DRUG PRODUCT
PERFORMANCE
(DPP)
DRUG PRODUCT PERFORMANCE
(DPP)
◦ DPP is defined as the release of the drug substance leading to
bioavailability of the drug substance.
◦ Assessment of DPP is important since bioavailability is related both
to the pharmacodynamics response and to adverse effects.
◦ DPP – determined by in-vivo bioequivalence studies or in-vitro by
comparative drug dissolution studies.
DRUG PRODUCT PERFORMANCE IN-VITRO
* Dissolution and drug release tests are conducted in-vitro to measure how quickly and how much of a
drug substance dissolves or released from a drug product, typically in an aqueous medium under
specific conditions.
* These test provide critical data throughout the drug development process.
• The dissolution test serve as a key quality control procedure, ensuring batch consistency and
identifying any variability in composition and manufacturing process.
• When linked to in-vitro performance, the dissolution and drug release to provide how well the drug
perform in the body.
• Ideally, the in-vitro dissolution method should closely simulate the drug release profile in -vivo and
should distinguish between formulation with varying release characteristics.
• The primary goal is to develop a dissolution test that can differentiate between acceptable and
suboptimal formulation by observing differences in dissolution rates under identical test conditions.
◦ A well-designed dissolution test should be sensitive enough to detect changes in formulation,
manufacturing process, or the physical and chemical properties of the drug, such as particle size,
polymorphism and surface area.
◦ Dissolution testing is often required for routine batch testing and assessing changes made during scale
up or after regulatory approval (SUPAC) for marketed products.
◦ For minor changes, the effect on in-vivo performance can be evaluated by comparing dissolution
profiles of the product before and after the modification using the approved dissolution method or
testing under different pH condition.
◦ Major post approval changes in the manufacturing process may require bioequivalence studies,
although this requirement may be waived if there is an acceptable in vitro- in vivo correlation.
◦ The dissolution test should be robust, reproducible and transferable between laboratories to ensure
consistency.
DRUG PRODUCT PERFORMANCE IN-VIVO:
* In-vivo drug product performance refers to the release of the drug substance
from the product and its subsequent bioavailability.
* Evaluating in-vivo performance is critical because bioavailability affects the
pharmacodynamic response and any potential adverse events.
* Therefore, performance tests link the quality of a drug product to its clinical
safety and efficacy.
* Bioavailability and bioequivalence studies are key measures of a drug’s in-
vivo
performance.
• These studies are essential for both new and generic drug development.
Bioavailability studies assess the impact of changes in the drug’s physicochemical
properties, formulation and manufacturing process on performance. They ensure the new
drug product performs similarly to the original formulation used in clinical safety and
efficacy trails.
Bioequivalence studies compare the bioavailability of test drug product to that of a
reference product with the same active ingredients.
In general, in-vivo bioequivalence is demonstrated in healthy volunteers, though under
specific circumstances, in-vitro methods like comparative dissolution profiles can be used.
During drug development, bioequivalence studies compare formulation across early and
late clinical trails, between formulations and those intended for market or among different
strengths of a product.
Bioequivalence studies also support new formulations of previously approved drugs, such
as fixed dose combinations or modified release drugs.
Post approval in-vivo bioequivalence studies may be necessary for major formulation,
manufacturing , or site changes, to ensure the marketed drug product continues to perform as
expected.
The drug product approved by the FDA may differ from the original formulation tested in
clinical trials and any post approval changes known as SUPAC require the manufacturer to
demonstrate equivalent drug performance.
For generic drugs, bioequivalence studies are essential for regulatory approval, as clinical
safety and efficacy trials are not typically conducted for generics.
Generic drug manufacturers must demonstrate that their products are pharmaceutically
equivalent, bioequivalent and therapeutically equivalent to the reference brand name drug ,
typically through in-vivo bioequivalence studies under both fasting and fed conditions.

