A system and method of electrotherapy for enhanced drug delivery, comprising an electrode patch and an electrotherapy apparatus providing electrical current onto the electrode patch. The electrode patch contains one or more active drug ingredients in a layer of conductive gel, and the electrotherapy apparatus provides electrical current onto the electrode patch for the enhanced drug delivery of active drug ingredients. The conductive gel is in contact with a human or animal body, and the electrode patch also includes a layer of conductive sheet, a supporting layer, and conductive connectors. The conductive gel has the viscosity allowing it to adhere to skin on a human or animal body. The active drug ingredients that can be delivered through the conductive gel include: lidocaine, capsaicin, menthol, camphor, methyl salicylate, trolamine salicylate, Arnica montana, Calendula officinalis, Hypericum perforatum, Symphytum officinale, cannabidiol (CBD) or any combination of these substances. The mass fraction of the active drug ingredients can vary from 0.001% to 30%. The electrotherapy device can be reused.

An electrically stimulated CBD infused pain-relieving patch that is placed on a human's skin that is used to relieve pain when it is connected to a controlled electrical current generating device. The electrically stimulated CBD infused pain-relieving patch comprises of a carrier that has at least one electrode, at least one conductive electrode sheet that is attached to the carrier, and a conductive gel that is placed on the electrode sheet. The conductive gel contains at least one analgesic that is selected from the group consisting of Menthol, CBD, Lidocaine or Capsaicin. The conductive gel has inactive ingredients.

A method and a non-rate controlled, monolithic, subsaturated patch for transdermally administering fentanyl and analogs thereof, for analgetic purposes, to a subject through skin over an extended period of time are disclosed.

A method for treating an influenza virus infection is described. The disclosed method generally involves administering an effective amount of a compound, for example baloxavir marboxil, to a subject having an influenza virus infection and at least one complication risk factor. Generally, the amount is effective such that a reduction in a time to improvement of at leat one symptom of an influenza virus infection is statistically significant as compared to that of a non-treated subject.

The present invention provides the following compounds having anti-viral activity.

##STR00001## A.sup.1 is CR.sup.1AR.sup.1B, S or O; A.sup.2 is CR.sup.2AR.sup.2B, S or O; A.sup.3 is CR.sup.3AR.sup.3B, S or O; A.sup.4 is CR.sup.4AR.sup.4B, S or O; the number of hetero atoms among atoms constituting the ring which consists of A.sup.1, A.sup.2, A.sup.3, A.sup.4, nitrogen atom adjacent to A.sup.1 and carbon atom adjacent to A.sup.1, is 1 or 2; R.sup.1A and R.sup.1B are each independently hydrogen, halogen, alkyl, or the like; R.sup.2A and R.sup.2B are each independently hydrogen, halogen, alkyl, or the like; R.sup.3A and R.sup.3B are each independently hydrogen, halogen, alkyl, or the like; R.sup.4A and R.sup.4B are each independently hydrogen, halogen, alkyl, or the like; R.sup.3A and R.sup.3B may be taken together to form non-aromatic carbocycle or non-aromatic heterocycle; X is CH.sub.2, S or O; R.sup.1 is each independently halogen, hydroxy, or the like; m is any integer of 0 to 2; and n is any integer of 1 to 2.

A method for manufacturing a plurality of pharmaceutical agent delivery patch devices includes: providing a supply web including an active layer containing a pharmaceutically active agent; and cutting the supply web to form cut lines through the active layer. The cut lines define in the active layer: a first active layer patch having a first peripheral edge formed by the cutting step; and a second active layer patch having a second peripheral edge formed by the cutting step. The first and second peripheral edges each include a corner portion. At least a first segment of the first peripheral edge and an opposing second segment of the second peripheral edge are formed by a shared one of the cut lines.

[Problem] If lidocaine is composed of non-aqueous patch, the adhesive power of the preparation tends to get lower, as the composition amount of lidocaine is higher. It is popular to solve lidocaine in dissolving agent in order to compose lidocaine in patch and release effective amount into skin. However, if the amount of dissolving agent gets higher, the adhesive power gets extremely lower, so that an long-time attachment is difficult. [Solution] A non-aqueous patch comprising lidocaine and/or its reactant, and a dissolving agent which are contained in a base of plaster, the plaster being hold by a support, of which strength of 50% stretched to longitudinal direction is less than 2,000 g/50 mm and of biaxially-oriented stretch cloth.

Methods for producing systems for the transdermal or permucosal administration of active substances and particularly transdermal therapeutic systems (TTS), wherein the active substance depots thereof have a shape that deviates from a rectangular design.

The present invention provides a patch containing an adhesive layer maintaining a drug, which is formed on a support, wherein the aforementioned adhesive layer comprises a thermoplastic elastomer, a non-volatile hydrocarbon oil in an amount exceeding 50 parts by weight and not more than 800 parts by weight per 100 parts by weight of the elastomer, and rivastigmine or a salt thereof, and the aforementioned adhesive layer optionally further contains a tackifier at a content in the adhesive layer of not more than 10 wt %.

The present invention provides a pharmaceutical composition containing the following compound having antiviral action: ##STR00001##
wherein each of the symbols is defined in the specification.
