Current Drug Delivery Strategies for Buccal Cavity Ailments using Mouth Dissolving Wafer Technology: A Comprehensive Review on the Present State of the Art

BACKGROUND

Mouth-dissolving wafer is polymer-based matrice that incorporates various pharmaceutical agents for oral drug delivery. This polymeric wafer is ingenious in the way that it needs not be administered with water, like in conventional tablet dosage form. It has better compliance among the pediatric and geriatric groups owing to its ease of administration.

OBJECTIVE

The polymeric wafer dissolves quickly in the oral cavity and is highly effective for a targeted local effect in buccal-specific ailments. It is a safe, effective, and versatile drug delivery carrier for a range of drugs used to treat a plethora of oral cavity-specific ailments that inflict common people, like thrush, canker sores, periodontal disease, benign oral cavity tumors, buccal neoplasm, and malignancies. This review paper focuses thoroughly on the present state of the art in mouth-dissolving wafer technology for buccal drug delivery and targeting. Moreover, we have also addressed present-time limitations associated with wafer technology to aid researchers in future developments in the arena of buccal drug delivery.

CONCLUSION

This dynamic novel formulation has tremendous future implications for designing drug delivery systems to target pernicious ailments and diseases specific to the buccal mucosa. In a nutshell, this review paper aims to summarize the present state of the art in buccal targeted drug delivery.

Nystatin Effectiveness in Oral Candidiasis Treatment: A Systematic Review & Meta-Analysis of Clinical Trials

Oral candidiasis is the most common opportunistic fungal infection caused by commensal Candida species. Since there are various local and systemic predisposing factors for the disease, the treatment also varies from topical to systemic antifungal agents. Nystatin is a common antifungal agent used topically. The aim of this systematic review was to evaluate and compare the efficacy of different antifungal agents and the safety of nystatin in the treatment of oral candidiasis. Three electronic databases were searched for randomized controlled trials comparing nystatin with other anti-fungal therapies or placebo. Clinical and/or mycological cure was the outcome evaluation. A meta-analysis and descriptive study on the efficacy, treatment protocols, and safety of nystatin was also conducted. The meta-analysis included five studies, which compared the efficacy of nystatin suspensions with photodynamic therapy. A significant difference in the colony-forming units per milliliters (CFU/mL) of Candida species was observed at 60 days intervals for both palatal mucosa and denture surfaces, with both groups favoring nystatin with low heterogeneity at a 95% confidence interval. Nystatin and photodynamic therapy were found to be equally effective for the clinical remission of denture stomatitis as well as a significant reduction of CFU/mL of Candida species from dentures and palatal surfaces of the patients.

Comparison of topical antifungal agents for oral candidiasis treatment: a systematic review and meta-analysis

OBJECTIVE

To compare the efficacy and safety of topical antifungal drugs for oral candidiasis in adults and children.

STUDY DESIGN

Databases were searched from their inception to December 2020. The inclusion criterion was randomized controlled trials comparing topical antifungal agents. The primary outcomes were clinical response and mycological cure rates. The secondary outcomes were adverse reaction incidence and relapse rate.

RESULTS

In adults with oral candidiasis, fluconazole showed a better clinical response rate than clotrimazole (P = 0.001; risk ratio [RR], 1.14), but a similar mycological cure rate (P = 0.57; RR, 1.03). There was no significant difference in clinical response and mycological cure rates with either fluconazole and amphotericin B (clinical: P = 0.47, RR, 0.96; mycological: P = 0.99, RR, 1.00) or with either itraconazole and clotrimazole (clinical: P = 0.51, RR, 1.06; mycological: P = 0.45, RR, 1.32). For immunocompetent patients, fluconazole was superior to clotrimazole in terms of clinical response rate. For immunosuppressed patients, clotrimazole and itraconazole presented similar clinical response and mycological cure rates, but the relapse rate with itraconazole was lower than that with clotrimazole. In infants, miconazole and nystatin showed similar clinical response rates (P = 0.36; RR, 1.23), whereas miconazole presented a superior mycological cure rate (P = 0.03; RR, 4.03).

CONCLUSIONS

Fluconazole and amphotericin B are recommended as topical antifungal agents for adults with oral candidiasis. Existing studies tend to recommend fluconazole for immunocompetent patients and itraconazole for immunosuppressed patients, whereas miconazole is recommended for infants.

