Hi,
Does anyone out there know how to conduct the dissolution
test for nicardipine HCl TABLET (not capsule, not SR) with official
method? I have been looking for UPS XXIII, EP (1997), and JP (1991,
English version), BPC (1995? 1996?) but can not find it. The information
should include as follows:
Medium: ??; volume??
Apparatus: ??
Time: ??
Procedure: ??
Tolerance: ??
Thanks in advance.

The solubilities of these dihydropyridines tend to be very low so it is
unlikely you will find a traditional dissolution method for nicardipine-
ie. you could never maintain a sink condition for USP methods I or II. You
may want to look in to a flow-through design or an extraction (two-phase)
method. Sometimes surfactants help (SLS or Tween) however, they will only
increase the solubility 2-4X at best and this is still not enough for
compounds of this nature.
