Application Number:	07/117,751
Patent Claims:	1. Method of using on a subject a pharmaceutical product based on otilonium bromide as active principle, which comprises the step of applying topically by an endoscopic instrument, at a selected location inside the gastrointestinal tract of the subject, a composition formed comprising said active principle, one or more antifoaming excipients and one or more emulsifying excipients. 2. Method of claim 1 wherein said step of applying topically at a selected location inside the gastrointestinal tract of the subject includes locally applying by instillation or nebulization in the digestive or alimentary canal. 3. Method of claim 1 wherein the composition is provided in liquid form and said step of applying topically at a selected location inside the gastrointestinal tract of the subject includes topically applying to assist endoscopic procedures for at least one of diagnostic and therapeutic purposes. 4. Method of claim 1 wherein the composition is an aqueous solution containing the active principle, and the anti-foaming and emulsifying excipients. 5. Method of claim 1 wherein the composition is formed corresponding to the following formulation 6. Method of claim 1 wherein the composition is formed corresponding to the following formulation 7. Method of claim 1 wherein the composition is formed substantially at the moment of use by combining sterile water with a previously prepared dry mixture of the active principle and the antifoaming and emulsifying excipients. 8. Method of claim 7 wherein the dry mixture is stored in a storage container in conserved dry state therein and the sterile water is stored in a solvent vial, and the water is transferred from the vial to the container to form a solution substantially at the moment of use. 9. Method of claim 7 wherein the dry mixture is a powder prepared by absorbing on the active principle a solution of the excipients in an inert solvent and then drying the mixture until the solvent has been essentially completely eliminated therefrom. 10. Method of claim 7 wherein the dry mixture is a powder prepared by absorbing on the active principle a melted mixture of the excipients. 11. An endoscopic method for effecting a medical procedure in the digestive or alimentary canal including one of the esophagus, stomach, duodenum, colon, sigma and rectum of a subject for at least one of diagnostic and therapeutic purposes including bioptic sampling and removal of polypoid formations, comprising the steps of prior to effecting the medical procedure preparing a pharmaceutical product containing otilonium bromide and at least one anti-foaming excipient and at least one emulsifying excipient and applying said prepared pharmaceutical product topically by an endoscopic at a selected location inside the gastrointestinal tract of the subject. 12. An endoscopic method according to claim 1, wherein said pharmaceutical product is an aqueous solution. 13. An endoscopic method according to claim 11, wherein said step of preparing a pharmaceutical product includes preparing a composition corresponding to the following formulation: 14. An endoscopic method according to claim 11, wherein said step of preparing a pharmaceutical product includes preparing a composition corresponding to the following formulation: 15. An endoscopic method according to claim 11, wherein said step of preparing a pharmaceutical product includes forming the pharmaceutical product substantially at the moment of use by combining sterile water with a previously-prepared dry mixture of otilonium bromide and at least one anti-foaming excipient and at least on emulsifying excipient. 16. An endoscopic method according to claim 15, wherein the dry mixture is stored in a storage container in conserved dry state therein and the sterile water is stored in a solvent vial and said sterile water is transferred from the vial to the container to form the pharmaceutical product substantially at the moment of use. 17. A method according to claim 15, wherein the dry mixture is a powder prepared by absorbing on the otilonium bromide a solution of at least one anti-foaming excipient and at least one emulsifying excipient in an inert solvent and then drying the mixture until the solvent has been essentially completely eliminated therefrom. 18. An endoscopic method according to claim 15, wherein the dry mixture is a powder prepared by absorbing on the otilonium bromide a melted mixture of at least one anti-foaming excipient and at least one emulsifying excipient. 19. An endoscopic method according to claim 11, wherein the prepared pharmaceutical product is applied by an endoscopic instrument which is also, subsequently used for one of diagnostic or therapeutic purposes.
