Relenza is for adults and children at least 7 years of age who have flu symptoms that appeared within the previous day or two. Please be as specific as possible (for example, 'clinically significant PMS symptoms'). Circulating resistant variants may change from season to season. More recently, we tested the ability of Relenza to inhibit the H5N1 influenza virus, or bird flu. Relenza - the first effective flu-fighter Our expertise in determining protein structure and therapeutic design led to the development of Relenza, the first drug successful in treating the flu. In this trial, the proportion of households with at least 1 new case of symptomatic laboratory-confirmed influenza was reduced from 19.0% (32 of 168 households) for the placebo group to 4.1% (7 of 169 households) for the group receiving Relenza. Reports of overdosage from administration of Relenza have been received during postmarketing experience. usually include some or all of the following: Discuss any concerns you may have regarding RELENZA with your doctor or pharmacist. There have been postmarketing reports of delirium and abnormal behavior leading to injury in patients with influenza who were receiving neuraminidase inhibitors (NAIs), including Relenza. This evaluation is based on the combination of lower estimates of treatment effect in 5- and 6-year-olds compared with the overall trial population, and evidence of inadequate inhalation through the DISKHALER in a pharmacokinetic trial [see Use in Specific Populations (8.4), Clinical Pharmacology (12.3)].

An adult The Product Information is intended to assist healthcare professionals make decisions about treatment options and provide advice on the appropriate use of a medicine to patients. Blocking viral neuraminidase would prevent this process and result in a subclinical infection which is terminated by the animals immune system before the infection has developed to give the severe symptoms of influenza. RELENZA can be used to prevent symptoms and illness due to influenza infection. sure the inhaler is available, as very rarely you may need to use it after using RELENZA. Many but The area under the serum concentration versus time curve (AUC) ranged from 111 to 1,364 nghour/mL. Eleven subjects had Cmax median values of 43 ng/mL (range: 15 to 74) and AUC median values of 167 nghour/mL (range: 58 to 279). Neither of two 6-year-olds and one of two 7-year-olds produced measurable PIFR. The drug development program involved a collaboration between Peter Colmans group at Parkville and Peter Andrews group at the Department of Medicinal Chemistry, Victorian College of Pharmacy (now part of Monash University). Level 2, 971 Burke Road, Camberwell, VIC 3124 Australia. Relenza may also be given to prevent influenza in people who may be exposed but do not yet have symptoms. patients should be observed for signs of unusual behaviour and contact your doctor in the lungs. for advice, if you think you or anyone else may have taken too much RELENZA, even unless your doctor says you should. Peter Colman discussed the possibility of using the 3D structure for the development of a neuraminidase inhibitor with Glaxo in London in 1983. QUALITATIVE AND QUANTITATIVE COMPOSITION Each RELENZA ROTADISK consists of four regularly spaced double foil blisters each containing a powder mixture of zanamivir (5 mg) and lactose monohydrate (20 mg). At this time, there was a major influenza virus program in place at the Division being run by Colin Ward. Abbotsford, Victoria, 3067. Safety and effectiveness of Relenza for treatment of influenza have not been assessed in pediatric patients younger than 7 years, but were studied in a Phase 3 treatment trial in pediatric subjects, where 471 children aged 5 to 12 years received zanamivir or placebo [see Clinical Studies (14.1)]. Instead, the development and testing of new neuraminidase inhibitors against influenza virus was undertaken in Melbourne, supported by Biota Holdings Limited, which was floated on the Australian Stock Exchange at the end of 1985. Our expertise in determining protein structure and therapeutic design led to the development of Relenza, the first drug successful in treating the flu. It works by destroying a chemical on the surface of the influenza virus. . Relenza is for administration to the respiratory tract by oral inhalation only. Therefore, If you feel you are experiencing a side-effect, talk to your doctor or pharmacist. Check with your doctor as soon as possible if you have any problems while taking RELENZA, Two seasonal prophylaxis trials assessed Relenza 10 mg inhaled once daily versus placebo inhaled once daily for 28 days during community outbreaks. I saw what I wanted and realised my goal was achievable, not the result itself, but apparently the avenue to it. Last