Retinoic acid review

Retinoic Acid is a first-generation retinoid that Ligand gained FDA approval of in February 1999 and is also known as Panretin or Toctino. It is an antineoplastic agent developed by Ligand Pharmaceuticals.

Toctino is a capsule used to treat patients with chronic hand eczema. Panretin is a gel used to treat people with skin lesions and AIDS-related Kaposi's sarcoma. Retinoic Acid is chemically related to Vitamin A and is a yellowish powder with a molecular formula of C20H28O2 and a molecular weight of 300.44.

The gel version of Retinoic Acid, should be applied two times a day to cutaneous KS lesions during the initial stages of treatment. You may apply the gel liberally in order to cover the lesion with a generous coating, and then allow it to dry for three to five minutes before covering it with clothing. Avoid applying the gel on or near mucosal surfaces (nose, mouth, and eyes) of your body.

The capsule version must be taken after every meal and swallowed whole. Dosage ranges from 10 milligrams to 30 milligrams once every day for twelve weeks (three months) to twenty-four weeks (six months) depending on the severity of the eczema. Consult your doctor immediately if your body can't handle the recommended daily dose so that you can be prescribed a lower dose.

Panretin has some known side effects, which include itching, a burning sensation, and mild redness of the skin. You must also notify your doctor immediately if you experience these less common side effects: cracking or oozing skin, blistering, stinging or tingling skin, peeling, swelling, rash, and severe redness. It's rare for patients under Panretin treatment to get sunburn, but if you do get it, you must consult your physician as soon as possible.

Toctino also has some known side effects which include eye problems, eye inflammation or conjunctivitis, thyroid problems, decreased clotting or other blood cell disorders, flushing, muscle and joint pain, liver problems, dry skin, inflamed skin, and hair loss. Ask a pharmacist for eye drops if you need to continue Toctino treatment despite its eye-related side effects. Patients should wear glasses instead of contacts while undergoing Toctino therapy.

Before taking Panretin, you must report to your healthcare specialist your medical history, including occurrences of tumors like lymphoma, skin conditions, and allergies. This medication has been known to induce sunburn, so you should wear sunscreen and protective clothing while undergoing Panretin treatment. You should also keep the treated areas of your skin away from sunlamps. Consult your pharmacist for any further queries and concerns.

Avoid taking Toctino if you are currently taking tetracycline (a type of antibiotic); if you are allergic to Retinoic Acid, other ingredients of Toctino, or any other retinoids such as isotretinoin; if you have very high levels of Vitamin A in your body; if you have untreated thyroid disease; if you have high blood fats such as raised triglycerides or high cholesterol; if you have severe kidney disease; and if you have liver disease.

Expecting mothers should avoid using either version of this medication (Panretin or Toctino) during pregnancy because it may harm your unborn baby once it's absorbed into your bloodstream. It is not known whether this medication passes into breast milk, so it's not advised for breastfeeding mothers to use this medication. Notify your doctor before using this medication while pregnant or breastfeeding a newborn.
