- the present invention relates to tablets of extremely long duration
- Polyvinyl alcohols are synthetic polymers used in the following
- Parteck ® SRP 80 a polyvinyl alcohol-quality, which is sold commercially, and which is a respect and compressibility
- retarding agent usually a cumulative release of about 10 to 12 hours (90 to 100% final drug release). However, some users want an even more delayed in-vitro
- a further object is to use a pulverulent, active ingredient-containing mixture with the above-mentioned, optimized PVA type (PVA 40-88) as carrier material for the production of active ingredient-containing tablets for
- PCT / EP2016 / 001430 and PCT / EP2016 / 001431 disclose that drug-containing matrix retard tablets can be prepared using these co-mixtures which, in addition to good galenic tablet properties, have drug release over 12 hours with cumulative in vitro drug release from 80 to 100% show.
- the co-mixtures which, in addition to good galenic tablet properties, have drug release over 12 hours with cumulative in vitro drug release from 80 to 100% show.
- Tablet hardness Furthermore, it is shown in these applications that for these tablets, the drug release is largely independent of the pH in the range of pH 1 to 7 and the alcohol content (0 to 40% by volume) of the release media. These are all factors that Prerequisites for preventing possible "dose-dumping" effects.
- Microcrystalline cellulose (MCC) and hydroxypropylmethylcelluloses (HPMCs) of different viscosities show good compression properties and greatly delayed in vitro drug release.
- Dissolution rate of the matrix itself is further delayed, while at the same time, however, the diffusion of the drug from the tablet is slowed down.
- microcrystalline celluloses with the addition of further hydrophilic polymers, in particular of hydroxypropylmethylcelluloses
- the formulator is enabled in a simple process (direct tabletting) to influence the in vitro release profiles of prolonged-release tablets by a simple mixing of an active ingredient (API) with a PVA / HPMC / MCC premix, and the
- Mixing ratios of the three components may be said to be "extreme" prolongation of drug release
- Especially advantageous over formulas based on HPMC alone are the significantly higher bulk and tamping densities of the PVA / HPMC / MCC combinations that allow for smaller size tablets to get at the same weight.
- Propranololtabletten show a particularly prolonged or particularly strongly retarded in vitro drug delivery.
- the drug developer obtains a quick way to make drug tablets with an extremely delayed in vitro release profile, and an active ingredient in a low-mixing mixing method with the premix consisting of the above three components, and be able to formulate the desired tablets by direct compression.
- Blending of these co-mixtures with the active ingredient here by way of example with propranolol HCl, and other additives and compression at 5, 10, 20 and 30 kN pressing force followed by galenic
- Extended-release tablets are made by direct tableting.
- very particularly preferably Co-mixtures consisting of the powdered PVA 40-88 (Parteck ® SRP 80, Merck KGaA, Germany) or 26-88 with HPMC Methocel ® K4M and K100M (both DOW), in combination with MCC Vivapur ® 102 (JRS), wherein the components PVA, HPMC and MCC preferably in the weight ratios of 50: 35 are used, and as preferred: 15: 45.5: 4.5 to 50
- Retardation matrices are used.
- compositions are kept in a closed 5 minutes
- Average data (arithmetic mean values) from 20 tablet measurements per pressing force. The measurements are made one day after the tablet is made.
- Tablet mass average (arithmetic mean) of the weighing of 20 tablets for each force: Multicheck ® 5.1 (Erweka, Germany.) With Balance Sartorius CPA 64 (from Sartorius, Germany.). The measurements are made one day after the tablet is made.
