Stimulants contact or irritants

Stimulant laxatives increase peristalsis by irritating sensory nerve endings in the intestinal mucosa. Stimulant laxatives include those containing phenolphthalein

(Ex-Lax, Feen-A-Mint, Correctol), bisacodyl (Dulcolax), cascara sagrada, senna (Senokot), and castor oil (purgative). Bisacodyl and phenolphthalein are two of the most frequently used and abused laxatives because they can be purchased over-the-counter.

Results occur in 6 to 12 hours. Stimulant laxatives such as bisacodyl are used to empty the bowel before diagnostic tests (for example, barium enema) because they are minimally absorbed from the GI tract. Most are excreted in feces. However, a small amount of bisacodyl absorption excreted in the urine changes the color to reddish-brown. With excessive use, fluid and electrolyte imbalances can occur (especially potassium and calcium). Mild cramping and diarrhea are side effects.

Caster oil is a harsh laxative (purgative) that acts on the small bowel and produces a watery stool within 2 to 6 hours. Therefore, this shouldn't be taken at bedtime. Caster oil is used mainly for bowel preparation and seldom used to correct constipation. Caster oil should not be used in early pregnancy because it stimulates uterine contractions and spontaneous abortion can occur. Prolonged use of Caster oil can damage nerves resulting in loss of intestinal muscular tone.
