Photosensitive substances

What are some examples of photosensitive substances? - Quor

  1. Besides chemicals others already named, there area also natural substances that are photosensitive (like leaves of shrubs that are green unless getting more/to much sunlight then they turn red. But there also plant-based materials if you take them / eat them, you as a person turn photosensitive (sun-sensitive)
  2. Many medications and supplements contain ingredients that may cause photosensitivity, which is defined as a chemically induced change in the skin that makes an individual unusually sensitive to light
  3. Drug- and chemical-induced photosensitivity occurs when a drug or chemical agent combines with UV radiation to cause a phototoxic or photoallergic reaction. These agents are called photosensitisers and can be topical agents or medications that are taken orally
  4. Sun-sensitive or photosensitive drugs are drugs that cause a moderate to severe skin reaction that is similar to a bad sunburn when exposed to the sun (UV rays), usually the forehead, nose, hands, arms, and lips. Many common medications cause this reaction in some people. Usually, the allergic reaction appears within 24 hours of sun exposure and resolves when the blisters from the rash peel.

In hepatogenous photosensitization, the photosensitzing substance is phylloerythrin, a normal end-product of chlorophyll metabolism. It accumulates in the body because of liver damage, reacts with UV light on the skin, and leads to free radical formation. These free radicals damage the skin, leading to ulceration, necrosis, and sloughing Fluoroquinolones and tetracyclines are two such drugs that produce photo-toxic effects. Surface contact with these chemicals can also cause photo-dermatitis or photo-allergy, also referred to as sun poisoning

Among the most common phototoxic drugs are amiodarone (Cordarone, a heart medication). NSAIDs (nonsteroidal anti-inflammatory drugs such as ibuprofen), and the tetracycline family. It's important.. Photosensitized reactions may also lead to the degradation of the drug substances [ 6 ]. The photoproducts of a drug may be harmful and cause phototoxic, photoallergic, or photosensitization reactions upon administration [ 7 - 9 ] Photosensitivity may be referred to as photoallergy or sunlight allergy, even though an actual allergy is not associated with the condition. Four-hundred drugs are known to cause lightsensitive and photo-allergic reactions Medications that are known to cause photosensitivity in some people include tetracyclines (a class of antibiotics often used to treat infections in the urinary tract, respiratory tract and the intestines) and nonsteroidal anti-inflammatory drugs (also known as NSAIDS) like aspirin and ibuprofen Sun Allergy (Photosensitivity) Medically reviewed by Drugs.com. Last updated on May 13, 2021. Health Guide; What is a Sun Allergy (Photosensitivity)? A sun allergy is an immune system reaction to sunlight, most often, an itchy red rash.

It can be triggered by products applied to the skin or medicines. The definition of suitable photoprotective systems is fundamental for pharmaceutical manufacturing and for human healthy as well, since light exposure may affect either drugs or drug formulations giving rise even to allergenic or mutagenic by-products

Degradation of Drugs in light Many drugs are prone to degrade in Presence of light. So, the impact of light on physical and chemical attributes of drug substance must be identified in order to prevent its degradation. International conference on harmonization Q1b provides guidelines for photostability testing of new drug substances. In presence of light some Active pharmaceutical ingredients. Photosensitivity can be described as an allergic reaction of the body (or skin) on exposure to the sun. Phototoxic Drug (or Chemical) Induced Photosensitivity occurs when there is a reaction between drugs (or chemicals) and ultraviolet (UV) light Photosensitivity reactions include solar urticaria, chemical photosensitization, and polymorphous light eruption and are usually characterized by an itchy eruption on patches of sun-exposed skin. People may inherit a tendency to develop these reactions Photosensitivity dermatitis is the name given to an eczematous eruption arising in response to exposure to electromagnetic radiation. It is most commonly provoked by exposure to sunlight. The reaction may relate to UVB, UVA and/or visible light. It arises in all skin types. Photosensitivity dermatitis has several causes Photosensitivity is an abnormal skin reaction to direct sunlight exposure. It is unrelated to a sunburn. These reactions are due to photosensitization, the accumulation of photosensitive compounds beneath the skin. In some cases, the photodynamic substances come from ingested plants or drugs, after being metabolized or not
