Abstract
A process for producing wet ribavirin pellets is provided in order to make pharmaceutical dosages of ribavirin. The process is particularly useful as an alternative method for preparing pharmaceutical dosages of ribavirin that reduces the amount of ribavirin dust that is produced during the manufacturing process and allows for greater control of dissolution rates. According to the preferred embodiments, this method is accomplished through mixing ribavirin with at least one excipient into a uniform mixture, forming the mixture into a granulated mass by adding a wetting agent, shaping said granulated mass into soluble particles and drying the flowable particles. The process enables Ribavirin pharmaceutical pellets to be mixed with a binder and disintegrant to form a uniform mixture.
