Summary
Ellagic acid (EA) shows promise for skin health, offering antioxidant and anti-inflammatory benefits. New formulations are improving its delivery to enhance treatment for various skin conditions.
Area of Science:
- Dermatology and Pharmaceutical Sciences
- Natural Products Chemistry
Background:
- Environmental and psychological stressors compromise skin structure and function.
- These stressors contribute to premature aging, barrier dysfunction, and various skin pathologies like acne, eczema, hyperpigmentation, and melanoma.
- Ellagic acid (EA), a polyphenol, possesses antioxidant, anti-inflammatory, and depigmenting properties beneficial for skin conditions.
Purpose of the Study:
- To review innovative formulations of ellagic acid (EA) designed to overcome its limitations.
- To enhance the therapeutic efficacy of EA for treating diverse skin diseases.
- To explore advanced delivery systems for improved skin penetration and stability.
Main Methods:
- Review of scientific literature on ellagic acid (EA) formulations.
- Analysis of nano-delivery systems including vesicles, lipidic and polymeric nanoparticles, nanospheres, cyclodextrins, and nanogels.
- Evaluation of conventional and novel preparations like ointments, creams, films, biscuits, sponges, and nanosheets.
Main Results:
- Ellagic acid (EA) demonstrates significant antioxidant, anti-inflammatory, and tyrosinase-inhibiting properties.
- EA protects against photoaging, oxidative stress, wrinkles, and loss of elasticity by strengthening collagen and elastin.
- Formulation strategies, particularly nano-delivery systems, are crucial for overcoming EA's poor solubility, instability, and skin permeability.
Conclusions:
- Innovative formulations, especially nano-delivery systems, are essential for maximizing ellagic acid's (EA) therapeutic potential in dermatology.
- Overcoming EA's physicochemical limitations can lead to more effective treatments for aging, hyperpigmentation, and other skin disorders.
- Further research into optimized EA delivery systems holds promise for advancing skincare treatments.

01:29Drugs for Treatment of Ulcerative Colitis in IBD
424
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

445
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

01:19Antiasthma Drugs: Leukotriene Modifiers
1.7K
Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:
