Definitions

• the present invention is related to the method and composition for treating a patient suffering from irritations and inflammation of a cutaneous or mucosal surface of a mammal. More particularly, there is provided a method of treatment of inflammation in the vaginal cavity while mamtaining normal vaginal floral activity and to treat cutaneous and anal/vaginal irritation and inflammation with magnesium and alkali metal salts.
• hemorrhoids The most common anorectal irritation or inflammation is caused by hemorrhoids. This condition can be caused by poor sanitary conditions, constipation, bacterial infection, etc. Common treatment is with sanitary wipes, suppositories and gels.
• vaginal cavity is subject to conditions which render it as a target for disease and infection; however, it is extremely difficult to deliver an active agent to this area for an extended period of time.
• the vaginal cavity exhibits an aqueous environment containing secreting glands whose fluids create an acidic pH in the range of 3.5 to 5.5.
• the environment of the vagina is conducive to the growth of bacteria, fungi, yeast and other microorganisms since it is warm, moist, and dark. It is also the vestibule for menstrual debris and residual seminal fluid from sexual intercourse.
• the crevices of the vaginal cavity facilitate the retention of undesirable bacteria, fungi, yeast, and other microorganisms as well as the debris from menstruation and sexual intercourse.
• the vaginal cavity is also subject to considerable physical deformation, such as during sexual intercourse or the insertion of tampons.
• vulvovaginitis Infectious diseases and other inflammatory conditions affecting the vaginal mucosa and often secondarily involving the vulva are commonly referred to as vulvovaginitis. Physicians and investigators often believe that the normal vaginal flora has a nice role in protecting the vagina and contiguous tissues from various microorganisms that are causes of vulvovaginitis.
• vulvovaginitis and symptomatic vaginal discharges are caused by bacteria, usually Gardnerella vaginalis in combination with various anaerobes.
• Protozoa Trichomonas vaginalis
• Candida is a frequent cause in pregnant women and diabetics, and occasionally oral contraceptives increase susceptibility.
• Candida also causes symptoms in women who do not have the risk factors of diabetes, pregnancy, and hormonal therapy.
• Other less common causes of vulvovaginitis are other bacteria (e.g.
• Neisseria gonorrhoeae members of the Chlamydia and Mycoplsma groups, streptococci, Escherichiacoli, and staphylococci), foreign bodies, viral infections (herpes simplex and HIV infections), pinworms (Enterobius vermicularis), rituals, radiation, and tumors of the genital tract. Frequent douching, especially with chemicals, may disturb normal vaginal milieu. Deodorant sprays, laundry soaps and fabric softeners, and bath water additives may cause vulvar irritation and inflammation. Tight, nonporous, nonabsorbent underclothing, as well as poor hygiene, may foster fungal and bacterial growth. Occasionally, sensitivity to spermicides, coital lubricants, or latex in a diaphragm or condom causes irritation and inflammation.
• the pH of a healthy vaginal is mildly acidic (pH 3.5-4.5) and this acidity is thought to be generated by the production of lactic acid by lactobacilli, which form a major component of the healthy vaginal flora. Together with other factors, this acid pH is widely recognized to prevent overgrowth of undesirable endogenous microbes (Candida, harmful anaerobes, and bacteria that may cause urinary tract infections) and encourages the continued dominance of lactobacilli which, in addition to mild acidity, provides other protective mechanisms such as production of hydrogen peroxide which aids in modulating cell growth of other microbial species.
• sperms are inactivated by the mild acidity of the healthy vagina, and acid substances have been used as home made vaginal contraceptives for centuries. More recently, it has been recognized that many sexually transmitted disease pathogens and most or all enveloped STD (sexually transmitted disease) viruses (Kempf 1001, Martin 1985) including herpes simplex virus, cytomegalovirus, and human immunodeficiency virus, are also inhibited or inactivated by mild acidic pH.
• STD sexually transmitted disease
• semen contains a potent alkaline buffering capacity that neutralizes the vaginal acidity for a period of many hours after intercourse. The alkaline buffering capacity enables sperm to swim from the vagina into the cervix and upper reproductive tract.
• the elevated pH also allows certain strains of Staphylococcus aureus to produce shock toxin I, whereas production of this toxin is completely inhibited at acidic pH 5.0 (Schlievert 1983).
• loss of protective acidity may result in staphylococcal toxic shock syndrome, Candida vaginitis, bacterial vaginosis, or urinary tract infection.
• the present invention relates to method for treating a patient suffering from cutaneous or mucosal surface irritations and inflammations with the proviso that oral mucosal surfaces are excluded. More particularly, there is provided a method comprising administering an effective amount of a composition composed of: a) about 0.5 to 20% by weight, preferably about 0.6 to 10% by weight of salts comprising

• Magnesium bromide inhibits the activation of white blood cells and particularly activate kinase activity.
• White blood cells are pro-inflammatory so that their inhibition reduces further irritation.

• Osmotic pressure is a main cause for the movement of water across cell membranes and is defined as the hydrostatic pressure needed to stop the net flow of water across a membrane, e.g., a cell membrane.
• the osmotic process occurs because there is a physical and chemical tendency for solutions on different sides of a semi-permeable membrane to try to have the same concentrations of solutes in them.
• the osmolality of the compositions of the present invention can be regulated by changing the amounts of any of all components.
• the most practical method of regulating the osmolality is to change the amount of single or multiple chemical components (normally present in a large enough amount to allow varying the osmolality over a sufficient range) whose alterations will not significantly affect either the stability, the efficacy, or the other physical-chemical properties (pH, viscosity) of the composition. Based on these criteria, it is preferred to regulate the osmolality by varying the amount of the source of anions and/or source of cations. It is present in adequate amounts to allow varying the osmotic pressure over a sufficient range for various compositions. Varying amounts of, for example, magnesium chloride over the necessary range does not significantly affect the stability, the efficacy, the pH, or the viscosity of the composition. Any of the other chemical components can be varied to adjust the osmolality.
• a theoretical calculation may be performed to predict the osmolality based on the amounts of the chemical components in the composition. This is useful for an initial estimate, however, using an osmometer to measure osmolality is the method of choice.
• Osmometers are standard, reliable, and relatively easy to operate instruments, which give actual measurements that allow determination of the osmolality of the formulation of compositions with high precision.
• a 100 ml solution which is effective as a vaginal douche or urinary bladder wash is prepared as follows:
• composition is buffered to pH 4.0.

• Example 3 The composition may be used to treat vaginal or cutaneous irritations.
• a lubricant is prepared by admixing the following ingredients.
• the composition can be used to treat hemorrhoids or cutaneous irritations.
