ABSTRACT

Biosimilar products are versions of original biotechnological products produced after the patented period of the original products has been filled. Especially the production of biosimilar of biologic drugs used in the treatment of psoriasis and the concept of biosimilars have gained importance in the field of dermatology. For the production of biosimilars, the expiration of the patent period of the original drugs is required. The most important reason for the development of biosimilars is the reduction of the cost. The most important difference between biosimilar is that they are not generic drugs. The most important reason for this is the inability to make individual copies of biological drugs. There is also ambiguity about who owns the biosimilar use decision and in what circumstances the selection can be made.

ÖZET

Biyobenzer ürünler, orijinal ürünlerin patent süresi
dolduktan sonra üretilen orijinal biyoteknolojik ürünlerin versiyonlarıdır. Özelllikle
psoriasis tedavisinde kullanılan biyolojik ilaçların biyobenzerlerinin üretimi
ile biyobenzer kavramı dermatoloji alanında önem kazanmıştır. Biyobenzerlerin
üretimi için orijinal ilaçların patent sürelerinin dolması gereklidir. Biyobenzerlerin geliştirilmesinin en önemli
nedeni maliyetlerin düşürülmesidir. Biyobenzerlerin en önemli farkı jenerik
ilaç olmamalarıdır. Bunun en önemli sebebi ise biyolojik ilaçların birebir
kopyalarının yapılamamasıdır. Biyobenzer kullanım kararının kime ait olduğu,
hangi durumlarda seçimin yapılabileceği ile ilgili de kararsızlıklar vardır.
