Tretinoin, also known as 'all-trans retinoic acid (ATRA'), is a medication used for the treatment of acne and acute promyelocytic leukemia. For acne, it is applied to the skin as a cream, gel or ointment. For acute promyelocytic leukemia, it is effective only when the RARA-PML fusion mutation is present and is taken by mouth for up to three months. Topical tretinoin is also the most extensively investigated retinoid therapy for photoaging.

Minocycline, sold under the brand name Minocin among others, is a tetracycline antibiotic medication used to treat a number of bacterial infections such as some occurring in certain forms of pneumonia. It is generally (but not always) less preferred than the tetracycline doxycycline. Minocycline is also used for the treatment of acne and rheumatoid arthritis.

thumb|Pure Sulfacetamide sodium salt is a white or slightly yellow crystalline powder Sulfacetamide is a sulfonamide antibiotic commonly used in the treatment of bacterial infections, particularly those affecting the eyes and skin. It functions by inhibiting the synthesis of folic acid in bacteria, which is essential for their growth and reproduction, thereby exerting a bacteriostatic effect. Available in various forms, including eye drops, topical solutions, and creams, sulfacetamide is often prescribed for conditions such as conjunctivitis, seborrheic dermatitis, and acne vulgaris. Its effic

Bicalutamide, sold under the brand name Casodex among others, is an antiandrogen medication that is primarily used to treat prostate cancer. It is typically used together with a gonadotropin-releasing hormone (GnRH) analogue or surgical removal of the testicles to treat metastatic prostate cancer (mPC). To a lesser extent, it is used at high doses for locally advanced prostate cancer (LAPC) as a monotherapy without castration. Bicalutamide was also previously used as monotherapy to treat localized prostate cancer (LPC), but authorization for this use was withdrawn following unfavorable trial f

Antiandrogens, also known as androgen antagonists or testosterone blockers, are a class of drugs that prevent androgens like testosterone and dihydrotestosterone (DHT) from mediating their biological effects in the body. They act by blocking the androgen receptor (AR) and/or inhibiting or suppressing androgen production. They can be thought of as the functional opposites of AR agonists, for instance androgens and anabolic steroids (AAS) like testosterone, DHT, and nandrolone and selective androgen receptor modulators (SARMs) like enobosarm. Antiandrogens are one of three types of sex hormone a

Flutamide, sold under the brand name Eulexin among others, is a nonsteroidal antiandrogen (NSAA) which is used primarily to treat prostate cancer. It is also used in the treatment of androgen-dependent conditions like acne, excessive hair growth, and high androgen levels in women. It is taken by mouth, usually three times per day.

Lymecycline is a tetracycline broad-spectrum antibiotic. It is approximately 5,000 times more soluble than tetracycline base and is unique amongst tetracyclines in that it is absorbed by an active transport process across the intestinal wall, making use of the same fast and efficient mechanism by which carbohydrates are absorbed.
