HPMC – Hydroxypropylmethylcellulose

The acceptability and palatability of a dosage form are extremely important to improve patient compliance. Mixing oral solid dosage forms with food carriers is often necessary to ease swallowing and provide the taste-masking effect. The present research investigated how a liquid or semisolid carrier…

Hydrophilic matrix tablets are a type of sustained release dosage form characterized by distributing a drug in a matrix that is usually polymeric. Tolcapone is a drug that inhibits the enzyme catechol-O-methyl transferase. In recent years, it has been shown that tolcapone is a potent inhibitor of…

Flurbiprofen (FBP) is an ibuprofen derivative with less gastric side effects and short biological half-life (4.7–5.7 h). The study aimed to formulate FBP as a sustained-release pellets by extrusion/spheronization to overcome its short half-life and to decrease dose frequency. The wet mass of the…

Elucidating the impact of excipient variability on oral product performance in a biopharmaceutical perspective would be beneficial and allow excipient implementation on Quality by Design (QbD) approaches. The current study investigated the impact of varying viscosity of binders (hypromellose (HPMC))…

Liposomes, due to their mimetic cellular composition, are gaining great attention as release systems for lipophilic and hydrophilic molecules. However, liposomes can present a high tendency to degrade and aggregate into biological fluids and under storage conditions. To overcome these limitations,…

The extensive use of oral dosage forms for the treatment of diseases may be linked to deficient pharmacokinetic properties. In some cases the drug is barely soluble; in others, the rapid transit of the formulation through the gastrointestinal tract (GIT) makes it dicult to achieve therapeutic levels…
