The Transfersome® is a lipid vesicle that contains membrane softeners, such as Tween 80, to make it ultra-deformable. This feature makes the Transfersome® an efficient carrier for delivery of therapeutic drugs across the skin barrier. It was reported that TDT 067 (a topical formulation of 15 mg/ml terbinafine in Transfersome® vesicles) has a much more potent antifungal activity in vitro compare...

The aim of this study was to evaluate the in vivo activity of itraconazole and terbinafine for treating experimental cutaneous sporotrichosis. Eighty Wistar rats were used, divided into four groups (TERB20, TERB30, ITRA and CONT). They were inoculated in the left plantar pad with 0.2 ml of solution containing 2x10(3) cell/ml of Sporothrix schenckii and treated with terbinafine (20 and 30 mg/kg)...

Terbinafine Hydrochloride (TH) is a new potent antifungal agent. UV-spectrophotometric method has been developed for the determination of TH in bulk and in tablet dosage form. For the determination of Terbinafine Hydrochloride, solvent system employed was methanol and wavelength of detection was 223 nm. The aim of this study was to develop simple, sensitive, cost effective, accurate, precise, r...

OBJECTIVES The activity in vitro of terbinafine against 442 clinical isolates of several species of filamentous fungi was analysed. METHODS A broth microdilution test was carried out following the National Committee for Clinical Laboratory Standards reference method, with modifications described previously. RESULTS The geometric mean (GM) of MICs of terbinafine for non-Aspergillus fumigatus...

Since terbinafine was introduced on the world market 17 years ago, it has become the leading antifungal for the treatment of superficial fungal infections, aided by unique pharmacologic and microbiologic profiles. This article reviews mode of action, antimycotic spectrum and disposition profile of terbinafine. It examines the data, accumulated over 15 years, on the comparative efficacy of terbi...

Terbinafine Hydrochloride (TH) is a new potent antifungal agent. Many spectroscopic methods are developed using organic solvents, but inorganic solvents like hydrochloric acid, sodium hydroxide can also be used for the estimation of APIs depending on their solubility. UV-spectrophotometric method has been developed for the determination of TH in bulk and in tablet dosage form. For the determina...

Terbinafine is a recommended therapeutic alternative for patients with sporotrichosis who cannot use itraconazole due to drug interactions or side effects. Melanins are involved in resistance to antifungal drugs and Sporothrix species produce three different types of melanin. Therefore, in this study we evaluated whether Sporothrix melanins impact the efficacy of antifungal drugs. Minimal inhib...

Superficial mycoses caused by Trichophyton rubrum are among the most common infections worldwide. T. rubrum infections are difficult to treat and are often associated with recurrences after interruption of the antifungal therapy. Nevertheless, reports on T. rubrum resistance to commonly used antifungal drugs are rare. In this study, we compared the in vitro resistance frequencies and developmen...

Terbinafine, an allylamine used to treat onychomycosis, has been reported to be active against rat Pneumocystis carinii in vitro and in vivo. By contrast, our in vitro data showed that the 50% inhibitory concentration of terbinafine against rat P. carinii is 3.7 microg/ml, a level that cannot be clinically achieved in serum. In the present study, terbinafine administered orally at doses of 20 t...

In the present study we used two groups of Candida dubliniensis strains: one containing fluconazole-susceptible clinical isolates and another containing fluconazole-resistant laboratory derivative from the former to examine the changes on susceptibility accompanying the development of resistance to fluconazole. Our findings confirmed the ability of C. dubliniensis isolates to become resistant t...
