Zidovudine (ZDV), also known as azidothymidine (AZT), was the first antiretroviral medication used to prevent and treat HIV/AIDS. It is generally recommended for use in combination with other antiretrovirals. [6] It may be used to prevent mother-to-child spread during birth or after a needlestick injury or other potential exposure. [6]
Because of the complexity of selecting and following a regimen, the potential for side effects, and the importance of taking medications regularly to prevent viral resistance, such organizations emphasize the importance of involving patients in therapy choices and recommend analyzing the risks and the potential benefits.

Lamividine/zidovudine is categorized pregnancy category C in the United States, meaning there are potential risks to the baby during pregnancy, but potential benefits may outweigh the risks. [7] Data supports the safety of this combination during pregnancy and is often preferred over other fixed dose combinations during pregnancy.
An action potential occurs when the membrane potential of a specific cell rapidly rises and falls. [1] This depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in several types of excitable cells, which include animal cells like neurons and muscle cells, as well as some plant cells.
A receptor potential can also cause the release of neurotransmitters from one cell that will act on another cell, generating an action potential in the second cell. [4] The magnitude of the receptor potential determines the frequency with which action potentials are generated and is controlled by adaptation, stimulus strength, and temporal ...
Electrotonic potential (or graded potential), a non-propagated local potential, resulting from a local change in ionic conductance (e.g. synaptic or sensory that engenders a local current). When it spreads along a stretch of membrane, it becomes exponentially smaller (decrement). Action potential, a propagated impulse.
A new review reports that nine people taking semaglutide and tirzepatide — the active ingredient in GLP-1 medications — experienced vision issues, including three potentially blinding eye ...
The signal is a short electrical pulse called action potential or 'spike'. Fig 2. Time course of neuronal action potential ("spike"). Note that the amplitude and the exact shape of the action potential can vary according to the exact experimental technique used for acquiring the signal.
