         3 . A method of treating diseases in which inhibition of the cellular Na + /H +  exchange is of therapeutic benefit in a patient in need thereof, the method comprising administering to the patient an effective amount of the compound according to  claim 1 .  
     
     
         4 . The method according to  claim 3 , wherein the compound according to  claim 1  is administered in the form of an aqueous injectable solution, a tablet, a suppository, an ointment, a transdermal plaster, an inhalation aerosol, or a nasal spray.  
     
     
         5 . A method of treating diseases in which inhibition of the cellular Na + /H +  exchange is of therapeutic benefit in a patient in need thereof, the method comprising administering to the patient an effective amount of a hydrate of 4-[4-(2-pyrrolylcarbonyl)-1-piperazinyl]-3-trifluoromethylbenzoylguanidine hydrochloride 1  
       
         
           
           
               
               
           
         
       
     
     
         6 . A method of treating diseases in which inhibition of the cellular Na + /H +  exchange is of therapeutic benefit in a patient in need thereof, the method comprising administering to the patient an effective amount of a monohydrate of 4-[4-(2-pyrrolylcarbonyl)-1-piperazinyl]-3-trifluoromethylbenzoylguanidine hydrochloride 1  
       
         
           
           
               
               
           
         
       
     
     
         7 . A method of treating diseases in which inhibition of the cellular Na + /H +  exchange is of therapeutic benefit in a patient in need thereof, the method comprising administering to the patient an effective amount of a hemihydrate of 4-[4-(2-pyrrolylcarbonyl)-1-piperazinyl]-3-trifluoromethylbenzoylguanidine hydrochloride 1  
       
         
           
           
               
               
           
         
       
     
     
         8 . The method according to  claim 5 , wherein the a hydrate of 4-[4-(2-pyrrolylcarbonyl)-1-piperazinyl]-3-trifluoromethylbenzoylguanidine hydrochloride 1 is administered in the form of an aqueous injectable solution, a tablet, a suppository, an ointment, a transdermal plaster, an inhalation aerosol, or a nasal spray.  
     
     
         9 . The method according to  claim 6 , wherein the monohydrate of 4-[4-(2-pyrrolylcarbonyl)-1-piperazinyl]-3-trifluoromethylbenzoylguanidine hydrochloride 1 is administered in the form of an aqueous injectable solution, a tablet, a suppository, an ointment, a transdermal plaster, an inhalation aerosol, or a nasal spray.  
     
     
         10 . The method according to  claim 7 , wherein the 4-[4-(2-pyrrolylcarbonyl)-1-piperazinyl]-3-trifluoromethylbenzoylguanidine hydrochloride 1 is administered in the form of an aqueous injectable solution, a tablet, a suppository, an ointment, a transdermal plaster, an inhalation aerosol, or a nasal spray.
