Why?Why?
a) More flexible production processb) No organic solvents necessaryc) Adaptable at Lichtwer’s Facilities
Three production scale batches according Three production scale batches according ICH-Guidelines have been manufactured ICH-Guidelines have been manufactured successfully in Aug 2003successfully in Aug 2003
The residual water content of the tablets are The residual water content of the tablets are 2.6 to 2.8% (limit: 3.5%)2.6 to 2.8% (limit: 3.5%)
The batches have been packed in PE bottles and The batches have been packed in PE bottles and COC300 Blister (Alu/Alu blister coming up next)COC300 Blister (Alu/Alu blister coming up next)
