资治通鉴白话文Mucoadhesive preparations DEFINITION Mucoadhesive preparations contain one or more active substances intended for systemic absorption through the buccal mucosa over a prolonged
period
of time.They may be supplied as mucoadhesive buccal tablets or as other mucoadhesive solid or mi-solid preparations.Mucoadhesive buccal tablets are prepared by compression
of mono-or multi-layered
tablets.They usually contain
hydrophilic polymers,which on wetting with the saliva
produce a flexible hydrogel that adheres to the buccal mucosa.PRODUCTION In the manufacture of mucoadhesive buccal tablets,measures are taken to ensure that they posss suitable
mechanical strength to resist handling without crumbling or breaking.This may be
demonstrated
by examining the Friability of uncoated tablets (2.9.7)and the Resistance to crushing of tablets (2.9.8).TESTS Dissolution .
Unless
otherwi
justified and authorid,a suitable test is carried out to demonstrate the appropriate relea of the active substance(s).01/2008:0520PARENTERAL PREPARATIONS Parenteralia The requirements
of this monograph do not necessarily apply to products derived from
human blood,to
immunological preparations,or radiopharmaceutical preparations.Special requirements may apply to preparations for veterinary u depending on the species of animal for which the preparation is intended.DEFINITION Parenteral preparations are sterile
preparations intended for administration by injection,infusion or implantation into the human or animal body.Parenteral preparations may require the u of excipients,for example to make the preparation isotonic with respect to blood,to adjust
the pH,to increa solubility,to prevent deterioration of the active
substances
or to provide
adequate
antimicrobial properties,but not to adverly affect the intended medicinal action of the preparation or,at the concentrations ud,to cau toxicity or undue local irritation.Containers for parenteral preparations are made as far as possible from
materials
that are sufficiently transparent
to permit the visual inspection of the contents,except for implants and in other justified and authorid cas.Where applicable,
the containers for parenteral preparations comply with the requirements for Materials ud for the manufacture of containers (3.1and subctions)and Containers (3.2and subctions).Parenteral preparations are supplied in glass containers (3.2.1
)or in other containers such as plastic containers (3.2.2,3.2.2.1and 3.2.9)and prefilled syringes.The tightness of the container
is ensured by
suitable
means.Closures
ensure a good al,prevent the access of micro-organisms and other contaminants and usually permit the withdrawal of
a part or the whole of the contents without removal of the closure.The plastic
materials or elastomers (3.2.9)ud to manufacture the closures are sufficiently firm and elastic to allow the passage of a needle with the least possible shedding of
particles.Closures for multido containers are
sufficiently elastic to ensure that the puncture is realed
when the needle is withdrawn.Several
categories of parenteral preparations may be distinguished:—injections,
—infusions,
—concentrates for injections or infusions,
—powders for injections or infusions,
锦母角—gels for injections,
—implants.
PRODUCTION
During
the development
of a parenteral preparation,the
formulation for which contains an antimicrobial prervative,the effectiveness of the chon prervative shall be demonstrated
to the satisfaction of the competent authority.A suitable test method together
with
criteria for
judging
the prervative properties of the formulation are provided under Efficacy of antimicrobial prervation (5.1.3).
Parenteral preparations are prepared using materials and methods designed to ensure sterility and to avoid
the introduction of contaminants and the
growth of
micro-organisms.Recommendations on this aspect are
provided in the text on Methods of preparation of sterile products (5.1.1).Water ud in the manufacture of parenteral preparations
complies with the requirements of water for injections in bulk stated in the monograph on Water for injections (0169).
TESTS
Particulate contamination:sub-visible particles (2.9.19).
For preparations for human u,solutions for infusion or
solutions for injection comply with the test.In
the ca of preparations for subcutaneous or intramuscular injection,higher limits may be appropriate.Radiopharmaceutical preparations are exempt from the requirements.Preparations for which the label states that
the product is to be ud with a final filter are exempt from the requirements,providing it has been demonstrated that the filter delivers a solution that complies with the test.
For preparations for veterinary u,when
supplied in containers with a nominal content of more than 100ml and when the content is equivalent to a do of more than

Injections
DEFINITION
Injections are sterile solutions,emulsions or suspensions. They are prepared by dissolving,emulsifying or suspending the active substance(s)and any added excipients in water,in a suitable non-aqueous liquid,that may be non-sterile where justified,or in a mixture of the vehicles.
