Drug toxicity can manifest in various forms, including:
1. Acute Toxicity: Adverse effects that occur shortly after a single dose or multiple doses within a short period. 2. Chronic Toxicity: Adverse effects resulting from long-term exposure to a drug, even at therapeutic doses. 3. Organ-Specific Toxicity: Damage to specific organs such as the liver, kidneys, or heart. 4. Carcinogenicity: The potential of a drug to cause cancer. 5. Teratogenicity: The potential of a drug to cause developmental defects in a fetus.
