peak serum theophylline concentrations are usually obtained after about 1 hour when theophylline oral solutions or microcrystalline tablets are administered. Enteric-coated theophylline tablets produce variable serum concentrations which usually peak at about 5 hours. Single doses of extended-release theophylline capsules or tablets usually produce peak serum concentrations after 4 hours, but commercial products vary in their rates and completeness of absorption. Extended-release theophylline preparations are generally associated with relatively small fluctuations in steady-state peak and trough serum concentration; however, clinically important steady-state peak-trough differences may occur in individuals who rapidly eliminate theophylline. Theophylline retention enemas usually produce peak serum concentrations in 1-2 hours. Serum theophylline concentrations generally have been apparent 3-5 hours after administration of the drug as rectal suppositories (no longer commercially available in the US).

Hepatic. Biotransformation takes place through demethylation to 1-methylxanthine and 3-methylxanthine and hydroxylation to 1,3-dimethyluric acid. 1-methylxanthine is further hydroxylated, by xanthine oxidase, to 1-methyluric acid. About 6% of a theophylline dose is N-methylated to caffeine. Caffeine and 3-methylxanthine are the only theophylline metabolites with pharmacologic activity.
Both the N-demethylation and hydroxylation pathways of theophylline biotransformation are capacity-limited. Due to the wide intersubject variability of the rate of theophylline metabolism, non-linearity of elimination may begin in some patients at serum theophylline concentrations <10 ug/mL. Since this non-linearity results in more than proportional changes in serum theophylline concentrations with changes in dose, it is advisable to make increases or decreases in dose in small increments in order to achieve desired changes in serum theophylline concentrations. Accurate prediction of dose-dependency of theophylline metabolism in patients a priori is not possible, but patients with very high initial clearance rates (i.e., low steady-state serum theophylline concentrations at above average doses) have the greatest likelihood of experiencing large changes in serum theophylline concentration in response to dosage changes.

Caffeine and 3-methylxanthine are the only theophylline metabolites with pharmacologic activity. 3-methylxanthine has approximately one tenth the pharmacologic activity of theophylline and serum concentrations in adults with normal renal function are <1 ug/mL. In patients with end-stage renal disease, 3-methylxanthine may accumulate to concentrations that approximate the unmetabolized theophylline concentration. Caffeine concentrations are usually undetectable in adults regardless of renal function. In neonates, caffeine may accumulate to concentrations that approximate the unmetabolized theophylline concentration and thus, exert a pharmacologic effect.

Theophylline is metabolized by the liver to 1,3-dimethyluric acid, 1-methyluric acid, and 3-methylxanthine. ... Individuals metabolize theophylline at different rates; however, individual metabolism of the drug is generally reproducible. Theophylline and its metabolites are excreted mainly by the kidneys. Renal clearance of the drug, however, contributes only 8-12% of the overall plasma clearance of theophylline. Small amounts of theophylline are excreted in feces unchanged.

Unchanged theophylline (35% of urinary radioactivity) and 1,3-dimethyluric acid (34%) are the main compounds excreted in urine, followed by 1-methyluric acid (18%), 3-methylxanthine (3%) and unidentified polar metabolites (4.8%). Theophylline metabolism was impaired in rats at day 18 of gestation, as shown by increased excretion of theophylline (73%); this was explained by a decreased formation of 1,3-dimethyluric acid (-68%) and 1-methyluric acid (-30%). Essentially similar results were obtained with pregnant baboons. Each animal species is characterized by differences in the profile of the metabolites recovered in urine; in addition, quantitative differences in theophylline metabolic pathways were seen even in different strains of mice.

