Effects During Pregnancy and Lactation
◉ Overview of Use During Lactation Occasional use of small doses of Carbinoxamine during lactation may be acceptable. Larger doses or prolonged use may cause drowsiness and other adverse reactions in infants, or reduce milk production, especially when used in combination with sympathomimetic drugs (such as pseudoephedrine) or before lactation is fully established. Because Carbinoxamine has been shown to cause serious toxicity in children under 2 years of age, the manufacturer recommends avoiding breastfeeding while taking Carbinoxamine. Non-sedating antihistamines are a better alternative. ◉ Effects on Breastfed Infants There are currently no reports of breastfeeding infants while mothers are taking Carbinoxamine. In a telephone follow-up study, mothers reported that 10% of infants exposed to various antihistamines experienced irritability and colic, and 1.6% experienced drowsiness. All reactions did not require medical attention. ◉ Effects on Lactation and Breast Milk Higher doses of antihistamines can lower basal serum prolactin levels in non-lactating women and early postpartum women. However, pre-administration of antihistamines by postpartum mothers does not affect suckling-induced prolactin secretion. Whether lower doses of oral carbizamine have the same effect on serum prolactin, and whether changes in prolactin levels have any impact on breastfeeding success, is currently unknown. For mothers who have established lactation, prolactin levels may not affect their ability to breastfeed. |

| Additional Infomation |
Carbinoxamine maleate is the maleate salt of Carbinoxamine. It is an ethanolamine antihistamine used to treat hay fever and mild Parkinson's disease. It has a dual role as an H1 receptor antagonist, antihistamine, muscarinic receptor antagonist, and anti-Parkinson's disease agent. Its molecular structure contains Carbinoxamine. Carbinoxamine maleate belongs to the ethanolamine class of H1 antihistamines and has mild antimuscarinic and sedative effects. Carbinoxamine reduces the typical effects of histamine on H1 receptors in bronchial smooth muscle, capillaries, and gastrointestinal smooth muscle, including vasodilation, bronchoconstriction, increased vascular permeability, pain, itching, and spastic contractions of gastrointestinal smooth muscle. Carbinoxamine maleate is used to relieve allergy symptoms.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.14 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.14 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
