BACKGROUND Lipid-based nanosystems have great potential for transdermal drug delivery. In this study, nanostructured lipid carriers (NLCs) for short-acting alkaloids lappacontine (LA) and ranaconitine (RAN) isolated from Aconitum sinomontanum (AAS) at 69.47 and 9.16% (w/w) yields, respectively, were prepared to enhance percutaneous permeation. Optimized NLC formulations were evaluated using uni...
OBJECTIVE Activated protein C (APC) resistance not related to the factor V Leiden mutation is a risk factor for venous thrombosis. Oral estrogen replacement therapy (ERT) has been reported to induce APC resistance. Little is known about the effect of transdermal estrogen. METHODS AND RESULTS We enrolled 196 postmenopausal women who were randomly allocated to receive either 1 mg 17beta-estradi...
Comment This study showed an unexpectedly high rate (10%) of allergic contact dermatitis to transdermal hyoscine in healthy men treated for several months. Allergic contact dermatitis (type IV delayed hypersensitivity) was diagnosed by well established clinical criteria and was further confirmed by the absence ofany reaction to a placebo patch. Our results contrast with those of studies conduct...
Nanoemulsions have been widely applied to dermal and transdermal drug delivery. However, whether and to what depth the integral nanoemulsions can permeate into the skin is not fully understood. In this study, an environment-responsive dye, P4, was loaded into nanoemulsions to track the transdermal translocation of the nanocarriers, while coumarin-6 was embedded to represent the cargoes. Particl...
Aim: The objective of the present research work was to formulate and compare two different kinds of penetration enhancer in transdermal patch with placebo patch using a drug (Salbutamol sulphate) and compare for in vitro drug release. Study Design: The transdermal patches of Salbutamol sulphate were prepared by solvent evaporation technique using different ratios of Hydroxy propyl methylcellulo...
Ovarian cancer is the fifth most commonly occurring malignancy in women, with the highest mortality rate among all the gynecological tumors. Microparticulate vaccine can serve as an immunotherapeutic approach with a promising antigenic delivery system without a need for conventional adjuvants. In this study, a microparticulate vaccine using whole cell lysate of a murine ovarian cancer cell line...
Objective: To formulate economic transdermal patch of lornoxicam (LX) and to study its anti-inflammatory activity on acute and chronic inflammatory in rat models Method: Three LX transdermal patches (F1, F2 and F3) consist of Eudragit RL-100 and RS-100 in three different ratios (1:2, 1:1 and 2:1) were prepared respectively by the solvent evaporation technique. All formulations contain diethylph...
Worldwide prevalence of type 2 diabetes is increasing with alarming proportions. Metformin is the first-line oral antidiabetic drug of choice for the treatment of type 2 diabetes. The objectives of the present study were to develop Metformin solid lipid nanoparticles (M-SLN) and incorporate it in the transdermal patches. M-SLN was evaluated for Particle size, Zeta potential, Surface morphology ...
BACKGROUND Transdermal progesterone is being used in some countries as a purported treatment for menopausal symptoms, either alone or prescribed in conjunction with estrogen, but little information exists regarding the biological activity and effectiveness of this method of delivery of progesterone in protecting the endometrium from excess proliferation. This study was designed to evaluate the ...