In maintenance-dose theophylline schedules, serum concentrations among patients vary at least sixfold and serum half-lives exhibit wide interpatient variation because of differences in rate of metabolism. Serum half lives ranges from about 3-12.8 (average 7-9) hours in otherwise healthy, nonsmoking asthmatic adults, from about 1.5-9.5 hours in children, and from about 15-58 hours in premature infants. ... When compared with that of otherwise healthy, nonsmoking asthmatic adults, the serum half life of theophylline may be increased and total body clearance decreased in patients with congestive heart failure, chronic obstructive pulmonary disease, cor pulmonale, or liver disease, and in geriatric patients. In cigarette and/or marijuana smokers, theophylline serum half life averages 4-5 hours and total body clearance is increased compared with nonsmokers.

Theophylline is distributed rapidly within the body, and plasma half-times were 5.7-11.5 hr in dogs, 11 hr in pigs, 7.8 hr in cats, 3.8-5.5 hr in rabbits and 1.2-4 hr in rats. At higher doses, rats had longer half-times probably because of a combination of increased diuresis and saturation of the metabolism.

Theophylline relaxes the smooth muscle of the bronchial airways and pulmonary blood vessels and reduces airway responsiveness to histamine, methacholine, adenosine, and allergen. Theophylline competitively inhibits type III and type IV phosphodiesterase (PDE), the enzyme responsible for breaking down cyclic AMP in smooth muscle cells, possibly resulting in bronchodilation. Theophylline also binds to the adenosine A2B receptor and blocks adenosine mediated bronchoconstriction. In inflammatory states, theophylline activates histone deacetylase to prevent transcription of inflammatory genes that require the acetylation of histones for transcription to begin.
Theophylline is an old drug experiencing a renaissance owing to its beneficial antiinflammatory effects in chronic respiratory diseases, such as asthma and chronic obstructive pulmonary disease. Multiple modes of antiinflammatory action have been reported, including inhibition of the enzymes that degrade cAMP-phosphodiesterase (PDE). Using primary cultures of airway smooth muscle (ASM) cells, we recently revealed that PDE4 inhibitors can potentiate the antiinflammatory action of beta2-agonists by augmenting cAMP-dependent expression of the phosphatase that deactivates mitogen-activated protein kinase (MAPK)-MAPK phosphatase (MKP)-1. Therefore, the aim of this study was to address whether theophylline repressed cytokine production in a similar, PDE-dependent, MKP-1-mediated manner. Notably, theophylline did not potentiate cAMP release from ASM cells treated with the long-acting beta2-agonist formoterol. Moreover, theophylline (0.1-10 uM) did not increase formoterol-induced MKP-1 messenger RNA expression nor protein up-regulation, consistent with the lack of cAMP generation. However, theophylline (at 10 uM) was antiinflammatory and repressed secretion of the neutrophil chemoattractant cytokine IL-8, which is produced in response to TNF-a. Because theophylline's effects were independent of PDE4 inhibition or antiinflammatory MKP-1, we then wished to elucidate the novel mechanisms responsible. We investigated the impact of theophylline on protein phosphatase (PP) 2A, a master controller of multiple inflammatory signaling pathways, and show that theophylline increases TNF-a-induced PP2A activity in ASM cells. Confirmatory results were obtained in A549 lung epithelial cells. PP2A activators have beneficial effects in ex vivo and in vivo models of respiratory disease. Thus, our study is the first to link theophylline with PP2A activation as a novel mechanism to control respiratory inflammation.

Theophylline has two distinct actions in the airways of patients with reversible obstruction; smooth muscle relaxation (i.e., bronchodilation) and suppression of the response of the airways to stimuli (i.e., non-bronchodilator prophylactic effects). While the mechanisms of action of theophylline are not known with certainty, studies in animals suggest that bronchodilatation is mediated by the inhibition of two isozymes of phosphodiesterase (PDE III and, to a lesser extent, PDE IV) while non-bronchodilator prophylactic actions are probably mediated through one or more different molecular mechanisms, that do not involve inhibition of PDE III or antagonism of adenosine receptors. Some of the adverse effects associated with theophylline appear to be mediated by inhibition of PDE III (e.g., hypotension, tachycardia, headache, and emesis) and adenosine receptor antagonism (e.g., alterations in cerebral blood flow). Theophylline increases the force of contraction of diaphragmatic muscles. This action appears to be due to enhancement of calcium uptake through an adenosine-mediated channel.

