- Pellets without a modulatory substance with microcrystalline cellulose serve as a comparison (Example 5). In this way, effects such as an accelerated or a slowed release of active ingredient can be determined independently of the matrix.
- a mixture of 1290 g of theophylline powder, 65 g of Kollidon 25 and 6.5 g of Aerosil 200 is sprinkled onto 700 g of core material in a coating pan and by simultaneously spraying a solution of 33 g of theophylline and 10 Kollidon 25 in 500 g of demineralized water onto the core material bound.
- a spray suspension of 400 g EUDR1AGIT RS 30 D (corresponding to 120 g polymer), 60 g talc, 24 g triethyl citrate, 0.6 g iron oxide yellow and 538, is sprayed into 600 g of the theophylline pellets thus produced with a non-retarded modulator core.
- 3 g demineralized water applied applied. The amount of polymer applied thus corresponds to 20% of the starting material.
- the release values show the characteristic curve 1 for diffusion processes. Order. Without a control of the modulator release, an equilibrium in the coated pellet quickly results, which finally adjusts the permeability of the final coating at the start of the release.
- the release profile of the pellets with microcrystalline cellulose (Ex. 5) lies between those with sodium acetate and sodium chloride. This results in an accelerating effect for sodium acetate, citric acid and sodium succinate and a reducing effect for sodium chloride.
- a mixture of 1290 g of theophylline powder, 65 g of Kollidon 25 and 6.5 g of Aerosil 200 is sprinkled onto 70 g of the cores thus produced with retarded modulator release and by simultaneous spraying of a solution of 33 g of theophylline and 10 collidon 25 in 500 g of demineralized water bound to the core material.
- a spray suspension of 400 g would become the core in a fluidized bed system
- EUDRAGIT® RS 30 D (corresponding to 120 g polymer), 60 g talc, 24 g
- Triethyl citrate 0.6 g yellow iron oxide and 538.3 g demineralized water.
- the release curve shows a course of the 0th order, ie it is almost linear.
- Example 7 “Fast / Slow"
- 500 g sodium chloride are mixed in a forced mixer with 500 g EUDRAGIT® RS PO (copolymer powder), and after the addition of 100 g triethyl citrate, melt granulated at a temperature of 70 ° C.
- EUDRAGIT® RS PO copolymer powder
- a mixture of 1100 g of theophylline powder, 190 g of sodium succinate, 65 g of Kollidon 25 and 6.5 g of Aerosil 200 are sprinkled on 700 g of the cores thus produced with a delayed modulator release and by simultaneous spraying of a solution of 33 g of theophylline and 10 Kollidon 25 bound to the core material in 500 g demineralized water.
- a mixture of 1100 g of theophylline powder, 190 g of sodium chloride, 65 g of Kollidon 25 and 6.5 g of Aerosil 200 is sprinkled on 700 g of the cores thus produced with retarded modulator release, and by simultaneous spraying of a solution of 10 Kollidon 25 in 500 g of demineralized water bound to the core material.
- a spray suspension of 400 g EUDRAGIT® RS 30 D (corresponding to 120 g polymer), 60 g talc, 24 g triethyl citrate, 0.6 g iron oxide yellow and 538, is sprayed into 600 g of the theophylline pellets with retarded modulator core produced in this way in a fluidized bed system. 3 g of demineralized water applied. The amount of polymer applied thus corresponds to 20% of the starting material.
- 500 g of sodium acetate are mixed in a forced mixer with 500 g
- a mixture of 760 g of theophylline powder, 560 g of sodium chloride, 65 g of Kollidon 25 and 6.5 g of Aerosil 200 is sprinkled on 700 g of the cores thus produced with delayed modulator delivery / active ingredient delivery and by simultaneous spraying of a solution of 10 g of Kollidon 25 g bound in 500 g demineralized water to the core material.
- a spray suspension of 400 g EUDRAGIT RS 30 D (corresponding to 120 g polymer), 60 g talc, 24 g triethyl citrate, 0.6 g iron oxide yellow and 538.3 are placed in a fluidized bed system on 600 g of the theophylline pellets with retarded modulator core thus produced g of demineralized water.
- the amount of polymer applied thus corresponds to 20% of the starting material.
- the active ingredient is released within a period of 10 hours, whereby the initial release is very low. A continuous strong acceleration of the release can be observed over the examined period.
- EUDRAGIT® RS copolymer of 65% by weight methyl methacrylate, 30% by weight ethyl acrylate and 5% by weight 2-trimethylammonium ethyl methacrylate chloride.
- EUDRAGIT® NE copolymer of 50% by weight methyl methacrylate and 50% by weight ethyl acrylate.
