My daughter is almost 2 year old, she is coughing almost every 5min...she does not want what to eat what can i get from the pharmacy to give to her...

Herbs, homeopathy: This is almost certainly a virus. Antibiotics won't help. Cough drops/cough syrup with dextromethorphan can reduce coughing but won't shorten duration. Try Pelargonium sidoides (sold as Umcka in US), a South African herb proven to help bronchitis. And try homeopathy; the right remedy can work like magic; to find the right remedy see http://www.healthy.net/Health/Article/Cough_Children_Infant/784
