4 . The composition of claim 3 , wherein the one or more nonionic surfactants are selected from the group consisting of poloxamer 407, poloxamer 188 and polyoxyl 35 castor oil.
5 . The composition of claim 1 , wherein the one or more viscosity enhancers are selected from the group consisting of cellulose derivatives, gums, dextrans, polyvinyl alcohol, polyacrylic acids, povidone, polyethylene glycol, propylene glycol, chitosans, and hyaluronates and hyaluronic acids.
6 . The composition of claim 5 , wherein the one or more viscosity enhancers are selected from the group consisting of cellulose derivatives and polyacrylic acids.
7 . The composition of claim 6 , wherein the one or more viscosity enhancers are selected from the group consisting of sodium carboxymethyl cellulose and carbomer 974P.
8 . The composition of claim 1 , further comprising one or more excipients selected from the group consisting of co-solvents and cooling agents.
9 . The composition of claim 8 , wherein the one or more excipients are selected from the group consisting of polyethylene glycol 400, menthol and isopropyl alcohol.
10 . A method of reducing or eliminating one or more conditions selected from the group consisting of pain, hemorrhoids, acne, wrinkles and scars comprising topically applying an effective amount of a composition of claim 1 to a subject in need thereof.
11 . A method of treating gastrointestinal conditions or diseases comprising applying a composition of claim 1 to a subject in need thereof.
12 . A topical analgesic composition comprising lidocaine or a salt thereof and a mixture of propylene glycol monolaurate and propylene glycol at a ratio of about 1:9, and ethanol.
13 . The composition of claim 12 , further comprising one or more surfactants and one or more viscosity enhancers.
14 . The composition of claim 13 , wherein the one or more nonionic surfactants are selected from the group consisting of poloxamer 407, poloxamer 188 and polyoxyl 35 castor oil.
15 . The composition of claim 13 , wherein lidocaine or a salt thereof is at a concentration from about 2% to about 4% w/w, the one or more nonionic surfactants are at a total concentration from about 1% to about 2% w/w, the one or more viscosity enhancers are at a concentration from about 0.5% to about 2% w/w and the mixture of propylene glycol monolaurate and propylene glycol at ratio of about 1:9 is at a concentration from about 2% to about 5% w/w.
16 . A method of reducing or eliminating pain, hemorrhoids or a combination thereof comprising topically applying an effective amount of a composition of claim 12 to a subject in need thereof.
17 . A method of treating gastrointestinal conditions or diseases comprising applying a composition of claim 12 to a subject in need thereof.
