• Indications: PM is used for the treatment of allergic symptoms, often given at night because of its marked sedative effects. Drug hypersensitivity reactions and allergic conditions have also been treated with promethazine especially in emergencies. It can also be used in treating symptoms of asthma, pneumonia, or other lower respiratory tract infections; in fact, inhalation therapy for relieving bronchial spasm is made by quaternary salts of promethazine. PM is sometimes used for its sedative effects and in some countries is marketed for this purpose, including the sedation of young children as nasal sleep introducing drug, or it can be used as an anaesthetic premedication to produce sedation, reduce anxiety, or to reduce postoperative nausea and vomiting as dose-controlled transdermal device. The drug is often given in conjunction with an opiate analgesic such as pethidine, particularly in obstetrics. Taken before travelling, promethazine is effective in preventing motion sickness. Vomiting from other causes can be treated with higher or more frequent doses. Combination of histamine H1R and H4R antagonist is used for the treatment of neoplastic disorders, consisting in a cytotoxic agent as an agent to prevent multidrug resistance[9]. It is also used as a contraceptive killing spermin vagina, since promethazine hydrochloride has strong sperm-killing effect, or as an antimutagenic treatment of bacteria by killing bacteria. Bathing preparation, which contains a histamine H1-antagonist, inhibits the decomposition of hyaluronic acid, playing an important role inmoisture and tension of skin to improve roughened or dried skin. This cosmetic can take such a form as gel, cream, spray, cataplasm, lotion, pack, milky lotion, or powder. It can also be a melanogenesis-suppressing agent useful as a skin-beautifying cosmetic, a skin-aging prevention agent, and so forth, by using a phenothiazine compound having remarkable melanogenesis-suppressing effect. Application of PM can be used for treating haemorrhoids with no pain, no side effect, no operation, and no hospitalization, but low cost[10–12]. Promethazine has been used to control extrapyramidal disorders in children caused by metoclopramide and levodopa-induced dyskinesia in patients with Parkinson’s disease. In young children undergoing dental procedures, it has been suggested that promethazine can be used in conjunction with chloral hydrate to produce sedation, as there was observed a lower incidence of nausea than when chloral hydrate was administered alone. In some countries, promethazine is available as a 2% cream without medical prescription for the treatment of allergic skin conditions, insect bites, and burns.
• Uses: stool softener For the treatment of allergic disorders, and nausea/vomiting. Promethazine is a first generation histamine H1 receptor antagonist (Ki = 2.6 nM) whose antihistamine activity has been reported in guinea pigs and mice at ED50 values of 0.43 and 5.9 mg/kg, respectively. Promethazine can penetrate the CNS, depressing central H1 receptor activity, which may relate to its sedative properties, and can also inhibit muscarinic acetylcholine receptors (Ki = 22 nM). Furthermore, 32 mg/kg promethazine demonstrates antiemetic effects in ferret models of motion sickness or chemotherapy-induced nausea. Promethazine hydrochloride is used as antihistamine; antiemetic; central nervous system depressant; sedative; anticholinergic; antiserotoninergic; local anesthetic; in the treatment of motion sickness, cough linctuses, nausea, and allergic conditions; used to control Parkinsonian symptoms and as central nervous system depressant; in pills, syrup, injections and suppositories.
• Clinical Use: Antihistamine
• Drug interactions: Potentially hazardous interactions with other drugs Analgesics: possibly increased sedative effects.

Ultrasound-assisted removal of Acid Red 17 using nanosized Fe₃O₄-loaded coffee waste hydrochar

10.1016/j.ultsonch.2016.09.004

The research investigates the use of ultrasound-assisted removal of Acid Red 17 (AR17) dye using Fe3O4-loaded coffee waste hydrochar (Fe3O4-CHC) as an adsorbent. The study aims to develop an effective method for treating wastewater containing organic dyes, which pose significant environmental and health risks due to their toxic and carcinogenic effects. The Fe3O4-CHC was synthesized through a simple precipitation method and characterized using various techniques such as SEM, TEM, EDX, XRD, BET, and FT-IR. The results showed that the specific surface area of the hydrochar increased from 17.2 to 34.7 m2/g after loading Fe3O4 nanoparticles, enhancing its adsorption capacity. The ultrasound-assisted process significantly improved the removal efficiency of AR17, achieving 100% decolorization under optimal conditions. The study concluded that Fe3O4-CHC is a promising adsorbent for dye removal, with good stability and reusability, and the high correlation coefficient from the Langmuir model indicated monolayer adsorption of dye molecules on the Fe3O4-CHC surface.
