Getting one step closer to “No Needle Dentistry”. New nasal spray allow to do dental works for upper anterior teeth.

the U.S. Food and Drug Administration approved Kovanaze™ (St. Renatus, L.L.C.), a needleless, intranasally administered spray combination of the ester anesthetic tetracaine HCl plus the vasoconstrictor oxymetazoline HCl (6 mg/0.1 mg per 0.2 mL) for regional maxillary anesthesia.1-3 Kovanaze™ is indicated for regional pulpal anesthesia when performing a restorative procedure on teeth 4 through 13 and A through J in adults and children who weigh 40 kg (88 lbs) or more.1, 3 The drug is supplied as a prefilled, single-use sprayer that delivers 6 mg tetracaine HCl and 0.1 mg oxymetazoline HCl (equivalent to 5.27 mg tetracaine and 0.088 mg oxymetazoline) in each 0.2 mL spray.1

Kovanaze™ should be administered intranasally ipsilateral (on the same side) to the maxillary tooth on which the dental procedure will be performed. Recommended doses1 are as follows:

Adults (≥ 18 years old)

2 sprays (0.2 mL per spray), 4 to 5 minutes apart

Contraindications to Kovanaze™ include: known hypersensitivity to tetracaine, benzyl alcohol, other ester local anesthetics, p-aminobenzoic acid (PABA), oxymetazoline, or any other component of the product.1 The most common adverse reactions occurring in 10% or more of patients include rhinorrhea, nasal congestion, lacrimation increased, nasal discomfort, and oropharyngeal pain.
