PARA-AMINOBENZOIC ACID

PARA-AMINOBENZOIC ACID: Drug: Para-aminobenzoic acid (PABA)

Use: Para-aminobenzoic acid is a nutritional supplement that is used for various purposes. One of its primary uses is as a sunscreen ingredient, as it helps to protect the skin from ultraviolet (UV) radiation. PABA is also used in the treatment of certain medical conditions such as vitiligo (a skin pigmentation disorder) and folate deficiency. Additionally, PABA is thought to have potential antibacterial and antioxidant properties, although more research is needed to fully understand its effects.

Mechanism of action: PABA functions as a coenzyme precursor necessary for the production of folic acid, which is essential for the synthesis of DNA, RNA, and amino acids. In sunscreen products, PABA acts as a UV filter, absorbing UV radiation and preventing damage to the skin.

Dose: The recommended dosage of PABA varies depending on the specific use and should be determined by a healthcare professional. For sunscreen products containing PABA, the concentration typically ranges from 3% to 15%. For medical conditions like vitiligo, doses of PABA can range from 2 to 4 grams per day, divided into multiple doses. Always follow the instructions provided by your doctor or the product label.

Side effects: PABA is generally considered safe when used as directed. However, some people may experience side effects such as itchiness, rash, or skin irritation when applying sunscreen products containing PABA. In rare cases, individuals may have an allergic reaction to PABA, which can cause more severe symptoms such as swelling, difficulty breathing, or hives. If any unusual or severe side effects occur, it is recommended to discontinue use and seek medical attention immediately.
