Zantac vs Maalox
Introduction
For patients experiencing heartburn, indigestion or gastroesophageal reflux disease (GERD), certain medications that act on stomach acid production can provide relief from these conditions. Zantac and Maalox are two such drugs commonly used to manage these symptoms. They each work differently in the body but both aim to reduce discomfort caused by excess stomach acid.
Zantac, also known as ranitidine, is a type of drug called an H2 blocker which works by reducing the amount of acid your stomach produces. On the other hand, Maalox is classified as an antacid and it works by neutralizing existing stomach acid. Both have their pros and cons: while Zantac might be better for long-term management and prevention due to its mechanism of action, Maalox can provide faster relief as it acts directly on the stomach acid.
What is Zantac?
Ranitidine (the generic name for Zantac) is an H2 blocker which was a significant advancement from the first class of antacids, such as Maalox. Ranitidine received FDA approval in 1983 and has been utilized widely to reduce stomach acid production by blocking histamine, thus effectively "trapping" less acid in the stomach over longer periods. It's prescribed mostly for treating ulcers of the stomach and intestines and gastroesophageal reflux disease (GERD). Zantac selectively controls gastric acid secretion with only minor influence on digestive enzymes like pepsinogen, resulting in it having fewer side effects than other antacids that have stronger effects on these other digestion-related components.
What conditions is Zantac approved to treat?
Zantac is approved for the treatment of various gastrointestinal conditions including:
- Gastric and duodenal ulcers, also known as stomach and small intestine ulcers.
- Gastroesophageal reflux disease (GERD), a condition where stomach acid frequently flows back into the tube connecting your mouth and stomach (esophagus).
- Zollinger-Ellison syndrome, a rare disorder characterized by tumors in the pancreas or duodenum that secrete excessive levels of gastrin, leading to overproduction of gastric acid.
How does Zantac help with these illnesses?
Zantac helps to manage conditions such as acid reflux and stomach ulcers by reducing the amount of acid produced in the stomach. It does this by inhibiting a type of cell, known as parietal cells, from producing gastric acid. Gastric acid plays an essential role in digestion but can cause damage and discomfort when produced excessively or when the protective lining of the stomach is compromised. Individuals with conditions like gastroesophageal reflux disease (GERD) or peptic ulcers have an imbalance in gastric acid production relative to their body's ability to protect against it. Therefore, by decreasing gastric acid production, Zantac can limit the negative effects associated with these conditions and help patients manage their symptoms.
On the other hand, Maalox works differently than Zantac. Instead of reducing stomach-acid production, Maalox neutralizes already existing stomach-acid once it has been secreted into your digestive tract. This reduces acidity levels quickly providing fast relief for heartburn sufferers but unlike Zantac isn't typically used long term for chronic conditions like GERD or peptic ulcers since it doesn't address excess-production at its source.
What is Maalox?
Maalox, a brand name for a combination of aluminum hydroxide and magnesium hydroxide, acts as an antacid that neutralizes stomach acid. It was first introduced to the market in 1949. Unlike Zantac (ranitidine), which is part of a class of drugs known as histamine-2 blockers that reduce the production of stomach acid, Maalox works by directly counteracting or neutralizing existing stomach acid.
Its immediate action makes it an effective treatment for occasional heartburn or indigestion symptoms caused by overeating or consumption of certain foods. The side-effect profile is also different from that of H2 blockers like Zantac; while both can cause constipation or diarrhea, Maalox may also lead to hypermagnesemia (a high level of magnesium in the blood) when used excessively. However, it's crucial to note that due to its fast acting nature and lesser probability for systemic absorption compared to ranitidine, it leads less often to serious complications even with prolonged use.
What conditions is Maalox approved to treat?
Maalox is a widely accepted antacid and anti-gas medication that has been approved for the treatment of:
- Heartburn associated with acid indigestion
- Sour stomach brought on by eating or drinking certain foods and beverages. It provides effective relief from these symptoms by neutralizing stomach acid.
How does Maalox help with these illnesses?
