Questions and Answers

What is one of the reasons why coated tablets are used?

  • To reduce the size of the tablets
  • To increase the speed of drug release
  • To enhance the color of the tablets
  • To hide bad taste or smell of medicines (correct)

    • What is the purpose of the outer coating on coated tablets?

  • To increase the shelf life of the tablets
  • To reduce the risk of capping and lamination
  • To protect the medicine from moisture or air (correct)
  • To improve the absorption of the medicine

    • How does the outer coating affect the way the tablet works?

  • It alters the chemical composition of the medicine
  • It delays the onset of the medicine's effects
  • It accelerates the breakdown and absorption of the medicine
  • It doesn't change how the tablet breaks down, dissolves, or gets into the body (correct)

    • strategy to overcome capping and lamination include precompression - reduces tableting rate to minimise the impact of elastic recovery forces (which causes capping), increase/change binder, reduce/ change bind as too much binder causes...?
