Phase 2 Drug List Flashcards
Aciclovir - Category
Antiviral
Aciclovir - Reason
Herpes simplex and Varicella zoster infections
Aciclovir - Mechanism
Competitively inhibits viral DNA polymerase to prevent viral DNA replication
Adenosine - Category
Anti-arrhythmic
Adenosine - Reason
Emergency management of superventricular tachycardia (SVT)
Adenosine - Mechanism
Acts as an agonist to reduce production of cAMP. This causes K+ hyperpolarisation in AV node cells which slows conduction
Adrenaline - Category
Alpha & Beta Adrenergic Agonist
Adrenaline - Reason
Anaphylaxis
Adrenaline - Mechanism
- α adrenoceptor activation - peripheral vasoconstriction
- β1 adrenoceptor activation - positive chronotropic and inotropic effects
- β2 adrenoceptor activation - bronchodilatation
Alendronate - Category
Bisphosphonate
Alendronate - Reason
Prophylaxis and treatment of osteoporosis, Paget’s disease
Alendronate - Mechanism
Impairs osteoclast bone resorption by adsorbing onto hydroxyapatite crystals. Promotes osteoclast apoptosis
Allopurinol - Category
Xanthine oxidase inhibitor
Allopurinol - Reason
Prophylaxis of gout and uric acid renal stones
Allopurinol - Mechanism
Inhibits oxidation of xanthine to uric acid, reducing concentration of insoluble uric acid in tissues
