reduces availability of oxidised COX-2
this interferes with transmission of pain signals between spinal cord and higher centres reducing pain sensitivity
it also reduced PGE2 concentration in the thermoregulatory region of the hypothalamus reducing fever

4) acute pulmonary oedema, alongside oxygen, furosemide and nitrates
35
MOA of opiods for pain
agonism of mu receptors in the central nervous system
activation of the G protein coupled receptor has several effects that overall reduced excitability and pain transmission
36
MOA of opiods for breathlessness
in the medulla they blunt the response to hypoxia and hypercapnia, reducing respiratory drive and breathless
37
MOA of opioids for pulmonary oedema
by relieving pain, breathlessness, opioids reduce sympathetic nervous system activity.
this reduced cardiac work and oxygen demand

Thyroid gland produce thyroxine (t4 ) which is converted into a more active form called triodothyronine (t3) in target tissue.
Levothyroxine is a synthetic T4
Liothyronine is a synthetic T3
Liothyronine has a quicker onset and shorter half life than Levothyroxine hence used in emergency
