ADVERSE DRUG REACTIONS = undesirаble, unintended, mоstly hаrmful effects during usuаl drug use ADR CLASSIFICATION (Type A–E) Type A (Augmented) Dоse-related, predictable• Based оn pharmacologic action• Most commonExamples:– Hypoglycemia (antidiabetics)– Bleeding (anticoagulants) Type B (Bizarre) Not dose-related, unpredictable• Often immune-mediated or geneticExamples:– Antibiotic hypersensitivity reactions Type C (Chronic) Occur with long-term use• Reversible in many casesExamples:– Dry cough (ACE inhibitors) Type D (Delayed) Occur after prolonged exposure or latency• Often irreversibleExamples:– Tardive dyskinesia (antipsychotics) Type E (End of therapy) Occur after drug withdrawal• Rebound or withdrawal effectsExamples:– Opioid withdrawal syndrome IATROGENIC REACTIONS• Drug-induced disease caused by therapeutic use• Often predictable and preventableExamples: Salicylates → peptic ulcer IDIOSYNCRASY• Rare, unpredictable reaction at therapeutic dose• Not related to pharmacologic action or dose• Often genetic (enzymes/receptors)Examples: Sulfonamides → hemolysis in G6PD deficiency MUTAGENICITY & CARCINOGENICITY• DNA damage → cancer risk• Often long-term exposure relatedExamples: Estrogens → endometrial cancer risk INTOLERANCE• Low threshold to drug effects• Occurs even at normal or low dosesExamples: Chloroquine → nausea, vomiting, abdominal pain TOXIC EFFECTS• Exaggerated pharmacologic effect• Dose-related, predictable• More likely with overdose or accumulationExamples: Aminoglycosides → nephrotoxicity, ototoxicity DRUG DEPENDENCEPsychological dependence (habituation)• Compulsive use for perceived well-beingExamples: caffeine, tobacco Physical dependence• Physiologic adaptation to drug• Withdrawal if stoppedExamples: morphine Drug addiction• Combined psychological + physical dependence• Compulsive drug-seeking behaviorExamples: morphine DRUG WITHDRAWAL (ABSTINENCE) SYNDROME• Rebound worsening after abrupt discontinuation• Prevented by gradual taperingExamples: opioids TERATOGENICITY• Fetal structural/functional defects during pregnancy exposureExamples: valproic acid → neural tube defects DRUG HYPERSENSITIVITY• Immune-mediated reaction to drug or metabolite• Drug acts as hapten → immune activation• Not dose-dependent• Cross-reactivity may occurExamples: penicillin allergy PHOTOSENSITIVITY• Requires drug + light interaction• Skin reactions on exposure to UV light Phototoxic reaction More common• Dose-dependent sunburn-like response• Limited to exposed areasExamples: NSAIDs, tetracyclines, sulfonamides Photoallergic reaction Delayed, immune-mediated (cell-mediated)• Eczematous rash, pruritus• Can spread beyond exposed areasExamples: topical NSAIDs, fragrances Question: A patient develops hemolysis after receiving a normal therapeutic dose of sulfonamides due to a rare genetic enzyme deficiency, which type of adverse drug reaction (ADR) does this represent?
