Why is therapeutic equivalence important?
It allows users to determine quickly whether the Agency has evaluated a particular approved product as therapeutically equivalent to other pharmaceutically equivalent products and provides additional information on the basis of the FDA’s evaluations.

What is the meaning of therapeutic equivalence quizlet?
– Therapeutic equivalence occurs when two drugs are bioequivalent, have the same active ingredient, and have the same strength, dosage form, and route of administration. – A brand name drug and its generic counterpart with the same dosage form, strength, and route of administration are therapeutic equivalents.
What does therapeutically equivalent mean?
Approved drug products are considered to be therapeutic equivalents if they are pharmaceutical equivalents for which bioequivalence has been demonstrated, and they can be expected to have the same clinical effect and safety profile when administered to patients under the conditions specified in the labeling.
What are the benefits of a therapeutic interchange?
Therapeutic interchange programs enable pharmacy managers to neutralize or at least slow the rate of drug cost increases, ensuring appropriate utilization of resources and more favorable patient outcomes.
What is the difference between generic substitution and therapeutic substitution?
In generic substitution, a generic drug is substituted for a brand name drug. However, both drugs have the same active chemical ingredient, same dosage strength, and same dosage form. Therapeutic substitution occurs when a pharmacist substitutes a chemically different drug for the drug that the physician prescribed.
What is pharmaceutical substitution?
Therapeutic substitution occurs when a pharmacist substitutes a chemically different drug for the drug that the physician prescribed. The drug substituted by the pharmacist belongs to the same pharmacologic class and/or to the same therapeutic class.
What is a therapeutic interchange?
Therapeutic interchange is the practice of replacing, with the prescribing practitioner’s approval, a prescription medication originally prescribed for a patient with an alternative prescription medication.
What is chemical equivalence in pharmacology?

What is generic substitution?
Commonly known as “generic substitution,” every state has evolved a process to overcome the “antisubstitution” laws that proliferated during the late 1940s. Antisubstitution may still be in place, but beginning in the early 1970s, every state enacted legislation for providing equivalent lower cost medication. States are highly variable in the precise details, but this often involves reference to FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (aka Orange Book). “Therapeutic equivalent” means that the product is approved by the FDA [new drug application (NDA) or abbreviated new drug application (ANDA)], it is pharmaceutically equivalent, and it is bioequivalent to the brand name product. However, it is important to note that the Orange Book is only a reference guide, FDA does not dictate the process for generic substitution; this is left to the individual states.
What is a phase 3 biosimilar?
Phase III clinical trials comparing biosimilars with their respective reference originators are clinical studies designed to assess therapeutic equivalence, at variance with conventional randomized controlled trials that are designed to demonstrate superiority of one treatment compared to another. In the setting of biosimilar development, the appropriate design of therapeutic equivalence studies is faced with a number of methodological challenges. When implementing an equivalence study, the classical rigorous ‘intention-to-treat’ approach – relying on the concept that more patients leaving an intervention arm due to the occurrence of adverse events would represent a bias in favor of the other treatment, if the analyses were limited only to the patients that completed the protocol – would on the contrary bias toward the conclusion that the biosimilar is equivalent. For this reason, it is recommended that equivalence studies for biosimilars should perform ‘per protocol’ analyses and present their data with 95% confidence intervals for a difference, rather than with a single p value. In particular, equivalence could be declared, according to the generally accepted standard, if the confidence intervals of the comparator compound (the biosimilar product) lie within ±15% of those estimated for the reference compound (the originator product) [47].
Is epilepsy a chronic disease?
Epilepsy being a chronic disease requires years long duration of treatment and in many cases life-long management at outpatient basis. Hence, it stands as a strong candidate for pharmacists to contribute especially in community settings including:
Do TE studies need CE?
TE studies with CE are currently required by the US FDA and HC for a generic submission of OIPs. Based on the step-wise approach, the EU would require such studies only when the in vitro and/or PK studies do not show equivalence. A vital element of a TE study with CE is the demonstration of a dose–response relationship, in order to confirm that a lack of difference in the CE is truly because the test and reference generate a similar level of effect, and not because the study lacks sensitivity in detecting a difference. This has been a major challenge, especially for products such as ICS, and is discussed further below.
