1. What are sterile dosage forms

o
o
o
A dosage form is said to be sterile
when it is free from,
Microrganism,
Pathogens and
Spores

In short must be free from all types of
Microbial contamination.

Sterile products are mostly injected,
applied onto eye and administer
intranasally.

4.1.1 Ophthalmic Insitu gels

These type of systems can be formulated as drug-containing liquids suitable for
administration by instillation into the eye, which upon exposure to physiological
conditions will shift to the gel (semi-solid) phase, thus increasing the precorneal residence
time and enhancing the ocular bioavailability of the drug.

Mechanism by which Insitu gels are being formed in eye are,
Temperature Dependent System
pH dependent system

4.1.2 Ophthalmic Cationic emulsion

They are developed by the Novagali
pharmaceuticals for ophthalmic
applications in retina via the trans-scleral
route

Electrostatic attraction that occurs between
positively charge droplets and negatively
charged cell membranes.

Administration onto the eye has shown,
increase the residence time of the drug at
cornea, with a lower contact angle and an
increased spreading coefficient in
comparison with conventional eye drops
and anionic emulsions.
8 / 45
4.1.3 Ophthalmic Iontophoresis

Iontophoresis is an active method of
drug delivery which uses a small
electrical current to transport ionized
drugs into and through body tissues.

The results of studies in rabbit,
demonstrate that iontophoresis offers
a noninvasive and reproducible means
of delivering a model anionic drug to
eye tissues, specifically to the retina.

These studies serve as the basis for
future clinical studies aimed at
delivering therapeutic drugs to the
back of the eye for treatment of ocular
diseases, such as Age-related macular
degeneration (AMD) and diabetic
retinopathy (DR).

4.1.5 Ophthalmic Discosomes

Disc shaped niosomes are known as discosomes.

Discosomes, in addition to their many advantages, seem to have a special
advantage towards the ocular route, wherein their large size may prevent
their drainage into the systemic pool.

Furthermore, their ‘‘disc’’ shape provides for a better fit in the cul-de-sac
of the eye.

Non-ionic surfactant-based discoidal noisome (discosomes) of timolol
maleate have been reported to be promising systems for the controlled
ocular administration of water-soluble drugs, releasing the drug in a
biphasic profile.
11 / 45
4.1.6 Ocular Inserts

A truly continuous Zero order kinetic &
controlled release was achieved using
ocusert.

Pilocarpine ocuserts ( by Alza corporation
of California) i.e. pilo- 20 & pilo- 40 are
examples

This device is more popular among
younger patients as compared to elder
population who have difficulties in
insertion, do not retain device well and
often do not notice if it falls out.

The major drawback for using this therapy
is
1.
high cost of the device
this system is not biodegradable,
required to be removed and replaced with a fresh one.
2.
3.

They also include soluble, bioadhesive
ophthalmic inserts, prosert and
mydriasert.

4.2.1 Liposome and Lipid Based Formulation





Promising in sustaining the drug residence time within lung, improving
therapeutic index, and delaying systemic dilution and thereby, reducing
side effects and to control the extent of release.
Delivery of corticosteroid for asthma, ribonucleotides for respiratory
influenza aminoglycosides (Tobramycin Sulphate, Amikacin Sulphate)
and other antibiotics (Ciprofloxacin) for local pulmonary infections and
cystic fibrosis has been reported using liposome technology.
In liposomal DPI formulations, drug encapsulated liposomes are
homogenized, dispersed into carrier and converted into DPI by spray and /
or freeze drying.
On inhalation, drug encapsulated liposome’s get rehydrated in lung and
release drug over a period of time.
Fatty acid esters were incorporated in the lipid portion of liposome’s for
prolonged steroid retention in the respiratory tract.
15 / 45
4.2.2 Proliposomes

Biologically active component with a lipid or mixture having a
phase transition temperature of below 37°C for inhalation has
been described for manufacturing of proliposomes.

