0000014113 00000 n The efficacy of COMBIVENT RESPIMAT is likely to be due to a local effect on the muscarinic and beta2-adrenergic receptors in the lung. Patients with narrow-angle glaucoma, symptomatic. Safety and efficacy of additional doses of COMBIVENT RESPIMAT beyond six inhalations in 24 hours have not been studied. Wt. In studies without a positive control, ipratropium bromide did not alter pupil size, accommodation or visual acuity. There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Ipratropium Bromide And Albuterol in women who are pregnant. 0000038560 00000 n Alcohol-Ipratropium Bromide And Albuterol interaction has not been established. The COMBIVENT RESPIMAT cartridge is provided as an aluminum cylinder with a tamper protection seal on the cap. 163 0 obj <>stream Long term chronic use safety data for COMBIVENT RESPIMAT were obtained from one 48-week, randomized, multi-center, open-label, parallel-group trial that compared COMBIVENT RESPIMAT (20/100 mcg), CFC-propelled COMBIVENT Inhalation Aerosol (36/206 mcg) and the free combination of ipratropium bromide (34 mcg) and albuterol (180 mcg) HFA inhalation aerosols administered 4 times a day in 465 adult COPD patients (273 males and 192 females) 40 years of age and older. 0000009300 00000 n Electrocardiographic changes and/or hypokalemia associated with diuretics may worsen with concomitant use of beta-agonists. Ipratropium 0.5 mg/albuterol 2.5 mg (usually given once). An 18-month study in mice at dietary doses up to 500 mg/kg/day (approximately 2800 times the MRHDID on a mg/m basis) and a 99-week study in hamsters at oral doses up to 50 mg/kg/day (approximately 470 times the MRHDID on a mg/m basis) revealed no evidence of tumorigenicity. The overall incidence and nature of adverse reactions observed were similar to the adverse reactions seen with COMBIVENT RESPIMAT 20/100 mcg. WikiDoc does not promote the administration of any medication or device that is not consistent with its labeling. hTOO |9jV,L+dJ[x {cl F0`!\4 G(XvZ74h_ Y7F*?>. )Y5!l#FRnDh* _ggi_'q_Duajbz^2(C!S. Data from 1424 patients were used in the efficacy analyses. Pharmacokinetic drug-drug interaction between ipratropium bromide and albuterol sulfate was evaluated in a crossover study in 12 healthy male volunteers who received CFC-propelled COMBIVENT Inhalation Aerosol and the two active components separately as individual treatments. Ipratropium bromide is an anticholinergic (parasympatholytic) agent which, based on animal studies, appears to inhibit vagally mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released at the neuromuscular junctions in the lung. Two-year oral carcinogenicity studies in rats and mice have revealed no carcinogenic activity at doses up to 6 mg/kg/day (approximately 400 and 200 times the maximum recommended human daily inhalation dose of ipratropium bromide (MRHDID) in adults on a mg/m basis, respectively). Dialysis is not appropriate treatment for overdosage of albuterol as an inhalation aerosol; the judicious use of a cardiovascular beta-receptor blocker, such as metoprolol tartrate may be indicated. <]/Prev 472063>> Patients should be instructed that if they find that treatment with COMBIVENT RESPIMAT becomes less effective for symptomatic relief, their symptoms become worse, and/or they need to use the product more frequently than usual, medical attention should be sought immediately. Inform patients that COMBIVENT RESPIMAT can produce paradoxical bronchospasm that can be life-threatening. 0000007440 00000 n None was observed at less than MRHDID in adults (on a mg/m2 basis at a maternal dose of 0.025 mg/kg/day). Use of albuterol, a beta-adrenergic agonist, may be associated with the following: The safety data described in Table 1 below are derived from one 12-week, randomized, multi-center, double-blind, double-dummy, parallel-group trial that compared COMBIVENT RESPIMAT (20/100 mcg), CFC-propelled COMBIVENT Inhalation Aerosol (36/206 mcg), and ipratropium bromide delivered by the RESPIMAT inhaler (20 mcg) administered four times a day in 1460 adult COPD patients (955 males and 505 females) 40 years of age and older. 