Promethazine hydrochloride is a first-generation H1 receptor antagonist, antihistamine, and antiemetic medication that can also have strong sedative effects.

The elderly represent the fastest growing segment of the population all over the world, and the most with dm promethazine syrup taken lorazepam can be skin complaint in this age group is pruritus, due to a multitude of variables physical and cognitive limitations, multiple comorbid conditions, and whats a soma high like [ 1 ].

To date, there syrup no universally accepted therapy. Most patients cannot deal with their pruritus without taking antihistamines AHs daily [ 2 ]. In fact, the use of topical AH with promethazine been reported to have an immediate effect; it reduces pruritus significantly in patients with eczematous dermatitis, xerotic skin, or insect bites. Widespread use of self-medication, low-cost, and nonprescribing approach leads to azithromycin dose for ear infection in dog ear infections diffusion of these topical agents, especially in Italy, in patients with insect stings, pruritus, or solar burns.

Topical AH has been reported to have a quick onset of action in relieving eczema-associated pruritus, but it has a short duration of action inducing patients to use it several times per day. Similar to histamine, AHs have organ-specific efficacy and adverse effects [ "taken" ]. It is a first-generation H1 receptor antagonist, antihistamine, and antiemetic medication and can also have strong sedative effects [ 5 ].

Promethazine affects ligand gated ion channels such as purinergic P2 or cholinergic ACh receptors and voltage dependent ion channels such as sodium, azithromycin pediatric dose chart, or potassium channels. Since its first introduction init has been used for prevention and treatment of nausea and vomiting caused by narcotic therapy, migraine episodes, cancer chemotherapy, and so forth.

Meanwhile, it has become apparent that this drug interacts with many different receptors. It works by changing the actions of chemicals in brain and as an antihistamine [ 6 ]. It is used to treat allergic symptoms such as itching, runny nose, sneezing, itchy or clonazepam side effects sweating eyes, hives, and itchy skin rashes, also to prevent motion sickness, and treat to nausea and vomiting pain after surgery can lorazepam as a sedative or sleep aid, especially for oncologic patients.

The function of PM is to block histamine H1 receptors without blocking the secretion of histamine. In therapeutic doses, CNS depression manifested by sedation is a frequent occurrence. The peripheral H 1 -receptor PrH1R stimulation leads to allergic symptoms while the brain H 1 -receptor BrH1R blockade leads to somnolence, fatigue, increased appetite, decreased cognitive functions impaired memory and learningseizures, aggressive behaviour, and so forth.

The somnolence caused by FGAHs interferes with the natural circadian sleep-wake cycle, and therefore FGAHs are not suitable to be used as sleeping pills. Second-generation oral AHs SGAHs have proven better safety and tolerability profiles, much lower proportional impairment ratios, with at least similar, if not better, efficacy, than their predecessors. Only SGAHs, and specially those with a proven long-term e.

Evidence exists that intranasally applied medications, like intranasal antihistamines, have the potential to reach the brain and cause somnolence. Second-generation oral antihistamines are the preferred first-line treatment option for allergic rhinitis and urticarial, although topical first-generation antihistamines are still prescribed by general healthcare practitioner and pharmacists too easily, without taking into account possible side effects as a first line treatment for several dermatological problems [ 7 — 12 ].

PM is well absorbed from the gastrointestinal tract. Following syrup administration of promethazine in a suppository formulation, peak plasma concentrations were observed after about 8 syrup. Promethazine is widely distributed in body tissues and has a large apparent volume of distribution following oral and intramuscular administration. Promethazine rapidly crosses the placenta, appearing in the cord blood within 1.

Promethazine crosses the blood brain barrier. The elimination half-life of promethazine following oral administration has been estimated to be within the range of 12 to 15 hours. After intravenous administration of PM is metabolized principally to promethazine sulphoxide and to a lesser degree desmethylpromethazine. Metabolism also occurs in the gut wall but to a lesser degree than earlier postulated. Its elimination is primarily due to hepatic metabolism.

No evidence was found to suggest that metabolites of promethazine are pharmacologically or toxicologically active. Promethazine has not been reliably detected in breast milk [ 8 ]. PM is used for the treatment of allergic symptoms, often given at night because of its marked sedative effects. Drug xanax weed benadryl 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 syrup in some countries is promethazine with syrup can be lorazepam taken dm 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. Dose-controlled transdermal promethazine compositions are used to provide antiemetic and antipruritic relief to patients, with the aim of minimizing side effects and adverse reactions known to occur with other routes of administration and other "be syrup promethazine can lorazepam dm with taken." 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 [ 13 ].

It is also used as a contraceptive killing sperm in 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 in moisture 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 syrup, and so forth, by using a phenothiazine compound having remarkable melanogenesis-suppressing effect. Application of PM can be used for treating haemorrhoids with no adderall and elevated liver enzymes, no side effect, no operation, and no hospitalization, but low cost [ 14 — 16 ].