A DPI formulation comprising a lipid component and an active
agent having a liquid phase transition temperature of less than
or equal to 37°C on hydration and a liquid phase transition
temperature of greater than 57°C in dry form.

On inhalation the drug spontaneously encapsulates into lipid
inside lungs. The disclosed formulation is useful in treatment
of anthrax infection on inhalation.
16 / 45
4.2.3 Nanocochleates

Cochleates are derived from liposomes.

These are suspended in an aqueous containing two-phase
polymer solution, perceiving different partition coefficient.

The liposome containing two-phase polymer solution, treated
with positively charged molecules such as Ca2+ or Zn2+,
forms a cochleate precipitate of a particle size less than 1 µm.

Novel lipid-based cochleate delivery system were used to
achieve efficient systemic and mucosal delivery of
pharmaceutical agents.
17 / 45
4.2.4 Micro and Nanoparticulates DPI Compositions




Respirable particles carrying active principles or diagnostics in
nanoparticle
Nanoparticulates DPI produced by mixing the nanoparticles
with liquid carrier, then forming the resultant mixture into
respirable particles.
The respirable particles were produced by spray-drying or
freeze spray drying followed by comminution, for delivery to
the lungs via DPIs.
Active principles were covalently attached, adsorbed or
incorporated to nanoparticles.
18 / 45
4.2.5 Delivery of Proteins, Peptides and Macromolecules for
Local and Systemic Delivery Using DPIs





It has been found that inhaled dry insulin powders are deposited in the
alveolar regions of the lungs and rapidly absorbed through the epithelial
cells of the alveolar region into blood circulation.
The insulin powder preferably comprises particles having a diameter range
from 0.1 µm to 5 µm.
A patent on pulmonary malarial vaccine relates to particulate compositions
comprising nanoparticulates for pulmonary delivery, which provide
sustained release of antigens, preferably DNA and/or peptide and/or protein
antigens has been developed.
As the aggregate particles degrade in the body, MSP-1 and AMA-1
proteins are released into the blood stimulating a humoural immune
response.
The individual particles in the range of 0.1 micron are referentially
phagocytosed & initiating the cellular immune response that is necessary
for a complete immunity.

Gliadel Wafer (polifeprosan 20 with carmustine implant) is indicated in
newly diagnosed patients with high-grade malignant as an adjunct to
surgery and radiation.

After a neurosurgeon removes a high-grade malignant, up to eight Gliadel
Wafers can be implanted in the cavity where the tumor resided.

Once implanted, the Gliadel Wafers slowly dissolve, releasing high
concentrations of BCNU into the tumor site targeting microscopic tumor

DepoMorphine™), our DepoFoam™ sustainedrelease injectable technology maintains
therapeutically effective levels of morphine for
48 hours (the period of peak post-operative pain)

4.4.6 Others

Transferosomes: Modified liposomes developed to increase the transdermal permeation of drug.
Deformability is achieved by using surface active agent in proper ratio.

Ethosome: Ethosomal system is a vesicular system composed mainly of phospholipids & alcohol (ethanol
or IPA, sometimes polyols; glycol) in relatively high concentration & water. Better membrane permeability.

Discosomes

Virosomes: Reconstituted lipid vesicles equipped with viral glycoprotein is used for DNA transfer.

Emulsomes: The emulsomes can be explicitly distinguished from fat emulsion or lipid microsphere as they
are distinctively sphere vesicular graft like system due to utilization of higher quantities of PC both as
emulsifying agent as well as surface modifier.

Cochleates: Cochleates are cigar-like microstructures that consist of a series of lipid bilayers which are
formed as a result of the condensation of small unilamellar negatively charged liposomes. In the presence
of calcium, the small phosphatidylserine (PS) liposomes fuse and form large sheets. These sheets have
hydrophobic surfaces and, in order to minimize their interactions with water, tend to roll-up into the cigarlike cochleate.
