Local anaesthetics can pass into the central nervous system through the blood brain barrier.

With the advent of the HIV and acquired immunodeficiency syndrome that follows infection with HIV, many new antiviral drugs have been introduced since the end of the about how viruses replicate inside cells and how they affect cell function, then no doubt more antiviral drugs will be developed. Antiviral drugs have been developed that work by the following mechanisms: inhibition of the synthesis of viral DNA, RNA and proteins (for example, nucleoside analogues, reverse transcriptase inhibitors, protease inhibitors); reduction in release of viral genetic material once inside the host cell (for example, amantadine); interference with penetration of virus through the cell membrane (for example, neuraminidase inhibitors); interference with attachment of the virus to the host cell membrane (for example, vaccines, immunoglobulins and interferons). Resistance can occur through a number of consequences of viral mutation. There may be reduced phosphorylation of the drug, alteration of viral enzyme targets, or alteration of target channel protein.

Protozoa are microscopic single cell organisms, some of which can infect and cause disease in humans. Pathogenic protozoa are able to evade the hosts immune system by invading host cells. Examples of infections with protozoa include malaria, amoebiasis, leishmaniasis, trypanosomiasis and toxoplasmosis. Most of these infections tend to occur in countries of the developing world rather than in the United Kingdom.

The GABA A receptor is made up of 5 subunits out of a possible 19, and GABA A receptors made up of different combinations of subunits have different properties, different locations within the brain, and, importantly, different activities with regard to benzodiazepines.

This results in effects including reduced anxiety, muscle relaxant, antidepressant and anticonvulsant activity. See also: Benzodiazepine use disorder. Interactive image. Men and women are equally likely to use benzodiazepines recreationally. The more alcohol and alprazolam taken, the worse the interaction.

Like all central nervous system depressants, alprazolam in larger-than-normal doses can cause significant deterioration in alertness and increase drowsiness, especially in those unaccustomed to the drug's effects.
