Naphazoline is a medicine used as a decongestant, and a vasoconstrictor added to eye drops to relieve red eye. It has a rapid action in reducing swelling when applied to mucous membrane. It is a sympathomimetic agent with marked alpha adrenergic activity that acts on alpha-receptors in the arterioles of the conjunctiva to produce constriction, resulting in decreased congestion.
We’re going to about learn about the new drug that is the nephazoline naphazoline belongs to the class of the sympathomimetic drug okay what do you mean by sympathomimetic drug the drugs which mimics means do the mimicry of the action of the stimulation of the sympathetic nerves okay what will they will do they will mimac means they will do the mimicry means they
Will copy the action which happens on the stimulation of the sympathetic neurons okay so let’s know more about the naphazoline it is indicated in the well ocular vasoconstriction in ocular vasoconstriction it is indicated like in the cases of the conjunctivitis okay and also in the nasal condition where there is the high nasal congestion or the rhinitis at that
Time naphazoline is indicated now we’ll see the more of action of the naphazoline naphazoline is the symbol mimetic alpha adrenergic agonist it means that it increases the activity of the alpha adrenergic receptor okay like what will happen it stimulate the alpha adrenergic receptors in the arterioles of the conductivity means the eye condition okay which causes
The vasoconstriction okay what what happens in the conjunctivitis your eye will become very much red okay so what it does it constrict the all the way vessels which are present in the eye okay of the conjunctival blood vessels thereby decreasing the conjunctival congestion okay so by doing the vasoconstriction what it does it reduces the conjunctival infection
Of the eye and in also in the nasal congestion also the similar mechanism has been done that constriction of the vases has been done so the blood supply to the nose will be decrease and so that it will causes it will relieve the all the condition of the nasal okay so this is all about the mode of action it is the simple mode of action it has it that it stimulates
The alpha adrenergic receptors okay which causes the vasoconstriction and this funda is being indicated in the treatment of the conjunctivitis okay and also in the nasal condition now we’ll see what are the brand names which are available brand names which are famously available are the i code these are the eye drops of custards sorry ocu rest these are also
Eye drop and the icon so this is all available most profoundly it has been used in the cases of the conjunctivitis okay because of its sympathy mimetic activity as it caused the vasoconstriction so it is most profoundly used in the conjunctivitis okay so this is all about the nafa zoli okay thank you for watching you
