It is possible that β-blockers work, at least partially, by some central action in the cardiovascular control centres of the brain.

Cytotoxic antibiotics prevent cell division by direct action on DNA or by inhibition of transcription of DNA to RNA, thus preventing protein synthesis. Plant derived drugs work in various ways. Vinca alkaloids inhibit formation of microtubules so that acyclovir cost ireland division is halted because the spindle cannot form. Taxanes have a similar effect by inhibition of breakdown of microtubules once the spindle has formed.
