Knowledge is a Life-long learning process

My name is Nedialko Lesev. I studied chemistry at Sofia University "St. Kl. Ohridski” and completed with a Masters’ degree "Organic materials in high technology".

My desire after completing his higher education was to engage with high level company engaged in chemical production and my main choice was Sopharma AD - a leading pharmaceutical company in Southeast Europe.

I started working at Sopharma AD in 2013 as a chemist in the labs Laboratories for Experimental Analysis of Products (ELALP) as part of the Quality Management Department. The main activities and tasks we perform are related to the development and validation of physical and chemical testing methods and quality of raw materials consumed in the production and the finished products of the company.

Another major activity that I am personally engaged in is to follow the changes that occur in various dosage forms set out in the stability program of production. I observe for changes in the physico-chemical parameters, a possible dissolution of the active substances and the amount of degradation and by-products that can be received within the before and also after the expiry date of the formulation, embedded storage under certain temperature and humidity (weather conditions).

"The wide variety of activities and number of products produced by Sopharma AD are a predisposition for new challenges". Nedialko Lesev,
Chemist in Laboratories for Experimental Analysis of Products

I am part of the team of Accredited Testing Laboratory which has an established and functioning system of quality management that is accredited by the Executive Agency "Bulgarian Accreditation Service" in accordance with the requirements of BS EN ISO / IEC 17025: 2006. During each stage of the work process we strictly adhered to European requirements of Good Laboratory Practice.

The wide variety of activities and number of products produced by Sopharma AD are a predisposition for new challenges. We solve various chemical problems daily and we have the opportunity of establishing more precise, accurate and easily reproducible analytical methods for characterizing the quality, safety and efficacy of medicinal products.

All this makes my job very interesting and gives me tremendous experience and knowledge.
