Arm && Interventions

Group	Intervention	Description
diazepam nasal spray (Adults)	diazepam nasal spray	One dose of diazepam nasal spray is two intranasal sprays; one in each nostril using a nasal spray device. The dose is administered while the subject is sitting up or lying down.

Primary Outcome Measures

Name	Time	Method
Olfactory Changes as Measured by the Smell Identification Test (SIT)	Screening, weeks 12, 24, 36, 48 and 51	The SIT is a 50-item multiple-choice standardized test of olfactory function. Scoring of the test in the ability to smell ranges from normal (Normosmia: score 35 - 40 Women; 34 - 40 Men); to inability to smell (Anosmia score 6 - 18); or Malingering (not engaged in the test) ranges 0 - 5.
Change From Baseline (Screening) in Nasal Mucosa.	Screening, Weeks 12, 24, 36, 48 and 51	Change from baseline treatment visits using a focused nasal exam was based on a scale of nasal irritation "none" to Grade 4 "septal perforation."
Change in Taste as Measured by a Taste Change Questionnaire	Weeks 12, 24	Change in taste questionnaire was administered to subjects at every study visit only if the subject complained of a change in taste or as needed to report a related AE. The taste change profile included sweet, salty, sour, bitter, oily, sharp, chalky, metallic. The subject rated the change on a 10-point scale ranging from a weak change (1) to very strong (10).