Solutions for injection,examined under suitable conditions of visibility,are clear and practically free fro
m particles. Emulsions for injection do not show any evidence of pha paration.Suspensions for injection may show a diment which is readily disperd on shaking to give a suspension which remains sufficiently stable to enable the correct do to be withdrawn.
Multido preparations.Multido aqueous injections contain a suitable antimicrobial prervative at an appropriate concentration except when the preparation itlf has adequate antimicrobial properties.When a preparation for parenteral u is prented in a multido container, the precautions to be taken for its administration and more particularly for its storage between successive withdrawals are given.
Antimicrobial prervatives.Aqueous preparations which are prepared using aptic precautions and which cannot be terminally sterilid may contain a suitable antimicrobial prervative in an appropriate concentration.
No antimicrobial prervative is added when:
—the volume to be injected in a single do exceeds15ml, unless otherwi justified,
—the preparation is intended for administration by routes where,for medical reasons,an antimicrobial prervative is not acceptable,such as intracisternally,epidurally,
intrathecally or by any route giving access to the
cerebrospinal fluid,or intra-or retro-ocularly.
Such preparations are prented in single-do containers.
PRODUCTION
In the manufacture of injections containing disperd particles,measures are taken to ensure a suitable and controlled particle size with regard to the intended u. Single-do preparations.The volume of the injection in a single-do container is sufficient to permit the withdrawal and administration of the nominal do using a normal technique(2.9.17).
TESTS
Uniformity of dosage units.Single-do suspensions for injection comply with the test for uniformity of dosage units (2.9.40)or,where justified and authorid,with the test for uniformity of content shown below.Herbal drugs and herbal drug preparations prent in the dosage form are not subject to the provisions of this paragraph.
Uniformity of content(2.9.6).Unless otherwi prescribed or justified and authorid,single-do suspensions for injection with a content of active substance less than2mg or less than2per cent of the total mass comply with test A for uniformity of content of single-do preparations.If
the preparation contains more than one active substance, the requirement applies only to tho substances that correspond to the above conditions.Bacterial endotoxins-pyrogens.A test for bacterial endotoxins(2.6.14)is carried out or,where justified and authorid,the test for pyrogens(2.6.8).Recommendations on the limits for bacterial endotoxins are given in chapter2.6.14.
Preparations for human u.The preparation complies with a test for bacterial endotoxins(2.6.14)or with the test for pyrogens(2.6.8).
Preparations for veterinary u.When the volume to be injected in a single do is15ml or more and is equivalent to a do of0.2ml or more per kilogram of body mass,the preparation complies with a test for bacterial endotoxins (2.6.14)or with the test for pyrogens(2.6.8).

DEFINITION
王杰新歌
Transdermal patches are flexible pharmaceutical preparations of varying sizes,containing one or more active
substances.They
are intended
to be applied to the unbroken
skin in order to deliver the active substance(s)to the systemic
circulation after passing through the skin barrier.Transdermal
patches normally consist of an outer covering which supports a preparation which contains the active
substance(s).The transdermal patches are covered on the
site of the relea surface of the preparation by a protective liner,which is removed before applying the patch to the skin.
The outer covering is a backing sheet impermeable to the active substance(s)and normally impermeable to water,designed to support and protect the preparation.The outer covering may have the same dimensions as the preparation or it may be larger.In the latter ca the overlapping border of the outer covering is covered by pressure-nsitive adhesive substances which assure the adhesion of the patch
to the skin.
The preparation contains the active substance(s)together
with excipients such as stabilirs,solubilirs or substances intended to modify the relea rate or to enhance transdermal absorption.It may be a single layer or multi-layer solid or
mi-solid matrix,and in this ca it is the composition
and structure of the matrix which determines the diffusion pattern of the active substance(s)to the skin.The matrix may contain pressure-nsitive adhesives which assure the
adhesion of the preparation to the skin.The preparation may exist as a mi-solid rervoir one side of which is a
membrane
which may control the relea and the diffusion of the active substance(s)from the preparation.The pressure-nsitive adhesive substances may,in this ca,be
applied to some or all parts of the membrane,or only around
the border of the membrane of the outer covering.When applied to the dried,clean and unbroken
skin,the
transdermal
patch adheres firmly to the skin by gentle pressure of the hand or the fingers and can be peeled off
without causing appreciable injury to the skin or detachment of the
preparation from the outer covering.The patch must
not be irritant or nsitising to the skin,even after repeated applications.The protective liner generally consists of a sheet of plastic or
metal material.When removed,the protective liner does not
detach the preparation (matrix or rervoir)or the adhesive from the patch.Transdermal patches are normally individually enclod in aled sachets.半身像
