Effects of Theophylline on Plasma Levels of Interleukin-4,Cyclic Nucleotides and Pulmonary Functions in Patients with Chronic Obstructive Pulmonary Disease

Summary: In order to measure the plasma levels of interleukin 4 (IL 4), cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) in patients with chronic obstructive pulmonary disease (COPD) and observe the effects of oral theophylline on them, we divided 28 COPD patients into COPD experimental group and COPD control group. Plasma levels of IL 4, cAMP and cGMP as well as parameters of pulmonary function tests were measured in these 2 groups before and after 2 weeks of treatment with oral theophylline (Protheo, 400 mg, qd) or placebo. Plasma levels of IL 4 and cGMP were significantly elevated in patients with COPD as compared with normal controls ( P <0.05), while cAMP and cAMP/cGMP were significantly lower than those in controls ( P <0.01). Plasma level of IL 4 was inversely correlated with forced expiratory volume at the first second (FEV 1) and with maximum expiratory flow rate at 50 % of forced vital capacity (V 50 ) (both r =-0.46, P <0.05) while it was directly correlated with the scores of the clinical manifestations ( r =0.57, P <0.05) in COPD patients. Two weeks after treatment with theophylline, IL 4 and cGMP in COPD experimental group were decreased significantly while cAMP and cAMP/cGMP increased significantly ( P <0.05). The change of IL 4 was inversely correlated with the changes of FEV 1 and V 50 ( r =-0.53 and -0.54, respectively, P <0.05). Two weeks after placebo treatment, the COPD control group did not show such changes. We are led to conclude that IL 4 might play a role in the pathoge nesis of the airway inflammation and air flow limitation in COPD patients and the mechanisms of theophylline's therapeutic effects of attenuating air flow limitation may partially depend on its anti inflammatory effects on the airways which, in turn, is dependent on its inhibitory effects on some inflammatory mediators such as IL 4.

Quantification of theophylline or paracetamol in milk matrices by high-performance liquid chromatography

A simple, accurate and sensitive high-performance liquid chromatography （HPLC） method was developed, validated and applied to the determination of either theophylline or paracetamol in milk-based samples. The method allowed drug quantification in fresh and powdered milk with a relatively short run time of analysis and it was also successfully applied to the quantification of the drugs in solid dosage forms intended for pediatric use. Moreover, the main significant advantages over other published works are the simplicity of the sample preparation, reduced assay time and sample loss. The method meets the International Conference on Harmonization guideline for analytical methods validation regarding specificity, linearity, accuracy, precision, specificity and robustness as required by health authorities and applied by industry while designing and marketing new drug products. The technique encompasses the separation of the analytes with a reverse phase C18 column under isocrafic conditions and UV detection at 272 nm and 243 nm, respectively, for theophylline and paraeetamol. The lower limit of quantification for both drugs was determined as 0.2 μg/mL and the between-batch accuracy was 99.7%. This HPLC method allows quantification of theophylline and paracetamol in milk matrices and it can be applied in the design, development and production of milk-based pediatric dosage forms.

Delivery of theophylline as dry powder for inhalation

Theophylline(TP)is a very well established orally or intravenously delivered antiasthma drug with many beneficial effects.This study aims to improve asthma treatment by creating a dry powder inhalable(DPI)formulation of TP to be delivered directly to the lung,avoiding the side effects associated with conventional oral delivery.The DPI TP formulation was investigated for its physico-chemical characteristics using scanning electron microscopy,laser diffraction,thermal analysis and dynamic vapour sorption.Furthermore,aerosol performance was assessed using the Multi Stage Liquid Impinger(MSLI).In addition,a Calu-3 cell transport assay was conducted in vitro using a modified ACI to study the impact of the DPI formulation on lung epithelial cells.Results showed DPI TP to be physico-chemically stable and of an aerodynamic size suitable for lung delivery.The aerosolisation performance analysis showed the TP DPI formulation to have a fine particle fraction of 29.70±2.59%(P<0.05)for the TP formulation containing 1.0%(w/w)sodium stearate,the most efficient for aerosolisation.Regarding the deposition of TP DPI on Calu-3 cells using the modified ACI,results demonstrated that 56.14±7.62%of the total TP deposited(13.07±1.69μg)was transported across the Calu-3 monolayer over 180 min following deposition,while 37.05±12.62%of the deposited TP was retained in the cells.This could be due to the presence of sodium stearate in the current formulation that increased its lipophilicity.A DPI formulation of TP was developed that was shown to be suitable for inhalation.

