Statement-I: Brompheniramine (Dimetapp (or) Dimetane) is a antihistamineStatement-II:Bromopheniramine (Dimatapp (or) Dimetane) is an antacid

Dimetane is only an antihistamine but not  antacid. Seldane (terfenadine) and brompheniramine (Dimetane (or) dimetapp) interfere with the natural action of histamine by competing with histamine for binding sites of receptors where histamine exerts its effect. They are antihistamines.They are competitive inhibitors. Thus these drugs are only antihistamines but not antacids.Omeprazole, lansoprazole stop the production of acids released from any source in stomatch. They are only antacids but not antihistamine .
