In the U.S.
In Canada
Available Dosage Forms:
Therapeutic Class: Antianginal
Chemical Class: Nitrate
Nitroglycerin transdermal is used to prevent angina (chest pain) caused by coronary artery disease. It does not work fast enough to relieve the pain of an angina attack that has already started.
Nitroglycerin transdermal belongs to the group of medicines called nitrates. It works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart while reducing its work load. When used regularly on a long-term basis, this helps prevent angina attacks from occurring.
This medicine is available only with your doctor's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of nitroglycerin transdermal in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of nitroglycerin transdermal in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving nitroglycerin transdermal.

Solution for injection.
Clear to opalescent, slightly yellow to brown solution.
Xolair is indicated in adults, adolescents and children (6 to <12 years of age).
Xolair treatment should only be considered for patients with convincing IgE (immunoglobulin E) mediated asthma (see section 4.2).
Adults and adolescents (12 years of age and older)
Xolair is indicated as add-on therapy to improve asthma control in patients with severe persistent allergic asthma who have a positive skin test or in vitro reactivity to a perennial aeroallergen and who have reduced lung function (FEV1 <80%) as well as frequent daytime symptoms or night-time awakenings and who have had multiple documented severe asthma exacerbations despite daily high-dose inhaled corticosteroids, plus a long-acting inhaled beta2-agonist.
Children (6 to <12 years of age)
Xolair is indicated as add-on therapy to improve asthma control in patients with severe persistent allergic asthma who have a positive skin test or in vitro reactivity to a perennial aeroallergen and frequent daytime symptoms or night-time awakenings and who have had multiple documented severe asthma exacerbations despite daily high-dose inhaled corticosteroids, plus a long-acting inhaled beta2-agonist.
Xolair treatment should be initiated by physicians experienced in the diagnosis and treatment of severe persistent asthma.
Posology
The appropriate dose and frequency of Xolair is determined by baseline IgE (IU/ml), measured before the start of treatment, and body weight (kg). Prior to administration of the initial dose, patients should have their IgE level determined by any commercial serum total IgE assay for their dose assignment. Based on these measurements, 75 to 600 mg of Xolair in 1 to 4 injections may be needed for each administration.
Patients with IgE lower than 76 IU/ml were less likely to experience benefit (see section 5.1). Prescribing physicians should ensure that adult and adolescent patients with IgE below 76 IU/ml and children (6 to < 12 years of age) with IgE below 200 IU/ml have unequivocal in vitro reactivity (RAST) to a perennial allergen before starting therapy.
See Table 1 for a conversion chart and Tables 2 and 3 for the dose determination charts in adults, adolescents and children (6 to <12 years of age).
Patients whose baseline IgE levels or body weight in kilograms are outside the limits of the dose table should not be given Xolair.
The maximum recommended dose is 600 mg omalizumab every two weeks.

Treatment duration, monitoring and dose adjustments
Xolair is intended for long-term treatment.Clinical trials have demonstrated that it takes at least 12
Discontinuation of Xolair treatment generally results in a return to elevated free IgE levels and associated symptoms. Total IgE levels are elevated during treatment and remain elevated for up to one year after the discontinuation of treatment. Therefore, re-testing of IgE levels during Xolair treatment cannot be used as a guide for dose determination. Dose determination after treatment interruptions lasting less than one year should be based on serum IgE levels obtained at the initial dose determination. Total serum IgE levels may be re-tested for dose determination if treatment with Xolair has been interrupted for one year or more.
Doses should be adjusted for significant changes in body weight (see Tables 2 and 3).
Special populations
Elderly (65 years of age and older)
There are limited data available on the use of Xolair in patients older than 65 years but there is no evidence that elderly patients require a different dose from younger adult patients.
Renal or hepatic impairment
There have been no studies on the effect of impaired renal or hepatic function on the pharmacokinetics of Xolair. Because omalizumab clearance at clinical doses is dominated by the reticular endothelial system (RES) it is unlikely to be altered by renal or hepatic impairment. While no particular dose adjustment is recommended for these patients, Xolair should be administered with caution (see section 4.4).
Paediatric population
The safety and efficacy of Xolair in children below age 6 have not been established. No data are available.
Method of administration
For subcutaneous administration only. Do not administer by the intravenous or intramuscular route.
