Overcoming Challenges in Ophthalmic Formulations through Polymer Selection
Ophthalmic drugs are delivered to the eye to treat chronic diseases such as dry eye and acute conditions such as inflammation and infections.
The market for drugs administered to the eye is growing, in large part, due to our aging population and the increased prevalence of eye-related conditions…

Transdermal delivery of acemetacin loaded microemulsions: preparation, characterization, in vitro –…
The goal of this study was to see if microemulsions might be used as a transdermal drug delivery system for acemetacin (ACM). Microemulsions containing isopropyl myristate, Tween 80, Transcutol HP, Labrafil M1944 CS, ethanol, and distilled water were used to create pseudo-ternary phase diagrams. In…

Use of polyvinyl alcohol (PVA) to overcome challenges in ophthalmic formulations
Successful ophthalmic drug formulations rely on the selection of the correct polymer to ensure the desired characteristics such as retention in the eye cavity and solubility. One example of such an excipient is polyvinyl alcohol (PVA) which offers many advantages for ophthalmic drug formulations…

Thermoresponsive in-situ gel containing hyaluronic acid and indomethacin for the treatment of…
Ocular chemical burns are prevalent injuries that must have immediate and effective treatment to avoid complications. Aiming to improve bioavailability and efficacy, a poloxamer-based thermoresponsive in-situ gelling system containing hyaluronic acid and indomethacin was developed. Formulations with…

A new perspective for psoriasis: Dithranol nanosponge loaded hydrogels
We developed dithranol nanosponge integrated Carbopol hydrogel (DTHNS-HG) as a novel perspective for psoriasis management. Dithranol was chosen as antipsoriatic moiety for this system. In this study, our objective was to fabricate and evaluate DTHNS-HG for in vivo anti-psoriatic activity using mouse…

Tadalafil Nanoemulsion Mists for Treatment of Pediatric Pulmonary Hypertension via Nebulization
Oral tadalafil (TD) proved promising in treating pediatric pulmonary arterial hypertension (PAH). However, to ensure higher efficacy and reduce the systemic side effects, targeted delivery to the lungs through nebulization was proposed as an alternative approach. This poorly soluble drug was…

α-Cyclodextrin-based poly(pseudo)rotaxane for antifungal drug delivery to the vaginal mucosa
This work aimed to evaluate poly(pseudo)rotaxanes (PPRs) potential for vaginal antifungal delivery. For this, PPRs containing terbinafine (TB) 2 % were obtained using two small surfactants, Kolliphor® RH40 and Gelucire® 48/16, and different α-cyclodextrin (α-CD) concentrations (5 and 10 %). PPRs…

Days or Centuries? – Predicting the Shelf-Life of ASDS
PURPOSE
Amorphous solid dispersions (ASDs) are a state-of-the-art enabling formulation technique for poorly water-soluble drugs. Drug recrystallization in the polymer matrix highly unwanted: marks end of shelf life of such a formulation.
Overcoming the poorly understood drug recrystallization…