Studies on Thermodynamic Properties of Adsorption of Theophylline by Phenolic Resin Adsorbents

In the present work,the equilibrium adsorption of theophylline was studied by phenolic resin adsorbents: JDW\|2(made by ourselves) and Duolite S\|761 within a temperature range of 303\_323 K. The experimental results show that the Freundlich adsorption law is applicable to the adsorption of theophylline on the two adsorbents,the exponents \%n\%>1 indicate that they are favorable to the adsorptions;the negative values of all the isosteric adsorption enthalpies for the theophylline indicate the exothermic process of the adsorption,while the range(10\_40 kJ/mol) of their magnitudes manifests the physisorption process;other thermodynamic properties,the free energy changes and the entropy change associated with adsorption have been calculated from the Gibbs adsorption equation and the Gibbs\|Helmholtz equation.

Direct Activation of CFTR Chloride Channel by Natural Compound Theophylline

Theophylline has been widely used in the＇treatment of airway disease but molecular mechanism has not been clearly elucidated. Previous studies have manifested that theophylline increases intracellular cAMP concentra- tion. Because cystic fibrosis transmembrane conductance regulator（CFTR） is a cAMP-dependent Cl- channel that plays key roles in fluid secretion in vivo, we postulated that theophylline activates CFTR channel gating. We found （1） theophylline stimulated CFTR-mediated anion transport in a concentration-dependent manner, and CFTR specific blocker completely reversed the effect; （2） theophylline had no effect on △F508 or G551D mutant CFTR chloride channel activity; （3） theophylline had additive effect with forskolin（FSK） and 3-isobutyl-xanthin（IBMX）, thus a direct binding activation mechanism was suggested. In conclusion, the results may provide a clue to elucidating the molecular mechanism of theophylline activities and theophylline may present a novel lead drug in treating CFTR-related disease.

Molecularly Imprinted Polymer for Theophylline Retention and Molecular Recognition Properties in Capillary Electrochromatography

Molecular imprinting of theophylline in poly (methacrylic acid- ethylene dimethacrylate) as CEC stationary phases was synthesized by an in situ photo-initiated polymerization reaction. The effect of electrolyte pH on xanthine derivatives and the stability of MIP column performance were investigated. the relative standard deviation (D RS) of migration time of five consecutive runs on MIP column was in the range of 2.2%–3.1%. The reproducibility of migration time column to column of M(A) was in the range of 3.8%–4.9%. The highest column efficiency was more than 140 000 plates per meter. The MIP capillaries had showed better selective for theophylline, which comparing with the reference column. The urine sample was separated by spiked 5×10?4 mol·L?1 theophylline.

Theophyllineecitric acid co-crystals easily induced by DSCeFTIR microspectroscopy or different storage conditions

A simultaneous differential scanning calorimetryeFourier transform infrared(DSCeFTIR)microspectroscopy was used to quickly investigate the co-crystal formulation between anhydrous theophylline(TP)and anhydrous citric acid(CA)in a one-step procedure.The raw materials of TP andCA,aswell as the intactTPeCA co-crystal prepared by slow solvent evaporation were also respectively examined by this approach.The result indicates that the TPeCA cocrystal formulation was easily induced using this DSCeFTIR technique.The thermaldependent changes in three-dimensional FTIR spectral contour profiles were started from 165
C to induce the co-crystal formation of TPeCA,which was prior to the endothermic peak at 173
C found in the conventional DSC curve.Beyond 165
C,several new IR absorption peaks at 3515,3124,1730,1710,1677,1648,1552 and 1265 cm1 corresponding to unique IR spectral peaks of intact TPeCA co-crystal were observed.The DSCeFTIR microspectroscopic results also evidenced the dimeremonomer transition of CA,but there were no markedly changes for TP or intact TPeCA co-crystal before its fusion.This strongly implies that the DSCeFTIR technique giving spectroscopic and thermodynamic information could simultaneously induce and identify the TPeCA co-crystal formation and phase transition of samples.Different storage conditions affecting the stability of both physical mixture and ground mixture of TPeCA were also determined.The physicalmixture of TPeCA after storing at 55
C/75%RH condition for one day was fast transformed to TPeCA co-crystal,indicating that TPeCA co-crystal was easily induced under accelerated storage condition.While the co-crystal formed from TPeCA ground mixture was stable in both 25
C/75%RH and 55
C/75%RH conditions.