The injections are administered subcutaneously in the deltoid region of the arm. Alternatively, the injections can be administered in the thigh if there is any reason precluding administration in the deltoid region.
There is limited experience with self-administration of Xolair. Therefore treatment is intended to be administered by a healthcare provider only (see section 6.6 and also information for the healthcare professional section of the package leaflet).
Hypersensitivity to the active substance or to any of the excipients.
General
Xolair is not indicated for the treatment of acute asthma exacerbations, acute bronchospasm or status asthmaticus.
Xolair has not been studied in patients with hyperimmunoglobulin E syndrome or allergic bronchopulmonary aspergillosis or for the prevention of anaphylactic reactions, including those provoked by food allergy, atopic dermatitis, or allergic rhinitis. Xolair is not indicated for the treatment of these conditions.
Xolair therapy has not been studied in patients with autoimmune diseases, immune complex-mediated conditions, or pre-existing renal or hepatic impairment (see section 4.2). Caution should be exercised when administering Xolair in these patient populations.
Abrupt discontinuation of systemic or inhaled corticosteroids after initiation of Xolair therapy is not recommended. Decreases in corticosteroids should be performed under the direct supervision of a physician and may need to be performed gradually.
Immune system disorders
• Allergic reactions type I
Type I local or systemic allergic reactions, including anaphylaxis and anaphylactic shock, may occur when taking omalizumab, also with onset after a long duration of treatment. Most of these reactions occurred within 2 hours after the first and subsequent injections of Xolair but some started beyond 2 hours and even beyond 24 hours after the injection. Therefore medicinal products for the treatment of anaphylactic reactions should always be available for immediate use following administration of Xolair. Patients should be informed that such reactions are possible and prompt medical attention should be sought if allergic reactions occur.
Anaphylactic reactions were rare in clinical trials (see section 4.8).
Antibodies to omalizumab have been detected in a low number of patients in clinical trials trials (see section 4.8). The clinical relevance of anti-Xolair antibodies is not well understood.
• Serum sickness
Serum sickness and serum sickness-like reactions, which are delayed allergic type III reactions, have been seen in patients treated with humanised monoclonal antibodies including omalizumab. The suggested pathophysiologic mechanism includes immune-complex formation and deposition due to development of antibodies against omalizumab. The onset has typically been 1
• Churg-Strauss syndrome and hypereosinophilic syndrome
Patients with severe asthma may rarely present systemic hypereosinophilic syndrome or allergic eosinophilic granulomatous vasculitis (Churg-Strauss syndrome), both of which are usually treated with systemic corticosteroids.
In rare cases, patients on therapy with anti-asthma medicinal products, including omalizumab, may present or develop systemic eosinophilia and vasculitis. These events are commonly associated with the reduction of oral corticosteroid therapy.
In these patients, physicians should be alert to the development of marked eosinophilia, vasculitic rash, worsening pulmonary symptoms, paranasal sinus abnormalities, cardiac complications, and/or neuropathy.
Discontinuation of omalizumab should be considered in all severe cases with the above mentioned immune system disorders.
Malignancies
During clinical trials in adults and adolescents 12 years of age and older, there was a numerical imbalance in cancers arising in the Xolair (0.5%; 25 cancers in 5,015 patients) treatment group compared with the control (0.18%; 5 cancers in 2,854 patients) group. Malignancies were uncommon (<1/100) in both the active and the control group. The diversity in the type of cancers observed, the relatively short duration of exposure and the clinical features of the individual cases render a causal relationship unlikely. The overall observed incidence rate of malignancy in the Xolair clinical trial programme was comparable to that reported in the general population.
Parasitic (helminth) infections
IgE may be involved in the immunological response to some helminth infections. In patients at chronic high risk of helminth infection, a placebo-controlled trial showed a slight increase in infection rate with omalizumab, although the course, severity, and response to treatment of infection were unaltered. The helminth infection rate in the overall clinical programme, which was not designed to detect such infections, was less than 1 in 1,000 patients. However, caution may be warranted in patients at high risk of helminth infection, in particular when travelling to areas where helminthic infections are endemic. If patients do not respond to recommended anti-helminth treatment, discontinuation of Xolair should be considered.
Cytochrome P450 enzymes, efflux pumps and protein-binding mechanisms are not involved in the clearance of omalizumab; thus, there is little potential for drug-drug interactions. Medicinal product or vaccine interaction studies have not been performed with Xolair. There is no pharmacological reason to expect that commonly prescribed medicinal products used in the treatment of asthma will interact with omalizumab.
