HPMC – Hydroxypropylmethylcellulose
Segmented intravaginal ring for the combination delivery of hydroxychloroquine and anti-CCR5 siRNA…
Vaginal drug delivery has been shown to be a promising strategy for the prevention of sexually transmitted infections. Therapy delivered at the site of infection has many advantages including improved therapeutic efficacy, reduction in systemic toxicity, and reduced potential for development of drug…

Enabling the direct compression of metformin hydrochloride through QESD crystallization
Metformin hydrochloride is a drug used in the treatment of type 2 diabetes. It shows very poor flowability and agglomeration under storage so that a direct compression of the material into tablets has not yet been successfully realized. In a previous study the authors showed that a quasi-emulsion…

Development and evaluation of a composite dosage form containing desmopressin acetate for buccal…
Desmopressin acetate (DDAVP) is an oligopeptide indicated for the treatment of primary nocturnal enuresis, for example. The poor oral bioavailability of DDAVP accelerated a shift to alternative routes of administration like nasal and oromucosal, whereby nasal administration results in high…

Anti-counterfeiting protection, personalized medicines − development of 2D identification methods…
Counterfeiting of the products for healing is as old as trading, and it is difficult to quantify the magnitude of the problem. It is known that substandard and/or falsified (SF) medicines are a growing global threat to health, and they cause serious social and economic damage. The EU has a strong…

Enabling formulations of aprepitant: in vitro and in vivo comparison of nanocrystalline, amorphous…
A deep eutectic solvent (DES) is a eutectic system consisting of hydrogen bond donor and acceptor has been suggested as a promising formulation strategy for poorly soluble drugs. A DES consisting of choline chloride and levulinic acid in a 1:2 molar ratio was used to formulate a liquid solution of…

Rheological properties of cellulosic thickeners in hydro-alcoholic media: the science behind the…
Cellulosic-based thickeners are commonly used in the preparation of hydro-alcoholic hand sanitisers. Yet, little is known about the behaviour of these polymeric dispersions in hydro-alcoholic mixtures. Here, we studied the dispersion ability and rheology of hydroxyethyl cellulose, hydroxypropyl…
