The present disclosure generally relates compositions as topical creams, methods of making these topical creams, and a method of treating vaginal discomfort or bladder control issues.
Before menopause a woman's ovaries produce several different hormones including, but not limited to, estrogen. Estrogen is generally beneficial in maintaining the health and integrity of the vaginal lining. During peri-post menopause, women can experience a decline in hormone levels. The gradual decrease in hormone production causes vaginal lining shrinkage and drying due to the decrease in healthy secretions. The lining of the vagina can become less elastic and can thin, causing irritation and discomfort, also known as vaginal atrophy. Specifically, some seventy-five percent of women can experience discomfort including, but not limited to, thinning, irritation, painful intercourse, excessive dryness, increased bladder infections, loss of lactobacilli, increased vaginal pH, decreased vaginal flora, decreased desire and/or arousal, and pelvic prolapse symptoms.
Changes, as described above, can cause significant discomfort and pain. Therefore, there is a need for compositions and methods for reducing the discomfort and pain. Traditionally, such symptoms can be treated through the use of lubricating creams, as well as over-the-counter (OTC) treatments, herbal therapies, prescribed medication (such as vaginal tablets, creams, or rings), and Kegel/pelvic-strengthening exercise or surgery.
What is needed is a topical cream which relieves the symptoms of vaginal atrophy, is effective, easy to prepare, and has a long shelf life.

When introducing elements of the embodiments described herein, the articles “a”, “an”, “the” and “said” are intended to mean that there are one or more of the elements. The terms “comprising”, “including” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.
Concentrations, amounts, and other numerical data may be expressed or presented herein in a range format. It is to be understood that such a range format is used merely for convenience and brevity and should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. As an illustration, a numerical range of “about 2 to about 50” should be interpreted to include not only the explicitly recited values of 2 to 50, but also include all individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values such as 2, 2.4, 3, 3.7, 4, 5.5, 10, 10.1, 14, 15, 15.98, 20, 20.13, 23, 25.06, 30, 35.1, 38.0, 40, 44, 44.6, 45, 48, and sub-ranges such as from 1-3, from 2-4, from 5-10, from 5-20, from 5-25, from 5-30, from 5-35, from 5-40, from 5-50, from 2-10, from 2-20, from 2-30, from 2-40, from 2-50, etc. This same principle applies to ranges reciting only one numerical value as a minimum or a maximum. Furthermore, such an interpretation should apply regardless of the breadth of the ranges, or the characteristics being described.
As used herein, the term “about” is used to provide flexibility to a numerical range endpoint by providing that a given value may be “a little above” or “a little below” the endpoint. For example, the endpoint may be within 10%, 8%, 5%, 3%, 2%, or 1% of the listed value. Further, for the sake of convenience and brevity, a numerical range of “about 50 mg/mL to about 80 mg/mL” should also be understood to provide support for the range of “50 mg/mL to 80 mg/mL.” The endpoint may also be based on the variability allowed by an appropriate regulatory body, such as the FDA, USP, etc.
The present disclosure provides inclusion of additional items, materials, components, steps, or elements, that do not materially affect the basic and novel characteristics or function of the item(s) used in connection therewith. For example, trace elements present in a composition, but not affecting the composition's nature or characteristics would be permissible if present under the “consisting essentially of” language, even though not expressly recited in a list of items following such terminology. In this specification when using an open-ended term, like “comprising” or “including,” it is understood that direct support should be afforded also to “consisting essentially of” language as well as “consisting of” language as if stated explicitly and vice versa.
The term “vaginal atrophy” refers to the thinning, drying, and inflammation of the vaginal walls due to a lack of estrogen in the body.
As various changes could be made in the above-described methods without departing from the scope of the invention, it is intended that all matter contained in the above description and in the examples given below, shall be interpreted as illustrative and not in a limiting sense.
The following examples are provided to illustrate the subject matter of the present disclosure. The examples are not intended to limit the scope of the present disclosure and should not be so interpreted.
The following compositions were prepared for use in treating vaginal discomfort or bladder control issues.
