Here we report a novel approach for preparation of a 6-day transdermal drug delivery system (TDDS) as treatment for mild to moderate Alzheimer’s disease. The spray drying method was used to prepare microparticles containing the anti-Alzheimer drug. The content of the drug was determined by High Performance Liquid Chromatography (HPLC) method. The morphology and size range of the microparticles ...

Drug delivery system relates to the production of a drug, its delivery medium, and the way of administration. Drug delivery systems are even used for administering nitroglycerin. Transdermal drug delivery system is the system in which the delivery of the active ingredients of the drug occurs by the means of skin. Various types of transdermal patches are used. There are various methods to enhanc...

The purpose of this study was to develop a reservoir-type transdermal delivery system for isosorbide dinitrate (ISDN). The developed patch consisted of five layers from bottom to top, namely, a temporary liner, an adhesive layer, a rate-controlling membrane, a reservoir and a backing. The effects of chemical penetration enhancers, reservoir materials and rate-controlling membranes on the releas...

Recently, decreased activity levels have been observed in pigs treated postoperatively with transdermal delivery of fentanyl (TD-fentanyl) after isoflurane anaesthesia. Whether the change in behaviour is related to opioid-induced sedation or to insufficient pain relief remains to be investigated. This study was therefore undertaken to evaluate the effect of TD-fentanyl 50 microg h(-1) on the ac...

Imperfect use of contraceptive methods notably increases the likelihood of pregnancy. One means of improving user adherence with hormonal contraception is to minimize the dosing schedule. Two forms of hormonal contraceptive have currently achieved this goal: the transdermal patch and the vaginal ring. The first and only transdermal contraceptive patch to receive worldwide regulatory approval (e...

Melatonin, a pineal gland hormone can play an important role on circadian rhythms and worked as an internal sleep facilitator in human. Recently, melatonin was used as a drug for treatment of insomnia. The transdermal drug delivery is a good alternative for melatonin delivery because of its variable oral absorption, short half-life, highly first pass metabolism, and a favorable partition coeffi...

OBJECTIVE To investigate compliance, satisfaction, and preference in women using a transdermal contraceptive patch. METHODS Women (18-46 years) from eight European countries used contraceptive patches (norelgestromin 6 mg, ethinylestradiol 600 μg) for six, 4-week treatment cycles. Compliance, satisfaction, and preference were assessed after 3 and 6 cycles and study completion using self-repor...

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...

UNLABELLED CASE HISTORY AND PRESENTATION: Two non-human primates (Macaca fascicularis), weight 3.5 kg, enrolled in an experimental protocol received a 25 μg hour(-1) transdermal fentanyl patch for postoperative analgesia. The following day both animals were clinically normal, but after a new induction of anaesthesia with ketamine, they developed severe and prolonged respiratory distress, profou...
