hi guys... i have been looking around for potent cough meds for my grandma, i have noticed that there's only guaifenesin salbutamol or guaifenesin codeine combo syrups out there but not guaifenesin salbutamol codeine together... anyone can help?

there might not be any since those 3 target specific areas, putting those 3 together would either be very strong for intake or might have adverse side effects. just my thoughts...

go for codeine linctus.
any opiates and opioids are potent/very potent antitussives.
the better ones have stronger concentrations of opiates (hence the use of cough medicines y drug addicts, due to high concentrations of opiates).

google codeine + cough syrup then u will get your choices
