 Tabletting: Difficulties with the flowability and compressibility of the EU garlic powder  Coating: Everything went fine…  Sugar Coating: Everything went fine…  Release: Full compliance with specifications!  GCP: Minor deviations  Résumé …

Details on Stability Studies Organic film based  Full compliance to ICH-guidelines  Up to seven different packaging materials  Two different dosage forms Aqueous film based  Reformulation of tablet core  Formulation of coating  Establishing aqueous coating procedure

Organic Film Tablets (300 mg)

 It is possible to prolong shelf life up to 4 times when… 1.the residual humidity of the tablets is limited to 3,5 – 4 % 2.a strictly humidity controlled coating procedure is applied 3.a packaging material providing a 100% humidity barrier is used  It is possible to produce the improved tablets in an economic way (e.g. no freeze drying necessary!)  Concerning the high demands on the water barrier there is no sufficient polymer blister material available  Conclusion Organic Coated Film Tablet I

 Further optimisation is possible to solve… … the poor disintegration time of the 300 mg tablets from up to 45 min to < 30 min … poor robustness of the formulation concerning high speed tabletting … residual organic solvent problem (film coating)  Conclusion Organic Coated Film Tablet II

 Transforming  Transforming… an organic film coated tablet into… an aqueous film coated tablet!  Why? a)More flexible production process b)No organic solvents necessary c)Adaptable at Lichtwer’s Facilities

 Three production scale batches according ICH-Guidelines have been manufactured successfully in Aug 2003  The residual water content of the tablets are 2.6 to 2.8% (limit: 3.5%)  The batches have been packed in PE bottles and COC300 Blister (Alu/Alu blister coming up next)  The batches are stored under 25°C/60%, 30°C/65%, and 40°C/75% conditions  Overview Status Aqueous Coated Tablets