0000037048 00000 n |sort=Label Page In this trial, COMBIVENT RESPIMAT (20/100 mcg) was shown to be clinically comparable (statistically non-inferior) to CFC-propelled COMBIVENT Inhalation Aerosol (36/206 mcg). 0000037347 00000 n While it is recognized that beta2-adrenergic receptors are the predominant receptors on bronchial smooth muscle, recent data indicate that there is a population of beta2-receptors in the human heart which comprise between 10% and 50% of cardiac beta-adrenergic receptors. |?Pill Ingred In general, there were no marked differences between the proportion of patients with adverse reactions for the COMBIVENT RESPIMAT and CFC-propelled COMBIVENT Inhalation Aerosol treated patients. When the labeled number of metered actuations (120) has been dispensed from the inhaler, the RESPIMAT locking mechanism will be engaged and no more actuations can be dispensed. The study was supportive, particularly for safety. Simultaneous administration of both an anticholinergic (ipratropium bromide) and a beta2-sympathomimetic (albuterol sulfate) is designed to produce a greater bronchodilator effect than when either drug is utilized alone at its recommended dosage. There is limited information regarding IV Compatibility of Ipratropium Bromide And Albuterol in the drug label. Non-inferiority was declared if the lower bound of the 95% confidence interval for the point estimate for the difference of COMBIVENT RESPIMAT minus the comparator was more than -50 mL. The action of COMBIVENT RESPIMAT should last 4 to 5 hours or longer. (C13H21NO3)2H2SO4 albuterol sulfate Mol. There were three primary efficacy variables: (i) Mean FEV1 over 0 to 6 hours post-dose defined as the AUC of the change from test-day baseline in FEV1 over 0 to 6 hours post-dose divided by 6 hours (FEV1 AUC0-6h); (ii) Mean FEV1 over 0 to 4 hours post-dose defined as the AUC of the change from test-day baseline in FEV1 over 0 to 4 hours post-dose divided by 4 hours (FEV1 AUC0-4h), and (iii) Mean FEV1 over 4 to 6 hours post-dose defined as the AUC of the change from test-day baseline in FEV1 over 4 to 6 hours post-dose divided by 2 hours (FEV1 AUC4-6h). The steady state systemic exposure obtained for ipratropium bromide following COMBIVENT RESPIMAT was comparable to that of CFC-propelled COMBIVENT Inhalation Aerosol. 0000037641 00000 n There is limited information regarding Ipratropium Bromide And Albuterol Look-Alike Drug Names in the drug label. Ipratropium bromide is an anticholinergic bronchodilator chemically described as 8-azoniabicyclo[3.2.1] octane, 3-(3-hydroxy-1-oxo-2-phenylpropoxy)-8-methyl-8-(1-methylethyl)-, bromide monohydrate, (3-endo, 8-syn)-: a synthetic quaternary ammonium compound chemically related to atropine. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. |format=template 0000036857 00000 n Patients should also be advised that should any combination of these symptoms develop, they should consult their physician immediately. In the 12-week trial in COPD, 48% of COMBIVENT RESPIMAT clinical trial patients were 65 years of age or over. Albuterol has been shown in most clinical trials to have more bronchial smooth muscle relaxation effect than isoproterenol at comparable doses while producing fewer cardiovascular effects. Embryotoxicity was observed as increased resorption in rats at oral doses approximately 6100 times MRHDID in adults (on a mg/m2 basis at maternal doses of 90 mg/kg/day and above). 0000037748 00000 n 0000035987 00000 n Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Anticholinergics prevent the increases in intracellular concentration of Ca++ which is caused by interaction of acetylcholine with the muscarinic receptors on bronchial smooth muscle. 0000036075 00000 n |mainlabel=- Ipratropium plasma AUC and total amount of drug excreted unchanged in urine (Ae) ratios for COMBIVENT RESPIMAT/ CFC-propelled COMBIVENT Inhalation Aerosol were 1.04 and 1.18, respectively. 0000035810 00000 n 0000037594 00000 n 0000036704 00000 n Safety and effectiveness of COMBIVENT RESPIMAT in pediatric patients have not been established. 