Multiple unit pellet systems (MUPS) are seen as superior in terms of intra- and inter-individual variability of in vivo drug absorption (Lehmann K, Petereit H U, Dreher D 1993, Pharm Ind 55:940-947) in combination with oral modified release products. These pellets can be filled into hard capsules or be compressed together with suitable fillers and binders into disintegrating pellet-containing tablets.

Obtained pellets were blended with granulated Extragranular portion and Magnesium stearate for lubrication and compressed to get Metoprolol extended release multiple unit pellet system.
Metoprolol succinate, Microcrystalline cellulose (Avicel PH 101) and Hydroxy Propyl Cellulose (Klucel LF) were granulated, extruded and spheronized to form Metoprolol succinate spheres. Seal coated pellets were prepared by coating Metoprolol succinate spheres with seal coating of approx. 5% buildup using Hypromellose E5 LV and Purified water. Functional coating of approx. 50% buildup was prepared by mixing ethylcellulose 100 cps, isopropyl alcohol and Purified water and coated over seal coated Metoprolol Succinate spheres. Seal coating of approx. 5% buildup was prepared by Hypromellose E5 LV and Purified water and coated over functional coated Metoprolol succinate spheres to form final coated pellets. Obtained pellets were blended with Extragranular portion containing Microcrystalline cellulose (Ceolus Kg 1000), Copovidone (Kollidon VA 64), Colloidal silicon dioxide (Aerosil 200 P), Magnesium stearate for lubrication and compressed to get Metoprolol extended release multiple unit pellet system.
Metformin hydrochloride was spheronized to form Metformin hydrochloride pellets. Seal coated pellets were prepared by coating Metformin hydrochloride spheres with seal coating of approx. 5% buildup using Opadry clear and Purified water. Functional coating of approx. 50% buildup was prepared by mixing Ethylcellulose 100 cps, Hypromellose E5 LV, Dibutyl sebacate, Talc, Isopropyl alcohol and Purified water and coated over seal coated Metformin hydrochloride spheres. Seal coating of approx. 5% buildup was prepared by Opadry clear and purified water and coated over functional coated Metformin hydrochloride spheres to form final coated pellets. Obtained pellets were blended with Extragranular portion containing Microcrystalline cellulose (Ceolus Kg 711), Copovidone (Kollidon VA 64), Colloidal silicon dioxide (Aerosil 200 P), Sodium stearyl fumarate for lubrication and compressed to get Metformin hydrochloride extended release multiple unit pellet system.
