Hello Sanjay
Your father is 70 years old and an asthmatic patient .
When such patient visit with these symptoms I prescribe my patient MONTELEKAST+ BAMBUTEROL tablet once or twice in day depending on the condition of patient and severity of symptoms .
Usually patients responds very well and don't require any inhaler .
Now about
deriphyllin injection ( don't gibe
betnesol as this is very dangerous for prolong use and keep this drug only for acute emergency ).
So DERIPHYLLINE is available in 2 ml strength .
Take 2 ml in a syringe and introduce in vein ( INTRAVENOUS ) and insert medicine in the vein very very slow .
2nd option is intramuscular either in the deltoid ( shoulder ) or gluteal muscle (hip ) .
Avoidance for pollen , mold , pests ( cockroaches ) , hay, fodder,fine dusting powder , sudden fall and rise of temperature , humidity , mite, dust are certain predisposing factor which triggers an asthmatic attack.
Air conditioner , hot coffee , steam inhalation also helps.
Hope these information will be helpful for your father.
