Researchers from Finland have found that the antidepressant drug fluvoxamine (brand names Fevarin, Faverin, Luvox etc.) drastically increases the concentrations of tizanidine (Sirdalud, Zanaflex) in blood.
Concomitant use of fluvoxamine and tizanidine results in severe and prolonged decrease in blood pressure and greatly enhanced central nervous system effects. This previously unrecognised interaction can be dangerous, particularly in elderly patients, and the concomitant use of the two agents must be avoided. Both fluvoxamine and tizanidine have been in wide clinical use for more than 10 years.
The concentrations of tizanidine in blood were increased on average 33-fold by fluvoxamine in a carefully controlled study in healthy volunteer subjects. The volunteers ingested the usual 100-mg dose of fluvoxamine or placebo daily for 4 days, and then a single 4-mg dose of tizanidine. The interaction was observed in each of the ten subjects; the smallest increase in tizanidine concentration by fluvoxamine was 14-fold, the greatest increase was 103-fold!

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
