| name | Trichloroacetic Acid (TCA) |
| Classification | Chemical irritant, used primarily as a tissue/skin escharotic, not a pharmaceutical drug in the traditional sense. |
| Pharmacokinetics | Trichloroacetic acid is not typically administered systemically. Absorption and distribution primarily depends on the route of application. It directly causes tissue damage and denaturation of proteins. Systemic absorption, while possible with certain routes, is poorly understood and usually not a primary factor in its use. |
| suggested dosage | Dosage is highly variable and depends entirely on the intended application (e.g., skin lesion removal). No standard oral, intravenous, or intramuscular dosages exist. |
| indications | TCA is primarily used in very specific dermatological applications:
* Treatment of certain skin lesions (e.g., warts, skin cancers, some benign growths) via topical application.
* Chemical cauterization in specific surgical procedures.
* Destruction of specific types of tissue. |
| Safety in pregnancy | Data are extremely limited. TCA is not intended for systemic use in pregnancy. Avoid application in any way to areas of the body where there's a possibility of fetal exposure. If a pregnant patient requires an application requiring TCA use, it would require very specific risk/benefit assessment by a physician, possibly necessitating alternate treatments or procedures. |
| Safety in breastfeeding | TCA should not be used topically on the breast or any area of the body that could result in possible infant exposure. Due to the unknown systemic effects and potential for fetal/infant harm, TCA should not be administered during breastfeeding, as it presents a high risk. |
| side effects | | 1 | Severe local tissue damage (eschar formation, necrosis) | | 2 | Pain, erythema | | 3 | Skin discoloration | | 4 | Scarring | | 5 | Possible systemic effects (if significant amounts are absorbed) - though generally, this is a local only treatment |
|
| alternative drugs | | 1 | | alternative | Cryotherapy | | description | Use of extreme cold to destroy abnormal tissues. May be applicable to certain conditions. |
| | 2 | | alternative | Surgical excision | | description | Surgical removal of the affected area. May be better suited to larger or deeper lesions. |
| | 3 | | alternative | Laser therapy | | description | Use of focused laser energy to eliminate abnormal tissue. Can be effective in certain cases. |
|
|
| contraindications | | 1 | Known hypersensitivity to TCA | | 2 | Open wounds, infections, or inflamed areas where application is not indicated. | | 3 | Use in pregnant or breastfeeding women (unsuitable). | | 4 | Severe underlying skin conditions where application could have adverse effects. | | 5 | Use in children without appropriate supervision and risk/benefit assessment from a physician |
|
| interactions | Information regarding interactions with other drugs is limited, as it is a chemical irritant and not a standard drug. |
| warnings and precautions | | 1 | Apply TCA only under the direct supervision of a qualified medical professional. | | 2 | Use appropriate protective equipment (gloves, eye protection). | | 3 | Closely monitor the application site for any adverse reactions. | | 4 | Strict adherence to the prescribed application method is critical. | | 5 | Never self-treat with TCA, always seek medical advice and supervision. | | 6 | Thorough risk assessment is needed in each case. |
|
| additional informations | TCA's use is limited to carefully-selected situations and under strict medical guidance. Its main purpose is localized tissue destruction, not systemic therapy. The specific patient's condition, anticipated outcome, and potential risks need to be weighed. |
