An '''antidiarrhoeal drug''' is any [[medication]] which provides symptomatic relief for [[Diarrhea|diarrhoea]].

==Types==
* [[Electrolyte]] solutions are used to replace lost fluids and [[salt]]s in acute cases.
* [[Bulking agent]]s like [[methylcellulose]], [[guar gum]] or plant [[dietary fiber|fibre]] ([[bran]], [[sterculia]], [[ispaghul]], etc.) are used for diarrhoea in functional bowel disease and to control [[ileostomy]] output.
* [[Absorbent]]s absorb toxic substances that cause infective diarrhoea, methylcellulose is an absorbent as well.
* [[Opiate]]s slow intestinal transit, but [[Loperamide]] is most commonly used, since it doesn't have the usual narcotic [[adverse drug reaction|side effect]]s.