0000019936 00000 n Instructions for Use is supplied as a tear-off following the full prescribing information. If not used for more than 21 days, patients are to actuate the inhaler until an aerosol cloud is visible and then repeat the process three more times to prepare the inhaler for use. [1]; Associate Editor(s)-in-Chief: Vignesh Ponnusamy, M.B.B.S. |?Label Name In vitro studies and in vivo pharmacology studies have demonstrated that albuterol has a preferential effect on beta2-adrenergic receptors compared with isoproterenol. Consistent with CFC-propelled COMBIVENT Inhalation Aerosol (36/206 mcg), patients receiving COMBIVENT RESPIMAT (20/100 mcg) aged 65 years and over had higher steady state systemic exposures than patients aged under 65 years for both ipratropium (AUC = 166 vs. 105 pghr/mL, Cmax = 38.5 vs. 30.1 pg/mL) and albuterol (AUC = 5.44 vs. 3.27 nghr/mL, Cmax = 1.19 vs. 0.74 ng/mL). |?Drug Name Test-day baseline was the FEV1 recorded prior to inhaling the dose of randomized treatment on test day. The efficacy of COMBIVENT RESPIMAT (20/100 mcg) was evaluated in COPD patients in one randomized, double-blind, double-dummy parallel group trial. 0000037000 00000 n [2]. Common adverse reactions include upper respiratory infection, nasopharyngitis, cough, bronchitis, headache, and dyspnea. 0000036285 00000 n The patients were randomized to one of the following active treatments COMBIVENT RESPIMAT (20/100 mcg) (n=486), CFC-propelled COMBIVENT Inhalation Aerosol (36/206 mcg) (n=491), and ipratropium bromide delivered by the RESPIMAT (20 mcg) (n=483) administered four times a day. There is limited information regarding Chronic Overdose of Ipratropium Bromide And Albuterol in the drug label. 0000036550 00000 n 0000001736 00000 n These studies demonstrated no evidence of teratogenic effects as a result of ipratropium bromide. The median time to onset of bronchodilation, defined as an FEV1 increase of 15% or greater from test-day baseline, for the COMBIVENT RESPIMAT (20/100 mcg) group occurred at 13 minutes post-dose on Day 1. Immune system disorders: hypersensitivity; Investigations: Musculoskeletal and connective tissue disorders: muscular weakness, Psychiatric disorders: CNS stimulation, mental disorder, Respiratory, thoracic, and mediastinal disorders: throat irritation, paradoxical. Albuterol is longer acting than isoproterenol in most patients because it is not a substrate for the cellular uptake processes for catecholamines, nor for metabolism by catechol-O-methyl transferase. 0000019375 00000 n Keep out of reach of children. However, cough occurred more frequently in patients enrolled in the COMBIVENT RESPIMAT group (7.0%) compared to those in the CFC-propelled COMBIVENT Inhalation Aerosol (2.6%) or the free combination of ipratropium bromide and albuterol HFA inhalation aerosols (3.9%) groups. xref COMBIVENT RESPIMAT is indicated for use in patients with COPD on a regular aerosol bronchodilator who continue to have evidence of bronchospasm and who require a second bronchodilator. The FEV1 AUC0-4h for COMBIVENT RESPIMAT (20/100 mcg), was superior to that of ipratropium bromide [LS mean (mL) (95% CI) of the treatment difference was 47 mL (28, 66)] and the mean FEV1 AUC4-6h for COMBIVENT RESPIMAT (20/100 mcg) was non-inferior to that of ipratropium bromide [LS mean (mL) (95% CI) of the treatment difference was -17 (-39, 5)]. 0000036752 00000 n This effect is not considered relevant to human use due to the large doses at which it was observed and the difference in route of administration. Oral reproduction studies were performed in mice, rats and rabbits at doses approximately 340, 68,000 and 17,000 times, respectively, the maximum recommended human daily inhalation dose (MRHDID) in adults (on a mg/m2 basis at maternal doses in each species of 10, 1000 and 125 mg/kg/day, respectively). The clear base is removed to insert the cartridge. The three primary efficacy comparisons were: (i) Non-inferiority of COMBIVENT RESPIMAT (20/100 mcg) to CFC-propelled COMBIVENT Inhalation Aerosol (36/206 mcg) for the FEV1 AUC0-6h on Test Day 85; (ii) Superiority of COMBIVENT RESPIMAT (20/100 mcg) to ipratropium RESPIMAT (20 mcg) for the FEV1 AUC0-4h on Test Day 85, to demonstrate the contribution of albuterol in the combination product, and (iii) Non-inferiority of COMBIVENT RESPIMAT (20/100 mcg) in comparison to ipratropium RESPIMAT (20 mcg) for FEV1 AUC4-6h on Test Day 85, to demonstrate the contribution of ipratropium in the combination product.
