Abstract: The present invention provides compositions comprising at least one cation selected from the group consisting of Ga+3 and La+3, that effectively inhibit the discharge of nematocysts or polar capsules. The compositions described herein are effective at inhibiting nematocyst or polar capsule discharge when applied topically prior to exposure to nematocysts. The present invention further provides methods for inhibiting the discharge of nematocysts or polar capsules, comprising applying to the skin of a subject prior to contact with the nematocyst or polar capsule a compositions comprising at least one cation selected from the group consisting of Ga+3 and La+3. Thus, the present invention provides protection for swimmers, divers and fishermen, from nematocysts or polar capsules discharged from stinging marine organisms such as Cnidaria and Myxozoa.

Abstract: Compositions for inhibiting nematocyst or polar capsule discharge are provided in the form of an effective amount of antihistamine, an effective amount of antihistamine and an effective amount of at least one cation, or an effective amount of at least one cation. The compositions can be in the form of ointments or can be added to the environment surrounding the nematocysts or polar capsules. Methods of inhibiting nematocyst or polar capsule discharge using the compositions of the invention are also provided.
