Therefore, the purpose ofthe investigation was to analyze Ukrainian pharmaceutical market of products with the nimesulideactive substance by dosage forms, manufacturers; to establish the quality composition of original andgeneric drugs. The objects of the study were medicinal products containing nimesulide registered in Ukraine. The study was performed by analyzing of register data, using methods of grouping, compar-ison, graphic analysis, and generalization. In the work an analysis of medicines with nimesulide by dosage form and manufacturers was carried out. The excipients composition of reference drugs fornimesulide granules for oral suspension was also investigated. It was established that 32 medicines with nimesulide are registered in Ukraine, including 28 mono-preparations. A significant part of me-dicinal products with nimesulide are solid dosage forms, namely tablets (47 %) or granules for oral suspension (22 %) which contain 100 mg of nimesulide.

Nimesulide drug products of foreign producers are dominant (59.38 %), India has a leading position (50 %). Granules are mainlyproduced by foreign manufacturers that confirms the feasibility of developing a domestic generic product.

Differences in the qualitative composition of excipients of the original and generic products which present on the Ukrainian market were observed. The composition of products more often includes sucrose as filler, сetomacrogol 1000, liquid glucose spray-dried, maltodextrin, sodium sac-charin, anhydrous citric acid, orange flavoring, corn starch, or Aerosil 200. As follows, the feasibility of development of domestic medicinal product in the form of prolonged-release tablets and granuleswas confirmed; the original product of nimesulide granules for oral suspension was determined andthe qualitative composition of the reference drugs was established.
