Pidotimod is a synthetic dipeptide with immunomodulatory properties.

Ebastine (Kestine) (trade names Evastin, Kestine, Ebastel, Aleva) is a non-sedating H1 antihistamine. It does not penetrate the blood-brain barrier and thus allows an effective block of the H1 receptor in peripheral tissue without a central side effect, i. e not causing sedation or drowsiness.

Diethyl fumarate, a decomposition product of the pesticide Malathion, causes nonimmune contact urticaria on the skin.

Mizolastine (SL 850324) (IC50= 47 nM) is a histamine H1-receptor antagonist.It is used in the treatment of allergic reactions such as hay fever (seasonal allergic rhinitis), hives.

Remibrutinib inhibits BTK activity with an IC50 value of 0.023 μM in blood. Remibrutinib is an effective and orally active Bruton tyrosine kinase inhibitor (IC50: 1 nM). Remibrutinib has the potential for Chronic urticaria (CU) treatment.

Leukotriene C4 (LTC4) is an arachidonate lipid mediator that regulates leukocyte recruitment and function at sites of inflammation.Leukotriene C4 is a mediator of bronchoconstriction, mucus hypersecretion, and eosinophilia, and has a mediating role in urticaria.

Hydroxyzine Pamoate (Bobsule) is a histamine H1 receptor antagonist that is effective in the treatment of chronic urticaria, dermatitis, and histamine-mediated pruritus. Unlike its major metabolite CETIRIZINE, it does cause drowsiness. It is also effective as an antiemetic, for relief of anxiety and tension, and as a sedative.

Cetirizine dihydrochloride (UCB P071) is an effective second-generation histamine H1 antagonist that is potent in the therapy of allergic rhinitis, confirmed urticaria, and pollen-induced asthma. Unlike other conventional antihistamines, it does not cause side effects of drowsiness or anticholinergic.

Dexchlorpheniramine Maleate (S-(+)-Chlorpheniramine maleate salt) is an antihistamine with anticholinergic properties used to treat allergic conditions such as hay fever or urticaria. It is the pharmacologically active dextrorotatory isomer of chlorpheniramine.

Loratadine (SCH 29851) is a second-generation histamine H1 receptor antagonist used in the treatment of allergic rhinitis and urticaria. Unlike most classical antihistamines (HISTAMINE H1 ANTAGONISTS) it lacks central nervous system depressing effects such as drowsiness.

Fexofenadine hydrochloride (Terfenidine carboxylate hydrochloride) is a second generation antihistamine that is used for the treatment of allergic rhinitis, angioedema and chronic urticaria.

Chlorpheniramine maleate (NCI-C55265) is a histamine H1 antagonist used in allergic reactions, hay fever, rhinitis, urticaria, and asthma.

Hexyl nicotinate (AI3 15769) is a cutaneous vasodilator and can be used in research on non-immunologic contact urticaria on the scalp, face, and back.

Fexofenadine (Carboxyterfenadine), an antihistamine pharmaceutical drug, is used to treat allergy symptoms, such as nasal congestion, hay fever, and urticaria. Compared to first-generation antihistamines, Fexofenadine is less able to pass the blood-brain barrier and cause sedation.

Hydroxyzine dihydrochloride (Hydroxyzine 2HCl) is a histamine H1 receptor antagonist that is effective in the treatment of chronic urticaria, dermatitis, and histamine-mediated pruritus. Unlike its major metabolite CETIRIZINE, it does cause drowsiness. It is also effective as an antiemetic, for relief of anxiety and tension, and as a sedative.

Levocetirizine Dihydrochloride (Xyzal Dihydrochloride) is a third-generation peripheral H1-receptor antagonist. Acting as an antihistaminic agent, it specifically targets the histamine H1-receptor. Levocetirizine Dihydrochloride is the R-enantiomer of Cetirizine, which gives it a higher affinity for the H1-receptor than the S-enantiomer. Due to this enhanced affinity, Levocetirizine Dihydrochloride is effective in treating allergic rhinitis and chronic idiopathic urticaria.

Dexchlorpheniramine Maleate, a histamine receptor antagonist, is used to treat urticaria, allergic rhinitis, allergic conjunctivitis and pruritus.

Astemizole (Laridal) is a synthetic piperidinyl-benzimidazol derivative with antiallergic properties, acts as a reversible competitive inhibitor of histamine H1 receptors, with less anticholinergic effects compared to related agents. It is a long-acting, non-sedative antihistaminic used in the treatment of seasonal allergic rhinitis, asthma, allergic conjunctivitis, and chronic idiopathic urticaria.

Mrgx2 antagonist-3 (Compound B-40) is a highly selective antagonist of the MrgX2 receptor, with an IC50 range of 0.042-2.5 nM. It blocks downstream G protein signaling and β-arrestin recruitment, inhibiting Mrgx2 receptor-mediated calcium influx and cell degranulation. Mrgx2 antagonist-3 shows potential for research in inflammation-associated diseases and pruritus, such as chronic urticaria and allergic asthma.

Triprolidine hydrochloride anhydrous, a Histamine H1 antagonist, is used in asthma, allergic rhinitis, and urticaria.

Carbinoxamine, an anticholinergic and antihistamine agent, is used for hay fever, angioedema, vasomotor rhinitis, mild urticaria, dermatographism and allergic conjunctivitis. It is a histamine antagonist, specifically an H1-antagonist.
