Buprenorphine behaves like a partial agonist/antagonist at µOR. Pentazocine is an antagonist at µOR and an agonist at кOR. Both are classified as “low-ceiling” opioids (B), because neither is capable of eliciting the maximal analgesic effect obtained with morphine or meperidine. The antagonist action of partial agonists may result in an initial decrease in effect of a full agonist during changeover to the latter. Intoxication with buprenorphine cannot be reversed because it binds…

All semisynthetic derivatives (hydromorphone) and fully synthetic derivatives (pentazocine, pethidine = meperidine, l-methadone, and fentanyl) are collectively referred to as opioids. The high analgesic effectiveness of xenobiotic opioids derives from their affinity for receptors normally acted upon by endogenous opioids (enkephalins, в-endorphin, dynorphins;

Baclofen (p- chlorophenyl-GABA) was designed to be an orally active GABA-mimetic agent and is an agonist at GABAB receptors. Activation of these receptors by baclofen results in hyperpolarization, probably by increased K+ conductance

Drugs that modify this reflex arc may modulate excitatory or inhibitory synapses. Thus, to reduce the hyperactive stretch reflex, it is desirable to reduce the activity of the Ia fibers that excite the primary motoneuron or to enhance the activity of the inhibitory internuncial neurons

Pilocarpine is a parasympathomimetic alkaloid obtained from the leaves of tropical American shrubs from the genus Pilocarpus. It is a non-selective muscarinic receptor agonist in the parasympathetic nervous system, which acts therapeutically at the muscarinic acetylcholine receptor M3 due to its topical application, e.g., in glaucoma and xerostomia.

auscultation points for lung lobes (posterior + right side)

Auscultating heart and lung sounds is a fundamental component of a physical assessment. Making sense of what you hear takes knowledge, a sharp ear, and practice.

Hydralazine (apresoline) is a direct-acting smooth muscle relaxant used to treat hypertension by acting as a vasodilator primarily in arteries and arterioles. By relaxing vascular smooth muscle, vasodilators act to decrease peripheral resistance, thereby lowering blood pressure and decreasing afterload.

Type of antidepressant. It is given if the depressed client has not responded to Tricyclic antidepressants and SSRIs. This type of med interacts with a bunch of other meds, thats why its usually not drug of choice for depression. Avoid OTC drugs, especially cold remedies, nasal decongestants, and asthma medications.
