(20 cards)
It is also called as Terminal Neurotransmitter of Sympathetic NS
Norepinephrine
It is also called as Terminal Neurotransmitter of Parasympathetic NS

Define Agonist
drugs that
produces a response
Define Antagonist
it is the drugs that
blocks a response
and its Effects are determined by
the inhibitory action of the
drug.

What does ADRENERGIC BLOCKERS do.
It is a direct blocking by occupying
receptors
and also an indirect blocking by inhibiting
release of neurotransmitters
What are those causes of ‘ALPHA
BLOCKERS’
- Relaxation of smooth muscles
- Vasodilation: hypertension and PVDs
- Reduces contraction of smooth muscle in
bladder and prostate
What are those causes of “BETA BLOCKERS”
- Decrease heart rate
- Decreases blood pressure
- Useful for treating mild to moderate

OF “Donepezil, Rivastigmine, Galantamne”
It is use for Alzheimer’s disease
to improve cognitive function
What does NICOTINE, do as “GANGLIONIC
BLOCKERS”
- Stimulate and block cholinergic function
- Increase production of neurotransmitters
- Increase BP, HR but may also decrease BP
– non-selective effect - CNS Stimulation – causes addiction
- Not useful in clinical practice
