Abstract

Glimepiride is one of the preferred drug for the treatment of type II diabetes mellitus. Diabetes can affect gastric emptying time. Incomplete absorption of drugs often result in small bioavailability. Glimepiride was chosen as model drug because it has incomplete absorbtion due to less gastric residence time. Tablet make by direct compression using polymer carbopol, HPMC K4M and other additives. This study used factorial design. Factors that are optimazed are carbopol and HPMC K4M and responses used are floating lag time, floating duration time, mucoadhesive, dan DE 720. tablet were evaluated for invitro release characteristic for 12 hours. Area optimum obtained on the composition of the combination of Carbopol 69.20 to 70.60 mg and HPMC K4M 10.66 to 24.67 mg.   Keywords: glimepiride, floating mucoadhesive tablet, release kinetics, carbopol, HPMC K4M

Abstract

Human Immunodeficiency Virus (HIV) is a global public health concern due to its progression to acquired immunodeficiency syndrome (AIDS) and the associated high morbidity and mortality rates. Efavirenz (EFV), an antiretroviral drug, is widely used to manage HIV/AIDS. However, EFV exhibits poor aqueous solubility and variable bioavailability, necessitating techniques to enhance its solubility and dissolution for improved therapeutic efficacy. This study reviewed methods to enhance EFV solubility using data from research published between 2019 and 2023. Various approaches, including Nano Micelles, Wet Milling, Co-crystals, Physical Mixtures, Nanocrystals, Dry Milling, and Liquisolid techniques, were analysed. The results demonstrated significant solubility enhancements. For instance, Fuentes (2024) achieved a 50% dissolution efficiency using Nano Micelles, while wet milling by Prado (2024) increased dissolution from 83.48% to 99.10% over 150 minutes. Co-crystals, such as those studied by Gowda (2022), improved solubility from 94.16 µg/mL (pure EFV) to 197.32 µg/mL (EFV-DL-Alanine). Sartori's (2022) Nanocrystals technique demonstrated a dissolution efficiency of 98.41%. Furthermore, physical mixtures like Nel's (2022) combination of EFV with pea protein isolate achieved a solubility increase from 1.00 mg/mL to 2.30 mg/mL. These methods highlight advancements in solubility enhancement techniques that improve EFV’s pharmacokinetic profile. These findings can guide the development of more effective pharmaceutical formulations, improving treatment outcomes for individuals living with HIV/AIDS.

Abstract

Moringa gum is a natural polymer obtained from Moringa oleifera plant and has been used as a stabilizer, binder, disintegrant, and controlled release matrix. Moringa gum has a polyuronide group, which can potentially be a mucoadhesive agent. This study used moringa gum as a mucoadhesive agent in diltiazem HCl mucoadhesive buccal film. This research aimed to determine the effect of the combination of moringa gum and HPMC on surface pH, swelling index, and in-vitro mucoadhesive residence time. Mucoadhesive buccal films were evaluated for weight and thickness uniformity, folding resistance, drug content, surface pH, swelling index, in-vitro mucoadhesive residence time, and characterization in the form of FTIR and release studies. All formulations met the tests of uniformity of weight and thickness, folding resistance, and drug content. The results showed FB as the optimum formula with a surface pH of 5.803±0.101, a swelling index of 7.031±0.134, and a residence time of 505.67±4.51 minutes. FTIR showed no interaction, and the release study showed 82.197±1.178% release at 480 minutes. In conclusion, a combination of moringa gum and HPMC mucoadhesive buccal film has been successfully prepared with moringa gum as a mucoadhesive agent that increases the residence time.
