|
Pimecrolimus | (i) Plays an important role in the anti-inflammatory activities. (ii) Applied for the treatment of atopic dermatitis (AD) [4, 9, 10]. (iii) Inhibits the synthesis of inflammatory cytokines in psoriasis [13, 14]. (iv) Produces a dose-dependent reduction in the severity of psoriasis [15]. (v) Significantly reduces the symptoms in oral lichen planus (OLP) [16, 17]. (vi) Applied for the treatment of rosacea [23]. (vii) Shows positive clinical results in pyoderma gangrenosum (PG) [27]. (viii) Acts more selectively on T cells and mast cells in lupus dermatosis and thus has a lower possibility of systemic immunosuppression [28, 29]. (ix) Is safe and efficient for the treatment of Behçet’s disease genital ulcers, by accelerating the healing process [31]. | (i) Tacrolimus is used more often for vitiligo [19, 20, 46]. (ii) Failure in treatment of chronic autoimmune urticaria [22]. (iii) Topical 1% is not a therapeutic option in alopecia areata (AA), especially for patients unresponsive to other treatments [24]. (iv) In PG, the pharmacologic activity is more selective than tacrolimus, and the rate of cutaneous permeation is 9 times lower than that of tacrolimus and, therefore, has a lower risk of systemic immune suppression [27]. |

Tacrolimus | (i) Oral formulation offers an additional therapeutic option for management of severe and extensive AD [36]. (ii) Topical formulation is a highly effective treatment for psoriasis of the face and flexures [39] and is proposed as an alternative treatment for inflammatory skin diseases in thin skin areas, as well as, pruritus ani [42]. In addition, it is effective in PG [51–53] and in cutaneous T cell lymphomas [60]. (iii) Topical formulation (0.1%) has been used for the management of OLP and may be effective and well tolerated in the treatment of anogenital lichen sclerosus [41]. (iv) Treatment of contact dermatitis is often palliative and directed against the cutaneous inflammation itself. (v) It has been shown to reduce the incidence of lupus dermatosis in the autoimmune-prone MRL/Mp-lpr/lpr (MRL/lpr) mouse. (vi) Better results in AA treatment are achieved in combination with intralesional steroids [50]. (vii) It can be considered both effective and safe for treating skin dermatosis in systemic lupus erythematosus (LE) patients [56]. | (i) For severe active LE, its efficacy is considered limited at current dose settings and usage [55, 56]. (ii) There are contradictory results of tacrolimus as an inducer of skin cancer. |
|
Sirolimus (rapamycin) | (i) A clinical trial has shown that macrolides, in a suitable formulation, can penetrate the human skin and exert beneficial effects for the treatment of psoriasis [75, 85]. | (i) Contact sensitization to rapamycin could be developed [85]. |
|
Everolimus | (i) Potent immunosuppressive effects, antiproliferative properties, and anticancer effects have been observed. (ii) Effective in psoriasis treatment [87]. | (i) It was ineffective in combination with prednisone or cyclosporine A in 2 patients with severe AD [88]. |
|
Temsirolimus | (i) Potent immunosuppressive effects, antiproliferative properties, and anticancer effects. | (i) Applications for different types of dermatitis are not yet known. |
|
CSY0073 | (i) Anti-inflammatory and immunomodulatory effects have been observed [93]. | (i) Applications for different types of dermatitis are not yet known. |
|
EM900 EM911 | (i) Anti-inflammatory and immunomodulatory characteristics observed. | (i) Applications for different types of dermatitis are not yet known. |
|
Ridaforolimus | (i) One of the first possible applications as an antitumor agent. | (i) Applications for different types of dermatitis are not yet known. |
