Abstract

The present invention is a system for averting undesirable pharmacokinetic drug interaction between a drug and concomitant drug(s), which consists of controlling the in vivo release time and/or release site of the drug and/or the concomitant drug.

Claims

exact text as granted — not AI-modified
1 . A system for averting undesirable pharmacokinetic drug interaction between a drug and concomitant drug(s), which comprises controlling the in vivo release time and/or release site of the drug and/or the concomitant drug(s).  
     
     
         2 . A system for averting undesirable drug interaction between a drug and concomitant drug(s), both of which use the same route in terms of in vivo drug absorption, distribution, metabolism or excretion in humans, which comprises controlling the in vivo release time and/or release site of the drug and/or the concomitant drug(s).  
     
     
         3 - 4 . (canceled)  
     
     
         5 . A drug preparation for averting undesirable pharmacokinetic drug interaction between a drug and concomitant drug(s), which comprises controlling the in vivo release time and/or release site of the said drug.  
     
     
         6 . A drug preparation for averting undesirable drug interaction between a drug and concomitant drug(s), both of which use the same route in terms of in vivo drug absorption, distribution, metabolism or excretion in humans, which comprises controlling the in vivo release time and/or release site of the said drug.  
     
     
         7 - 9 . (canceled)  
     
     
         10 . A method for averting undesirable pharmacokinetic drug interaction between a drug and concomitant drug(s), comprising administering to patients a drug preparation with which the in vivo release time and/or release site of the said drug is controlled.  
     
     
         11 . A method for averting undesirable drug-interaction between a drug and concomitant drug, both of which use the same route in terms of in vivo drug absorption, distribution, metabolism or excretion in humans, comprising administering to patients a drug preparation with which the in vivo release time and/or release site of the said drug is controllable.  
     
     
         12 - 14 . (canceled)  
     
     
         15 . A system for averting undesirable pharmacokinetic interaction between a drug and food(s), which comprises controlling the in vivo release time and/or release site of the drug.
