These effects were not seen in rat or rabbit studies, and the effects on human pregnancy have not been studied.
[L52145]
The risk and benefit of use during pregnancy should be weighed as bone deformities, tracheoesophageal fistula, anal atresia, low birthweight, and withdrawl have been reported in the children of mothers who were taking dextroamphetamine during pregnancy.
[L52145]
Mothers should not take amphetamines while nursing as the drug is excreted in breast milk.
[L52145]
Long term effects of dextroamphetamine have not bee determined in pediatric patients and dextroamphetamine should be avoided in children under 3 years.

Proteins and enzymes this drug interacts with in the body
PMID:23363473 PMID:37914936 PMID:38081299 PMID:38517752 PMID:8643547
Regulates the transvesicular monoaminergic gradient that determines the quantal size.
Mediates somatodendritic dopamine release in hippocampal neurons, likely as part of a regulated secretory pathway that integrates retrograde synaptic signals (By similarity). Acts as a primary transporter for striatal dopamine loading ensuring impulse-dependent release of dopamine at the synaptic cleft (By similarity). Responsible for histamine and serotonin storage and subsequent corelease from mast cell granules PMID:8860238
PMID:2008212 PMID:8125921 PMID:38750358
Is responsible for norepinephrine re-uptake and clearance from the synaptic cleft, thus playing a crucial role in norepinephrine inactivation and homeostasis (By similarity). Can also mediate sodium- and chloride-dependent transport of dopamine PMID:11093780 PMID:8125921 PMID:39395208 PMID:39048818

Also mediates sodium- and chloride-dependent transport of norepinephrine (also known as noradrenaline) (By similarity). Regulator of light-dependent retinal hyaloid vessel regression, downstream of OPN5 signaling (By similarity)

Also functions as a receptor for various drugs and psychoactive substances, such as amphetamine and methamphetamine .
PMID:31399635 PMID:37935376 PMID:37935377
Unresponsive to classical biogenic amines, such as epinephrine and histamine and only partially activated by dopamine and serotonin .
PMID:11459929 PMID:11723224
Expressed in both the central and peripheral nervous system: TAAR1 activation regulates the activity of several neurotransmitter signaling pathways by (1) decreasing the basal firing rates of the neurons involved and by (2) lowering the sensitivity of receptors to neurotransmitters .
PMID:37935376 PMID:37935377 PMID:37963465 PMID:38168118
Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of downstream effectors .
PMID:31399635 PMID:37935376 PMID:37963465
TAAR1 is coupled with different G(i)/G(o)-, G(s)- or G(q)/G(11) classes of G alpha proteins depending on the ligand .
PMID:31399635 PMID:37935376 PMID:37963465
CAD-binding is coupled to G(i)/G(o) G alpha proteins and mediates inhibition of adenylate cyclase activity .
PMID:37935376 PMID:37963465
T1AM- or beta-PEA-binding is coupled to G(s) G alpha proteins and mediates activation of adenylate cyclase activity .
PMID:37935376 PMID:37963465
CHA- or IAA-binding is coupled to G(q)/G(11) G alpha proteins and activates phospholipase C-beta, releasing diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) second messengers .
PMID:37935376 PMID:37963465
TMA-binding is coupled with all three G(i)/G(o)-, G(s)- or G(q)/G(11) G alpha protein subtypes .
PMID:37935376 PMID:37963465
Amphetamine-binding is coupled with G(s)- or G(12)/G(13) G alpha protein subtypes PMID:31399635
