The gold standard for determining potency is the vasoconstrictor assay which measures the vasoconstrictive properties based upon cutaneous vasoconstriction. The potency of topical corticosteroids is the amount of drug needed to produce a desired therapeutic effect. įoams - highly effective for steroid delivery to the scalp but are costly The immunosuppressive effects of topical corticosteroids involve the inhibition of humoral factors involved in the inflammatory response as well as suppression of the maturation, differentiation, and proliferation of all immune cells. An anti-mitotic effect is also present in the dermis which inhibits cell proliferation and collagen synthesis. The anti-mitotic effect of topical corticosteroids play a great role in the treatment of psoriasis it is proposed that this decrease in epidermal mitosis is secondary to an increase in lipocortin, an endogenous glucocorticoid-regulated protein. Topical corticosteroids also act directly at the DNA level to increase the expression of anti-inflammatory genes and indirectly inhibit inflammatory transcription factors, such as NFkb, to decrease the expression of pro-inflammatory genes. The anti-inflammatory effect also occurs from the synthesis of lipocortin which inhibits phospholipase A2, ultimately decreasing the production of prostaglandins and leukotrienes. Vasoconstriction of the blood vessels within the upper dermis decreases the number of inflammatory mediators being delivered to the region applied. The anti-inflammatory effect of topical corticosteroids consists of vasoconstriction, inhibition of the release of phospholipase A2, and a direct inhibitory effect on DNA and inflammatory transcription factors. List of Topical non-steroidal anti-inflammatoriesįor ratings, users were asked how effective they found the medicine while considering positive/adverse effects and ease of use (1 = not effective, 10 = most effective).The mechanism of action of topical corticosteroids is vast, consisting of anti-inflammatory, anti-mitotic, and immunosuppressive effects. Short-lived, mild redness at the site of application is the most commonly reported side effect. Topical NSAIDs are less likely than oral NSAIDs to cause gastrointestinal side effects or to interact with other medications, although elderly people may be more susceptible to these effects. The pain-relieving and anti-inflammatory effects of NSAIDs are mainly due to inhibition of COX-2, and their unwanted side effects are largely due to inhibition of COX-1. Most NSAIDs inhibit both enzymes, although a few are available that mainly inhibit COX-2. Prostaglandins have a number of different effects, one of which is to regulate inflammation. Both types produce prostaglandins however, the main function of COX-1 enzymes is to produce baseline levels of prostaglandins that activate platelets and protect the lining of the gastrointestinal tract, whereas COX-2 enzymes are responsible for releasing prostaglandins after infection or injury. There are two main types of COX enzymes: COX-1 and COX-2. Although different NSAIDs have different structures, they all work by blocking cyclooxygenase (COX) enzymes. NSAIDs have anti-inflammatory (reduce inflammation), analgesic (relieve pain) and antipyretic (lower temperature) effects. Topical NSAIDs may also be used in the treatment of actinic keratosis (a precancerous patch of thick, scaly or crusted skin). They are used to relieve pain and to treat symptoms of arthritis such as inflammation, swelling, and stiffness. Topical non-steroidal anti-inflammatories (often abbreviated to NSAIDs) are creams, gels, rubs, solutions or sprays that contain a nonsteroidal anti-inflammatory agent and are designed to be applied directly to the skin overlying a painful joint or area of bone. ![]()
