Anti-cholinergic drugs were originally used prior to the development of levodopa because many signs of excessive parasympathetic activity are seen in Parkinsons patients (salivation, sweating and incontinence). The basal nuclei contain many excitatory cholinergic neurons. As the nigrostriatal tract progressively degenerates, the release of inhibitory dopamine declines and the cholinergic system becomes relatively overactive. The site of action of anti-cholinergic drugs appears to be at muscarinic receptors in the basal nuclei. However, as the disease progresses, the loss of dopaminergic activity becomes so great that anti-cholinergic drugs cannot compensate for it.

The cell wall of gram-negative bacteria does not contain as much of this mucopolysaccharide and they do not take up the gram stain. The cell wall of gram-negative bacteria is complex and includes an outer double lipid layer, which limits susceptibility to some antibiotics. Broad-spectrum antibiotics are effective against most bacteria, whereas narrow spectrum antibiotics may be effective against only some. The use of broad-spectrum antibiotics can reduce populations of normal flora (the resident harmless bacteria that we all have), which can cause adverse effects and superinfections of fungi and other drug-resistant micro-organisms.

Antiviral drugs work by inhibiting the synthesis of viral DNA, RNA or proteins; by reducing the release of viral genetic material inside host cells; by interfering with viral penetration of host cell membranes; and by interfering with attachment of virus to host cell membranes. Resistance to antiviral drugs can occur by a number of mechanisms. HIV infection is treated with a combination of antiviral drugs with different mechanisms of action. Infection with fungi can be superficial affecting skin and nails, or systemic affecting internal organs, particularly the lungs.

Ganciclovir is similar in mode of action. Adverse reactions can be severe so this drug is reserved for serious viral infections such as cytomegalovirus in immunocompromized patients.
