Description

Technical Field

[0001] This invention relates to the field of antibacterial detergents, specifically to a formulation and preparation method of a ciclopirox olamine detergent. Background Technology

[0002] Tinea manuum, tinea pedis, tinea corporis, onychomycosis, and fungal vaginitis are skin diseases caused by pathogenic bacteria, fungi, and viruses, and are highly contagious. They are more common in tropical and subtropical regions, and the incidence rate in my country is also quite high, causing great suffering to patients. Ciclopirox olamine is a broad-spectrum antifungal drug against superficial skin fungi, yeasts, and Candida albicans. At a concentration of 4-8 micrograms / ml, it can inhibit the growth of skin fungi and yeasts. It mainly works by altering the integrity of the fungal cell membrane, causing the outflow of intracellular substances and blocking the uptake of protein precursors, leading to fungal cell death. It also has some inhibitory effect on various actinomycetes, Gram-positive and Gram-negative bacteria, as well as mycoplasma, chlamydia, and trichomonas, and has strong penetrability. However, common ointments on the market have drawbacks such as difficulty in fixation, poor tackiness and peel strength, and reliance on adhesive dressings for fixation. A safer and more effective formulation that overcomes these shortcomings is needed. Ciclopirox olamine is a broad-spectrum antibacterial drug that exhibits strong inhibitory effects on fungi at low concentrations and on bacteria at high concentrations. Ciclopirox olamine lotion is a topical liquid preparation that can be applied to the skin. It is applied gently to the skin or soaked in gauze and applied directly. Ciclopirox olamine lotion has local effects such as disinfection, anti-inflammation, antipruritic, astringent, and protective properties, and has good permeability, making it particularly advantageous for treating superficial skin diseases. Existing technologies, such as patent CN201410131720.1, disclose a drug for treating scalp itching and increased dandruff, which consists of the following components by weight: ciclopirox olamine 20-50, sodium dodecyl sulfate 70-90, glycerol 5-20, sodium chloride 20-40, fragrance 0.5-2, sodium benzoate 0.1-1, citric acid as needed, and deionized water added to the appropriate amount. The invention also provides a method for preparing the shampoo, but it does not further examine the antibacterial effect and long-term stability of the drug. The accelerated test only examined the drug's condition for about 10 days, and the long-term stability is still unknown. At the same time, the invention also has the following problems: (1) The formula is too simple and lacks conditioning agents and moisturizers, which are common in shampoos, resulting in poor comfort after use; (2) The patented formula does not contain a pH buffer. The national standard for adult shampoos specifies a pH range of 4.0-9.0 (25°C), which may lead to excessive pH changes during storage; (3) Sodium benzoate is added as a preservative in the formula, while ciclopirox olamine is an antibacterial drug that already has an antibacterial effect and does not need to be added as a preservative. Sodium benzoate itself has potential harm to the human body, including damage to the nervous system and carcinogenicity.

[0003] Given the shortcomings of existing technologies, such as poor adhesiveness and peel strength, and reliance on adhesive dressings for fixation, it is crucial to find a safer and more efficient formulation that can overcome these defects. Summary of the Invention

[0122] I. Antibacterial test

[0123] The antibacterial activity of different drugs against Staphylococcus aureus was determined using the broth dilution method recommended by the National Committee for Clinical Laboratory Standards (NCCLs) M7-A6 protocol. Antibacterial assays against Candida albicans and Saccharomyces cerevisiae were performed using a modified microdilution method according to the NCCLs M-27-T protocol.

[0124] 1. Preparation of Culture Medium and Bacterial Suspension: Broth medium, Sabouraud dextrose agar medium, and RPMI-1640 liquid medium were prepared separately and sterilized for later use. Activated Staphylococcus aureus was diluted to a concentration of 10⁻⁶ with physiological saline using the McFarland turbidimetric method. 6 ~10 7 CFU·mL -1 Using the same method, the activated Candida albicans and Saccharomyces cerevisiae were diluted with physiological saline to the same concentration of bacterial suspension for later use.

