Botulinum toxin, or botulinum neurotoxin, is a highly potent neurotoxic protein produced by the bacterium Clostridium botulinum and related species. It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis. The toxin causes the disease botulism. The toxin is also used commercially for medical and cosmetic purposes. Botulinum toxin is an acetylcholine release inhibitor and a neuromuscular blocking agent.
Iontophoresis is a process of transdermal drug delivery by use of a voltage gradient on the skin. Molecules are transported across the stratum corneum by electrophoresis and electroosmosis and the electric field can also increase the permeability of the skin. These phenomena, directly and indirectly, constitute active transport of matter due to an applied electric current. The transport is measured in units of chemical flux, commonly μmol/(cm2*hour). Iontophoresis has experimental, therapeutic and diagnostic applications.
Hyperhidrosis is a condition characterized by abnormally increased sweating, in excess of that required for regulation of body temperature. Although primarily a benign physical burden, hyperhidrosis can deteriorate quality of life from a psychological, emotional, and social perspective. In fact, hyperhidrosis almost always leads to psychological as well as physical and social consequences. People suffering from it present difficulties in the professional field, more than 80% experiencing a moderate to severe emotional impact from the disease and half are subject to depression.
Glycopyrronium bromide is a medication of the muscarinic anticholinergic group. It does not cross the blood–brain barrier and consequently has few to no central effects. It is given by mouth, via intravenous injection, on the skin, and via inhalation. It is a synthetic quaternary ammonium compound. The cation, which is the active moiety, is called glycopyrronium (INN) or glycopyrrolate (USAN).
Pregabalin, sold under the brand name Lyrica among others, is an anticonvulsant, analgesic, and anxiolytic amino acid medication used to treat epilepsy, neuropathic pain, fibromyalgia, restless leg syndrome, opioid withdrawal, and generalized anxiety disorder (GAD). Pregabalin also has antiallodynic properties. Its use in epilepsy is as an add-on therapy for partial seizures. It is a gabapentinoid medication and acts by inhibiting certain calcium channels. When used before surgery, it reduces pain but results in greater sedation and visual disturbances. It is taken by mouth.
Sorafenib, sold under the brand name Nexavar, is a kinase inhibitor drug approved for the treatment of primary kidney cancer, advanced primary liver cancer, FLT3-ITD positive AML and radioactive iodine resistant advanced thyroid carcinoma.
Oxybutynin, sold as under the brand name Ditropan among others, is an anticholinergic drug primarily used to treat overactive bladder. It is widely considered a first-line therapy for overactive bladder due to its well-studied side effect profile, broad applicability, and continued efficacy over long periods of time. It works similar to tolterodine, darifenacin, and solifenacin, although it is usually preferred over these medications. It is sometimes used off-label for treatment of hyperhidrosis, or excessive sweating. It has also been used off-label to treat bed wetting in children, but this use has declined, as it is most likely ineffective in this role. It is taken by mouth or applied to the skin.
Bretylium (also bretylium tosylate) is an antiarrhythmic agent. It blocks the release of noradrenaline from nerve terminals. In effect, it decreases output from the peripheral sympathetic nervous system. It also acts by blocking K+ channels and is considered a class III antiarrhythmic. The dose is 5–10 mg/kg and side effects are high blood pressure followed by low blood pressure and ventricular ectopy.
Naldemedine is a medication that is used for the treatment of opioid-induced constipation in adults with chronic non-cancer pain. It is a peripherally acting μ-opioid receptor antagonist and was developed by Shionogi. Clinical studies have found it to possess statistically significant effectiveness for these indications and to be generally well tolerated, with predominantly mild to moderate gastrointestinal side effects. Effects indicative of central opioid withdrawal or impact on the analgesic or miotic effects of co-administered opioids have only been observed in a small number of patients.
Focal hyperhidrosis, also known as primary hyperhidrosis, is a disease characterized by an excessive sweating localized in certain body regions. Studies suggest that this condition, affecting between 1% and 3% of the US population, seems to have a genetic predisposition in about two thirds of those affected.
Aluminum chloride hexahydrate, sold under the brand name Hydrosal Gel among others, is a first-line treatment for excessive sweating.
Indacaterol/glycopyrronium bromide, sold under the brand name Ultibro Breezhaler among others, is a fixed-dose combination medication for inhalation consisting of the following two active ingredients:
Niraparib, sold under the brand name Zejula, is an anti-cancer medication used for the treatment of epithelial ovarian, fallopian tube, or primary peritoneal cancer. It is taken by mouth. It is a PARP inhibitor.
Dextromethorphan/bupropion (DXM/BUP), sold under the brand name Auvelity, is a combination medication for the treatment of major depressive disorder (MDD). Its active components are dextromethorphan (DXM) and bupropion. Patients who stayed on the medication had an average of 11% greater reduction in depressive symptoms than placebo in an FDA approval trial. It is taken as a tablet by mouth.
Beclometasone/formoterol/glycopyrronium, sold under the brand name Trimbow among others, is an inhalable fixed-dose combination medication for the treatment of chronic obstructive pulmonary disease (COPD) and asthma. It contains beclometasone dipropionate, formoterol fumarate dihydrate, and glycopyrronium bromide.
Cefiderocol, sold under the brand name Fetroja among others, is an antibiotic used to treat complicated urinary tract infections when no other options are available. It is indicated for the treatment of multi-drug-resistant Gram-negative bacteria including Pseudomonas aeruginosa. It is given by injection into a vein.
Aluminium sesquichlorohydrate is an aluminium salt that is used as an antiperspirant agent, a deodorant agent, and a cosmetic astringent. Aluminium sesquichlorohydrate works by physically blocking eccrine sweat glands.
Glycopyrronium bromide/formoterol, sold under the brand name Bevespi Aerosphere, is a combination medication for the maintenance treatment of chronic obstructive pulmonary disease (COPD). It is a combination of glycopyrronium bromide and formoterol. It is inhaled.
Budesonide/glycopyrronium bromide/formoterol, sold under the brand name Breztri Aerosphere among others, is an inhalable fixed-dose combination medication for the treatment of chronic obstructive pulmonary disease (COPD). It contains budesonide, glycopyrronium bromide, and formoterol fumarate dihydrate. It is inhaled.
