formulation development. Nepafenac is a common NSAID commercially available as a suspension, Nevanac®, due to the poor water solubility. Hydroxypropyl-beta-cyclodextrin (HPBCD) was complexed with nepafenac to increase the water solubility and transcorneal permeation of the drug. The complex in the liquid and solid state was confirmed.
In this study, we explored different formulation strategies to compound a poorly water-soluble drug into a clear oral liquid formulation, using lorazepam as a model drug. With the intended application in paediatric patients, specific attention was paid to child-friendly excipients and adequate palatability.
Ocular drug delivery is a challenging field due to the large number of ocular barriers. Therefore, producing a new ophthalmic formulation requires consideration when it comes to the administration route, dosage form and site of action. Chapter 2 will cover the basics of ophthalmic formulation development.
Sustained release drug formulations contain the pharmaceutical itself and a three component release rate controlling matrix composition. The three components of the matrix composition are (1) water insoluble polymer, such as ethyl cellulose, (2) pH dependent gelling polymer, such as sodium alginate, and (3) a pH independent gelling polymer, such as hydroxypropyl methylcellulose.

Delivering drugs in a water-insoluble formulation is a critical matter in therapeutic drug development. However, because a drug molecule has to be water soluble to be readily delivered to the cellular membrane while retaining its hydrophobic properties, issues surrounding water insolubility can postpone – or completely derail – important new drug development. press.com your medical bookshop.

The most comprehensive resource on the topic, this second edition of Water Insoluble Drug Formulation brings together a distinguished team of experts to provide the scientific background and step-by-step guidance needed to deal with solubility issues in drug development.
Ciprofloxacin is a classic drug which is weakly basic and practically insoluble in water at neutral pH and most intravenous formulations contain lactic acid as pH modifiers to improve solubility . Intravenous ciprofloxacin infusions are essential for treating different kinds of severe bacterial infections.
Polymeric nanocarriers, are insoluble in both water and oil can be successfully formulated. lipid based formulations and crystal nanosuspensions have been Finally, the solid state of the drug results in increased stability described to improve the bioavailability in this case [1,2].
