Embodiment 1

[0038] Batches P-14-004, P-14-014, P-14-015, P-14-016 and P-14-017 were prepared according to the teachings of the present invention with the following w / w % compositions:

[0039]

[0040] The formulations are prepared by mixing the ingredients in a suitable sealed container with a stirrer. The resulting mixture was stirred until dissolved.

Embodiment 2

[0041] Embodiment 2 (comparative)

[0042] Batches P-14-003, P-14-002, P-14-001 were prepared according to the disclosure of WO02 / 07683A1 with the following w / w% composition:

[0043]

[0044] preparation

[0045] The formulations are prepared by using suitable sealed containers with agitators. To this vessel was added ethanol, ethyl acetate, cetearyl alcohol, cyclopirox and water to form a homogeneous mixture. Then, hydroxypropyl chitosan was added, and the resulting mixture was stirred until dissolved.

Embodiment 3

[0047] The formulations prepared according to Example 1 (lots P-14-004, P-14-014, P-14-015, P-14-016 and P-14-017) and the formulations prepared according to Example 2 ( Batch P-14-001 and Batch P-14-003) were stored at the indicated temperature (5°C and 25°C) for at least 1 hour.

[0048] Photographs of the samples were taken before and after exposure times at various temperatures to assess the appearance of the solutions and reported at Figures 1 to 7 middle. The observations are summarized in Table 1.

[0049] Table 1:

[0050]

[0051]

[0052] It can be easily understood that the solutions prepared according to the teachings of the present invention (lots P-14-004, P-14-014 and P-14-015) are superior to those prepared according to WO02 / Solution prepared from the disclosure of 07683A1 (Lot P-14-003), as no white flocs were observed. The absence of white floe allows formulations prepared according to the teachings of the present invention to be shipped during ...

Abstract

The present invention is directed to a nail lacquer consisting essentially of ciclopirox as an antimycotic agent, hydroxypropyl chitosan as film forming agent, water and a lower alkanol as solvent. The invention is also directed to such a nail lacquer for use in treating onychomycosis.

Description

technical field [0001] The present invention relates to a nail polish consisting essentially of ciclopirox as an antifungal agent, hydroxypropyl chitosan as a film former, water and lower alkanol as a solvent. The invention also relates to the use of this nail polish for the treatment of onychomycosis. Background technique [0002] Onychomycosis is an infection of the nails which represents the most common nail disease in the world. At the beginning of the last century, this fungal infection was still considered fairly rare, but during the last decade of the last century its prevalence increased dramatically, in the United States (up to 40% of the general population) and Europe (nearly 30% of specific populations) ) to a very high proportion (Baran R, Hay R, Haneke E, Tosti A (Eds), Epidemiology. In: Onychomycosis-the current approach to diagnosis and therapy. London, Martin Dunitz, 1999: pp. 6-9). Currently, onychomycosis represents about 50% of all nail diseases. It is ...