updated on Oct 1, 2021. It has a molecular formula of C12H20N4O7 and a molecular weight of 332.3. Cell Culture: Influenza viruses with reduced susceptibility to zanamivir have been selected in cell culture by multiple passages of the virus in the presence of increasing concentrations of the drug. Do not take RELENZA after the expiry date (EXP) printed on the pack. Clinical Trials in Adults and Adolescents: Adverse events that occurred with an incidence greater than or equal to 1.5% in treatment trials are listed in Table 1. It has the following structural formula: Zanamivir is a white to off-white powder for oral inhalation with a solubility of approximately 18 mg/mL in water at 20C. In a Phase 3 trial in subjects with acute influenzalike illness superimposed on underlying asthma or chronic obstructive pulmonary disease, 10% (24 of 244) of subjects on zanamivir and 9% (22 of 237) on placebo experienced a greater than 20% decline in FEV1 following treatment for 5 days. For the prevention of influenza, it should be taken as soon as possible after an outbreak Serious bacterial infections may begin with influenza-like symptoms or may coexist with or occur as complications during the course of influenza. No consistent treatment effect was demonstrated in subjects with underlying chronic medical conditions, including respiratory or cardiovascular disease [see Warnings and Precautions (5.4)]. There have been reports of hospitalized patients with influenza who received a solution made with Relenza inhalation powder administered by nebulization or mechanical ventilation, including a fatal case where it was reported that the lactose in this formulation obstructed the proper functioning of the equipment.

Call your doctor for medical advice about side effects. ABN 40 161 366 589 The amount of drug delivered to the respiratory tract will depend on patient factors such as inspiratory flow. Limitations of available studies include the lack of specific analyses for zanamivir, possible exposure and outcome misclassification, and small sample sizes. The median time to the maximum concentration is two hours compared to one hour. Keep this medicine where children cannot reach it. The contact form is currently unavailable. position and do not hold your breath longer than is comfortable after inhaling the In a separate study, zanamivir was administered subcutaneously to pregnant rats at 3, 27, and 240 mg/kg/day in three divided doses during organogenesis (gestation Day 7 to 17). One of the defining moments of the project occurred on the evening of Friday 17 August 1982 when Peter Colman and Jose Varghese finally saw how to connect up the various fragments of electron density into a polypeptide consistent with the sequence data provided by Ward, Elleman and Azad. However, vaccination remains the . Zanamivir distributed across the placenta in pregnant rats and rabbits, with less than 0.04% of the administered maternal dose being recovered from the fetus on gestation Day 12. It may harm them. If you are about to be started on any other medication, tell your doctor or pharmacist These events are uncommon but may result in accidental injury to the patient. We have received your enquiry and will reply soon. Do not give Relenza to other people, even if they have the same symptoms that you have. Call your healthcare provider if you feel worse or develop new symptoms during or after treatment with Relenza, or if your flu symptoms do not start to get better. Following a suggestion from Peter Colman that, GlaxoSmithKline (GSK) test DANA as an anti-viral in their Ferret animal model, it was found that DANA did indeed show some inhibition of viral spread. If you have asthma or breathing problems If this occurs stop taking RELENZA and contact your doctor immediately. RELENZA should be given to children only under adult supervision and instruction, and the supervising adult should first be instructed by a healthcare professional. Available data from published studies suggest that use of Relenza during pregnancy is not associated with an increased risk of birth defects or adverse maternal or fetal outcomes. sure the inhaler is available, as very rarely you may need to use it after using RELENZA. Keep out of reach of children. These studies suggested no increased risk of major birth defects, preterm birth, or low birth weight. Because these events were reported voluntarily during clinical practice, estimates of frequency cannot be made, but they appear to be uncommon based on usage data for Relenza. For the prevention of influenza, breathe in the contents of two blisters once a day However, these studies are limited by their small sample sizes, which preclude a definitive assessment of the risk (see Data). a widespread rash with blisters and peeling skin.
