    Study Notes

    Drug Information Study Notes

    • Drug Characteristics: This data presents various drugs, categorized by injection type (INJECT) or non-injection (NP) method of administration. Each drug is listed with its generic and brand names, pharmacologic category (e.g., DMARD, corticosteroid), and potential side effects.

    Drug Properties & Use Cases

    • Mechanism of Action (MOA): This section details how each drug works at a molecular level. Examples include binding to TNF-alpha to block inflammation, inhibiting calcium ion entry to relax blood vessels, or blocking specific receptors.

    • Box Warnings: Some drugs have serious warnings, such as potential for serious infections, sepsis, or malignancy. These "black box" warnings highlight potentially life-threatening side effects.

    • Therapeutic Uses: This section outlines the specific conditions a drug is intended to treat. Examples include arthritis, acne, elevated intraocular pressure, and hypertension.

    • Renal Adjustments/Controlled Substances: A subset of drugs require dosage adjustments based on kidney function (marked with 'X') and others may be controlled substances (specified where applicable).

    • Common Side Effects: Frequently reported side effects are listed for each medication; examples include rash, headache, nausea, and dizziness.

    • Administration Information: This category may include injection site reactions, special instructions, etc. for administering the medicine.

    Detailed Drug Examples

    • adalimumab (Humira): A TNF-blocking agent used for Crohn's disease, arthritis, and psoriasis; carries warnings about serious infections.

    • adapalene (Differin): A retinoid derivative used for acne vulgaris, often associated with skin dryness.

    • benzoyl peroxide: Used for acne; potential side effects include skin irritation.

    • Bimatoprost (Durysta, Latisse, Lumigan): An ophthalmic prostaglandin, typically used to treat elevated intraocular pressure (glaucoma) and hypotrichosis (eyelash loss).

    • Hydroxyzine (Atarax/Vistaril): An H1 antagonist, mainly used for anxiety; common side effect is drowsiness.

    • Infliximab (Remicade): A TNF-blocking agent, used similarly to adalimumab for conditions like Crohn's and Arthritis, carrying infection risks.

    • Lidocaine (Solarcaine): A local anesthetic, with life-threatening risks in young children.

    • Prednisone (Deltasone): A corticosteroid used for inflammation, with potential side effects like insomnia.

    • Atenolol (Tenormin): A beta-blocker; often used in treating heart conditions like acute MI; includes discontinuation warnings.

    • Atorvastatin (Lipitor): An HMG-CoA reductase inhibitor, frequently prescribed to help lower cholesterol levels and prevent cardiovascular disease.

    • Amlodipine (Norvasc): A calcium channel blocker for angina and hypertension.

    • aspirin Provides pain relief, fever reduction, and anti-inflammatory effects but also has considerable gastrointestinal risks.

    • Several drugs (e.g., various loop diuretics, ACE inhibitors, beta-blockers, etc. ) are listed for treating hypertension, edema, and cardiac conditions; specific mechanisms of action are available for each.
