The search for a miracle drug that would help to alleviate multiple ailments, dates back
many thousands of years before our era and continues until today. Various techniques have been used
to obtain a formulation, that would give the desired therapeutic effect. The most popular approach includes
drug coctails and multicomponent drugs. Polytherapy is widely accapted as an effective tool for
the treatment of several diseases, however it is often faced with important drawbacks that may sometimes
result in fatal adverse effects associated with unpredictable drug interactions. Conversly, hybrid
compounds were found to be an attractive way to counterbalance the unwanted side effects derived
from the administration of individual drug components. Futhermore, they can serve as effective and
improved remedies for patients suffering from several diseases simultaneously, as different receptorrelated
pharmacophores are used as structural components.
This review covers patent literature from 1980 till now that highlights the progress that has been made
in the discovery of hybrid compounds potentially useful in the treatment on various disorders, including
pain states, neurodegenerative or infectious diseases. Additionally, this review was further enriched
with findings from original research papers.
