Abstract

Emulsions stabilized by solid particles are called Pickering emulsions, using diclofenac diethylamine for topical use. In this study, screening for the effect of the type of solid particles (bentonite 3%; Avicel RC-591 2.5%; and kaolin 15%) and soybean oil concentration (10%; 20%, and 30%) using the Taguchi orthogonal array method, with independent variables (type of solid particles and concentration of soybean oil, dependent variables (viscosity, pH, %EE, creaming index, globule size, and % cumulative penetration). The Pickering emulsion with Avicel RC-591 for solid particles produced a stable emulsion during 21 days of storage. Using the Taguchi orthogonal array method, the best formula based on the dependent variable is Formula 4 with physical test results at viscosity 566 cp, pH value 8.18, adsorption efficiency 55.70%, creaming index 100%, globule size 57.1 µm, cell diffusion Franz test at 120 minutes resulted in a cumulative penetration of 69.829%. The penetration power of Formula 4 is better than the emulsion with tween and span emulsifiers, which has a cumulative amount at 120 minutes of 12.609%. Therefore, Avicel RC-591 2.5% solid particles with 10% soybean oil concentration resulted in a stable Pickering emulsion and better penetration than emulsions with tween and span emulsifiers.

Abstract

Introdiction: Piroxicam is Non-Steroidal Anti-Inflammatory Drug that belongs to the BCS Class 2, characterized by low solubility. The SNEDDS (Self-Nanoemulsifying Drug Delivery System) approach for piroxicam is believed to enhance its solubility and accelerate drug release. Aims: This study aims to demonstrate that SNEDDS piroxicam has a faster drug release rate compared to piroxicam powder and commercially available piroxicam capsules. Methods: SNEDDS formulation equivalent to 20 mg of piroxicam, containing a combination of oleic acid, Kolliphor EL, and Transcutol in a ratio of 2:7:4, was tested for drug release using a dissolution method in simulated gastric fluid without enzymes at pH 1.2. The concentration of dissolved drug was measured using a validated spectrophotometric method. Result: At the 45th minute, the dissolution rate of piroxicam SNEDDS reached 101.525%, significantly higher than 47.550% achieved by piroxicam powder and 87,081 % commercially piroxicam capsules at the same time. Additionally, the dissolution efficiency of piroxicam SNEDDS is superior, with a rate of 85.539%, compared to 34.510% for piroxicam powder and 66.17% for commercially available piroxicam capsules. Conclusion: The development of a Self-Nanoemulsifying Drug Delivery System (SNEDDS) for piroxicam has shown promising potential to improve solubility and drug release, as demonstrated by superior in-vitro release rates compared to piroxicam powder and commercial piroxicam capsules

Abstract

Nifedipine as a hypertension drug has the problem of low solubility (BCS class II), leading to decreased dissolution and bioavailability. Formulation of nifedipine liquisolid using non-volatile solvents can overcome this problem. This study aimed to evaluate the effect of Transcutol P and PEG 400 as non-volatile liquisolid ingredients on the physical quality and dissolution of nifedipine liquisolid tablets. This study used seven nifedipine liquisolid formulations, each with varying concentrations of Transcutol P or PEG 400 as non-volatile solvents and lactose as carrier material. Formula 1 (20% Transcutol: 80% lactose), Formula 2 (25% Transcutol: 75% lactose), Formula 3 (30% Transcutol: 70% lactose), Formula 4 (20% PEG 400: 80% lactose), Formula 5 (25% PEG 400: 75% lactose), Formula 6 (30% PEG 400: 70% lactose), and one control formula. The nifedipine liquid produced from each formula was forged into tablets using the direct felting method with a weight of approximately 200 mg. The tablets were tested for physical quality and dissolution, and the results were statistically analyzed using SPSS version 12.0. The results showed that Transcutol P and PEG 400 as liquisolid ingredients for nifedipine tablets provided good physical quality and improved the quantity and rate of drug release. The effect of PEG 400 as a liquisolid material for nifedipine tablets slowed down the disintegration time and accelerated the dissolution rate compared with Transcutol P. The dissolution profile showed that the release of nifedipine tablets with PEG 400 liquisolid material reached 30% at the fifth minute, meeting the requirements according to Indonesian Pharmacopoeia VI, which stipulates that more than 75% should be released at the sixtieth minute