Evaluation of the Controlled Release Ability of Theophylline from Xanthan/Chondroitin Sulfate Hydrogels

The xanthan/chondroitin sulfate (X/CS) hydrogels, obtained by a crosslinking technique, were evaluated in vitro and in vivo as matrices for theophylline release. The influence of pH of simulated physiological media on the X/CS swelling behaviour at 37°C was investigated. The hydrogels theophylline loading degree was evaluated by near infrared chemical imaging (NIR-CI) technique and confirmed also by FT-IR spectroscopy;the drug loading was about 77.5% based on PLS-DA prediction (Partial least squares-Discriminate Analysis). The release profiles of theophylline from X/CS hydrogels in simulated gastric fluid (SGF) and simulated intestinal fluid (SIF) depend on CS content. The release mechanisms were controlled by the drug solubility and ionic properties of the polymers. In vivo theophylline delivery was done by oral administration. Pharmacokinetic analysis revealed sustained-release characteristics for 50/50 X/CS theophylline-loaded formulation compared with raw theophylline which was rapidly absorbed, distributed and eliminated. A good in vitro-in vivo correlation was found.

7-(2-Ethyltiophenyl) Theophylline as Copper Corrosion Inhibitor in 1M HNO₃

7-(2-ethyltiophenyl) theophylline was used as copper corrosion inhibitor in 1M HNO3 solution. The study was performed using mass loss, scanning electron microscopy (SEM) and Density Functional Theory (DFT) methods. The results show that the inhibition efficiency increases up to 91.29% with increase of the inhibitor concentration (from 0.05 to 5 mM) but decreases with raising temperature of the solution. Copper dissolution was found to be temperature and 7-(2-ethyltiophenyl) theophylline concentration dependent. The thermodynamic functions related to the adsorption of the molecule on the copper surface and that of the metal dissolution were determined. The results point out a spontaneous adsorption and an endothermic dissolution processes. Adsorption models including Langmuir, El-Awady and Flory-Huggins isotherms were examined. The results also suggest spontaneous and predominant physical adsorption of 7-(2-ethyltiophenyl) theophylline on the metal surface which obeys Langmuir isotherm model. Further investigation on the morphology using scanning electron microscopy (SEM) has confirmed the existence of a protective film of inhibitor molecules on copper surface. Furthermore, the global and local reactivity parameters of the studied molecule were analyzed. Experimental and theoretical results were found to be in good agreement.

Effects of theophylline/chitosan/β-cyclodextrin microspheres for oral drug delivery on an asthmatic rat model

Objective:This study aimed to investigate the effects of TH/CTS/β-CD microspheres by oral administration on ovalbumin allergic asthma of a rat model.Methods:Spray drying method was applied for preparing the TH/CTS/β-CD microspheres,which were used in treatment of asthmatic rats.At a predetermined time,the levels of eosinophil(Eos),protein,lactate dehydrogenase(LDH),aspartate transaminase(AST),glutamic pyruvic transaminase(GPT),and creatinine(Cr)were ascertained by automatic hematology and biochemical analyzers.Lung tissue histology was performed by hematoxylin-eosin staining.Results:No significant differences were found about the contents of Eos in the blood,and the contents of Eos,protein and LDH in the bronchoalveolar lavage fluid between the microsphere-treated and dexamethasone-treated groups,but the levels were lower in both treated groups than in the model group.In the microsphere-treated group,the levels of Cr,AST,and GPT in the serum of rats showed no significant differences compared with the normal group.Based on lung histopathological findings,the microspheres attenuated inflammatory cell infiltration and mucus hypersecretion compared with the model group.Conclusion:This study demonstrated that TH/CTS/β-CD microspheres exerted an anti-inflammatory effect and could serve as a novel promising drug delivery system for asthma treatment.

Determination of theophylline concentration in serum by chemiluminescent immunoassay

Objective: This study aimed to establish chemiluminescent immunoassay (CLIA) for quantitative determination of theophylline levels in human serum. Methods: To measure the concentration of theophylline (n=122) and evaluate the assay.Results: The linear range of the CLIA method was 0.51～40 mg/L (Y=1.02X+0.44, r=0.995).

Conclusion: This method is simple, convenient and precise for clinical pharmacokinetics study oftheophylline.

The molecular mechanisms of plasticity in crystal forms of theophylline

Plastic and elastic behaviors of organic crystals have profound influence on the processability of pharmaceutical substances.Analogous to metals,the identifications of molecular slip planes in organic crystals are regarded as a strategy for harnessing plasticity.In this work,we experimentally characterized the form II anhydrous theophylline(THPa)and its monohydrate(THPm)for their distinct plastic and elastic behaviors.Extensive DFT calculations were performed to model the effects of increasing lattice strains on molecular packing.We discovered that the energy barrier associated with the strain-induced molecular rearrangement would link to the plasticity of THPa,and possibly other simple aromatic compounds.Meanwhile,water molecules in THPm disrupt the stacking architecture from THPm and effectively undermine the general mechanism for plasticity.Hydrate formation would therefore be an alternative strategy to engineer the mechanical property of organic crystalline materials.

