Final answer:
An enteric-coated tablet is resistant to gastric juices and dissolves in the intestine. The oral route is convenient for home administration of antimicrobials. The tablet's journey starts in the mouth where it is unaffected by chewing and mixing with food.
Step-by-step explanation:
The tablet with a special coating that resists disintegration by gastric juices is called an enteric-coated tablet. This type of tablet is designed to bypass the stomach without being dissolved by the stomach acid and release its active ingredient in the intestine where it's less likely to irritate. Regarding the appropriate and convenient route for home administration of an antimicrobial to treat a systemic infection, the oral route is typically preferred. Tablets or capsules can be taken at home without the need for complex procedures like intravenous injections which are more invasive and generally require medical supervision. The journey that the capsule takes begins in the mouth. As illustrated, the capsule experiences a series of movements and interactions, including being surrounded by different food components and experiencing the cutting and grinding action of teeth. Despite these conditions, the enteric-coated tablet remains intact until it reaches the desired part of the gastrointestinal tract.