Efficacy and safety of miconazole for oral candidiasis: a systematic review and meta-analysis

The objective of this study is to assess the efficacy and safety of miconazole for treating oral candidiasis. Twelve electronic databases were searched for randomized controlled trials evaluating treatments for oral candidiasis and complemented by hand searching. The clinical and mycological outcomes, as well as adverse effects, were set as the primary outcome criteria. Seventeen trials were included in this review. Most studies were considered to have a high or moderate level of bias. Miconazole was more effective than nystatin for thrush. For HIV-infected patients, there was no significant difference in the efficacy between miconazole and other antifungals. For denture wearers, microwave therapy was significantly better than miconazole. No significant difference was found in the safety evaluation between miconazole and other treatments. The relapse rate of miconazole oral gel may be lower than that of other formulations. This systematic review and meta-analysis indicated that miconazole may be an optional choice for thrush. Microwave therapy could be an effective adjunct treatment for denture stomatitis. Miconazole oral gel may be more effective than other formulations with regard to long-term results. However, future studies that are adequately powered, large-scale, and well-designed are needed to provide higher-quality evidence for the management of oral candidiasis.

Conquering common breast-feeding problems

Meeting mothers' personal breast-feeding goals depends on a number of factors, including the timely resolution of any problems she encounters. Nurses are often the first providers who interact with the mother during the perinatal period and are positioned to guide mothers through the prevention and solving of breast-feeding problems. Although many problems may be "common," failure to remedy conditions that cause pain, frustration, and anxiety can lead to premature weaning and avoidance of breast-feeding subsequent children. This article describes strategies and interventions to alleviate common problems that breast-feeding mothers frequently encounter.

Fluconazole for postpartum candidal mastitis and infant thrush

This case report illustrates the difficulties inherent in treating candidal mastitis in lactating women and concurrent thrush in the breastfeeding baby. This mother's candidiasis vacillated from topical to ductal, depending on which medications were being used over the course of several months. Her baby's oral thrush was unique in that there were never any white plaques visible on his oral mucosa. Ultimately, both mother and child were treated simultaneously with oral fluconazole, with a relief of symptoms in both individuals.

Mammary candidosis in lactating women

Though perceived to be a growing problem by lactation professionals, fungal infection of the breast (mammary candidosis) is largely unstudied. Candida albicans, a commensal organism encountered frequently in the vagina and gastrointestinal tract of humans, has been reported to be responsible for both superficial (cutaneous) and localized (ductal) infection of the mammary gland in lactating women, though the latter association is not universally accepted. Severe pain is considered to be characteristic of yeast infection of the breast and may be a cause of premature weaning among lactating mothers. Given that pain is often the complaint that prompts mothers to consult lactation professionals, it is important that healthcare providers working with lactating women be knowledgeable about this disease. In this article, current research regarding yeast infection of the breast is summarized, including morphology and pathology, diagnosis, risk factors, and common treatment options.

Treatment of oropharyngeal candidiasis in immunocompetent infants: a randomized multicenter study of miconazole gel vs. nystatin suspension. The Antifungals Study Group

BACKGROUND

Miconazole gel has previously been shown to be an effective treatment for oropharyngeal candidiasis (thrush) in immunocompetent infants. This study compares miconazole gel with the standard therapeutic agent, nystatin suspension, with regard to efficacy, optimal duration of therapy and safety.

DESIGN

Prospective multicenter, randomized, office-based open trial.

PATIENTS

Twenty-six pediatricians enrolled 227 immunocompetent infants with signs of oropharyngeal thrush. Subjects were randomly assigned to receive 25 mg of miconazole as oral gel four times daily or 100,000 IU of nystatin as suspension four times daily after meals. All subjects were evaluated for safety. Fifteen patients whose thrush was not confirmed by culture were excluded from further analysis. The remaining 212 subjects were entered into an intention-to-treat analysis. Another 29 patients violated the study protocol; the remaining 183 subjects were evaluated for efficacy (per protocol analysis).

RESULTS

Clinical cure by Day 5 of treatment was demonstrated in 84.7% of the 98 subjects in the miconazole group and 21.2% of the 85 subjects in the nystatin group (P < 0.0001). By Day 8, the cumulative clinical cure rates were 96.9% (miconazole) and 37.6% (nystatin), respectively (P < 0.0001). By Day 12.99.0% of subjects in the miconazole group and 54.1% of subjects in the nystatin group were clinically cured (P < 0.0001). Premature cessation of treatment at parents' request because of lack of clinical efficacy occurred in none of the infants treated with miconazole and in 6 infants treated with nystatin (P = 0.029). The oral yeast eradication rate on Day 5 was 54.1% with miconazole and 8.2% with nystatin (P < 0.0001). Clinical relapses of oropharyngeal thrush and side effects of the study drugs were observed with similar frequency in both study arms.

CONCLUSIONS

Miconazole gel was significantly superior to nystatin suspension with regard to efficacy, rapidity of achieving cure and oropharyngeal yeast eradication. Relapses and side effects did not occur more frequently with miconazole than with nystatin. The results of this study indicate that miconazole gel is superior to nystatin suspension as the treatment for oropharyngeal candidiasis in immunocompetent infants.