Maalox is an antacid medication that plays a critical role in neutralizing stomach acid, providing immediate relief from heartburn and indigestion symptoms. Like Zantac, it also addresses issues of the digestive system but operates on a different mechanism. Maalox works by directly counteracting the acidity in your stomach to alleviate discomfort quickly, while Zantac primarily reduces future acid production. Furthermore, Maalox also contains ingredients with anti-gas properties which may be beneficial if bloating or belching accompanies these symptoms. It's often chosen when patients need quick symptom relief as opposed to long-term management provided by medications like Zantac (ranitidine), or it could potentially be combined with such drugs for comprehensive treatment.
How effective are both Zantac and Maalox?
Both ranitidine (Zantac) and aluminum hydroxide/magnesium hydroxide (Maalox) have established histories of success in treating patients with acid reflux, heartburn, and other conditions caused by excess stomach acid. They were initially approved by the FDA several years apart but have been popular choices for managing gastric acidity since their introduction.
While both medications are effective at reducing stomach acid, they operate through different mechanisms. Ranitidine is an H2 blocker that reduces the amount of acid your stomach produces, while Maalox is an antacid that neutralizes existing stomach acid. The effectiveness of Zantac and Maalox in alleviating symptoms associated with gastroesophageal reflux disease (GERD) has been directly studied; both drugs exhibited similar efficacy as well as promising safety profiles.
A 1986 comparative study demonstrated that ranitidine effectively provides relief from heartburn starting within the first hour or two after treatment initiation, often lasting up to 12 hours[1]. Its side effect profile is generally favorable compared to many other gastrointestinal medications, and it's well-tolerated even in elderly populations[2].
Meanwhile, a review indicated that Maalox offers rapid relief due to its neutralizing action on gastric acidity but may require frequent dosing given its relatively short duration of action[3]. Nonetheless, like Zantac - now largely replaced by safer alternatives due to concerns about potential carcinogenic impurities - Maalox continues to be considered as a first-line option for immediate symptom relief alongside longer-acting treatments such as proton pump inhibitors or H2 blockers.

At what dose is Zantac typically prescribed?
Oral dosages of Zantac range from 75–150 mg, taken up to twice a day. However, research has shown that for the majority of people, a dose of 75 mg is enough to effectively manage heartburn and indigestion symptoms. For Maalox, adults are typically advised to take 10-20 ml per dose (or two to four teaspoons), up to four times daily or as directed by their healthcare provider. Children's dosage will be determined by age and weight and should be given under medical supervision. As with any medication regimen, if there is no symptom relief after several weeks on either drug or symptoms worsen, consult your doctor; never exceed the recommended maximum dosage.

At what dose is Maalox typically prescribed?
Maalox treatment typically begins with a dosage of 5-15 ml per intake. This dose can be taken up to four times daily, ideally an hour after meals and at bedtime for optimal effect in neutralising stomach acid. It's crucial not to exceed the recommended maximum dosage of 60 ml per day unless directed otherwise by your doctor. If there is no significant relief from symptoms such as heartburn or indigestion after several days of consistent use at this level, it would be best to consult your healthcare provider.

- Diarrhea that lasts longer than 2 days
- Irregular heartbeat
In either case if you notice any of these symptoms it's important to stop taking the medication immediately and contact a healthcare professional for advice.
What are the most common side effects for Maalox?
Maalox, an over-the-counter antacid and anti-gas medication, is generally well-tolerated but it may cause certain side effects. These can include:
- A chalky taste in the mouth
- Stomach cramps
- Nausea or vomiting
- Diarrhea or constipation
- Increased thirst
- Headache Despite these possible side effects, most people experience little to no issues when taking Maalox for short-term relief of acid indigestion. However, if any of the above symptoms persist or worsen, it's important to consult a healthcare provider promptly.
Are there any potential serious side effects for Maalox?
While Maalox is generally safe and well-tolerated, it can sometimes cause serious side effects. Be on the lookout for:
- Signs of a severe allergic reaction such as hives; difficulty breathing; swelling of your face or throat
- A significant change in mood or mental state, like confusion or unusual drowsiness
- Severe stomach/abdominal pain, bloody stools
- Slow heartbeat or irregular pulse rate
- Muscle weakness or tremors
- Unusually decreased urination
If any of these symptoms occur after taking Maalox, cease use immediately and consult with your healthcare provider.
