Aims and objectivesThe purpose of this study is to investigate the effectiveness and safety of oral and injectable systemic treatments, such as methotrexate, azathioprine, cyclosporine, tofacitinib, baricitinib, corticosteroids, statins, zinc, apremilast, etc., for treating vitiligo lesions.MethodDatabases including PubMed, Scopus, and Web of Science were meticulously searched for studies spanning from 2010 to August 2023, focusing on systemic oral and injectable therapies for vitiligo, using comprehensive keywords and search syntaxes tailored to each database. Key data extracted included study design, treatment efficacy, patient outcomes, patient satisfaction, and safety profiles.ResultsIn a total of 42 included studies, oral mini-pulse corticosteroid therapy (OMP) was the subject of six studies (14.2%). Minocycline was the focus of five studies (11.9%), while methotrexate, apremilast, and tofacitinib each were examined in four studies (9.5%). Antioxidants and Afamelanotide were the subjects of three studies each (7.1%). Cyclosporine, simvastatin, oral zinc, oral corticosteroids (excluding OMP) and injections, and baricitinib were each explored in two studies (4.8%). Azathioprine, mycophenolate mofetil, and Alefacept were the subjects of one study each (2.4%).ConclusionSystemic treatments for vitiligo have been successful in controlling lesions without notable side effects. OMP, Methotrexate, Azathioprine, Cyclosporine, Mycophenolate mofetil, Simvastatin, Apremilast, Minocycline, Afamelanotide, Tofacitinib, Baricitinib, Antioxidants, and oral/injectable corticosteroids are effective treatment methods. However, oral zinc and alefacept did not show effectiveness.

Afamelanotide mimics endogenous alpha melanocyte-stimulating hormone (α-MSH), a hormone typically released in response to UV-induced skin damage. Both afamelanotide and α-MSH bind to the melanocortin-1 receptor (MC1R) on melanocytes which stimulates the synthesis of eumelanin, a photoprotective compound. Eumelanin is incorporated into small vesicles called melanosomes which are then distributed to surrounding keratinocytes. Melanosomes are concentrated above the nucleus of these keratinocytes, thus protecting them from UV-induced damage.[A187202] While endogenous α-MSH requires UV-induced skin damage in order to be produced, afamelanotide increases eumelanin biosynthesis independent of UV exposure.[A187205]
Activation of MC1R signalling by afamelanotide also instigates other protective processes, including an increase in antioxidant activity, DNA repair, and secretion of immunomodulatory proteins such as interleukin-10.[A187202]
How the body processes this drug — absorption, distribution, metabolism, and elimination
[L9086]
Following administration of a single subcutaneous implant, the median Tmax was 36 hours, the mean Cmax was 3.7 ± 1.3 ng/mL, and the mean AUC0-∞ was 138.9 ± 42.6 hr.ng/mL.

It has been suggested that afamelanotide may be degraded in the same manner as α-MSH but at a much slower rate, or may instead be degraded intracellularly via endocytosis or non-specific proteases.

Mediates melanogenesis, the production of eumelanin (black/brown) and phaeomelanin (red/yellow), via regulation of cAMP signaling in melanocytes PMID:31097585
PMID:32327598 PMID:33858992
Plays a role in regulating food intake: activation by a stimulating hormone such as anorexigenic alpha-melanocyte stimulating hormone (alpha-MSH) inhibits appetite, whereas binding to a natural antagonist like Agouti-related protein/AGRP promotes appetite. G-protein-coupled receptor that activates conventional Galphas signaling leading to induction of anorexogenic signaling in the hypothalamus to result in negative energy balance .
PMID:33858992
Regulates the firing activity of neurons from the hypothalamus by alpha-MSH and AGRP independently of Galphas signaling by ligand-induced coupling of closure of inwardly rectifying potassium channel KCNJ13 (By similarity). In intestinal epithelial cells, plays a role in the inhibition of hepatic glucose production via nesfatin-1/NUCB2 leading to increased cyclic adenosine monophosphate (cAMP) levels and glucagon-like peptide 1 (GLP-1) secretion in the intestinal epithelium PMID:39562740
