Red fruit (Pandanus conoideus Lam.) boasts high β-carotene (BC) content, often consumed orally. However, absorption issues and low bioavailability due to food matrix interaction have led to transdermal delivery exploration.

However, FNL has a very low water solubility, limiting its drug formulation, therapeutic application, and bioavailability through tissues. To overcome these limitations, this study aimed to develop FNL inclusion complexes (FNL-IC) with cyclodextrin (α-cyclodextrin, sulfobutylether-β-cyclodextrin, and hydroxypropyl-γ cyclodextrin) and incorporate it into a dissolvable microneedle (DMN) system to improve solubility and drug penetration.
View Article and Find Full Text PDFFungal keratitis (FK) is a fungal infection of the cornea, which is part of the eye and causes corneal ulcers and an increased risk of permanent blindness, which is often found in species. Amphotericin B (AMB), which is a group of polyenes as the first-line treatment of FK, is effective in annihilating . However, AMB preparations such as eye drops and ointments have major drawbacks, for instance, requiring more frequent administrations, loss of the drug by the drainage process, and rapid elimination in the precornea, which result in low bioavailability of the drug.

Pulmonary hypertension (PH) is a cardiovascular disease affecting patient's life. Sildenafil citrate (SC), the first-line treatment, is present in oral and injectable forms with some drawbacks, primarily poor patient's comfort and low oral bioavailability. To counter these limitations, stratum corneum-penetrating hydrogel-forming microneedles (HFM) was created, making it easier to distribute SC transdermally.

Therefore, it is crucial to develop a new approach to overcome these problems. In this study, we developed a dry powder supplement comprising a combination approach of solid dispersion and floating gel in situ of β-carotene to enhance the solubility and achieve sustained release behavior.
