Medication for Hemorrhoids
Local anesthetics like Medicone, Benzyl Alcohol, Pramoxine and Tetracaine are required to alleviate the pain and burning sensation of the rectum. Vasoconstrictors are used to constrict the blood vessels and reduce swelling. Epinephrine, Rectaine and Phenylephrine are commonly used drugs for hemorrhoids. Protectants are drugs that form a physical barrier around the peri-anal area and prevent irritation and pain. Starch, mineral oil, cocoa butter, Kaolin and Lanolin can be used for this purpose. Astringents can also be used for the same purpose and they cause coagulation of proteins in the cells. Calamine and zinc oxide are common examples of astringents used for hemorrhoids. Antiseptics have to be used to prevent infection, and keratolytics allow the medication to penetrate into tissues.
