SENSITIZATION COMPOSITION AND METHOD OF USE

Abstract

The present invention relates to a topical composition and method of use, specifically an oil-in-water emulsion, comprised of sweet almond oil, lavender oil, rose oil, cinnamon bark oil, and coriander seed oil in a physiologically acceptable topical carrier. The composition is applied to a circumcised human penis to enhance sensitivity, preferably twice daily for a time period of at least about two weeks. Thereafter a maintenance dose can be applied once a day to maintain a desired level of sensitivity.

Description

EXAMPLE 1

[0016] A cream prepared in the foregoing manner and contained 6 weight percent sweet almond oil, 1 weight percent lavender oil, 0.03 weight percent rose oil, 0.75 weight percent cinnamon bark oil, 0.5 weight percent coriander seed oil, 3.5 weight percent sorbitol, 2.8 weight percent isopropyl alcohol, 20 weight percent propylene glycol, 1 weight percent butylated hydroxytoluene, 1 weight percent triethanolamine, 1 weight percent benzyl alcohol, 1 weight percent benzyl benzoate, 3.5 weight percent PEG-40 hydrogenated castor oil, 1.3 weight percent acrylate/C10-30 alkyl acrylate crosspolymer, 0.1 weight percent disodium EDTA. And the remainder water. The prepared cream was administered to eight circumcised male patients (age: 28 to 65 years). A dose of about 150 milligrams was applied to the glans penis twice a day for a two week period.

[0017] Six of the eight patients reported that they experienced a lasting increased sensitivity of the glans penis after the two-week treatment period.

[0018] A preferred method of use comprises application of the composition to the glans penis twice daily for at least about two weeks, preferably in an amount in the range of about 150 to about 300 milligrams per application. Thereafter a maintenance dose can be applied once a day to maintain a desired level of sensitivity.

EXAMPLE 2

[0019] Patients 18 years of age and older experiencing symptoms of reduced penile sensitivity criteria were selected for enrollment. After the screening preparation, which included the collection and evaluation of the patients' sexual function information, Sensum+® cream (available from Innovus Pharmaceuticals, Inc., San Diego, Calif.) was shipped by mail to each patient. Sensum+® cream comprises: sweet almond oil, lavender oil, rose damascena flower oil, cinnamon bark oil, coriander seed oil, sorbitol, isopropyl alcohol, propylene glycol, butylated hydroxytoluene, triethanolamine, benzyl alcohol, benzyl benzoate, PEG-40 hydrogenated castor oil, acrylate/C10-30 alkyl acrylate crosspolymer, calcium disodium EDTA, hydrogenated jojoba oil, and distilled water. Cinnamon bark oil (Cinnamonum verum, Stem bark outer) was present at 0.1 weight percent. Patients were instructed to apply Sensum+® cream twice daily for the first two weeks (12 hour interval) followed by once daily for the remaining eight weeks. At the end of treatment period, patients were asked to complete efficacy questions and a safety survey. Efficacy data are presented as percent of patients who achieved improvement for penile sensitivity and who answered yes to improvement of ejaculatory time. Safety of the study was based on reported adverse events.

[0020] In this study, a total of 368 patients who met the age (18-year old male) and symptoms of reduced penile sensitivity criteria were enrolled in this study. Clinical efficacy evaluation and safety analysis were performed for all patients who used the product. As shown in Table 2, survey data analyses indicate that 80% (296) of the men surveyed reported an increase in sensitivity after application of Sensum+® cream and 77.4% (285) of men reported decreased ejaculation time. There were no adverse events reported by the users or their partners.

EXAMPLE 3

[0021] Patients were selected based on a survey entry questionnaire designed by Centric Research Institute (CRI) to evaluate the extent of reduced penile sensitivity on ejaculation delay in uncircumcised men with or without comorbidity of diabetes. Patients (age 18-year and older) reporting reduced penile sensitivity and delayed ejaculation (MIELT 10 minutes) were selected for enrollment. During the screening period, subjects with reduced penile sensitivity were encouraged to induce ejaculation by masturbation at three separate events with a minimum of 24 hours between each event and following the stopwatch method to establish a baseline MIELT (Masturbation-Induced Ejaculatory Latency Time). Once the enrollment period is completed, each patient was given 2 dispensers of Sensum+® cream (150 mg/pump) to apply twice daily on the glans and shaft of the penis with a 12 hour-interval between each application for 2 weeks. Subjects were instructed to abstain from any sexual activity during the first week of treatment. Subjects were asked to gather the efficacy data for penile sensitivity, overall sex life satisfaction and sexual relationship with partner at the end of the treatment period. During the second week of treatment subjects were instructed to use a stopwatch when masturbating to record the MIELT for at least 3 separate events.

[0022] The clinical variables of this study were sensitivity of the penis glans, overall sex life satisfaction, sexual relationship satisfaction with partner and Masturbation-Induced Ejaculatory Latency Time (MIELT). Changes in the penis glans sensitivity were reflected by a rating (Scale 1-10) to the question “How would you rate your penile sensitivity?” (10 being most sensitive, 1 least sensitive) at baseline and after treatment with Sensum+® cream. Answers to “How satisfied have you been with your overall sex life satisfaction?” and “How satisfied have you been with your sexual relationship with your partner?” were rated on a 1-5 scale, where 1=Very dissatisfied and 5=Very satisfied. Changes in Masturbation-Induced Ejaculation Latency Time (MIELT) at baseline and after treatment were assessed using a stopwatch method.

[0023] A total of 14 patients with reduced penile sensitivity and masturbation-induced ejaculatory latency time 10 minutes were enrolled in this study. Based on the clinical report forms (CRFs), 8 patients reported history of diabetes. Clinical efficacy evaluation and safety analysis were performed for all patients who used the product at least once. Survey data analyses indicate that at baseline, the average mean penile sensitivity was rated at 2.57±0.34 (N=14), the MIELT was 1388±125.8 seconds (N=14) and the overall sex life satisfaction and sexual relationship with partner were 1.23±0.12 (N=13). After one week treatment with Sensum+®, the mean penile sensitivity was 5.07±0.38 (N=14) (scale 1-10), the overall sex life satisfaction was 4.23±0.23 (N=13) (Scale 1-5) and the sexual relationship with partner was rated at 3.50±0.35 (N=12) (Scale 1-5). The average mean MIELT was 946.8±114.1 seconds (N=6). Statistical analysis of the mean change (Treatment baseline) for the clinical variables was statistically significant with a p value of 0.0001 for penile sensitivity, overall sex life satisfaction and sexual relationship. With respect to the MIELT, the p value was 0.0266. Reports of adverse events indicate that 14.28% (N=2) of subjects reported penile or vaginal burning.

[0024] As shown in Table 3, the results from this clinical survey study indicate that twice daily treatment for a period of two weeks with Sensum+® cream was safe and effective. Sensum+® cream improved penile sensitivity, decreased ejaculatory latency time and increased users sex life satisfaction as well as sexual relationship with partner.
