Hot-melt extrusion

Techniques to overcome poor aqueous solubility of active pharmaceutical ingredients (APIs) continue to gain interest, with a reported 30% of marketed compounds classified as BCS II and 10% classified as BCS IV. Approximately 70% of new chemical entities under development may be classified as BCS II…

Parenteral depot systems can provide a constant release of drugs over a few days to months. Poly-(lactic acid) (PLA) and Poly-(lactide-co-glycolide) (PLGA) are the most commonly used polymers in the production of these systems. Finding alternatives to these polymers is of great importance to avoid…

COVID19 has caused a significant socioeconomic burden worldwide. Opioid crisis was further intensified with the increasing number of opioid overdose/misuse related deaths in last two years. Abusers have adopted newer/efficient methods for manipulating and abusing commercial opioid formulations. Food…

The 12th APV PBP World Meeting took place from 28 – 31 March 2022 in Rotterdam. There was a poster section at the event where really interesting scientific posters were presented. Therefore we asked the presenting scientists if we could share their work in addition online with the Pharma Excipients…