Lung deflation and inflation during cardiac surgery with cardiopulmonary bypass contributes to pulmonary dysfunction postoperatively. Theophylline treatment for lung diseases has traditionally been thought to act by phosphodiesterase inhibition; however, increasing evidence has suggested other plausible mechanisms. We investigated the effects of deflation and reinflation on signaling pathways (p38-mitogen-activated protein kinase [MAPK], extracellular signal-regulated kinase 1 and 2 [ERK1/2], and Akt) and whether theophylline influences the deflation-induced lung injury and associated signaling. Isolated rat lungs were perfused (15 mL/min) with deoxygenated rat blood in bicarbonate buffer and ventilated. After 20 minutes' equilibration, the lungs were deflated (60 minutes, aerobic perfusion 1.5 mL/min), followed by reinflation (60 minutes, anaerobic reperfusion 15 mL/min). Compliance, vascular resistance, and kinase phosphorylation were assessed during deflation and reinflation. The effects of SB203580 (50 uM), a p38-MAPK inhibitor, and theophylline (0.083 mM [therapeutic] or 3 mM [supratherapeutic]) on physiology and signaling were studied. Deflation reduced compliance by 44% compared with continuously ventilated lungs. p38-MAPK and Akt phosphorylation increased (three to fivefold) during deflation and reinflation, and ERK1/2 phosphorylation increased (approximately twofold) during reinflation. SB203580 had no effect on lung physiology or ERK1/2 and Akt activation. Both theophylline doses increased cyclic adenosine monophosphate, but only 3 mM theophylline improved compliance. p38-MAPK phosphorylation was not affected by theophylline; 0.083 mM theophylline inhibited reinflation-induced ERK1/2 phosphorylation (72% + or - 3%); and 3 mM theophylline inhibited Akt phosphorylation during deflation (75% + or - 5%) and reinflation (87% + or - 4%). Lung deflation and reinflation stimulates differential p38-MAPK, ERK1/2, and Akt activation, suggesting a role in lung injury during cardiopulmonary bypass. However, p38-MAPK was not involved in the compromised compliance. A supratherapeutic theophylline dose protected lungs against deflation-induced injury and was associated with inhibition of phosphoinositide 3-kinase/Akt rather than phosphodiesterase.

Theophylline and aminophylline have been widely used as inhibitors of phosphodiesterase when examining the role of cAMP in regulating cell function. In reality, however, these phosphodiesterase inhibitors may have additional sites of action that could complicate the interpretation of the results. These additional sites of action could include antagonism of inhibitory adenosine autoreceptors and release of intracellular calcium. The purpose of the present study was to determine which of the above three is the primary mechanism by which theophylline and aminophylline affect transmitter release at the mammalian neuromuscular junction. Quantal release measurements were made using intracellular recording techniques. A variety of drugs were used to elucidate this pathway. Isoproterenol, an adenylate cyclase activator, was first used to establish the effect of enhanced levels of cAMP. Theophylline application on its own or in the presence of a drug combination that blocked the adenosine receptor and phosphodiesterase pathways caused significant release depression, opposite to what is expected if it was functioning to enhance cAMP levels. However, when applied in the presence of a drug combination that blocked the adenosine receptor, phosphodiesterase and intracellular ryanodine calcium pathways, theophylline was unable to depress release. Therefore, it was concluded that the major mechanism of action of theophylline is depression of transmitter release by causing the release of intracellular calcium. Aminophylline application alone resulted in a significant enhancement of release. However, when coupled with an adenosine receptor blocker, the ability of aminophylline to enhance transmitter release was blocked, suggesting that its dominant mechanism of action is adenosine receptor inhibition. Taken together, these results indicate that the use of theophylline and aminophylline is inappropriate when examining the role of cAMP at the mammalian neuromuscular junction.
