Ingredients
A VTM is the abstract conceptual
representation of the material defining the
prescriber's therapeutic intent, divorced from
formulation, dose or strength.
List of ingredients and excipients .
Note Within the file of ingredient substances will
be entries relating to the following:1) Complete substances which act as actual
ingredients of medicinal products. For example:
heparin sodium or cyclizine lactate (as distinct from
heparin and cyclizine). This class of substances
may or may not be a salt or other type of
derivative.-
A VTM cannot exist unless it is linked to a VMP
Name
The current name in short and full forms
VMP_Ingredient
Links VMP to the set of active ingredients
common to the AMPs linked to the VMP
VMP_VTM
Links a set of VMPs to a VTM
A VMP that is a drug may not
be linked to a VTM or it may
be linked to one VTM.
Each VTM must be attached to
one or more VMPs
DoseForm
Dictionary of terms for the
physical conformation of the
drug as normally dispensed.
A Dose Form may be
orphaned from any VMP
Name
A description of the dose form.
VMP
VMP_Form
Links a VMP to its dose form.
Every VMP that is a drug has exactly
one dose form.
A dose form may not be linked to a
VMP or it may be linked to one
or many
A VMP is the conceptual representation of one or more clinically equivalent Actual
Medicinal Products the purpose of which is to support the representation of the
fundamental reality of the concept. Its core description requires product name, strength
and dosage form, but is devoid of explicit or implicit information attributable to
manufacturer or pack.
2) Base substances which may or may not be
available as actual ingredients. For example,
heparin or cyclizine.
For each link the quantity of the ingredient or
of its base is stored.
An ingredient may be orphaned from any VMP or
AMP or from another parent or base ingredient.
A VMP may have no ingredients attached or
it may have one or more.
Name
Name of the ingredient - no history or short forms
An ingredient may not be be attached to any
VMP or it may be attached to one or more.
Base Ingredient
For salts etc a recursive pointer to the base
ingredient.
Strength
An indication of the quantity of the ingredient
in the product
AMP_Ingredient
Links AMPs to ingredients marked as
“Interesting Excipients”.
The quantity of ingredient is not stored.
An AMP may be linked to no ingredients
or to one or more.
AMP
An ingredient may not be linked to any
AMP or it may be linked to one or more.
An AMP is the representation of a single unit dose of a medicinal product that is (or has
been) made or marketed by a specific manufacturer or supplier. Its core description
requires product name, strength, dosage form and manufacturer, but is devoid of
explicit information attributable to pack size.
Strength Basis
An indication of whether the strength refers
to the ingredient or its base
The unit dose is the smallest single entity of the product that can be physically
handled with the following defined deviations:
Continuous liquids excluding eye-drops: where the unit dose is expressed in
terms of the accepted normal sub-unit used as the basis of administration
AMP_Suppliers
Links a set of AMPs to the company that
supplies them.
Each AMP is supplied by one and
only one supplier.
A Supplier may not have any AMPs or it may
have one or more products.
Suppliers
A list of Suppliers of medicinal products. The name
used will be that which appears on the product
package and may be a manufacturer, a wholesaler
or a marketing agent.
Continuous solids: where the unit dose is expressed in terms of the accepted
normal sub-unit used as the basis of administration
A VMP cannot exist unless it is linked to one or more AMPs and to one or more VMPPs
Continuous semi-solids and eye-drops: where a consistent, physically
measurable unit or sub-unit cannot be defined and which is therefore not
instantiated.
Name

source of the name, a previous name and reasons for change
AMP_VMP
HideName
If this flag is set the name is hidden from view
A VMP must be linked to at least one AMP and can be linked to several AMPs
Links a set of AMPs to their corresponding VMP
An AMP must have a VMP but only one VMP
An AMP cannot exist unless it is linked to one or more AMPPs
Name
The current name in full and short Semantic Normal Form, a previous value and reason
for change. Each flavour of a AMP has a separate entry.
Prescribability
Indicates if product should not be prescribed by VMP
Freeness
A set of flags indicating if VMP is sugar free, CFC free etc.
Regulation
Information on regulatory restrictions and rules about the product such as Controlled
Drug Schedule
Component Flag
Indicates if the product is normal, a compound product or a constituent product.
VMPP_VMP
Availability
The licence and “specials” status.
Route
AMP_Route
Regulation
Information on reglatory restrictions and rules about the product such as CSM
notification.
Links an AMP to the set of routes that have
been licensed for the product.
Reimbursement
Information on reimbursement
An AMP may have no linked Routes or it may
have one or more routes.
Component Flag
Indicates if the product is normal, a compound product or a constituent product.
VMP_Route
Links VMP to the set of licensed routes
common to the AMPs linked to the VMP.
A VMP may have no routes linked, or it
may be linked to one o r more routes.
A route may not be linked to any VMP or
it may be linked to one or more VMPs
A VMPP is linked to one and
only one VMP
A VMP must have one or
more VMPPs
A licensed route of administration
of a medicinal product.
A route may be orphaned from any
VMP or AMP.
Name
Description of the route of
administration
A route may not be linked to any AMP or
it may be linked to one or more AMPs
AMPP_AMP
Links a set of AMPPs to
their “parent” AMP.
Each AMPP must link to
one and only one AMP.
Each AMP must have one
or more AMPPs
AMPP
VMPP
A VMPP is the conceptual representation of each and every AMPP that exists for the
linked AMPs. This includes a conceptual representation of AMPPs that exist to
represent the components of a compound AMPP.
An AMPP is the representation of each and every saleable/available pack (container of
dose units) of an AMP, in terms of description of quantity, of how many 'dose units' of
the AMP (or weight, for solids and semi-solids) are present in the pack.
AMPP_VMPP

conceptual form or it may also be a saleable/available AMPP.
An AMPP cannot exist without a parent AMP

An AMP is the representation of a single unit dose of a medicinal product that is (or has
been) made or marketed by a specific manufacturer or supplier. Its core description
requires product name, strength, dosage form and manufacturer, but is devoid of
explicit information attributable to pack size.
VMP
A VMP is the conceptual representation of one or more clinically equivalent Actual
Medicinal Products the purpose of which is to support the representation of the
fundamental reality of the concept. Its core description requires product name, strength
and dosage form, but is devoid of explicit or implicit information attributable to
manufacturer or pack.
The unit dose is the smallest single entity of the product that can be physically
handled with the following defined deviations:
Continuous liquids excluding eye-drops: where the unit dose is expressed in
terms of the accepted normal sub-unit used as the basis of administration
Continuous solids: where the unit dose is expressed in terms of the accepted
normal sub-unit used as the basis of administration
A VMP cannot exist unless it is linked to one or more AMPs and to one or more VMPPs

VMPP
A VMPP is the conceptual representation of each and every AMPP that exists for the
linked AMPs. This includes a conceptual representation of AMPPs that exist to
represent the components of a compound AMPP.

dose units) of an AMP, in terms of description of quantity, of how many 'dose units' of
the AMP (or weight, for solids and semi-solids) are present in the pack.

An AMPP may also be the representation of the number of “dose units” of an AMP
present as a constituent of a compound pack. This constituent pack may exist only in a
conceptual form or it may also be a saleable/available AMPP.
An AMPP cannot exist without a parent AMP
