Infectious disease model generalization based on diffuse perturbations under conditions of body's temperature reaction

The infectious disease mathematical model is generalized based on the influence of diffuse perturbations on the development of the disease under conditions of the body's temperature reaction. The singularly perturbed model problem was reduced with delay to a sequence of problems without delay, for which the corresponding asymptotic expansions of solutions are obtained. The presented results of computer modeling in various situational states illustrate the expected decrease in the growth rate of the number of viral particles as a result of the action of the body's protective temperature reaction. The results of numerical experiments demonstrate the influence of the diffuse effect of "scattering" of forcing factors on the dynamics of a viral disease under conditions of the body's temperature reaction are presented too. It is noted that the decrease of the model amount of antigens in the epicenter of infection to a non-critical level caused by diffuse "scattering" over a relatively short time period makes them further destroyed by immune agents presented in the body, or requires the introduction of an injection solution with a smaller amount of donor antibodies.

Cost analysis of migraine pharmacotherapy with selective 5HT1 receptor agonists in Ukraine

The cost analysis for the relief of migraine attack using selective 5HT1-receptor agonists (frovatriptan, zolmitriptan, risatriptan, sumatriptan) of domestic and imported manufacturers in various dosages and forms of production in the proposed resource online pharmacy chains of Lviv for their efficient and cost effective applications. Among the registered drugs, most dosage forms and trade names are presented for sumatriptan; slightly less for risatriptan and zolmitriptan; for frovatriptan is only one trade name. It has been found that to relieve migraine attack with domestic drugs will be cheaper for patients than imported. Packaging with the same dosage of active ingredient, but with more tablets in the blister is more cost effective for patients. It`s the most economical to stop the migraine attack with Stopmigren (sumatriptan) at a dosage of 50 mg, packing 6 tablets in a blister, and the most valuable drug is Rapimig (zolmitriptan) at a dosage of 50 mg, packing 6 tablets in a blister.
