Theophylline anhydrous was purchased from Acros organics (New Jersey, USA). Directly compressible lactose monohydrate -Ludipress was supplied by BASF SE (Germany). Polyvinylpyrrolidone (PVP) K90, magnesium stearate and sodium alginate (Alg) (grade 15-20 cps) and pectin (Pec) from citrus fruits were supplied by Sigma-Aldrich Co., Ltd. (Dorset, UK). Microcrystalline cellulose (MCC) PH 101 and crosscarmellose sodium SD-711 were provided by FMC Biopolymer (Belgium). GMS (Imwittor K900) was a generous donation of IOI Oleo GmbH (Germany). The gastric medium consisted of a 0.1M hydrochloric acid solution (pH 1.2). The intestinal medium was made by adding 250 mL of 0.214 M tribasic phosphate to the gastric medium to raise the pH to 6.8.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
