Pediatric onychomycosis management is challenging as there are limited treatment options. The objective of this study was to evaluate efinaconazole 10% topical solution in children with onychomycosis. leer más
In two phase III clinical trials of patients with moderate-to-severe acne (NCT02932306, NCT02965456), tretinoin 0.05% lotion reduced inflammatory and noninflammatory lesions relative to vehicle lotion, with low potential for cutaneous irritation. leer más

BACKGROUND: Tazarotene has been extensively studied in clinical trials and is widely used to treat acne vulgaris (acne), with data suggesting that is one of the most potent topical retinoids. Irritation from the cream, foam, and gel formulations has limited its use in clinical practice. OBJECTIVE: To assess the efficacy, safety, and tolerability of a unique tazarotene 0.045% lotion formulation based on polymeric emulsion technology in subjects with moderate or severe acne. Methods: A total of 1614 subjects, 9 years and older were randomized to receive tazarotene 0.045% lotion or vehicle in two identical double-blind, randomized, vehicle-controlled 12-week studies evaluating safety and efficacy (inflammatory [papules and pustules] and noninflammatory [comedonal] lesion counts and using Evaluator Global Severity Scores [EGSS]). Treatment success was defined as at least a 2-grade improvement in EGSS and ‘clear’/’almost clear’ and efficacy assessed through reduction in lesion counts. In addition, patients completed a validated Acne-Specific Quality of Life (Acne-QoL) questionnaire. Safety, adverse events (AEs), and cutaneous tolerability were assessed throughout. RESULTS: Tazarotene 0.045% lotion demonstrated statistically significant superiority to vehicle in reducing inflammatory and noninflammatory lesion counts at week 12. Mean percent reductions in inflammatory and noninflammatory lesions were 55.5% and 51.4% (Study 1, both P<0.001 versus vehicle [45.7% and 41.5%, respectively]) and 59.5% and 60.0% (Study 2, both P<0.001 versus vehicle [49.0% and 41.6%, respectively]), with tazarotene 0.1% cream at week 12. Treatment success was achieved by 25.5% (Study 1) and 29.6% (Study 2) of subjects treated with tazarotene 0.045% lotion (both P<0.001 versus vehicle [13.0% and 17.3%, respectively]). Improvements in QoL domain scores were consistently greater with tazarotene. Tazarotene 0.045% lotion was well-tolerated. The most common treatment-related AEs were application site pain (5.3%), dryness (3.6%), and exfoliation (2.1%). CONCLUSION: Tazarotene 0.045% lotion provides statistically significant greater efficacy than vehicle in terms of lesion reduction and treatment success, with a highly favorable safety and tolerability profile in moderate-to-severe acne patients.

Successful clinical data on halobetasol propionate 0.01%/tazarotene 0.045% (HP/TAZ) lotion in moderate-to-severe plaque psoriasis are published. This article charts its formulation development. Dermal deposition, clinical efficacy, and synergistic effect of HP and TAZ delivered by polymeric emulsion technology was compared to HP 0.05% cream (Ultravate) and TAZ 0.1% cream (Tazorac); skin hydration and barrier maintenance with vehicle lotion through Trans Epidermal Water Loss (TEWL) and corneometry using human cadaver tissue; and steroid potency by vasoconstrictor assay (VCA) in healthy volunteers. Safety and tolerability evaluated in clinical studies and patient preference questionnaire. HP/TAZ lotion, using polymeric emulsion technology demonstrated better active ingredient delivery than HP 0.05% or TAZ 0.1% creams; supported by synergistic clinical data, with high HP potency outcome. Efficacy was rapid and sustained posttreatment. Layering TAZ 0.1% cream onto HP 0.05% cream had a negative effect on receptor phase levels. HP/TAZ lotion provided rapid and sustained increases in skin moisturization and gradually decreases in TEWL. Most subjects responded favorably to questions on the physical attributes of the vehicle lotion. Fixed combination HP 0.01%/TAZ 0.045% lotion formulation utilizing innovative polymeric emulsion technology and optimal selection of solvents/emollients/humectants, has recently been developed. Features inherent in technology translate into rapid, sustained efficacy, low irritation, and good patient acceptance. leer más
Large population-based surveys by the Government of India and several other regional studies have reconfirmed the coexisting burden of over- and undernutrition. While time trends from the 2, 3 and 4 rounds of the National Family Health Survey show declining trends in the prevalence of the underweight, it also highlights increasing rates in the overweight/obesity. Dose-response relationships with different micro- and macronutrient consumption with overweight/obesity prevalence have been established. In this context, it was attempted to identify the specific diet pattern and socio-behavioural determinants of overnutrition along with its combat strategies. This review highlights that while the proportion of chronic energy deficiency is decreasing in India, the intake of micronutrients and food groups continues to be below the recommended dietary allowance set by the Indian Council of Medical Research. Distal factors that determine the nutritional imbalance among Indians are presented under (i) household contextual factors, (ii) peer and socio-cultural influencers, and (iii) business and neighbourhood environment. Accumulation of such factors increases the density of obesogenic environment around individuals. Further, the review offers action points at individual, society and policy levels, presented in a 'logframe matrix' for bringing convergence actions across sectors in consultation with programme managers from different ministries/departments. leer más
