Pigmentation may be induced by a wide variety of drugs; the main ones implicated include non-steroidal anti- inflammatory drugs NSAIDs , phenytoin, antimalarials , amiodarone, antipsychotic drugs, cytotoxic drugs , tetracyclines , and heavy metals.

Hyperpigmentation is the darkening of an area of skin or nails caused by increased melanin. Hyperpigmentation can be caused by sun damage, inflammation , or other skin injuries, including those related to acne vulgaris. Many forms of hyperpigmentation are caused by an excess production of melanin. Melanin is produced by melanocytes at the lower layer of the epidermis.

Skin color is determined by melanin and other chromophores and is influenced by physical factors ultraviolet radiation and other endocrine, autocrine, and paracrine factors. Hyperpigmentation may be circumscribed or diffuse. Diffuse hyperpigmentation can be multifactorial in origin; hence, a multipronged approach is needed in such cases.
