Expert Solution
Step 1: Introduction

The term "toxicity" describes a drug's potential harmful  effects or adverse effects on an organism. It is the extent to which a drug can harm body systems like cells, tissues, and organs. Several variables, including dosage, period of use, mode of administration, individual susceptibility, and interactions with other medications, might affect a drug's toxicity.

Toxicity profile is essential to evaluate a drug's safety and develop the proper dose recommendations. Pharmaceutical companies conduct rigorous preclinical and clinical research to assess drug's toxicity and identify potential side effects before a medicine is approved for use. 
In toxicology, the toxicity and therapeutic effects of the drug must be analyzed before finally launching the drug in the market.

The desired or advantageous effects of a drug that are meant to treat or manage a specific condition or disease are referred to as therapeutic effects, also known as pharmacological effects. These outcomes are the beneficial or therapeutic consequences of the drug's interaction with the body.

TD indicates toxic dose that is toxic to a particular organism.
