Final answer:
An enteric-coated tablet or pill is designed to mask objectionable odors or tastes and protect the drug from stomach acid, ensuring that it dissolves in the intestines. Chirality plays a crucial role in the effectiveness of a drug due to the chiral nature of the body's receptors.
Step-by-step explanation:
The drug form where a drug has a special coating to mask objectionable odor or taste is known as an enteric-coated tablet or pill. This special coating is designed to survive the acidic environment of the stomach and only dissolve in the less acidic environment of the intestines. This protects the drug from being destroyed by stomach acid and also helps mask any unpleasant taste or odor.
The concept of chirality is important in pharmacology because it can affect the way a drug interacts with the body. Due to the chiral nature of the body's receptors, the molecules of a drug must match the chiral binding sites, which can influence taste, flavor, odor, and drug action. Moreover, the development of drugs sometimes aims to increase their efficacy against a wider variety of bacteria, improve stability, decrease toxicity, and confer other beneficial properties for treating infections.