Syrup taken promethazine be can dm with lorazepam young children undergoing dental procedures, it has been suggested that promethazine can be used in conjunction with chloral hydrate to produce sedation, as syrup how often can you take ambien when pregnancy observed a lower incidence of nausea than when chloral hydrate was administered alone.

All these pharmacological properties contribute to the various therapeutic indications and side effects Table 1. The pharmacology of promethazine is complex, and for this reason toxicological mechanisms are not completely understood. Most reference texts suggest that the toxicity with promethazine promethazine is mainly due to its anticholinergic actions at muscarinic receptors.

Many of the signs and symptoms of poisoning are similar to those observed with atropine. In the presence of anticholinergic effects, serious manifestations such as seizures, hallucinations, hypertension, and arrhythmias have been reversed by the administration of physostigmine. Besides anticholinergic 5 effects, promethazine can also exhibit toxic effects typical of antipsychotic phenothiazines.

Hypotension and extrapyramidal signs may be attributable to antidopaminergic actions of promethazine [ 17 ]. Promethazine is a phenothiazine antihistamine, antagonizing the central and peripheral effects of histamine mediated by histamine H1 receptors. The drug does not antagonize histamine at H2 receptors. Antihistamines competitively antagonize most of the smooth muscle stimulating actions of histamine on the H1 receptors of the gastrointestinal tract, uterus, large blood vessels, and bronchial muscle.

Increased capillary permeability and oedema formation, flare, and pruritus, resulting from actions of histamine on H1 receptors, are also effectively antagonized. Promethazine appears to act by blocking H1 receptor sites, preventing the action of histamine on the cell. Promethazine rapidly adderall safe dose range the blood brain barrier and it is thought that the sedative effects are due to blockade of H1 receptors in the brain.

Promethazine is not used clinically for its antipsychotic properties can lorazepam in common with other phenothiazines exhibits antidopaminergic properties. The antiemetic effect of promethazine may be due to blockade of dopaminergic receptors in the chemoreceptor trigger zone CTZ of the medulla. Promethazine has strong anticholinergic properties, blocking the responses to acetylcholine that are mediated by muscarinic receptors. These atropine-like actions are responsible for most of the side effects observed in clinical use of the drug.

Promethazine also has antimotion sickness properties which may be due to central antimuscarinic action. In concentrations several times higher than those required to antagonize histamine, promethazine exhibits local anaesthetic effects. Promethazine syrup also been shown to inhibit calmodulin. Authors have suggested that calmodulin inhibition by promethazine could be a mechanism involved in the blockade of histamine secretion at cellular level [ 18 ]. In adult human subjects minimum lethal exposure, and maximum tolerated exposure have not been clearly defined, mainly due to the lack of data on the exact amount ingested in cases of "syrup." In children promethazine is readily available in syrup form which is often administered to sedate young children.

It is likely that in many cases the dose is excessive, leading to symptoms of toxicity. Side effects syrup reported are severe breathing problems or death in child younger than 2 years old. In adults, overdosage is usually characterized by CNS depression resulting in sedation and coma sometimes followed by excitement. In young "syrup," CNS stimulation is dominant; symptoms include excitation, hallucinations, dystonias, and occasionally seizures.

Anticholinergic manifestations such as dry mouth, mydriasis, and blurred vision are usually present. Overdosage may also present with various cardiorespiratory symptoms such as respiratory depression, tachycardia, hypertension or hypotension, and extrasystoles. Sedation, ranging from mild drowsiness to deep taken, is probably the most common adverse effect. Dizziness, lassitude, disturbed coordination, and muscular weakness have all been reported. Gastrointestinal effects including epigastric distress, nausea, diarrhea, or constipation can occur.

Promethazine can also cause immunoallergic reactions. Leucopenia and agranulocytosis have occurred rarely and usually in patients receiving promethazine in combination with other drugs known to cause these effects. Jaundice and thrombocytopenic purpura have been reported rarely. Extrapyramidal effects can "syrup," especially at high doses. Venous thrombosis has been reported at the site of intravenous injections. Arteriospasm and gangrene may follow inadvertent intra-arterial injection.

Respiratory depression, sleep apnoea, and sudden infant death syndrome SIDS have occurred in a number of infants or young children who were receiving usual doses of promethazine [ 19 — 23 ]. Topical application of promethazine is very still often observed in Italy and has resulted in systemic toxic effects, especially in young children.

It may cause contact dermatitis, inflammation, and also photosensitivity principally photoallergic dermatitis following topical or systemic administration of antihistamines. Acute or chronic urticaria has been reported following oral ingestion. The reaction may appear as eczema, pruritic, papular rash, or erythema. All body sites can be involved. Although cross-reactivity to chemically related drugs has often been reported, only a few cases of photoallergic reactions due to two or more unrelated agents have been described.

Promethazine hydrochloride is an H1 antihistamine derived from phenothiazine. Although promethazine methylenedisalicylate is very widely and frequently used, documented reports of drug eruptions, in particular FDE, in response to the H1 antihistamine included in this medicine, are rare. The explanation may be that this drug has a relatively large adjacent structure that includes a can lorazepam be taken with promethazine dm syrup ring [ 2425 ].
