Bisacodyl is typically prescribed for relief of constipation and for the management of neurogenic bowel dysfunction as well as part of bowel preparation before medical examinations, such as for a colonoscopy. Some drugs (e.g., diuretics, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, or non-steroidal anti-inflammatory drugs) increase risk due to fluid and electrolyte changes. Most common adverse reactions (> 3%) are overall discomfort, abdominal fullness, abdominal cramping, nausea, and vomiting.

Protoveratrine B is one of two alkaloids isolated from the plant Veratrum albumen. The main effect of both alkaloids is vasodilation in all vascular beds thereby reducing blood pressure. In the 1950's it was recognized that Protoveratrine B is the preferred compound which can be administered at significantly higher doses before the patient begins to vomit.

Protoveratrine A, the principal alkaloid of Veratrum album, has been used in the treatment of hypertension but has largely been replaced by drugs with fewer adverse effects.

Dienestrol (INN, USAN) (brand names Ortho Dienestrol, Dienoestrol, Dienoestrol Ortho, Sexadien, Denestrolin, Dienol, Dinovex, Follormon, Oestrodiene, Synestrol, numerous others) is a synthetic, non-steroidal estrogen. It is an estrogen receptor agonist. Estrogens work partly by increasing a normal clear discharge from the vagina and making the vulva and urethra healthy. Using or applying an estrogen relieves or lessens: dryness and soreness in the vagina, itching, redness, or soreness of the vulva. Conditions that are treated with vaginal estrogens include a genital skin condition (vulvar atrophy), inflammation of the vagina (atrophic vaginitis), and inflammation of the urethra (atrophic urethritis). Dienestrol currently discontinued in US, but still in market in some other counties
