Inspiratory Flow Profiles

In a clinical study,
Patients with moderate to severe CF were able to use the PODHALER device1

Patient types that were able to generate the inspiratory flow rates and volumes required to receive medication included1

  • Older patients with significant disease progression and associated decreases in FEV1
  • Younger patients (aged >6 years) with inhaled volumes <1 L
    Patients followed the Instructions for Use. Pediatric patients aged 6 to 10 years of age with FEV1 <40% predicted were not evaluated.
This study explored inspiratory variables of 96 patients with CF aged ≥6 years with varying degrees of lung disease while inhaling through mouthpieces with resistance that simulated dry-powder inhaler devices. Enrolled patients were aged 6 to 53 years, with FEV1 19% to 126% predicted.2,3 TOBI PODHALER is indicated for patients with an FEV1 25% to 80% predicted.1
§A flow rate of 40 L/min represents a flow rate more than 2 standard deviations below the mean peak inspiratory flow rates measured for pediatric patients in the study.4

INDICATION

TOBI® PODHALER® (Tobramycin Inhalation Powder) 28 mg per capsule is indicated for the management of cystic fibrosis patients with Pseudomonas aeruginosa.

Safety and efficacy have not been demonstrated in patients under the age of 6 years, patients with forced expiratory volume in 1 second (FEV1) <25% or >80% predicted, or patients colonized with Burkholderia cepacia.

IMPORTANT SAFETY INFORMATION

TOBI PODHALER is contraindicated in patients with known hypersensitivity to any aminoglycoside.

Bronchospasm can occur with inhalation of TOBI PODHALER. Bronchospasm should be treated as medically appropriate.

Caution should be exercised when prescribing TOBI PODHALER to patients with known or suspected auditory, vestibular, renal, or neuromuscular dysfunction.

Ototoxicity, as measured by complaints of hearing loss or tinnitus, was reported by patients in the TOBI PODHALER clinical studies. Tinnitus may be a sentinel symptom of ototoxicity, and therefore the onset of this symptom warrants caution. Ototoxicity, manifested as both auditory and vestibular toxicity, has been reported with parenteral aminoglycosides. Vestibular toxicity may be manifested by vertigo, ataxia, or dizziness.

Caution should be exercised when prescribing TOBI PODHALER to patients with known or suspected renal dysfunction. Nephrotoxicity was not observed during TOBI PODHALER clinical studies but has been associated with aminoglycosides as a class.

TOBI PODHALER should be used cautiously in patients with neuromuscular disorders, such as myasthenia gravis or Parkinson’s disease, since aminoglycosides may aggravate muscle weakness because of a potential curare-like effect on neuromuscular function.

Aminoglycosides can cause fetal harm when administered to a pregnant woman. Patients who use TOBI PODHALER during pregnancy, or who become pregnant while taking TOBI PODHALER, should be apprised of the potential hazard to the fetus. The amount of tobramycin excreted in human breast milk is unknown. However, systemic absorption of tobramycin following inhaled administration is expected to be minimal. A decision should be made whether to discontinue nursing or TOBI PODHALER. TOBI may cause intestinal flora alteration. Advise a woman to monitor the breastfed infant for loose or bloody stools and candidiasis.

Patients receiving concomitant TOBI and parenteral aminoglycoside therapy should be monitored as clinically appropriate for toxicities associated with aminoglycosides as a class. Serum tobramycin levels should be monitored.

Concurrent and/or sequential use of TOBI PODHALER with other drugs with neurotoxic, nephrotoxic, or ototoxic potential should be avoided. Some diuretics can enhance aminoglycoside toxicity by altering antibiotic concentrations in serum and tissue. TOBI PODHALER should not be administered concomitantly with ethacrynic acid, furosemide, urea, or mannitol.

In a clinical trial, the most commonly observed adverse events with TOBI PODHALER occurring at a frequency of at least 10%, were cough, lung disorder, productive cough, dyspnea, pyrexia, oropharyngeal pain, dysphonia, hemoptysis, and headache.