In clinical studies Xolair was commonly used in conjunction with inhaled and oral corticosteroids, inhaled short-acting and long-acting beta agonists, leukotriene modifiers, theophyllines and oral antihistamines. There was no indication that the safety of Xolair was altered with these other commonly used anti-asthma medicinal products. Limited data are available on the use of Xolair in combination with specific immunotherapy (hypo-sensitisation therapy). In a clinical trial where Xolair was co-administered with immunotherapy, the safety and efficacy of Xolair in combination with specific immunotherapy were found to be no different to that of Xolair alone.
Xolair may indirectly reduce the efficacy of medicinal products for the treatment of helminthic or other parasitic infections (see section 4.4).
Pregnancy
There are no adequate data from the use of omalizumab in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development (see section 5.3). Omalizumab crosses the placental barrier and the potential for harm to the foetus is unknown. Omalizumab has been associated with age-dependent decreases in blood platelets in non-human primates, with a greater relative sensitivity in juvenile animals (see section 5.3). Xolair should not be used during pregnancy unless clearly necessary.
Breast-feeding
It is not known whether omalizumab is excreted in human breast milk. Omalizumab is excreted into non-human primate breast milk and risk to the suckling child cannot be excluded. Women should not breast-feed during Xolair therapy.
Fertility
There are no human fertility data for omalizumab. In specifically-designed non-clinical fertility studies, including mating studies, no impairment of male or female fertility was observed following repeated dosing with omalizumab at dose levels up to 75 mg/kg. Furthermore, no genotoxic effects were observed in separate non-clinical genotoxicity studies (see section 5.3).
Xolair has no or negligible influence on the ability to drive and use machines.
Over 4,400 allergic asthma patients were randomised in controlled efficacy trials with Xolair.
During clinical trials in adult and adolescent patients 12 years of age and older, the most commonly reported adverse reactions were injection site reactions, including injection site pain, swelling, erythema and pruritus, and headaches. In clinical trials in children 6 to <12 years of age, the most commonly reported adverse reactions suspected of being related to the medicinal product were headache, pyrexia and upper abdominal pain. Most of the reactions were mild or moderate in severity.
Table 4 lists the adverse reactions recorded in clinical studies in the total safety population treated with Xolair by MedDRA system organ class and frequency. Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness. Frequency categories are defined as: very common (

Immune system disorders
For further information, see section 4.4.
Malignancies
The overall observed incidence rate of malignancy in adults and in adolescents 12 years of age and older in the Xolair clinical trial programme was comparable to that reported in the general population (see section 4.4).
There were no cases of malignancy with omalizumab in the clinical trials in children 6 to <12 years of age; there was a single case of malignancy in the control group.
Arterial thromboembolic events (ATE)
In controlled clinical trials and an ongoing observational study, a numerical imbalance of ATEs was observed. ATE included stroke, transient ischaemic attack, myocardial infarction, unstable angina, and cardiovascular death (including death from unknown cause). The rate of ATE in patients in the controlled clinical trials was 6.29 for Xolair-treated patients (17/2703 patient years) and 3.42 for control patients (6/1755 patient years). In Cox proportional hazards model, Xolair was not associated with ATE risk (hazard ratio 1.86; 95% confidence interval 0.73
Platelets
In clinical trials few patients had platelet counts below the lower limit of the normal laboratory range. None of these changes were associated with bleeding episodes or a decrease in haemoglobin. No pattern of persistent decrease in platelet counts, as observed in non-human primates (see section 5.3), has been reported in humans (patients above 6 years of age), even though isolated cases of idiopathic thrombocytopenia have been reported in the post-marketing setting.
Parasitic infections
In patients at chronic high risk of helminth infection, a placebo-controlled trial showed a slight numerical increase in infection rate with omalizumab that was not statistically significant. The course, severity, and response to treatment of infections were unaltered (see section 4.4).
Maximum tolerated dose of Xolair has not been determined. Single intravenous doses up to 4,000 mg have been administered to patients without evidence of dose-limiting toxicities. The highest cumulative dose administered to patients was 44,000 mg over a 20
If an overdose is suspected, the patient should be monitored for any abnormal signs or symptoms. Medical treatment should be sought and instituted appropriately.
