Pharmaceuticals can be used in un-approved or unlicensed indications or dosages apart from their licensed use. This is called off-label use. In principle, a drug can be considered to be off label under three conditions: (i) if the approval have not been extended, although evidence of efficacy is available; (ii) if it falls into the so-called ‘grey zone’ of evidence-based medicine, within which high-level evidence is difficult to reach even for treatments which are likely to be effective and (iii) if the drug is ineffective or at least there is no reason to believe it is effective (Koçkaya et al., 2011). Off-label use is defined by the Turkish Ministry of Health (MoH) as the use of licensed pharmaceutical products in doses outside of or exceeding the scope of the registered indication and the use of unlicensed medicinal products that are imported for the purpose of individual treatment. Hence, off-label use covers both licensed and unlicensed products (Koçkaya et al., 2012). The Turkish Medicines and Medical Devices Agency (TMMDA) gives the permission of unlicensed medicine use on patient basis. Authorized wholesalers including Turkish Pharmacists’ Association (TPA) can import the drugs based on the TMMDA`s permission. These medicines are reimbursed by the Social Security Institution (SSI), the main reimbursement agency in Turkey. Until 2014, , pharmaceuticals under this status could only be imported by the Turkish Pharmacists’ Association (TPA) when wholesalers were also authorized. This study aims to understand the trends in unlicensed medicine consumption between 2011 and 2013 when the TPA was the only authorized supplier.

In the analysis, “Detailed Price List” data published on the website of the Ministry of Health’s Turkish Medicines and Medical Devices Agency(TMMDA) and “Annex 4-A Funded Medicines List” data published by Social Security Institution (SSI) were used. The lists were merged using the Excel software and generic medicine including genericized original medicines with different pricing and payment conditions compared to original medicines with no generics and other specific medicines such as blood products, enteral nutrition products, etc. and specific conditions such as medicines with no reimbursement were excluded. The analysis was made with a total of 568 original medicines with no generic. Exfactory prices were used in the analysis. The reference prices of all original medicines (100 %) are calculated by multiplying their actual reference price values with the periodic Euro value in the price list used in Turkey. In this analysis the mandatory discount rate for original drugs of 41% discount is mostly implemented by SSI. In rare cases, higher or lower discount rate can be applied. This is compatible with the implementation of the original drug reimbursement policy rules. However, further analysis should be done to obtaining more detailed information. Results
