فرمولاسیون و بررسی خصوصیات پراکندگی های جامد پیروکسیکام تهیه شده با پلی اتیلن گلیکول 4000 و توئین 40
Background and purpose: Piroxicam is a non-steroidal anti- inflammatory drug that is characterized by low solubility and high permeability. According to the biopharmaceutic drug classification system, piroxicam is a class 2 drug with low solubility and high permeability. The solid dispersion, ammroach is commonly used to improve the dissolution of poorly water soluble drugs using hydrophilic po...
Background and purpose: Solubility behavior of a drug is one of the key determinants of its oral bioavailability. The bioavailability may be enhanced by increasing the solubility and dissolution rate of drug by combining the drug with a hydrophilic carrier. Naproxen is a poor water non-soluble analgesic and anti- inflammatory drug. A possible way of overcoming the naproxen low aqueous solubilit...
We consider an optical resonator containing a photonic crystal fiber and driven coherently by injected beam. This device is described generalized Lugiato-Lefever equation with fourth-order dispersion. use asymptotic approach to derive interaction equations governing the slow time evolution of coordinates two interacting dissipative solitons. show that Cherenkov radiation induced positive disper...
The computation of intermolecular interaction energies via commonly used density functionals is hindered by their inaccurate inclusion of medium and long range dispersion interactions. Practical computation of inter- and intra-macrobiomolecule interaction energies, in particular, requires a fairly accurate yet not overly expensive methodology. It is also desirable to compute intermolecular ener...