Effect of chronic intermittent hypoxia on theophylline metabolism in mouse liver

Background Chronic intermittent hypoxia （CIH） has been associated with abnormalities in the liver, which is the most important organ for drug metabolism. This study aimed to investigate the effect of CIH on theophylline metabolism in mouse liver. Methods Eight C57BL/6J mice were exposed to CIH for 12 weeks. Eight C57BL/6J mice were exposed to room air as a control group. Serum levels of alanine aminotransferase and aspartate aminotransferase were measured. Liver histology was observed by light and electron microscopy. Total hepatic cytochrome P450 concentration was measured. Hepatocytes were isolated and incubated with 15 mg/ml theophylline for four hours. After incubation, the theophylline concentration in the supernatant was measured and the theophylline metabolism rate was calculated. Results CIH did not affect the serum transaminase levels. Livers from mice exposed to CIH showed hepatocellular edema, and liver cells had fuzzy rough endoplasmic reticulum under the electron microscope. The theophylline metabolism rate was significantly inhibited by CIH compared with controls; （16.60±2.43）% vs. （21.58±4.52）% （P=0.02）. The total liver cytochrome P450 concentration in the CIH group was significantly lower than in the control group; （0.83±0.08） vs. （1.13±0.21）mol/mg microsomal protein （P=0.004）. Conclusion CIH decreases theophylline metabolism by mouse hepatocytes, which may correlate with the downregulation of cytochrome P450 expression by CIH.

The effect of theophylline on sleep-disordered breathing in patients with stable chronic congestive heart failure

Objective To determine the prevalence of sleep-disordered breathing in patients with stable, optimally treated chronic congestive heart failure and the effect of short-term oral theophylline therapy on periodic breathing in these patients.Methods Patients with stable, optimally treated chronic congestive heart failure were monitored by polysomnography during nocturnal sleep. The effects of theophylline therapy on periodic breathing associated with stable heart failure were observed before and after treatment.Results Patients were divided into two groups. Group Ⅰ (n =21) consisted of individuals with 15 episodes of apnea and hypopnea [as determined by the apnea-hypopnea index (AMI) ] per hour or less; Group Ⅱ (n =15, 41.7%) individuals had an index of more than 15 episodes per hour. In group Ⅱ , the AHI varied from 16. 8 to 78. 8 (42. 6 ±+15. 5) in which the obstructive AHI was 11.1 ± 8. 4 and the central AHI was 31. 5 ±9.6. Group Ⅱ had significantly more arousals (36. 8 ±21. 3 compared with 19.4 ±11.2 in group Ⅰ) that were directly attributable to episodes of apnea and hypopnea, lower arterial oxyhemoglobin saturation (76. 7% ±4. 6% compared with 86. 5% ±2. 8%) and lower left ventricular ejection fraction (24. 2% ±8. 8% compared with 31. 5%±10. 6%). Thirteen patients with compensated heart failure and periodic breathing received theophylline orally (at an average dose of 4. 3 mg/kg) for five to seven days. After treatment, the mean plasma theophylline concentration was (11. 3±2. 5) μg/ml. Theophylline therapy resulted in significant decreases in the number of AHI (20. 8±13. 2 vs. 42. 6±15. 5; P < 0. 001) and the number of episodes of central apnea-hypopnea per hour (10.1 ±7. 6 vs. 31. 5±9. 6; P<0. 001). Furthermore, the percentage of total sleep time during which arterial oxyhemoglobin saturation (SaO2) was less than 90 percent (8. 8%±8. 6% vs. 23. 4% ±24.1%; P<0. 05) and the arousals per hour (18. 7 ±21. 2 vs. 36. 8 ±21. 3; P<0. 05) were also lower. There were no significant differences in the characteristics of sleep or obstructive AHI before and after theophylline treatment.Conclusions The prevalence of sleep-disordered breathing (mainly periodic respiration or cheyne-stokes respiration with central sleep apnea) is high in patients with stable chronic congestive heart failure. The sleep-disordered breathing episodes are associated with severe nocturnal arterial blood oxyhemoglobin desaturation and excessive arousals. In these patients, oral theophylline therapy may reduce the number of episodes of central apnea and hypopnea and the duration of arterial oxyhemoglobin desaturation during nocturnal sleep.