[0125] 2. Preparation of Drug Stock Solutions This experiment was divided into three groups: the ciclopirox olamine lotion group, the ciclopirox olamine solution group, and the fluconazole dimethyl sulfoxide solution group (Example 1). First, stock solutions with a concentration of 12800 μg / mL were prepared. -1 The solution contained ciclopirox olamine and fluconazole dimethyl sulfoxide. Then, according to the NCCLs protocol, the antifungal stock solution prepared with dimethyl sulfoxide was diluted to a final concentration using RPMI-1640 liquid medium, and the final volume fraction of dimethyl sulfoxide should not exceed 1%. Therefore, it was diluted to 1280 μg / mL using RPMI-1640 liquid medium. -1 The solution was filtered and sterilized before use. Finally, an appropriate amount of ciclopirox olamine lotion was weighed and prepared with sterile water to a concentration of 1280 μg·mL⁻¹. -1 The solution is filtered and sterilized before use.

[0126] 3. Inoculation and Cultivation: A 96-well microplate was used. 20 μL of the prepared ciclopirox olamine lotion stock solution was added to well 1. Then, 180 μL of RPMI-1640 liquid medium was added to well 1. 100 mL of RPMI-1640 liquid medium was added to wells 2-11, and 200 μL of RPMI-1640 liquid medium was added to well 12. 100 μL of the liquid was aspirated from well 1 and added to well 2, and mixed thoroughly. 100 μL was then aspirated from well 3 and so on, until well 10. 100 μL of the liquid was aspirated from well 10 and discarded. After serial dilution, 100 μL of Candida albicans suspension was added to wells 1-11. At this point, wells 1-10 contained ciclopirox olamine at a concentration of 64.000–0.125 μg / mL. -1 Each well contains 200 μL of bacterial suspension and 100 μL of liquid culture medium as a positive control; well 12 contains 200 μL of liquid culture medium as a negative control.

[0127] Saccharomyces cerevisiae and Staphylococcus aureus were inoculated separately according to the above method, with the Staphylococcus aureus culture medium being liquid broth. The antibacterial test of each drug stock solution was performed in triplicate. The inoculated Candida albicans and Saccharomyces cerevisiae 96-well microculture plates were incubated at 35℃ for 2–3 days, while the Staphylococcus aureus culture plates were incubated overnight at 37℃. Candida albicans ATCC10231 was used as the quality control bacterium and fluconazole as the quality control drug in each experiment. The results were stable and met the standard range specified by NCCLs, indicating that the results of this experiment were reliable. The MICs of each drug against the strains are shown in Table 1. It can be seen that the antibacterial effect of the ciclopirox olamine lotion group was better than that of the solution group and the fluconazole dimethyl sulfoxide solution group. The ciclopirox olamine lotion formulation constructed in this invention has a significantly better in vitro antibacterial effect than the original drug solution, improving the antibacterial performance of the drug.

[0133]

[0134] II. Stability Test

[0135] 1. Accelerated test: Three batches of samples were prepared according to the prescriptions in the above examples and packaged in metal tubes (Shanghai Xinya Pharmaceutical Packaging Materials Factory). The samples were placed at a temperature of 40℃±2℃ and a relative humidity of 75%±5%. Samples were taken at the end of 0, 1, 2, 3 and 6 months respectively, and tested according to the key stability test items.

[0136] 2. Long-term test: Three batches of samples prepared in Example 1 were placed at a temperature of 25℃±2℃ and a relative humidity of 60%±10%, and samples were taken at 3, 6, 9, 12, 18, and 24 months, respectively, and tested according to the key stability observation items. The results show that after 6 months under the above accelerated test conditions, the observed indicators of the samples did not change significantly; after 24 months of long-term testing, the observed indicators of this product also did not change significantly.
