1 : A tablet comprising a pharmacologically effective amount of Compound I of formula (1) 
     
       
         
         
             
             
         
       
       or a pharmaceutically acceptable salt thereof in an amount from about 30% to 80% in weight of the active moiety based on the total weight of the tablet. 
     
   
   
       2 : A tablet according to  claim 1  wherein Compound I of formula (1) or a pharmaceutically acceptable salt thereof is present in an amount from about 50% to 80% in weight of the active moiety based on the total weight of the tablet. 
   
   
       3 : A tablet according to  claim 2  wherein Compound I of formula (1) is in the monomesylate salt form. 
   
   
       4 : A tablet according to  claim 3  wherein Compound I of formula (1) monomesylate is in the beta crystal form thereof. 
   
   
       5 : A tablet according to  claim 1  wherein the tablet comprises one or more pharmaceutically acceptable excipients suitable for the preparation of tablets. 
   
   
       6 : A tablet according to  claim 5  wherein the excipient comprises at least one binder. 
   
   
       7 : A tablet according to  claim 5  wherein the excipients comprise:
 at least one binder in a total amount of about 1% to 25% in weight based on the total weight of the tablet,   at least one disintegrant in a total amount of about 10% to 35% in weight based on the total weight of the tablet   at least one glidant in a total amount of about 0.5% to 3% in weight based on the total weight of the tablet, and/or   at least one lubricant in a total amount of about 0.5% to 2% in weight based on the total weight of the tablet.   
   
   
       8 : A tablet according to  claim 6  wherein the binder comprises microcrystalline cellulose or hydroxypropylmethyl cellulose or a mixture thereof. 
   
   
       9 : A tablet according to  claim 7  wherein the disintegrant comprises cross-linked polyvinylpyrrolidinone. 
   
   
       10 : A tablet according to  claim 7  wherein the glidant comprises colloidal silicon dioxide and/or colloidal anhydrous silica. 
   
   
       11 : A tablet according to  claim 7  wherein the lubricant comprises magnesium stearate. 
   
   
       12 : A process for the preparation of a tablet according to  claim 1 , which process comprises
 (i) mixing the Compound I of formula (1) or pharmaceutically acceptable salts thereof and pharmaceutically acceptable excipients;   (ii) wet-granulating;   (iii) mixing with pharmaceutically acceptable excipients to form a mixture; and   (iv) compressing the mixture obtained in step (iii) to form a tablet.   
   
   
       13 : The process according to  claim 12  wherein the tablet is coated. 
   
   
       14 : A tablet according to  claim 1  prepared by a wet-granulation process. 
   
   
       15 : A method of treating a subject which comprises administering a tablet according to  claim 1  comprising a pharmacologically effective amount of Compound I of formula (1) to a subject in need of such a treatment.
