"Scientists at the National Institutes of Health report they have discovered in mouse studies that a small molecule released in the spinal cord triggers a process that is later experienced in the brain as the sensation of itch.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
In the controlled clinical trials, adverse events were monitored in the 161 subjects who used TRI-LUMA Cream once daily during an 8-week treatment period. There were 102 (63%) subjects who experienced at least one treatment-related adverse event during these trials. The most frequently reported events were erythema, desquamation, burning, dryness, and pruritus at the site of application. The majority of these events were mild to moderate in severity. Adverse events reported by at least 1% of patients and judged by the investigators to be reasonably related to treatment with TRI-LUMA Cream from the controlled clinical trials are summarized (in decreasing order of frequency) as follows:
Table 1: Incidence and Frequency of Treatment-related
Adverse Events with TRI-LUMA Cream in at Least 1% or More of Subjects (N=161)
|Adverse Event||n (%)|
|Pigmentary changes||3 (2%)|
|Acne-like rash||1 (1%)|
|Dry mouth||1 (1%)|
The following local adverse reactions have been reported with topical corticosteroids. They may occur more frequently with the use of occlusive dressings, especially with higher potency corticosteroids. These reactions are listed in an approximate decreasing order of occurrence: burning, itching, irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, skin atrophy, striae, and miliaria.