ASSESSMENT
BIOEQUIVALENCE AND DRUG
PRODUCT ASSESSMENT
By World Health Organization (WHO):
Two pharmaceutical products are bioequivalent if they are
pharmaceutically equivalent , and their bioavailabilities, in terms
of rate (Cmax and tmax) and extent of absorption (area under
the curve), after administration of the same molar dose under the
same conditions, are similar to such a degree that their effects can
be expected to be essentially the same.
NEED OF BIOEQUIVALENCE
◦ The need of bioequivalence studies is increasing due to the
large growth of the production and consumption of generic
product
Bioequivalence studies are conducted if there is :
◦ A risk of bio inequivalence or
◦ A risk of pharmacotherapeutic failure
◦ No clinical studies have been performed in patient with the
generic product to support its efficacy and safety
TYPES OF EQUIVALENCE
1. Chemical equivalence
Two or more drug product contain same labelled chemical in a same amount.
2. Pharmaceutical equivalence
Two or more drug are identical in strength, quality, purity, content uniformity,
disintegration and dissolution.
3. Therapeutic equivalence
Indicate that two or more drug product that contain the same therapeutically
active ingredient elicit identical pharmacological effect and control the disease
to the same extent.
4. Bioequivalence
It is a relative term which denotes that the drug substance in two or more
identical dosage form, reaches the systemic circulation at the same relative
rate and relative extent.
DESIGN AND EVALUATION OF
BIOEQUIVALENCE STUDIES

BIOWAIVERS
o The term Biowaiver is applied to a drug regulatory approval process when a dossier
(application) is approved based on the evidence of Bioequivalence.
o The biowaiver means that the in vivo bioavailability and bioequivalence studies may
be waived (i.e not necessary for the product approval)
o In 1995 , US department of Health and Human Services , and US-FDA started the
Biopharmaceutical Classification System ,with the aim of granting so called
Biowaivers for SUPAC.
o Applicant can request biowaiver for immediate release product based on an
approach termed the biopharmaceutics classification system BCS (32).
 The BCS is a framework for classifying drug substances
based on solubility and intestinal permeability.
 The BCS classifes drug substances as:
SCALE-UP PROCESS APPROVAL CHANGES
◦ The scale-up process approval changes made after approval in
the composition, Manufacturing process, mfg. equipment &
change of site have become known as Scale-up and Post
Approval Changes.
◦ Abbreviated as SUPAC.
NDA → Larger Batch Size
ANDA → Larger Batch Size
SCALE-UP POST APPROVAL
CHANGES
◦ The FDA has issued various guidance for SUPAC. They are
SUPAC – IR
(For Immediate-release solid oral dosage form)
SUPAC – MR
(For Modified-release Solid oral dosage form)
SUPAC – SS
(For Non-sterile semisolid dosage form such as creams, ointments,
gels & lotions)
POST MARKETING SURVEILLANCE
(PMS)
◦ PMS is the practice of monitoring the safety of a pharmaceutical drug
or medical device after it has been released on the market.
◦ It is an important part of the science of Pharmacovigilance.
Objective:
To develop information about drug effects under customary
condition of drug use.

    Bioavailability studies assessthe impact of changes in the drug’s physicochemical properties, formulation and manufacturing process on performance. They ensure the new drug product performs similarly to the original formulation used in clinical safety and efficacy trails. Bioequivalence studies compare the bioavailability of test drug product to that of a reference product with the same active ingredients. In general, in-vivo bioequivalence is demonstrated in healthy volunteers, though under specific circumstances, in-vitro methods like comparative dissolution profiles can be used. During drug development, bioequivalence studies compare formulation across early and late clinical trails, between formulations and those intended for market or among different strengths of a product. Bioequivalence studies also support new formulations of previously approved drugs, such as fixed dose combinations or modified release drugs.

    Post approval in-vivobioequivalence studies may be necessary for major formulation, manufacturing , or site changes, to ensure the marketed drug product continues to perform as expected. The drug product approved by the FDA may differ from the original formulation tested in clinical trials and any post approval changes known as SUPAC require the manufacturer to demonstrate equivalent drug performance. For generic drugs, bioequivalence studies are essential for regulatory approval, as clinical safety and efficacy trials are not typically conducted for generics. Generic drug manufacturers must demonstrate that their products are pharmaceutically equivalent, bioequivalent and therapeutically equivalent to the reference brand name drug , typically through in-vivo bioequivalence studies under both fasting and fed conditions.

