Carrier base material for prolonged release therapeutic compositions

摘要: A carrier base material adapted to be combined with a therapeutically active medicament and shaped compressed form sustained release therapeutic composition having long-lasting, slow regular incremental of the upon administration, being hydroxypropylmethylcellulose or mixture either up 30% ethylcellulose sodium carboxymethylcellulose both, wherein has been subjected hydrolysis oxidation successively concurrently until carbonyl content ranges from 0.2-3.0 grams/100 grams, carboxyl 0.60-2.60 grams moisture is in range 0.5-3.9%.
