Sinus implants

PROPEL™ mometasone furoate sinus implant

<p>The PROPEL™ sinus implant maintains patency and locally delivers steroid to the sinus mucosa in patients 18 years and older following sinus surgery.</p>

Features

PROPEL™ sinus implants keep the sinuses open while releasing mometasone furoate (MF).

PROPEL™ sinus implants feature an innovative two-in-one mechanism that opens in the sinuses while delivering MF, a potent corticosteroid, directly where it is needed.2–4

  • Self-expanding design that opens and supports the sinus cavity
  • Delivers 370 mcg of MF over 30 days
  • Non-obstructive design allows for sinus mucociliary clearance and the delivery of topical rinses
  • MF present in the sinus mucosal tissue for up to 60 days5
  • Structural backbone bio-absorbs over approximately 30–45 days after placement as the sinus cavity heals

Mometasone furoate delivers a combination of potency and safety.

Drug characteristics comparison6–9

Topical corticosteroid Lipophilicity‡,6 Potency (receptor affinity)†,7 Systemic bioavailablity‡,8
Dexamethasone Very low (less than 1.0) Very low (100) High (76%)
Triamcinolone (Kenalog) Low (1.0) Low (233) Medium (46%)
Budesonide Low (1.6) Intermediate (935) Medium (34%)
Mometasone furoate High (20.0) High (2,300) Very low (less than 1%)

† Lipophilicity numbers normalized relative to triamcinolone acetonide.

‡ As measured by relative receptor binding affinity compared to dexamethasone, which is set to a value of 100. Higher values designate greater potency.

Optimal sinonasal drug characteristics7

Highly lipophilic

Readily absorbs into tissue

Targeted and potent

High glucocorticoid receptor affinity

Low systemic bioavailability

Minimize systemic effects

PROPEL™ sinus implants are clinically proven to maintain patency and improve patient outcomes following endoscopic sinus surgery by targeting inflammation, the underlying cause of chronic rhinosinusitis.
