The high/low solubility classification using MLogSM or MSol is novel and independent of traditionally used dose number criteria.
The present study assessed whether intravenous (IV) nicotine would condition a place preference in an unbiased design and evaluated important behavioral parameters: nicotine dose, number of conditioning trials, and infusion-to-placement interval.
The practical logistics on pre-experimental planning, scheme/design/layout, and precautions in terms of dose number, dose range, dose density, drug combination ratio, conservation of laboratory animals as well as regulatory and cost-effective considerations have been presented.
Those include dose, number of angular projections, and the total angular span of those projections.
In order to reduce this radiation effects, low electron dose (number of electrons per area) techniques can be implemented.
The Dose Number, Do, provides a measure of the impact of drug solubility on dissolution, vis: Do=frac{M_0/{V}_0}{C_s} (1).
Amidon et al. (Amidon et al. 1995) derived two dimensionless numbers (i.e., the dose number, Do and the Dissolution Number, Dn) that were used to assess drug dissolution.
In this study, all diode and ionization chamber measurements were done three times, and their average values were reported as the dose number to reduce statistical errors.
BCS 2 drugs have low equilibrium solubility values between pH 1 and 6.8 and a high dose number and low dissolution number.
The dose number for currently marketed inhaled drugs identified only a few solubility-limited compounds/classes and dissolution number can be modified through formulation approaches.
