Preparations containing silicon dioxide to improve the taste thereof

摘要

A pharmaceutical preparation comprising a bitter tasting mixture of a decongestant such as pseudoephedrine and an antihistamine such as diphenhydramine and/or chlorpheniramine maleate is made with no bitter, metallic taste or unpleasant mouthfeel by adsorbing the active drug mixture using a wet granulation process onto a silicon dioxide carrier which comprises from about 50 to about 85 % of total weight of the adsorbate composition. A truly multi-symptom relief formula is prepared through the optional addition of an antitussive such as dextromethorphan hydrobromide and/or an analgesic such as meclofenamic acid, aspirin or ibuprofen. Additional excipients such as flavors, sweeteners, lubricants and bulk fillers are added for better taste, improved mouthfeel and as an aid to the tabletting process. Preferred preparations ar chewable tablets.
