The present invention relates to the field of a pharmaceutical technology. More specifically, the present invention relates to a pharmaceutical composition comprising sulphonylurea-class insulin secretagogue and a surface active agent. Surface active agent obtainable by reacting castor oil or hydrogenated castor oil with ethylene oxide, preferably hydrogenated castor oil, substantially improves dissolution of the sulphonylurea-class insulin secretagogue active pharmaceutical ingredient and at the same time, when both formulated into a pharmaceutical composition, ensures satisfying or exceeding other parameters like for example stability, hardness, friability and handling of said pharmaceutical composition.
