Polymer As Precipitation Inhibitor Of Weak Base Drug: An Update And Brief Review, Viviane Annisa, Syaiful Choiri, Teuku Nanda Saifullah Sulaiman, Agung Endro Nugroho Jan 2021

Polymer As Precipitation Inhibitor Of Weak Base Drug: An Update And Brief Review, Viviane Annisa, Syaiful Choiri, Teuku Nanda Saifullah Sulaiman, Agung Endro Nugroho

The Thai Journal of Pharmaceutical Sciences

Precipitation due to supersaturation phenomenon and intraluminal solubilization behavior is mainly faced on reducing bioavailability, particularly for weak base drugs. Incomplete and extend of absorption can be avoided by modification of drug-excipient interaction namely polymers. This interaction is proposed to stabilize the amorphous form of drug through reducing nucleation followed by crystal growth. Therefore, polymers can be utilized to inhibit the precipitation phenomenon through their interaction with poorly water-soluble and weak base drugs. However, until to date, there was no recent updates on the use of polymer for precipitation inhibitor of weak base drug. This review discussed the brief and …

The Thai Journal of Pharmaceutical Sciences

Snakebite, a medical emergency, is a socially significant but neglected issue in India. Antivenom serum therapy that is currently used against venomous snakebites is expensive and showed severe side effects. Traditional claims reported the use of Moringa oleifera to treat snakebite in rural India. To scientifically validate these claims, in the present investigation, the antivenom potential of the extracts of M. oleifera was investigated. The extracts effectively neutralized Russell’s viper venom-induced lethality (LD50: 10.9 μg) at 10 μg/mice and 300 μg/mice (ED50), respectively. Both extracts neutralized venom-induced hemolysis (50–100 μg). Inhibitory concentrations against phospholipase A2 activity exhibited by aqueous and …

The Thai Journal of Pharmaceutical Sciences

Objective: This study aims at investigating the effect of the hydrophilic-lipophilic balance (HLB) of non-ionic surfactants on physical property and stability of nanoemulsions. Materials and Methods: The nanoemulsions were prepared using the Microfluidizer. The oil phase consisted of 10% w/w soybean oil and 5% w/w surfactant(s). Types of nanoemulsions were confirmed by dilution test. The average droplet size and size distribution (polydispersity index [PDI]) were measured by dynamic light scattering Zetasizer Nano ZS™. The screening physical stability was done by centrifugation. Only the formulations with no phase separation were further evaluated for physical stability. Results: All nanoemulsions were single phase …

A self-microemulsifying delivery system (SMEDS) containing astaxanthin (AST) was developed and optimized using a mixture design and its desirability function. Independent factors studied in the experimental design were the amounts of castor oil, Cremophor® RH 40, and Tween® 80 in a formula. The measured response variables included droplet size, polydispersity index (PDI), zeta potential, active ingredient content, and transmittance of microemulsions obtained from the AST SMEDS formulations. The desirability function was then adjusted to optimize the formulation. The optimized AST SMEDS was composted of 19.59% castor oil, 62.34% Cremophor® RH 40, and 18.03% Tween® 80, and the resulting self microemulsions …

Hyptolide and epoxy hyptolide were successfully isolated and synthesized from Hyptis pectinata extract that potential to cure malaria diseases. The previous studies showed that these compounds contained lactone groups associated with antibacterial and anticancer activities. However, the antimalarial activity remained unclear. This study aimed to investigate the antiplasmodial activity of H. pectinata extract, hyptolide, and epoxy hyptolide. These compounds were tested in vitro for antiplasmodial activity against chloroquinesensitive 3D7 strain of Plasmodium falciparum. Thin blood smears were used to assess the levels of parasitemia and growth inhibition of the isolates and the ClpP inhibition was analyzed under well diffusion assay. …