    BIOEQUIVALENCE AND DRUG PRODUCTASSESSMENT By World Health Organization (WHO): Two pharmaceutical products are bioequivalent if they are pharmaceutically equivalent , and their bioavailabilities, in terms of rate (Cmax and tmax) and extent of absorption (area under the curve), after administration of the same molar dose under the same conditions, are similar to such a degree that their effects can be expected to be essentially the same.
  • 54.
    NEED OF BIOEQUIVALENCE ◦The need of bioequivalence studies is increasing due to the large growth of the production and consumption of generic product Bioequivalence studies are conducted if there is : ◦ A risk of bio inequivalence or ◦ A risk of pharmacotherapeutic failure ◦ No clinical studies have been performed in patient with the generic product to support its efficacy and safety
  • 55.
    TYPES OF EQUIVALENCE 1.Chemical equivalence Two or more drug product contain same labelled chemical in a same amount. 2. Pharmaceutical equivalence Two or more drug are identical in strength, quality, purity, content uniformity, disintegration and dissolution. 3. Therapeutic equivalence Indicate that two or more drug product that contain the same therapeutically active ingredient elicit identical pharmacological effect and control the disease to the same extent. 4. Bioequivalence It is a relative term which denotes that the drug substance in two or more identical dosage form, reaches the systemic circulation at the same relative rate and relative extent.
  • 56.
    DESIGN AND EVALUATIONOF BIOEQUIVALENCE STUDIES Fasting study • Use for immediate release and modified release oral dosage form • Overnight fast and 4 hour after dosing Food intervention study • Co-administration of food with an oral drug product may affect the bioavailability of drug Multiple dose study • Multiple dose, randomized, crossover study • Three consecutive Trough concentration on three consecutive days
  • 57.
    TYPE OF DESIGN 1.Completerandomized design All treatment are randomly allocated among all experimental subject. example: if there is 20 subjects, number them from 1 to20. Random select non repeating number 2. Randomized block designs Subjects are sorted into homogenous group called blocks. Method Subjects having similar background characteristics are formed as blocks
  • 58.
    EVALUATION OF DATA Analytical data -Analytical method for measurement of drug must be validated for accuracy, precision, sensitivity and specificity. -More then one method during bioequivalence study may not be valid because different methods may yield different values.

    SCALE-UP PROCESS APPROVALCHANGES ◦ The scale-up process approval changes made after approval in the composition, Manufacturing process, mfg. equipment & change of site have become known as Scale-up and Post Approval Changes. ◦ Abbreviated as SUPAC. NDA → Larger Batch Size ANDA → Larger Batch Size
  • 63.
    SCALE-UP POST APPROVAL CHANGES ◦The FDA has issued various guidance for SUPAC. They are SUPAC – IR (For Immediate-release solid oral dosage form) SUPAC – MR (For Modified-release Solid oral dosage form) SUPAC – SS (For Non-sterile semisolid dosage form such as creams, ointments, gels & lotions)

    POST MARKETING SURVEILLANCE (PMS) ◦PMS is the practice of monitoring the safety of a pharmaceutical drug or medical device after it has been released on the market. ◦ It is an important part of the science of Pharmacovigilance. Objective: To develop information about drug effects under customary condition of drug use. To assess a known serious risk related to the use of drug ◦ Advantages: Helps to detect rare ADR’s  Drug interaction
  • 65.
    METHODS OF SURVEILLANCE: Fourtypes of studies are generally are used to identify drug effects 1. Controlled clinical trials 2. Spontaneous & Voluntary recording 3. Cohort studies 4. Case Control studies
  • 66.
    SOURCES OF PMS 1.Customer surveys 2. Literature reviews 3. Expert user groups 4. Customer complaints 5. The media
