Brief Summary:
The purpose of this study is to evaluate the effects of high-dose intranasal oxytocin for treating tinnitus. The hypothesis is that high dose intranasal oxytocin can significantly reduce tinnitus severity and disability.

Condition or disease Intervention/treatment Phase
Tinnitus Drug: Oxytocin Other: Placebo nasal spray Phase 3

Detailed Description:
This is a pilot, proof of concept, placebo-controlled, parallel study. Participants will be recruited from NYU Langone Medical Center's Ear, Nose & Throat (ENT) Department and will receive either high-dose intranasal oxytocin or a nasal spray containing Pcca Mucolox and distilled water, serving as the placebo. Long term treatment with high-dose oxytocin (45 IU four times daily) may reduce the frequency and severity of tinnitus, the burden tinnitus symptoms cause patients, and improve their quality of life.

Drug Information available for: Oxytocin

Arm Intervention/treatment
Experimental: high-dose intranasal oxytocin
Subjects will be asked to use one spray in one nostril 4 times daily (9AM, 1PM, 5PM and 9 PM). Subjects will take 4 sprays daily of oxytocin for the entire study.
Drug: Oxytocin
The investigational product, oxytocin nasal spray (45 units/0.1mL for 38mL) is composed of: oxytocin powder (0.3080g), magnesium chloride crystals (2.3100g), citric acid anhydrous gran. (0.1080g), sodium citrate powder (2.1500g), sterile water for irrigation (38.000mL), and Pcca Mucolox liquid base (3.8000mL). Subjects will be asked to self-administer the study medication with 1 puff in one nostril 4 times per day
Other Name: Pitocin

Placebo Comparator: Nasal spray
Subjects swill be asked to use one spray in one nostril 4 times daily (9AM, 1PM, 5PM and 9 PM). The spray can be taken with or without food. Subjects will take 4 sprays daily of the placebo for the entire study.
Other: Placebo nasal spray
A placebo nasal spray, consisting of magnesium, chloride crystals, citric acid anhydrous gran., sodium citrate powder, sterile water for irrigation, and Pcca Mucolox liquid base. Both active drug and the placebo will appear identical in the glass bottles. The placebo will be administered in the same manner as the active study drug, with 1 puff in one nostril four times per day.

Primary Outcome Measures :
  1. Change in Visual Analogue Scale (VAS)-Rated Tinnitus Loudness [ Time Frame: Baseline, Week 9 ]

    Participants use a VAS to rate the loudness of tinnitus on an 11-point Likert scale. Total scores range from 0 (minimum) to 10 (maximum); higher scores indicate greater tinnitus loudness.

    No response to nasal spray is defined as a decrease in VAS Score of less than 2, while a patient-reported improvement is defined as a decrease in VAS Score of more than 3.
