In known processes, effervescent tablets are manufactured from synthetic salicylic acid analgesics and possibly vitamin additives. To overcome the drawbacks of these effervescent tablets, namely irritation of the gastric mucosa and inhibition of thrombocyte agglomeration, and at the same to extend the range of applications for effervescent tablets, an effervescent tablet contains as the salicylic acid-forming agent a water-soluble plant extract of the willow bark (cortex salicis) type with a high active substance content. These extracts, which are usually extremely hygroscopic, are obtained in a galenical form. The effervescent tablet can contain large quantities of rapidly resorbed active ingredients, the salicylic acid being formed as a terminal active ingredient only in the liver. |