Contraindications for Zantac and Maalox?
Both Zantac and Maalox, like most other antacid medications, may exacerbate symptoms of gastrointestinal disorders in some people. If you notice your condition worsening or an increase in stomach pain, persistent nausea/vomiting or bloody stools, please seek immediate medical attention.
Neither Zantac nor Maalox should be taken if you are taking certain antibiotics (like tetracyclines), ketoconazole or atazanavir without discussing with your doctor first due to potential interactions. Always tell your physician which medications you are taking; these drugs might require a specific timing of dosing or avoidance altogether when using Zantac and Maalox.
Furthermore, long term use of these medications can sometimes lead to vitamin B-12 deficiency as they decrease the absorption of this essential nutrient from food. Hence monitoring is necessary for those on prolonged therapy especially among elderly population.
How much do Zantac and Maalox cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Zantac (150 mg) averages around $20, which works out to roughly $0.33/day.
- The price for Maalox Advanced Maximum Strength liquid suspension costs about $10 for a 12 oz bottle. Dosage varies but assuming an average daily dosage of two tablespoons, this works out to approximately $0.40/day.
Thus, if you are in the higher dosage range for Zantac (i.e., 300 mg/day), then brand-name Maalox is less expensive on a per-day treatment basis. Please note that cost should not be your primary consideration when determining which drug is right for you.
For the generic versions of Zantac (ranitidine) and Maalox (magaldrate + simethicone), costs are often lower:
- Ranitidine can be bought in packs ranging from 24 up to many hundreds of tablets with dosages varying between 75 and 150mg per tablet; prices start from as low as $0.15/tablet depending on pack size.
- Generic magaldrate + simethicone suspensions or chewable tablets may also offer savings over branded Maalox products – always check prices at various outlets before making your purchase decision.
Popularity of Zantac and Maalox
Ranitidine, in generic form as well as brand names such as Zantac, was estimated to have been prescribed to about 15 million people in the US before its recall in 2020. It accounted for a significant percentage of antacid prescriptions, and was used commonly to treat conditions like gastroesophageal reflux disease (GERD) and stomach ulcers.
On the other hand, Maalox, an over-the-counter antacid composed of aluminum hydroxide and magnesium hydroxide with simethicone is not typically tracked by prescription data since it does not require one. However, it remains a popular choice amongst consumers for relieving symptoms like heartburn and indigestion due to its immediate effect on neutralizing stomach acid.
It's important to note that while both medications are intended for similar uses such as reducing acidity within the stomach or esophagus they work differently. Ranitidine falls under H2 blockers which reduce acid production whereas Maalox works by directly neutralizing existing acidity.
Conclusion
Both Zantac (ranitidine) and Maalox (a combination of magnesium hydroxide and aluminum hydroxide) have long-standing records of usage in patients with dyspepsia, heartburn, and acid reflux. They are backed by numerous clinical studies indicating that they are more effective than placebo treatments at relieving symptoms associated with these conditions. Due to their different mechanisms of action - Zantac being a histamine-2 blocker reducing the production of stomach acid, while Maalox neutralizes existing stomach acid - they tend to be used under different circumstances.
Zantac is often considered as a first-line treatment option for Gastroesophageal Reflux Disease (GERD), peptic ulcer disease or prevention thereof due to NSAIDs use; whereas Maalox would usually be considered for quick relief from occasional heartburn or indigestion or as an adjuvant therapy to drugs like Zantac.
Both medications are available over-the-counter in generic form which represents significant cost savings especially for those who must pay out-of-pocket. While both Zantac and Maalox can provide relief rather quickly, it might take up a few days for full effect when treating GERD with Zantac.
The side-effect profile is similar between the two drugs: both generally well-tolerated but may cause constipation or diarrhoea. However, prolonged use of ranitidine has been linked to vitamin B12 deficiency. Patients should closely monitor their symptoms when starting treatment and consult immediately if they notice worsening abdominal pain, black stools or vomiting blood.
