Brief Summary:

The purpose of this study is to evaluate the efficacy of treatment with Promescent Lidocaine Spray compared with placebo in patients with premature ejaculation.

Condition or disease	Intervention/treatment	Phase
Premature Ejaculation	Drug: Placebo Drug: Promescent Lidocaine Spray	Phase 3

Detailed Description:

Promescent Lidocaine Spray is a non-prescription drug that is marketed under an over-the-counter drug monograph (21 CFR Section 348.10 Subpart B (a)(2)) for male genital desensitizing drug products.
