Brief Summary

Rhinitis is inflammation of the inside of the nose. Symptoms of rhinitis include itchiness, sneezing, and a "runny" nose (rhinorrhea). There are many different causes for rhinitis, including allergies, age, different irritants in the air, overacting nervous system, and others. Many current treatments for rhinitis are not helpful or are unable to be used for long periods of time. Capsaicin ("Kap-Sey-Uh-Sin") is a natural product that is found in many spicy foods, including hot peppers. This natural product has been used as a lotion to prevent pain, and scientists have found that it may reduce the symptoms of rhinitis when used as a spray in the nose. However, capsaicin is known to cause a burning sensation. This study is needed so we can figure out what doses of capsaicin cause this burning sensation, and to what level these doses cause discomfort. Capsaicin can also cause a small degree of tearing from the eyes when used as a spray in the nose, and can also cause the nose to become "runny" (rhinorrhea). When the safest dose of capsaicin spray is found, that dose can be used to treat people with rhinitis that is not getting better from standard treatments.

Outcome Measures

Primary Outcomes (8)

  • Pain - Visual Analogue Scale (VAS) - Change from 1 hour after pre-treatment baseline

    Visual analogue scale will be used to analyze participant's perception of pain with the use of intranasal capsaicinoid spray. The visual analogue scale will be presented as a single line scale that is 100mm (0mm to 100mm) in length that the patient my place a mark on to indicate the severity of their pain. The distance (mm) of this mark from the 0 set point will determine the severity score.

    Pre-treatment and Immediate (1 hour after treatment)

  • Pain - Visual Analogue Scale (VAS) - Change from 1 week after pre-treatment baseline

    Visual analogue scale will be used to analyze participant's perception of pain with the use of intranasal capsaicinoid spray. The visual analogue scale will be presented as a single line scale that is 100mm (0mm to 100mm) in length that the patient my place a mark on to indicate the severity of their pain. The distance (mm) of this mark from the 0 set point will determine the severity score.

    Pre-treatment and Delayed (1 week after treatment)

  • Rhinorrhea - Likert - Change from 1 hour after pre-treatment baseline

    Likert scale will be used to analyze participant's perception of rhinorrhea ("runny-nose") with the use of intranasal capsaicinoid spray. Likert scale choices include: None (0), Very minimal (1), Mild (2), Moderate (3), Severe (4), and Very severe (5). Only a single option may be chosen, and this will be used to determine the severity score.

    Pre-treatment and Immediate (1 hour after treatment)

  • Rhinorrhea - Likert - Change from 1week after pre-treatment baseline

    Likert scale will be used to analyze participant's perception of rhinorrhea ("runny-nose") with the use of intranasal capsaicinoid spray. Likert scale choices include: None (0), Very minimal (1), Mild (2), Moderate (3), Severe (4), and Very severe (5). Only a single option may be chosen, and this will be used to determine the severity score.

    Pre-treatment and Delayed (1 week after treatment)

  • Lacrimation - Likert - Change from 1 hour after pre-treatment baseline

    Likert scale will be used to analyze participant's perception of lacrimation ("teary-eyes") with the use of intranasal capsaicinoid spray. Likert scale choices include: None (0), Very minimal (1), Mild (2), Moderate (3), Severe (4), and Very severe (5). Only a single option may be chosen, and this will be used to determine the severity score.

    Pre-treatment and Immediate (1 hour after treatment)

Intervention Model
SINGLE GROUP
Model Details: In brief, three consecutive patients will receive the initial intervention dose, and complete a post-intervention assessment. Subsequent cohorts receive escalating doses that are determined in advance (see below). If no patients in the initial cohort experience a dose limiting toxicity, three new patients will be recruited into the subsequent cohort and each will receive the escalated dose. This process continues on until at least one patient in a cohort experiences a dose limiting toxicity. When this occurs, three new patients will be recruited but will receive the same dose as the patient who experienced a dose limiting toxicity. If no patients in this new cohort experience a dose limiting toxicity, three additional patients will be recruited and will receive the next predetermined escalated dose. However, if two of six patients experience a dose limiting toxicity, the trial is considered complete and the dose these six patients received is considered the maximum tolerated dose.
