Abstract. The objective of the present study was to optimize crospovidone as a superdisintegrant and polyvinyl pyrrolidone (PVP) K-30 as a binder in ODT salbutamol sulphate. ODT salbutamol sulphate was made by direct compression technique. Optimization was carried out by the factorial design method using Design Expert 11.0 software with optimized responses, including hardness, friability, and disintegration time. The result showed that crospovidone affected the decrease in the disintegration time of ODT. PVP K-30 affected decreasing friability and increasing hardness and disintegration time of

Background: Quercetin (3,3’,4’,5,7-pentahydroxil-flavon) is a flavone and secondary metabolite known as flavonoid. Quercetin belongs to class II BCS that has low solubility and high permeability. The poor solubility of quercetin restricts the accessibility and bioavailability. Objectives: To increase the solubility, dissolution, and antioxidant activity in a solid dispersion system. Methods: Preparation of quersetin-PVP K-30 solid dispersion was conducted using the freeze-drying method at -96 degree C for 24 hours with a ratio of 1:1, 1:0.5, and 0.5:1 and a 1:1 physical mixture of quercetin-PV

Nifedipine is a drug that acts as an antihypertensive and anti-angina. Nifedipine is known as a drug with poor water solubility. This characteristic will affect the intrinsic dissolution rate so that it can affect the absorption process and reduce the amount of drug that reaches systemic circulation. One of the strategies to increase the intrinsic dissolution rate is developing nifedipine to solid dispersions form. This study aims to observe the intrinsic dissolution rate of nifedipine after it has been made into a solid dispersion. Four samples were prepared, including three solid dispersions

Several studies have explored the incorporation of additional disintegrants such as Polyvinylpyrrolidone (PVP) K-30, Sodium starch glycolate (primogel), Croscarmellose sodium (SSC), and Sodium carboxymethylcellulose (Na-CMC) to a

New formulations showed higher dissolution rates and less MDT values than the pure celecoxib. Among all, the crystals prepared with 10 % w/v PVP K-30 exhibited maximum dissolution rate (2.95±0.23%) and very less MDT values (18.50 ± 4.01 min). Hence

Polyvinylpyrrolidone (PVP) reduction effect on free and complex Ag+ and Au3+ ions was studied from optical measurements by adding a metal precursor (K-30), commonly used as a stabilizer, to PVP. It was found that PVP has a strong reduction effect on free ionic metal, such as Ag+ ion in AgNO3, but much weaker on complex ionic metals, AuCl4− in HAuCl4 and Ag(NH3)2+ in Ag(NH3)2OH. This is explained based on the coordinative field of polar group in PVP molecules.

Abstract Flufenamic acid (FFA) is a Biopharmaceutical Classification System- II (BCS-II) class drug with poor bioavailability and a lower dissolution rate. Particle size reduction is one of the conventional approaches to increase the dissolution rate and subsequently the bioavailability. The use of the liquid antisolvent method for particle size reduction of FFA was studied in this work. Ethanol and water were used as solvent and antisolvent, respectively. Experimental parameters such as solution concentration (10–40 mg/ml), flow rate (120–480 ml/h), temperature (298–328 K) and stirring speed
