A stability indicating RP-HPLC-UV assay method for the simultaneous determination of hydroquinone, tretinoin, hydrocortisone, butylated hydroxytoluene and parabens in pharmaceutical creams
Overview
The provided study details the development and validation of a novel stability-indicating Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC-UV) method. This procedure was specifically designed for the simultaneous determination of six distinct components within topical pharmaceutical creams: hydroquinone (HQ), tretinoin (TRT), hydrocortisone acetate (HCA), butylated hydroxytoluene (BHT), methyl paraben (MP), and propyl paraben (PP).
Methodology
- The chromatographic separation is achieved using an X-Bridge C18 column (150 x 4.6 mm, 5 µm) utilizing a gradient elution profile.
- The mobile phase flow rate was optimized to 1 mL/min to ensure complete separation of analytes with similar polarities.
- Analytes were detected at a wavelength of 280 nm, which provided a satisfactory response for all six constituents without causing unacceptable baseline noise.
Validation Results
The analytical method was rigorously validated in accordance with the International Conference of Harmonization (ICH) Guidelines.
- The intra- and interday precision was excellent, showing a relative standard deviation (RSD) of less than 2.0% for all analytes.
- The method’s trueness, evaluated through mean percentage recovery, fell within the highly accurate range of 100% to 102% for most components.
- Calibration curves demonstrated exceptional linearity, with correlation coefficients greater than 0.9992 for all six components.
- System suitability tests (SST) verified complete separation, with all peak resolutions exceeding 1.5.
Forced Degradation Findings
The researchers subjected the standard solutions to harsh environmental conditions to prove the method’s capability as a stability-indicating assay.
- Acid Degradation: Exposure to acidic conditions slightly affected HCA and BHT, resulting in a 91% recovery rate.
- Alkaline Degradation: Basic conditions drastically destroyed HCA, reducing its recovery to just 5.5%, and moderately degraded BHT to 85%.
- Oxidative Degradation: Treatment with hydrogen peroxide caused an intensification of the BHT peak, increasing it to 130%.
- Photodegradation: Exposure to UV radiation primarily impacted the stability and quantity of TRT.
Application and Environmental Assessment
The validated procedure was successfully applied to analyze Tritospot cream, a commercially available product, yielding satisfactory precision and trueness. To measure the method’s environmental impact and practicality, the researchers evaluated it using the AGREEprep and BAGI metrics. The BAGI evaluation confirmed the method is highly practical for routine quality control in pharmaceutical industries. Meanwhile, the AGREEprep tool indicated that the method’s “greenness” could be further improved by transitioning from manual, ex situ sample preparations to automated, online approaches.

Treatment of melanoma in-transit metastases with combination intralesional interleukin-2, topical imiquimod, and tretinoin 0.1% cream
Overview
The provided case report details the management of challenging melanoma in-transit metastases using a triple-combination therapy. The treatment protocol utilized intralesional interleukin-2 (IL-2) combined with topical imiquimod and tretinoin 0.1% cream.
Patient Profile and Clinical Challenges
- A 64-year-old man presented with recurrent melanoma on his right ear, which eventually necessitated ear amputation and lymph node dissection.
- The patient possessed significant comorbidities that restricted standard systemic treatment options: active Crohn’s disease contraindicated the use of ipilimumab, a history of depression with suicidal ideation precluded systemic high-dose IL-2, and his tumor lacked a BRAF mutation.
- After an initial response to chemotherapy, the patient experienced a recurrence, developing more than ten new in-transit metastases around the periphery of his right ear graft site.
Treatment Regimen
- The patient was treated with high-dose intralesional IL-2 injections twice a week.
- Alongside the injections, topical imiquimod and tretinoin 0.1% cream were applied simultaneously once a day to all visible lesions, including a 5-cm peripheral margin.
- Following a robust inflammatory response at two weeks, the IL-2 dose was maintained at 11 million units per injection.
Clinical Outcomes
- Side effects, which included transient chills, nausea, and local skin inflammation, were well-tolerated by the patient.
- After exactly five weeks of therapy (comprising 10 IL-2 injections), the patient achieved complete clinical resolution of all visible in-transit metastases.
- Following clearance, intralesional IL-2 was discontinued, and the patient was transitioned to a maintenance regimen of topical imiquimod and tretinoin applied for seven consecutive days each month.
- While the patient’s skin remained clear of melanoma metastases for nine months, he subsequently developed systemic metastases in the bone, liver, and lungs, ultimately electing for comfort care.
Mechanisms of Action and Conclusions
- The success of this regimen is attributed to the distinct, synergistic mechanisms of each agent: IL-2 activates natural killer cells and T cells, imiquimod stimulates antitumoral cytokines via toll-like receptors, and tretinoin modifies keratinocyte maturation to enhance the epidermal penetration of imiquimod.
- The study concludes that mid- to high-dose intralesional IL-2, when combined with topical imiquimod and tretinoin cream, is an effective and appealing therapeutic option for cutaneous melanoma metastases.
- This combination is particularly valuable for patients who have disease limited to locoregional recurrences, possess severe comorbidities, or have contraindications to systemic immunotherapies.

Systemic isotretinoin with topical tretinoin cream in the treatment of multiple warty dyskeratomas
Overview
- This case report documents the successful medical management of multiple warty dyskeratomas (WD).
- WD most commonly presents as a single nodule on the head or neck, which allows for simultaneous diagnosis and treatment through excisional surgery.
- Instances of multiple WDs are extremely rare, with only six prior case reports published and very little information available regarding effective medical treatments.
Patient Presentation
- A 29-year-old Taiwanese man initially presented with a single painful red nodule on his right cheek, which was excised and histopathologically confirmed as a WD.
- Two years after the initial excision, the patient developed hundreds of keratotic papules and nodules exhibiting follicular plugging.
- These widespread lesions were distributed across his scalp, face, neck, and chest.
- A subsequent biopsy of a scalp lesion confirmed the diagnosis of typical WD.
- The patient had no personal or family history of other skin disorders, such as Darier’s disease.
Treatment Regimen and Rationale
- The patient was treated with systemic oral isotretinoin at a dosage of 30 mg per day, administered in three divided doses.
- This systemic therapy was concurrently combined with the application of topical 0.05% tretinoin cream.
- Systemic isotretinoin was selected because WD is a disorder involving epidermal proliferation, and multiple WDs share pathogenic features with acne vulgaris and Darier’s disease.
- Because isotretinoin effectively modulates keratinocyte maturation and alters epidermal proliferation, it is theoretically well-suited to treat extensive WD lesions.
Clinical Outcomes
- After just one month of this combination therapy, the patient showed a dramatic and significant improvement in both the size and the number of lesions.
- The patient reported mild dry mouth as the only adverse reaction to the treatment.
- Treatment was discontinued after 14 weeks due to the cost of the medication and the side effect.
- During a 5-month follow-up period after stopping the medications, the therapeutic effects were maintained.
- The majority of the patient’s lesions remained small during the follow-up, and only a few new lesions developed.
