<p>An oral solid dosage form having improved dissolution profile and a method of producing the same are provided. The present invention particularly provides a co-processed excipient composition and a method of producing the same. More particularly, it relates to a co-processed binary mixture of crosslinked polyvinylpyrrolidone and calcium silicate; wherein the weight ratio of crosslinked polyvinylpyrrolidone and calcium silicate is in the range of 1 : 1 to 20: 1. The binary mixture when combined with a poorly soluble drug enhances its dissolution and extent of release.</p>
