Pharmacokinetics describes what the body does to a drug: absorption, distribution, metabolism and excretion (ADME).

The autonomic nervous system regulates smooth muscle, cardiac muscle and glands. All autonomic preganglionic neurons release acetylcholine onto nicotinic neuronal (Nn) receptors.

MCQ tip: Thiazides reduce urinary calcium excretion; loop diuretics increase it. Heparin-induced thrombocytopenia (HIT) is important because it causes thrombocytopenia with a paradoxically increased…

Coverage varies by individual drug; generation alone does not predict all susceptibility. Dental exam tip: Clindamycin is associated with C.

Dental relevance: NSAIDs are useful for inflammatory dental pain when suitable; paracetamol is an alternative or adjunct. Choose according to the patient's medical history and contraindications.

Antidote: Naloxone, with repeat dosing or infusion when needed because some opioids outlast naloxone. May occur with combinations of serotonergic drugs.


General anesthetics produce reversible unconsciousness and other components of anesthesia, such as amnesia and immobility.

Important: Flumazenil can precipitate seizures in benzodiazepine-dependent patients or mixed overdoses; it is not a universal antidote for an unconscious patient.

A prodrug is a pharmacologically inactive (or weakly active) compound that is converted into an active, functional drug inside the body after administration.
