Fexofenadine HCl and fexofenadine are essentially the same medication, with fexofenadine HCl being the hydrochloride salt form of fexofenadine. The addition of the hydrochloride salt increases the solubility of the drug, making it easier to formulate into oral dosage forms such as tablets or syrups. In terms of pharmacological activity, both forms are equally effective in treating Allergies by blocking the action of histamine at the H1 receptor.
No, fexofenadine HCl is the active ingredient in Allegra, while Allegra-D contains fexofenadine HCl and pseudoephedrine. Pseudoephedrine is a decongestant that is added to Allegra-D to help relieve nasal congestion in addition to allergy symptoms.
No, fexofenadine HCl is an antihistamine used to treat allergies. It is not chemically suitable or designed for the synthesis of methamphetamine. Attempting to use it for this purpose is illegal and dangerous.
my pharmacist says they are the same thing.. i just called him b/c i was prescribed the HCL this time and I was wondering why...
Yes, HCl has a dipole-dipole interaction because it is a polar molecule. The difference in electronegativity between hydrogen and chlorine creates a permanent dipole moment in the molecule, leading to dipole-dipole attractions between neighboring HCl molecules.
0.1M HCl refers to a solution with a concentration of 0.1 moles of HCl per liter of solution, whereas 0.1N HCl refers to a solution with a normality of 0.1. Normality takes into account the chemical equivalent weight of a substance, so for HCl with a 1:1 mole ratio, the molarity and normality values would be the same.

The spelling.
There is not much of a difference between the two of these. They are diphenhydramine in different salt forms but will have the same effect. Diphenhydramine citrate will be slightly more readily absorbed in the body than HCl.
what is the difference between metformin and metformin HCL
my pharmacist says they are the same thing.. i just called him b/c i was prescribed the HCL this time and I was wondering why...
The dipole moment of HCl is determined by calculating the product of the charge difference between the hydrogen and chlorine atoms and the distance between them. This results in a vector quantity that represents the polarity of the molecule.

From what i have researched , the difference is that pseudoephedrine HCI has 16% pseudoephedrine HCL. You can read more on the following website http:/www.dow.com/dowexcipients/resources/pseu.htm
No it is not

The main difference is in composition. In TE common Tris buffer is bring down to pH 8 with HCl and EDTA is involved but in TAE instead of Tris HCl in TE Tris-acetate buffer is used.
