I Have Bronchitis, No Fever, And Am Using An Inhaler

I have bronchitis, no fever, and am using an inhaler I received in January when I had bronchitis. I have a very persistent, annoying cough and want to know the best medication I can purchase for this condition so I will cough less without causing it to get worse. I regularly take Triamterene/hctz 37.5/25, Atenolol 25mg, and Citalopram 20 mg daily along with two 81mg aspirin.
