Anti-Acne Treatments

Anti-acne drugs are medicines that help clear up pimples, blackheads, whiteheads, and more severe forms of acne.
Benzoyl peroxide is found in many over-the-counter acne products that are applied to the skin, such as Benoxyl, Clear By Design, Neutrogena Acne, PanOxyl, and some formulations of Clean & Clear, Clearasil, and Oxy. Some benzoyl peroxide products are available without a physician’s prescription; others require a prescription. Tretinoin (Retin-A) is available only with a physician’s prescription and comes in liquid, cream, and gel forms, which are applied to the skin. Isotretinoin (Accutane), which is taken by mouth in capsule form, is available only with a physician’s prescription. Only physicians who have experience in diagnosing and treating severe acne, such as dermatologists, should prescribe isotretinoin.
Acne is a skin disorder that leads to an outbreak of lesions called pimples or “zits.” The most common form of the disease in adolescents is called acne vulgaris. Antiacne drugs are the medicines that help clear up the pimples, blackheads, whiteheads, and more severe forms of lesions that occur when a teen has acne.
Different types of antiacne drugs are used for different treatment purposes, depending on the severity of the condition. For example, lotions, soaps, gels, and creams containing substances called benzoyl peroxide or tretinoin may be used to clear up mild to moderately severe acne. Isotretinoin (Accutane) is an oral drug that is prescribed only for very severe, disfiguring acne.
Acne is caused by the overproduction of sebum during puberty when high levels of the male hormone androgen cause excess sebum to form. Sebum is an oily substance that forms in glands just under the surface of the skin called sebaceous glands. Sebum normally flows out hair follicles onto the skin to act as a natural skin moisturizer. The glands are connected to hair follicles that allow the sebum, or oil, to empty onto the skin through a pore.
Sometimes the sebum combines with dead, sticky skin cells and bacteria called Propionibacterium acnes (P. acnes) that normally live on the skin. The mixture of oil and cells allows the bacteria to grow in the follicles. When this happens, a hard plug called a comedo can form. A comedo is an enlarged hair follicle. It can appear on the skin as a blackhead, which is a comedo that reaches the skin’s surface and looks black, or as a whitehead, which is a comedo that is sealed by keratin, the fibrous protein produced by the skin cells and looks like a white bump.
In addition, pimples can form on the skin. Types of pimples include:
• papules, which are small, red bumps that may be tender to touch
• pustules, which are pus-filled lesions that are often red at the base
• nodules, which are large, painful lesions deep in the skin
• cysts, which are painful pus-filled lesions deep in the skin that can cause scarring
Pimples form when the follicle is invaded by the P. acnes bacteria. The damaged follicle weakens and bursts open, releasing sebum, bacteria, skin cells, and white blood cells into surrounding tissues. Scarring happens when new skin cells are created to replace the damaged cells. The most severe type of acne includes both nodules and cysts.
Acne cannot be cured, but antiacne drugs can help clear the skin and reduce the chance of scarring. The goal of treating moderate acne is to decrease inflammation and prevent new comedones from forming. Benzoyl peroxide and tretinoin work by mildly irritating the skin. This encourages skin cells to slough off, which helps open blocked pores. Benzoyl peroxide also kills bacteria, which helps prevent whiteheads and blackheads from turning into pimples. Isotretinoin shrinks the glands that produce sebum. It is used for severe acne lesions and must be carefully monitored because of its side effects. Antibiotics also may be prescribed to kill bacteria and reduce inflammation.

Topical and Oral Treatments for Acne

TREATMENT
Acne treatment consists of reducing sebum production, removing dead skin cells, and killing bacteria. Treatment methods differ depending on how serious the acne is.
Topical Drugs
Topical drugs are applied directly to the affected areas of the skin. They are available in the form of creams, gels, lotions, or pads. They are used primarily to treat mild forms of acne in which there is little or no inflammation.
One group of topical drugs used for acne includes antibiotics. These drugs kill the bacteria that contribute to the disease. Another group of drugs is called comedolytics (pronounced KO-mee-do-LIE-tiks). These drugs loosen hard plugs and open pores. Still another group of drugs works by increasing the rate at which new skin cells form. These drugs prevent the formation of new comedos.
Topical drugs are applied once or twice a day after washing with mild soap. Treatment may have to continue anywhere from a few weeks to a few months to a few years. Side effects such as mild redness, peeling, irritation, dryness, and an increased sensitivity to sunlight may occur.
Oral Drugs
Oral drugs are taken by mouth. Doctors sometimes prescribe oral antibiotics for moderate cases of acne. These antibiotics prevent the formation of new comedos and reduce inflammation. They are usually taken once a day
for two to four months. Side effects may include allergic reactions, stomach upset, vaginal yeast infections, dizziness, and tooth discoloration.
A drug that is used for severe cases of acne is isotretinoin (pronounced i-so-TRET-uh-no-un, trade name Accutane). This drug reduces the production of sebum and the stickiness of skin cells. It is used when cysts and nodules are present. The drug may be used alone or with other topical or oral antibiotics.
Isotretinoin treatment usually lasts for four or five months. It is effective in about 60 percent of all patients. If the acne reappears, another course of treatments may be necessary. Some side effects that may accompany the use of isotretinoin include nosebleeds, dry skin, a temporary worsening of the acne, vision disorders, and increased production of liver enzymes, blood fats, and cholesterol. It may also cause birth defects and cannot, therefore, be used by pregnant women.
Women who do not respond to any of these treatments may be given another type of oral drug, an anti-androgen. Anti-androgens reduce the production of androgen and therefore reduce the formation of comedos. Certain types of oral contraceptives are also effective as anti-androgens.
The most serious forms of acne require other types of drugs, including oral corticosteroids, or anti-inflammatory drugs. These drugs are often used for the treatment of a form of acne known as acne fulminans, which occurs mostly among adolescent males. They are also used with acne that produces numerous deep, inflamed nodules that heal with scarring.
