Extemporaneous preparation of paediatric oral formulations with sildenafil citrate
The paediatric population is composed of several very diferent subgroups, each with its own specifc characteristics. For this reason, children cannot be considered “small adults”. The development of formulations suitable for children is a complex process, as it must consider the physiological…

Immediate-release dosage form; focus on disintegrants use as a promising excipient
Disintegrants are materials or mixtures of substances added in the drug formulations, which make easier dispersion or breakup of tablets and ingredients of capsules in small-scale particles for fast dissolution then it comes in contact with water in the GI tract. Immediate drug release dosage forms…

Comparison of properties on Orally Disintegrating Tablets (ODTs) produced by direct compression or…
Abstract
Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the…

Carboxymethyl starch films as enteric coatings: Processing and mechanistic insights
This study proposes the application of carboxymethyl starch derivatives as tablet coatings affording gastro-protection. Carboxymethyl starch (CMS) films were obtained by casting of aqueous filmogenic starch solutions with or without plasticizers and their structural organization was followed using…

Indices for the brittleness of pharmaceutical tablets: a reassessment
Brittleness is an important mechanical property. In the classical sense, a material is considered brittle if, during loading, it behaves elastically until failure. Nevertheless, it is also sometimes understood as the fact to be resistant to breakage. In the case of pharmaceutical tablets, three…

Drug‑Excipient Compatibility Study Through a Novel Vial‑in‑Vial Experimental Setup: A Benchmark…
Abstract
Drug-excipient compatibility study (DECS) is one of the critical steps during pre-formulation studies to select the appropriate excipient to obtain a stable formulation/dosage form. As such, there is no recommended guideline for DECS. Further, the previously reported studies and protocols…

Effects of Granulated Lactose Characteristics and Lubricant Blending Conditions on Tablet Physical…
Abstract
Lactose is an excipient used extensively for bulking, diluting, and molding active pharmaceutical ingredients in tablet manufacturing. Particularly, granulated lactose (GL) intended for direct powder compression has distinct properties due to differences in manufacturing methods. It…

A starch-based implant as a controlled drug release system: Non-invasive in vivo characterization…
Solid implants are parenteral depot systems that can provide a controlled release of drugs in the desired body area over a few days to months. Finding an alternative for the two most commonly used polymers in the production of parenteral depot systems, namely Poly-(lactic acid) (PLA) and…
