Combining corticosteroids with other topical treatment is effective in some cases. These drugs are reserved for patients with the most severe forms of psoriasis that do not respond to, or cannot tolerate, topical or phototherapy. Use of systemic antipsoriatic drugs is generally under supervision of a dermatologist in a hospital setting. Methotrexate is the most common treatment for resistant and widespread psoriasis. Its main actions are cytotoxic and immunosuppressant. Methotrexate inhibits an enzyme (dihydrofolate reductase) necessary for the synthesis of purine nucleotides (adenine and guanine), which are components of DNA. This results in a reduction in DNA synthesis and particularly affects rapidly dividing cells.

DNA is a large molecule arranged in two long strands coiled around each other to form the double helix. Each strand is composed of millions of nucleotides. A nucleotide has three components: a base, which is an organic molecule containing nitrogen; a five-carbon sugar called deoxyribose; and a phosphate group. Nucleotides are joined to each other by bonds between the sugar of one nucleotide and the phosphate group of the next to form polynucleotides. There are four different bases in DNA: adenine, guanine, cytosine and thymine.

Trimethoprim inhibits another enzyme, dihydrofolate reductase, in the same folic acid metabolic pathway. Folic acid is converted into folate, which then has to be converted into an activated form by dihydrofolate reductase. In this way, trimethoprim interferes with the conversion of folate into its activated form, which is a cofactor in the synthesis of bacterial DNA. Dihydrofolate reductase also occurs in host cells, but it is less sensitive to trimethoprim. Trimethoprim is used to treat urinary tract infections.

Stomach acid and enzymes can destroy some drugs and they have to be protected by an enteric coat so they pass unharmed into the small intestine. Semi-digested and liquidized food passes gradually from the stomach into the duodenum, the first part of the small intestine. The small intestine is the most important part of the digestive system for digestion because it produces many enzymes and is highly adapted for absorption of nutrients. It has a large overall surface area because of its length and because its inner lining is bought phentermine 37.5 mg without prescription into villi.

However, the organism appears to have characteristics of both protozoa and fungi so its classification is currently uncertain. This organism has been renamed as Pneumocystis jiroveci and reclassified as a fungus by some authorities.

A drug metabolite may have a new and completely different pharmacological activity, or it may be as active as or more active than the original drug. Some drugs have to be metabolized in order to become active. Prodrugs are drugs that have been designed to remain inactive until they have been metabolized by the body. They may be formulated in this way because the active drug is difficult to administer, whereas the inactive prodrug does not cause the same complications, or because the active drug is not absorbed or distributed to its intended site of action easily. Most tissues in the body have the enzymes capable of metabolizing a variety of substances.

Adverse reactions can be severe so this drug is reserved for serious viral infections such as cytomegalovirus in immunocompromized patients. Adverse effects include bone marrow suppression, liver and kidney toxicity and central nervous system damage. Some RNA viruses are known as retroviruses. These viruses use an enzyme called reverse transcriptase to copy viral RNA to produce viral DNA. The viral DNA is then incorporated into the buy phentermine 37.5 mg without prescription cells DNA where it can lie dormant before being used as a template for the production of more viral RNA. Drugs have been developed to inhibit reverse transcriptase and are used particularly to treat HIV.
