Table 1

Main advantages and drawbacks of different nonantibiotic macrolides in skin diseases.

MacrolideAdvantagesDrawbacks

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 [5153] 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.
