Analysis of purity profiles of generic lisinopril tablets marketed in Croatia.

In view of an increasing number of generic drugs emerging, a comparative study was performed including the approved lisinopril preparations in the form of tablets marketed in Croatia, to compare purity profiles of generic drugs versus the original medicinal product. Several batches of each individual medicinal product at different stages of their shelf life were analyzed. Impurities were determined by means of high performance liquid chromatography (HPLC). Impurity profiles were demonstrated to be specific for each individual drug. Original drug, as compared to its generic copies, had the lowest values and also the lowest variability of all the tested parameters--type, total number and content of impurities--suggesting that its manufacturing process is to certain degree better controlled compared to other manufacturers. A characteristic impurity C appearing in all the assessed preparations has the lowest levels in the original drug, whereas the amount of the highest unknown impurity does not exceed 0.10% in any of the analyzed preparations. Although the original drug stands out from all the generic preparations with its purity, it can be generally concluded that, as regarding impurities levels, all the analyzed medicinal products are within the ranges of specification limits; accordingly, it is therefore not expected that, in case of lisinopril tablets, administration of the original drug as compared to any of its generic drugs, will be safer for the patient.

Regulating medicines in Croatia: five-year experience of Agency for Medicinal Products and Medical Devices.

AIM: To present the activities of the Agency for Medicinal Products and Medical Devices in the first 5 years of its existence and to define its future challenges. METHODS: Main activities within the scope of the Agency as a regulatory authority were retrospectively analyzed for the period from 2004-2008. Data were collected from the Agency's database and analyzed by descriptive statistics. RESULTS: The number of issued medicine authorizations rose from 240 in 2004 to 580 in 2008. The greatest number of new chemical and biological entities was approved in 2005. The greatest number of regular quality controls (n=5833) and special quality controls was performed in 2008 (n=589), while the greatest number of off-shelf quality controls (n=132) was performed in 2007. The greatest number of medicine labeling irregularities was found in 2007 (n=19) and of quality irregularities in 2004 (n=9). The greatest number of adverse reactions was reported in 2008 (n=1393). The number of registered medical devices rose from 213 in 2004 to 565 in 2008. CONCLUSION: Over its 5 years of existence, the Agency has successfully coped with the constant increase in workload. In the future, as Croatia enters the European Union, the Agency will have to face the challenge of joining the integrated European regulatory framework.
