Sometimes considered to be better tolerated as it may cause less gastrointestinal side effects. However, the monohydrate version is more expensive and it may be not absorbed as well as the hyclate version depending on stomach pH. For these reasons, the hyclate version is often preferred.MetoprololToprol XL (metoprolol succinate extended release)Lopressor (metoprolol tartate)Metoprolol succinate is available in an extended release formula while metoprolol tartrate is only available as an immediate release product. In addition, metoprolol succinate may be more effective in reducing mortality in heart failure patients than the tartrate salt and is therefore preferred over it in that population.HydroxyzineAtarax (hydroxyzine hydrochloride)Vistaril (hydroxyzine pamoate)It has been reported that hydroxyzine pamoate is more lipid soluble, and therefore has more sedative effects than hydroxyzine hydrochloride. This has led to hydroxyzine hydrochloride (Atarax) being used more often for allergic symptoms and itching (as it is an antihistamine), with hydroxyzine pamoate (Vistaril) being used more often for anxiety symptoms and insomnia. Whether these differing effects are clinically significant is not well known.MagnesiumMagnesium carbonateMagnesium chlorideMagnesium citrateMagnesium salts differ in many characteristics including elemental magnesium content per dose, absorption, tolerability and overall effects on the body.How Are Drugs With Salts Listed On Your Prescription LabelUnfortunately, most pharmacies in the United States use different software and the consistency in listing drug names is not there. One pharmacy may dispense Lipitor as atorvastatin calcium, while another may simply list atorvastatin. This can create even more confusion if your pharmacy switches generic manufacturers of a drug on you. For example, it isn't uncommon for a pharmacy to dispense 'amlodipine besylate' one month, but then switch the manufacturer of the product (as there are numerous) and dispense 'amlodipine' the next. They are the same drug compound (amlodipine besylate) but for whatever reason, the pharmacy software lists them differently.If you ever have any questions regarding your prescription (especially if there is more than one salt form available!), be sure to speak with your pharmacist.
