US 2004/0019025 A1 Jan. 29, 2004 MEDICAL COMPOSITIONS COMPRISING 0010 AS would be appreciated by the skilled person, (R,R)-FORMOTEROLAND ROFLEPONIDE rofileponide contains Several asymmetric centres. The 0001. The present invention is concerned with combina present invention includes each isomer of rofileponide, par tions of (R,R)-formoterol and rofleponide, particularly com ticularly the (22R) and (22S) isomers, either in substantially positions containing a combination of (R,R)-formoterol and pure form or admixed in any proportions. The isomers of rofileponide and the use of Such compositions in medicine, rofileponide have been described previously in WO particularly in the prophylaxis and treatment of respiratory 92/13872. diseases. 0011. By the term “physiologically functional derivative” 0002 Formoterol, i.e. 2'-hydroxy-5'-(RS)-1-hydroxy-2- is meant a chemical derivative of (R,R)-formoterol or rof (RS)-p-methoxy-O-methylphenethylaminoethylforma leponide having the same physiological function as the free nilide, particularly its fumarate Salt is a well-known adreno compound, for example, by being convertible in the body receptor agonist which is now used clinically in the thereto. According to the present invention, examples of treatment of bronchial asthma and related disorders. For physiologically functional derivatives include esters. moterol includes two asymmetric centres and in a particular 0012 Suitable salts according to the invention include form exists as the (R,R)-isomer. The (R,R) isomer of for those formed with both organic and inorganic acids. Phar moterol has been described previously, for example, in maceutically acceptable acid addition Salts include but are WO98/21175 and U.S. Pat. No. 5,795,564. not limited to those formed from hydrochloric, hydrobromic, Sulphuric, citric, tartaric, phosphoric, lactic, pyruvic, acetic, 0003 WO92/13872 describes rofileponide i.e. 16C.,17o trifluoroacetic, Succinic, oxalic, fumaric, maleic, oxaloace butylidenedioxy-6C,9C.-difluoro-11B,21-dihydroxypregn-4- tic, methaneSulphonic, ethaneSulphonic, p-toluenesul ene-3,20-dione, Salts and esters thereof and pharmaceutical phonic, benzeneSulphonic, isethionic, and naphthalenecar formulations thereof.
