Atenolol
Nonbenzodiazepine hypnotic, acts via the BZ₁ receptor subtype and is reversed by flumazenil; less amnesia and muscle relaxation and lower dependence liability than benzodiazepines. Zaleplon is similar, but shorter acting.
Zolpidem
Antiviral: prototype NRTI used in combinations for HIV infections and in prophylaxis for needlesticks and vertical transmission. Tox: severe myelosuppresion. Other NRTIs: abacivir, didanosine (ddI), lamivudine (3TC), stavudine (d4T), and zalcitabine (ddC).
Zidovudine (ZDV)
Oral anticoagulant prototype: causes synthesis of nonfunctional versions of the vitamin K-dependent clotting factors (II, VII, IX, X). Tox: bleeding, teratogenic. Antidote: vitamin K, fresh frozen plasma.
Warfarin
