Combination therapy may seem costlier than monotherapy in the short term, but when it is used appropriately, it causes significant savings: lower treatment
failure rate
, lower case-fatality ratios, fewer side-effects than monotherapy, slower development of resistance, and thus less money needed for the development of …
Why is combination therapy more effective than single drug therapy?
One rationale behind the success of combination therapies lies in their
ability to effectively influence biological regulatory circuits
, which have built-in redundancies that make them resistant to single perturbations, as well as feedback mechanisms that enable them to adapt to changes in the environment and maintain …
What is the benefit of combination therapy?
Combination therapy has been shown to dramatically
reduce the likelihood of drug resistance
(many drug-resistant mutations are mutually exclusive) and to suppress viral replication to the point that progression to AIDS is significantly slowed.
Why would doctors use combination therapy?
The rationale for combination therapy is
to use drugs that work by different mechanisms, thereby decreasing the likelihood that resistant cancer cells will develop
. When drugs with different effects are combined, each drug can be used at its optimal dose, without intolerable side effects.
Why is a combination of drugs most effective?
The use of drugs in combination can produce a
synergistic effect
if each of the drugs impinges on a different target or signaling pathway that results in reduction of required drug concentrations for each individual drug. Therefore, use of drug combinations could increase the success rate of drug repurposing screens.
Why Antibiotics are given in combination?
Combination therapy is mostly practiced because of one or more of the following reasons:
Broadening antibacterial spectrum
. Use of more than one agent broadens the antibacterial spectrum of the empirical therapy and thus ensures that at least one agent will cover the infecting organism.
Why combination therapy is used in tuberculosis?
Treating a tuberculosis patient with a monotherapy of rifampicin rapidly leads to resistance to the drug even if it is given for short periods only. In combination drugs,
the presence of isoniazid reduces the probability for the survival of rifampicin-resistant mutants
.
What treatments or combination of treatments are most effective?
Research generally shows that
psychotherapy
is more effective than medications, and that adding medications does not significantly improve outcomes from psychotherapy alone.
What is the best combination of antidepressants?
Using fluoxetine as the reference medication, the researchers analyzed various second-generation antidepressants. Sertraline and escitalopram had the best combination of efficacy and acceptability.
Why is chemo so painful?

Aspirin/paracetamol/caffeine
.
Atoltivimab/maftivimab/odesivimab
.
Carbidopa/levodopa/entacapone
.
When two or more drugs are used in combination to increase the pharmacological action is known as?
Two or more drugs that individually produce overtly similar effects will sometimes display greatly enhanced effects when given in combination. When the combined effect is greater than that predicted by their individual potencies, the combination is said to be
synergistic
.
What antibiotics should not be used together?

- Fluoroquinolones.
Can I combine two antibiotics together?
The effectiveness of antibiotics can be altered by combining them with each other
, non-antibiotic drugs or even with food additives. Depending on the bacterial species, some combinations stop antibiotics from working to their full potential whilst others begin to defeat antibiotic resistance, report researchers.
