WARRINGTON, Pa., Oct. 4, 2013

WARRINGTON, Pa., Oct. 4, 2013 /PRNewswire/ --Discovery Laboratories, Inc.
(NASDAQ: DSCO), a specialty biotechnology company dedicated to advancing a new
standard in respiratory critical care, today announced the U.S. Food and Drug
Administration (FDA) has agreed to the Company's updated product
specifications for SURFAXIN^® (lucinactant) Intratracheal Suspension which was
approved for the prevention of respiratory distress syndrome (RDS) in
premature infants at high risk for RDS. The Company has initiated
manufacturing of SURFAXIN for its planned commercial introduction in the
fourth quarter of 2013. SURFAXIN is the first FDA-approved synthetic,
peptide-containing surfactant available for the prevention of RDS in premature
infants and the only approved alternative to animal-derived surfactants
currently used today.

"We are pleased that the FDA has agreed with our updated product
specifications and are appreciative of the process that has lead to this
decision," said John G. Cooper, Chief Executive Officer of Discovery Labs.
"SURFAXIN represents the first milestone in our goal of transforming the
treatment ofRDS and is an important medical advancement for the neonatology
community and parents of preterm infants who will soon have an effective
alternative to animal-derived surfactants for the prevention of RDS."

ABOUT SURFAXIN
The U.S. Food and Drug Administration (FDA) approved SURFAXIN^® (lucinactant)
Intratracheal Suspension for the prevention of RDS in premature infants who
are at high risk for RDS. SURFAXIN is the first synthetic, peptide-containing
surfactant approved by the FDA and the only alternative to animal derived
surfactants.

IMPORTANT SAFETY INFORMATION
SURFAXIN is intended for intratracheal use only. The administration of
exogenous surfactants, including SURFAXIN, can rapidly affect oxygenation and
lung compliance. SURFAXIN should be administered only by clinicians trained
and experienced with intubation, ventilator management, and general care of
premature infants in a highly supervised clinical setting. Infants receiving
SURFAXIN should receive frequent clinical assessments so that oxygen and
ventilatory support can be modified to respond to changes in respiratory
status.

Most common adverse reactions associated with the use of SURFAXIN are
endotracheal tube reflux, pallor, endotracheal tube obstruction, and need for
dose interruption. During SURFAXIN administration, if bradycardia, oxygen
desaturation, endotracheal tube reflux, or airway obstruction occurs,
administration should be interrupted and the infant's clinical condition
assessed and stabilized.

SURFAXIN is not indicated for use in acute respiratory distress syndrome
(ARDS).
