Preparations of laxatives and antidiarrhoeals: Pharmaceutically - technological aspect

Abstract

In this report preparations of laxatives and antidiarrhoeals and the technological procedures used in production, have been reviewed.The importance of special technological procedure as freeze drying in the production and stabilisation has been explained. The most frequent dosage forms for these drugs are tablets.Good physical characteristics of tablets, insignificant variation of drug content, uniformity of dosage as required bioavailability are to bi provided by using adequate combination of excipients in the formulation and by proper selection of production method and order of technological operations.Additional requirements are to be achieved in the production of chewable tablets , frequently used as a dosage form for laxatives as calcium polycarbophil. Basic concept of tablet production validation is included in this report.

U radu su prikazani lekoviti preparati laksativa i antidijaroika i metode koje se koriste u proizvodnji. Objašnjen je značaj specijalnih tehnoloških postupaka kao što je liofilizacija u proizvodnji i stabilizaciji nekih proizvoda iz ove grupe.Najčešće primenjivani oblik ovih lekovitih supstanci su tablete. Za proizvodnju tableta koje će imati dobre fizičke karakteristike, zanemarljivo mala odstupanja u sadržaju leka, jednolikost doze kao i potrebnu bioraspoloživost, koristi se adekvatna kombinacija pomoćnih materija u formulaciji i pravilan izbor metode izrade. Dodatni zahtevi se postavljaju u slučaju proizvodnje tableta za žvakanje, kao što su tablete sa kalcijum polikarbofilom. U radu su dati i osnovni principi validacije procesa proizvodnje tableta.
