The velocity of release of IVM from CR preparation depended on the change in solubility of IVM by additives, and in the case of a formulation with addition of desoxycholate sodium, linear in vitro release of IVM was observed over a period of 1 year.
This clearly indicates that improving the dispersibility of a formulation by addition of surfactants does not necessarily improve the in vivo performance of the formulation.
Similar maxima were observed in the case of samples of AA liposomal formulation after addition of sulphuric acid as an esterification accelerator (Fig. 2c).
Using optimized formulation design, addition of l-arginine chloride to a sucrose-based formulation provided elegant cakes and benefits for protein stability.
The development of more immunogenic vaccines through new formulations or addition of adjuvants holds the promise of revolutionizing delivery and improving efficacy.
An experimental formula of the 'Alethea' technology (Plant Impact PLC, Harpenden, UK) was applied to four-week old tomato seedlings at a concentration of 99 1 v/v (distilled H2O Alethea) as per manufacturer's instructions (see Additional file 1 for a detailed description of the Alethea formulation), in addition to an equal quantity of control plants, which were sprayed with distilled H2O.
Briefly, 100 μL of sterile sodium pertechnetate in saline (containing approx. 74-110 MBq of 99mTcO4− obtained by solvent extraction method from Molybdenum) was added to 100 μL (1 mg/mL) of each formulation followed by addition of 50 μL stannous chloride (2 mg/mL in 10% glacial acetic acid); pH was adjusted to 6.5 using 0.1 M NaOH, and the resulting solution was incubated at 37˚C for 15 mins.
For both formulations, the addition of vitamin increased the viscosity of the formulations.
In addition, mere formulation of a licensed split-subunit vaccine significantly enhanced its immunogenicity.
Formulation of ASDs typically involves the addition of polymers to raise the Tg, enhance the dissolution, and protect the drug from crystallizing.
