Many drugs are known to appear in breast milk and are listed in the BNF with advice about their use during breast feeding.

For details of injection techniques, Whatever the route of administration, a drug must reach its site of action. In order to do this, the drug will have to cross several cell membranes to reach the blood (unless it is injected intravenously). The three ways by which substances, including drugs, can cross cell membranes are simple diffusion, facilitated diffusion and active transport.

Drugs can also be given roaccutane 20mg injection. Methods of injection include subcutaneous, intramuscular, intravenous, intra-arterial, intra-articular, intraspinal and epidural. Drugs injected subcutaneously or intramuscularly have to diffuse between loose connective tissue or muscle fibres. The rate of absorption depends on the usual parameters for passage across cell membranes but also on the blood or lymphatic supply to a particular region.

Psoriasis is a chronic inflammatory skin disease with hyperproliferation of keratinocytes, which leads to thickening of the epidermis and typical silvery scales on the surface. Topical treatments include drugs that reduce cell division, such as calcipotriol, dithranol and coal tar, and keratolytics and emollients. Phototherapy using UVB and photochemotherapy using UVA plus an oral photosensitizing drug, psoralen, can be successful in severe resistant psoriasis, although relapse may occur.

If warfarin and aspirin are used simultaneously, both drugs appear in the plasma in higher than expected concentrations due to competition for plasma protein binding. This will increase the pharmacological activity of both drugs, but the action of warfarin is of most importance. Drug interaction is not always an adverse reaction.
