pautients
Posology
d oₐₗ
The dose of Vantobra is the same for all within the approved age range, regardless of age or weight.
r The recommended dose is one ampoule (170 mg/1.7 ml) administered twice daily (i.e. total daily dose is 2 p ampoules) for 28 days. The dose interv should be as close as possible to 12 hours and not less than 6 hours. Vantobra is taken in alternlating cycles of 28 days. A cycle of 28 days of active therapy (on-treatment period) and 28 days of rest froma treatment (off-treatment period) should be maintained.
n Missed doses i
In case of a micssed dose with at least 6 hours remaining until the next dose, the patient should inhale the dose soon as poissible. If less than 6 hours remain to the next planned dose, the patient should wait for the next d and not inhale more to make up for the missed dose.
ᵃᵈˢᵒˢᵉ e
Duration of treatment
M
Treatment should be continued on a cyclical basis for as long as the physician considers the patient is gaining clinical benefit from the treatment taking into account that long-term safety data are not available for
Vantobra. If clinical deterioration of pulmonary status is evident, additional or alternative anti-pseudomonal therapy should be considered. See also information on clinical benefit and tolerability in sections 4.4, 4.8 and 5.1.
Special populations
Elderly patients (≥65 years)
There are insufficient data in this population to support a recommendation for or against dose adjustment.
Renal impairment
There are no data in this population to support a recommendation for or against dose adjustment with Vantobra. Please also refer to nephrotoxicity information in section 4.4 and excretion information in section 5.2.
Hepatic impairment
No studies have been performed on patients with hepatic impairment. As tobramycin is not metabolised, an effect of hepatic impairment on the exposure to tobramycin is not expected.
d Patients after organ transplantation
e Adequate data do not exist for the use of inhaled tobramycin in patients after organ transplantation. No s recommendation for or against dose adjustment can be made for patients after organ transplantation.
i r Paediatric population o
There is no relevant use of Vantobra in children below 6 years of age.
h t Method of administration u a Inhalation use.
r Vantobra is administered by inhalation using the Tolero nebuliser handset perovided in the pack. For detailed instructions on use see section 6.6. g n Vantobra must not be administered by any other route or using any other device than the one provided in the o pack. The use of an alternative untested nebuliser system may alter the pulmonary deposition of the active l substance. And this in turn may alter efficacy and safety of the product.
o Where patients are receiving several inhaled medicinal products and chest physiotherapy, it is recommended n that Vantobra is used last.
t c 4.3 Contraindications u
d Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
o r p 4.4 Special warnings and precautions for use
l Ototoxicity a
Ototoxicity, manifested as both auditory toxicity (hearing loss) and vestibular toxicity, has been reported n with parenteral aiminoglycosides. Vestibular toxicity may be manifested by vertigo, ataxia or dizziness. Tinnitus may bce a sentinel symptom of ototoxicity, and therefore the onset of this symptom warrants caution.
i d toxicity, as measured by complaints of hearing loss or by audiometric evaluations, was observed Aʷuⁱᵗdʰite poarryenteral aminoglycosides and may be considered also for the inhalation route of administration. In open label studies and post-marketing experience, some patients with a history of prolonged previous or M
concomitant use of intravenous aminoglycosides have experienced hearing loss. Physicians should consider the potential for aminoglycosides to cause vestibular and cochlear toxicity and carry out appropriate assessments of auditory function during Vantobra therapy.
In patients with a predisposing risk due to previous prolonged systemic aminoglycoside therapy it may be necessary to consider audiological assessment before initiating Vantobra therapy. If a patient reports tinnitus or hearing loss during aminoglycoside therapy, the physician should consider referring them for audiological assessment.
Nephrotoxicity
Nephrotoxicity has been associated with parenteral aminoglycoside therapy. There was no evidence of nephrotoxicity during clinical trials with inhaled tobramycin and Vantobra. Caution should be exercised when prescribing Vantobra to patients with known or suspected renal dysfunction. According to current clinical practice baseline renal function should be assessed. Urea and creatinine levels should be reassessed after every 6 complete cycles of Vantobra therapy (180 days of nebulised aminoglycoside therapy).
Monitoring of serum tobramycin concentrations
Patients with known or suspected auditory or renal dysfunction should be monitored for serum tobramycin d concentrations. If oto- or nephrotoxicity occurs in a patient receiving Vantobra, tobramycin therapy should e be discontinued until serum concentration falls below 2 µg/ml.
s i Serum concentrations greater than 12 µg/ml are associated with tobramycin toxicity and treatment should be r discontinued if concentrations exceed this level.
o h Finger The serum concentration of tobramycin should only be monitored using validated methods. prick t blood sampling is not recommended due to the risk of contamination of the sample.
u Bronchospasm a
Bronchospasm can occur with inhalation of medicinal products and has been reported with the use of r nebulised tobramycin. Bronchospasm should be treated as medically appropriate.
e
The first dose of Vantobra should be used under supervision of a physgician, after taking a bronchodilator if this is part of the current regimen for the patient. FEV₁ should be menasured before and after nebulisation.
o If there is evidence of therapy-induced bronchospasm, the physician should carefully evaluate whether the l benefits of continued use of Vantobra outweighs the risks to the patient. If an allergic response is suspected, Vantobra should be discontinued. o n Neuromuscular disorders
t Vantobra should be used with great caution in patients with neuromuscular disorders such as Parkinsonism cy or other conditions characterized by myasthenia, including myasthenia gravis, as aminoglycosides may aggravate muscle weakness due to a potentuial curare-like effect on neuromuscular function.
haemoptysids ould
Haemoptysis
o Inhalation of nebulised tobramycin solutions ma induce a cough reflex. The treatment with Vantobra in r patients with active, severe sh be initiated only if the benefits of treatment are considered to p outweigh the risks of inducing further haemorrhage.
l Development of resistaance
The development n of antibiotic-resistant P. aeruginosa and superinfection with other pathogens represent potential risks asisociated with antibiotic therapy. Development of resistance during inhaled tobramycin therapy could c limit treatment options during acute exacerbations; this should be monitored.
i d precautions
Pᴼaᵗʰtiᵉeʳnets rTehceisiving concomitant parenteral aminoglycoside therapy (or any medicine affecting renal excretion, such as diuretics) should be monitored as clinically appropriate taking into account the risk of cumulative M
toxicity. includes monitoring of serum concentrations of tobramycin.
Safety and efficacy have not been studied in patients colonised with Burkholderia cepacia.
