Definitions

  • the present invention relates to pharmaceutical formulations in dry powder form comprising carmoterol and ciclesonide and/or pharmaceutically acceptable derivatives thereof in order to be used in symptomatic and/or prophylactic treatment of respiratory tract diseases, particularly asthma and COPD.
  • P2-adrenergic agonists used in the treatment of respiratory tract diseases such as asthma and COPD activate p2-adrenergic receptors and affect the muscles around the airways; alleviate or remove bronchospasm.
  • Carmoterol belongs to this group.
  • Corticosteroids which is another group of active agents used in the treatment of respiratory tract diseases such as asthma and COPD, are synthetic and potent anti-inflammatory drugs similar to natural corticosteroid hormones secreted by adrenal glands. It is known that corticosteroids are quite effective drugs in asthma treatment. Ciclesonide, beclometasone, budesonide, flunisolide and fluticasone are among the molecules belonging to this group.
  • combination drugs in the treatment of respiratory tract diseases such as asthma and COPD is quite effective, particularly in reducing the number of asthma attacks. Since activity of the active agents used in combination drugs can be enabled in smaller doses compared to their use alone, severity of potential side effects and/or their possibility of occurrence can decrease.
  • the dry powder formulation comprising the active agent combination has good flow characteristics is an important criterion in terms of inhalation of said formulation effectively and therefore in terms of providing an effective treatment.
  • a dry powder formulation which does not have good flow characteristics is obtained, it is seen that the formulation has low homogeneity and consequently dosing accuracy cannot be ensured during filling the dry powder formulation prepared into reservoirs of multi dose inhalators comprising more than one dose or into blister cavities of a blister package, each of them comprising one dose, or into capsules comprising one dose.
  • the fact that the dry powder formulation does not have good flow characteristics affects emptying capacity and emptying attribute negatively during inhalation of the formulation from capsule, blister or reservoir.
  • the active agent cannot reach to the lungs in sufficient amounts.
  • the active agents are diluted by various non-functional excipients.
  • the physical characteristics of these excipients which are used in quite high amounts as compared to the active agent amount in the formulations, such as average particle size have an important role in providing good flow in the dry powder formulation. Since the active agents used are delivered to the lungs in a sufficient amount and in a controlled manner in the dry powder formulation having good flow characteristics, desired therapeutic effect is obtained.
  • the inventors have developed dry powder formulations which comprise carmoterol, ciclesonide and/or pharmaceutically acceptable derivatives thereof and have high homogeneity and good flow characteristics wherein dose uniformity is ensured and sufficient amount of active agent can be delivered to the lungs.
  • the present invention relates to pharmaceutical formulations in dry powder form comprising carmoterol, ciclesonide and/or pharmaceutically acceptable derivatives thereof.
