The are many anti-hemorrhoids drugs available in the market. The drugs that are prescribed for the treatment of hemorrhoids are usually the same as those used for treating anal symptoms like itching or discomfort. These drugs probably reduce only the symptoms of hemorrhoids. Anti hemorrhoid drugs used for the treatment of hemorrhoids are in the form of creams, gels, ointments, suppositories, foams, and pads.
There are different ways of applying these medications. For example, ointments, creams, and gels should be applied as a thin covering when used around the anus. On the other hand, when they are applied to the anal canal, they should be inserted with a finger or a "pile pipe." Prior to insertion, pile pipes should be lubricated with ointment. Suppositories or foams are easy to use and apply than ointments, creams, and gels.

They also reduce pain and itching. Vasoconstrictors can also taken orally or by injection. But when applied to the perianal area, there is lower chances of serious side effects, like high blood pressure, tremor, nervousness, sleeplessness, and diabetes or hyperthyroidism.
Protectants are used prevent irritation of the perianal area. When they are applied, they form a physical barrier on the skin. The irritated skin is prevented from contacting with aggravating liquid or stool from the rectum. This barrier reduces itching, pain, irritation, and burning.
Astringents lead to coagulation of proteins in the cells of the perianal skin or the anal canal's lining. Astringents promote skin dryness, which in turn helps relieve itching, burning, and pain.
Antiseptics prevent bacteria and other organisms's growth. However, so far it is not yet been clear whether antiseptics are any more effective than soap and water.
The anti hemorrhoid drugs in the form of chemicals that cause the outer layers of skin or other tissues to disintegrate. The two approved keratolytics used are:
Analgesic anti hemorrhoid drugs include anesthetic products, relieve pain, burning, itching by depressing receptors on pain nerves. For example:
They reduce inflammation. They also relieve itching. But when they are used for a long term, they can cause permanent damage to the skin. They should be used at the most for two weeks. Only products with weak corticosteroid effects are available over-the-counter. Stronger corticosteroid products that are available by prescription should not be used for treating hemorrhoids.
