Agonist actions at opioid receptor Less abuse potential than opioids Pentazocine (Talwin) Analgesic Weak antagonist effects at opioid receptor. Agonist actions at opioid receptor Respiratory depression at low dose BUT has ceiling effect i.e. not dose dependent. Low abuse potential. High doses – dysphoria and psychomimetic effects

Define agonist, partial agonist and antagonist drugs in terms of affinity and efficacy. Agonist – a drug capable of binding to and activating a receptor. A full agonist has affinity for its receptor and full efficacy. Partial agonist – can occupy all of the receptors but cannot elicit a maximal response.

Agonist- medication that causes stimulation of receptors. Antagonist: Medication that binds to a receptor and blocks other medications or chemicals from attaching there. Action: therapeutic effect that a medication has. Indications- reasons for giving a particular medication. Contraindications- reasons for potentially withholding a medication

Receptor antagonist - Wikipedia
The antagonist [B] and agonist [D] are competing for the same limited number of receptors [R]. The drug that binds to the receptor in the highest concentration will be determined by two factors. These factors are the affinities of the agonist and antagonist for the receptor and their relative concentrations.
