Cardiovascular Changes and Tetracaine Pharmacokinetics Following Intranasal Administration of Standard and High Doses of Kovacaine Mist (Tetracaine Hydrochloride With Oxymetazoline Hydrochloride) in Healthy Volunteers

The purpose of this study is to determine the pharmacokinetics/pharmacodynamics and safety of a nasal spray containing the anesthetic drug tetracaine in combination with oxymetazoline

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study was to determine the safety and pharmacokinetics of the standard dose of intranasal Kovacaine Mist of 0.6 mL (18 mg tetracaine HCl with 0.3 mg oxymetazoline HCl) and a proposed maximum recommended dental dose of 1.2 mL (36 mg tetracaine HCl with 0.6 mg oxymetazoline HCl). The primary objectives were to determine if either dose significantly changed blood pressure readings (systolic and diastolic), pulse rate, or oxygen saturation levels from baseline pretreatment values and to determine the safety profile of both doses. The secondary objectives were to establish the pharmacokinetics of oxymetazoline, tetracaine, and its major metabolite (parabutylaminobenzoic acid) following the intranasal administration of both doses. Each subject received the standard dose (3 sprays in each nostril with 4 minutes between each pair of sprays) followed 1 to 3 weeks later by the high dose (as 6 sprays in each nostril).
