What are ammonium chloride enteric-coated tablets?

AMMONIUM CHLORIDE (Ammonium Chloride Enseals®) is an acid-forming salt that can help correct situations in which the blood contains too little chloride or is too alkaline (basic). This can occur following vomiting, suctioning (removal) of stomach contents, use of diuretics (water or fluid pills), or with certain stomach disorders. Ammonium chloride also causes mild diuresis (removal of excess salts and water through increased urination) and makes the urine more acidic. Ammonium chloride also has been used to reduce the swelling, bloating, or weight gain that occurs before menstrual periods; and as an aid to treating urinary tract infections. Generic ammonium chloride tablets are available.

What should I tell my health care provider before I take this medicine?

They need to know if you have any of these conditions:
• fluid on the lungs
• high levels of chloride in the blood
• kidney disease
• liver disease
• metabolic acidosis
• an unusual or allergic reaction to ammonium chloride, other medicines , foods, dyes, or preservatives

How should I take this medicine?

Take ammonium chloride tablets by mouth. Follow the directions on the prescription label. Swallow the tablets whole with a drink of water; do not crush or chew. Do not take ammonium chloride with antacids or milk. Take your doses at regular intervals. Do not take your medicine more often than directed.

Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.

What if I miss a dose?

If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.

What drug(s) may interact with ammonium chloride?

• acetazolamide
• potassium salts
• sodium salts

Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

What should I watch for while taking ammonium chloride?

If you are taking nonprescription dosage forms, do not take for more than one week without consulting your prescriber or health care professional. Ammonium chloride can cause serious side effects and is not recommended for long-term use.

Columbia Encyclopedia: ammonium chloride
(əmō'nēəm klôr'īd) , chemical compound, NH4Cl, a white or colorless, odorless, water-soluble, cubic crystalline salt with a biting taste, commonly known as sal ammoniac. It is prepared commercially by reacting ammonia, NH3, with hydrogen chloride, HCl, and is used chiefly in the manufacture of electric dry-cell batteries, in soldering fluxes, in textile printing, and in making other compounds. It is also used in certain medical treatments. It occurs in nature in volcanic regions.

Ammonium chloride (NH4Cl) (also Sal Ammoniac, salmiac, nushadir salt, zalmiak, sal armagnac, sal armoniac, salmiakki, salmiak and salt armoniack) is, in its pure form, a clear white water-soluble crystalline salt with a biting, slightly sour taste. The aqueous ammonium chloride solution is mildly acidic.

History

The modern name "ammonium" comes from sal ammoniac. The substance was known as nushadir salt (Arabic and Persian: نشادر) in Arabic-speaking countries and Persia, naosha (Chinese: 硇砂; pinyin: náoshā) in China, nao sadar in India.

It was considered one of the four alchemical "spirits". While the way that it dissociates into two corrosive materials (ammonia and hydrochloric acid) which attack metals convinced some eager alchemists that it might hold the key to converting one metal to another, Arabs used it as a source of ammonia:

2NH4Cl + 2CaO → CaCl2 + Ca(OH)2 + 2NH3

Sources

In nature, the substance occurs in volcanic regions, forming on volcanic rocks near fume-releasing vents. The crystals deposit directly from the gaseous state, and tend to be short-lived, as they dissolve easily in water.

Ammonium chloride is prepared commercially by reacting ammonia, NH3, with hydrogen chloride, HCl:

NH3 + HCl → NH4Cl

Applications

Ammonium chloride is sold in blocks at hardware stores for use in cleaning the tip of a soldering iron and can also be included in solder as flux.

Other uses include a feed supplement for cattle, in hair shampoo, in textile printing, in the glue that bonds plywood, as an ingredient in nutritive media for yeast, in cleaning products, and as cough medicine. Its expectorant action is caused by irritative action on the bronchial mucosa. This causes the production of excess respiratory tract fluid which presumably is easier to cough up. It is the active ingredient in many antiperspirants, usually aerosols. It is also used in an oral acid loading test to diagnose distal renal tubular acidosis.

Ammonium chloride is used in snow treatment, namely on ski slopes at temperatures above 0 °C, to harden the snow and slow its melting.[1]

In several countries sal ammoniac is used to spice up liquorice-type dark candies (Finland's salmiakki and the Netherlands' zoute drop and the Danish Dracula Piller are popular examples), and as a flavoring for vodkas.
