Antacids also cause an increase in pH of the urine (alkalization), which may cause increased blood concentrations of weak bases, and increased excretion of weak acids.A proposed method to mitigate the effects of stomach acidity and chelation on drug absorption is to space out the administration of antacids with interacting medications, however this method has not been well studied for drugs affected by urine alkalization.There are concerns regarding interactions between delayed-release tablets and antacids, as antacids may increase the stomach pH to a point at which the coating of the delayed-release tablet will dissolve, leading to degradation of the drug if it is pH sensitive. Formulations
Antacids may be formulated with other active ingredients such as simethicone to control gas, or alginic acid to act as a physical barrier to acid. Liquids
Several liquid antacid preparations are marketed. Common liquid preparations include milk of magnesia and magnesium/aluminum combinations. A potential advantage of using a liquid preparation over a tablet is that liquids may provide quicker relief, however this may coincide with a shorter duration of action. Tablets
Chewable tablets
Chewable tablets are one of the most common forms of antacids, and are readily available over-the-counter. Upon reaching the stomach, the tablet powder will dissolve in the stomach acid, allowing the cations to be released and neutralize excess stomach acid. Common salts available in tablet form include those of calcium, magnesium, aluminum, and sodium.Some common brand are Tums, Gaviscon chewable tablets and Maalox chewable tablets.
If not reduced quickly, prolapses in pigs become necrotic and infected, and risk being cannibalized by other pen mates. If the latter happens it normally results in death of the animal by sepsis, shock or faecal peritonitis. Horses and mules
Rectal prolapse occurring in horse and mule would be better termed anal prolapse, as it only involves mucous membrane moving posteriorly to form a circular protrusion outside the anus  The condition is not painful. In mares after parturition, it is described as a 10 to 60 mm mucous protrusion.In young mules and foals, anal prolapse occurs with a frequency similar to that of Gasterophilus haemorrhoidalis. In extensive breeding conditions, the disease is only recognized after some days, leading to intense edema of prolapsed tissues and necrosis of the mucous membrane. Early cases in should be treated with the application of hygroscopic substances like powdered sugar followed by purse-string suturing. When prolapsed tissues are edematous and necrotic, amputation is performed. The prognosis is fair as the removed tissues do not contain any important organs or large blood vessels. References
