pharmacological reports

Pharmacodynamic properties 

  • carbocisteine  (S-carboxymethyl L-cystine)  has been shown in normal bronchitic  animal models  to  fake the nature and  amount of mucus glycoprotein  which is secreted by  the respiratory tract.
  • An increase  in the acid neutral glycoprotein ratio of the mucus and a transformation of serous cells to mucus cells is known to be the initial response to irritation and will normally be followed by hypersecretion.
  • The administration of  carbocisteine to animals exposed to  irritants indicates  that the glycoprotein  that is  secreted  remains  normal;  administration after exposure indicates that return to normal is accelerated.
  •  Studies in humans have demonstrated that  carbocisteine  reduces goblet cell hyperplasia.
  • Carbocisteine can therefore be  admistreated to have a role in the management of disorders characterized by abnormal mucus. 

pharmacokinetic properties 

  • Carbocisteine Is rapidly absorbed from the GI tract.
  • Bioavailability being low ( less than 10% of the taken dose). TC max in blood and in mucous membrane  1.5 – 2 hours, therapeutic concentration is preserved in blood within 8 hours. It is longer of all detained in blood, liver and middle ear. High concentration of the drug is accumulated in bronchial secretions (17.5% of taken dose). It is metabolized in the liver (having the effect of “first passage” through the liver). It is excreted by kidneys (60-90% – unchanged, the rest – in the form of metabolites). T ½ is 2-3.5 hours. Full excretion occurs in 3 days.
