Anti-Hemorrhoid Drugs are
medicines that reduce the swelling and relieve the discomfort of
hemorrhoids (swellings in the area around the anus).
Purpose
Hemorrhoids are bulges in the veins that supply blood to the skin
and membranes of the area around the anus. They may form for various
reasons. Frequent heavy lifting, sitting for long periods, or
straining to have bowel movements may put stress on anal tissues,
which can lead to hemorrhoids. Some women develop hemorrhoids during
pregnancy as the expanding uterus puts pressure on the anal tissues.
The strain of labor and delivery can also cause hemorrhoids or make
existing hemorrhoids worse. Hemorrhoids sometimes result from
certain medical problems, such as tumors pressing on the lower
bowel.
The main symptoms of hemorrhoids are bleeding from the rectum,
especially after a bowel movement, and itching, burning, pain and
general discomfort in the anal area. Over-the-counter
anti-hemorrhoid products can relieve many of these symptoms. The
products contain combinations of four main types of ingredients:
- Local Anaesthetics such as Benzocaine, Lidocaine and
Tetracaine, to temporarily relieve the pain.
- Vasoconstrictors, such as Epinephrine Base, Epinephrine
Hydrochloride, Ephedrine Sulfate and Phenylephrine Hydrochloride
that reduce swelling and relieve itching and discomfort by
tightening blood vessels.
- Astringents (drying agents), such as Witch Hazel, Calamine,
and Zinc Oxide. These help shrink hemorrhoids by pulling water
out of the swollen tissue. This, in turn, helps relieve itching,
burning, and irritation.
- Protectants, such as Cocoa Butter, Lanolin, Glycerin, Mineral
Oil, and Shark Liver Oil which soothe irritated tissues and form
a protective barrier to prevent further irritation.
Description
Anti-Hemorrhoid Drugs are available as creams, ointments and
suppositories. Most can be bought without a physician's
prescription.
