止咳藥嘅分類
一般而言,止咳藥分為4類:
1.
鎮咳藥物 (Cough suppressants),如dextromethorphan, codeine, pholcodine)
2.
祛痰劑 (Expectorants),如guaifenesin, ammonia chloride, cocillana (草本類)
3.
化痰劑 (Mucolytics),如acetylcysteine, bromhexine, ambroxol, cyclidrol
4. 部分
抗組織胺 (Antihistamines), 如diphenhydramine, promethazine
而市面上都有好多唔同嘅複方產品,如Bena expectorant就有diphenhydramine (抗敏) + ammonium chloride (祛痰),Actifed compound linctus有codeine (鎮咳) + pseudoephedrine (通鼻塞) + triprolidine (抗敏),大家熟悉嘅馬尿 (MES)有ammonium chloride (祛痰) + ipecacuanha tincture (祛痰,但高劑量係攞嚟催吐) 等等
一般而言,如果係乾咳就用鎮咳藥物好啲,痰咳就用祛痰(加化痰)好啲,敏感痰咳就用有抗敏感成分嘅咳水好啲咁;想冇咁大藥性嘅就可以考慮Cocillana,佢係一種草本配方,至於有冇效果就見仁見智啦
