Its activity at other receptors may contribute to this.

Another example is morphine, which mimics the actions of endorphins at μ-opioid receptors throughout the central nervous system.

These peptides are all released centrally and act on other neurons at specific receptors.

Cyprenorphine has mixed agonist-antagonist effects at opioid receptors, like those of buprenorphine.

Other agents may have more direct effects at receptors.

Some currently common drugs that have been classed as partial agonists at particular receptors include:

The drugs are aimed at receptors in cells that regulate fat and sugar.

Noise mitigation strategies exist to reduce sound levels at nearby sensitive receptors.

It is directed at receptors in the suprachiasmatic nucleus, which sets the body's internal clock.
