Effect of molecular weight and concentration hyaluronan on the in-vitro release characteristics of ibuprofen and diclofenac sodium across cellulose membrane
Hyaluronan (HA) is a naturally occurring polyanionic glycosaminoglycan. Drugs formulated in HA and applied topically are retained in the skin with little systemic absorption (Brown et al 2000, 2001). However, the precise ...
A comparison of topical formulations for the prevention of human schistosomiasis
Recently, a dimeticone formulation has been shown to be effective at preventing Schistosoma cercariae infecting skin, while DEET (N,N-diethyl-m-toluamide), a highly effective insecticide, has been shown to have activity ...
Investigation of the stabilisation of freeze-dried lysozyme and the physical properties of the formulations
The long-term stability of a protein formulation requires that the glass transition temperature (T-g) of the formulation should be maximised and the perturbation of the protein native structure in the dried form after ...
Determination of polyvinylpyrrolidone using high-performance liquid chromatography
Polyvinylpyrrolidone (PVP) is a versatile polymer with innate surface activity. It is very difficult to accurately assay due to its wide molecular weight range and amphiphilic nature. This study evaluated a reversed-phase ...
