These nociceptors are sensitive to the effects of potentially damaging mechanical, thermal and chemical stimuli. When cells are damaged they release a variety of chemical mediators, which can activate or sensitize nociceptors to other chemicals. This explains acute pain. Chronic pain is more difficult to explain, especially if it goes on beyond the initial tissue damage. Chronic pain is thought to be associated with changes to the normal physiological pain pathway.

Certainly, the genesis of cancer involves many factors working together. Characteristics of cancer include uncontrolled cell division with excessive growth of undifferentiated cells. Cancer cells invade surrounding tissues, whereas normal cells do not survive outside their normal boundaries. Cancer cells may travel to distant sites in the body via the blood and lymph to form secondary tumours that are called metastases. As cells repeatedly divide a mass forms known as a tumour, which needs a blood supply.

These fungi are commonly occurring in the environment and they thrive in tissues that contain keratin. Such fungal infections of the skin are known as tinea: Tinea pedis is infection of the foot (athletes foot); tinea corporis is infection on the body and tinea capitis is infection of the scalp. Fungal infection of the nails is known as tinea unguium or onychomycosis. Superficial fungal infections can usually be treated with topical preparations, but systemic antifungal drugs can be necessary for nail and scalp infections, or if skin infection is extensive and unresponsive to topical therapy. There are many topical treatments available of varying efficacy.

She has been told that she will have a premedication and asks you what this is for. What can you tell her. Can you give some examples of drugs used for premedication. Apart from the anaesthetic itself, what other types of drugs might be used during the operation.

Chemical names can be complicated and difficult to remember and are not used in this book. A generic yellow diazepam 5mg is a drugs official name and the majority of drugs in this book are referred to by their generic names. The proprietary name is the name given to a drug by the manufacturing company. As the same drug can be manufactured by several different companies, a drug can have multiple proprietary names and this can be confusing.

Excipients with known effect. Antenex contains lactose monohydrate and traces of galactose and sulfites. For the full list of excipients, see Section 6. Mechanism of action. Diazepam is a member of the group of benzodiazepines and exhibits anxiolytic, sedative, muscle relaxant and anticonvulsant effects. This is presumed to be the result of facilitating the action in the brain of gamma-aminobutyric acid, a naturally occurring inhibitory transmitter.

Clinical trials. No data available. After oral administration, diazepam is rapidly and completely absorbed from the gastrointestinal tract, with peak plasma concentrations occurring 30 to 90 minutes after ingestion. Diazepam and its metabolites cross the blood brain and placental barriers and are also found in breast milk. The elimination half-life is 90 hours at age 80 and increased two to threefold in patients with cirrhosis.

Pharmacokinetics in special population. The elimination half-life may be prolonged in the newborn, the elderly and patients with hepatic or renal disease and it should be noted that the plasma concentration may take correspondingly longer to reach steady state. Limited data from a number of studies have provided weak evidence of a genotoxic potential.

The carcinogenic potential of oral diazepam has been studied in several rodent species. Management of anxiety disorders or for the short-term relief of the symptoms of anxiety. In acute alcohol withdrawal, Antenex may be useful in the symptomatic relief of acute agitation, tremor, impending or acute delirium tremens and hallucinosis. It can also be used to combat spasticity due to upper motor neuron lesions such as cerebral palsy and paraplegia, as well as in athetosis and stiff man syndrome.

Antenex is contraindicated in: patients with known hypersensitivity to benzodiazepines; patients with chronic obstructive airways disease with incipient respiratory failure; patients with severe respiratory insufficiency; patients with severe hepatic insufficiency; patients with sleep apnoea syndrome; patients with myasthenia gravis; patients with dependence on CNS depressants other than alcohol; patients with alcohol dependence unless being treated for acute alcohol withdrawal.

Benzodiazepines are not recommended for the primary treatment of psychotic illness. Benzodiazepines should not be used alone to treat depression or anxiety associated with depression as suicide may occur in such patients. Patients should be advised that their tolerance for alcohol and other CNS depressants will be diminished and that these medications should either be eliminated or given in reduced dosage in the presence of Antenex. An individualised withdrawal timetable needs to be planned for each patient in whom dependence is known or suspected.

Periods from four weeks to four months have been suggested. As with other benzodiazepines, when treatment is suddenly withdrawn, a temporary increase of sleep disturbance can occur after use of Antenex see Section 4. In general, benzodiazepines should be prescribed for short periods only e. Continuous long-term use of Antenex is not recommended. There is evidence that tolerance develops to the sedative effects of benzodiazepines.

Although hypotension has occurred only rarely, Antenex should be administered with caution to patients in whom a drop in blood pressure might lead to cardiac or cerebral complications. This is particularly important in elderly patients.

See Figure transmission. The events that take place at a synapse, that is synthesis of neurotransmitter, storage in vesicles, release, interaction with receptors and eventual inactivation provide targets for drug action. Inactivation of a neurotransmitter can be by re-uptake into the neuron it was released from, or by the action of enzymes in the synaptic cleft.

The nervous system in helminths has important differences from that of humans and these differences form the basis of the selective toxicity of most drugs used to treat such infections. For example, nematode muscles have both excitatory and inhibitory neuromuscular junctions. The neurotransmitters are acetylcholine and gamma-aminobutyric acid, respectively. Anthelmintics either act locally to expel worms from the gastrointestinal tract, or systemically to eradicate forms that have invaded tissues and organs.

The yellow diazepam 5mg product then brings about the action of the original drug. Methyldopa can be used again as an example here. It is a false substrate for the enzyme that normally converts dopa into dopamine. Some drugs need conversion by an enzyme from an inactive pro-drug into an active form before they can be of therapeutic use.

Lidocaine is probably the most commonly used local anaesthetic. Qualified, registered podiatrists are allowed to access and administer lidocaine, bupivacaine, prilocaine, mepivacaine, levobupivacaine and ropivacaine. Analgesia can be achieved by peripherally acting and centrally acting analgesics.

Many advances in treatment and understanding of the molecular biology of cancer have been made since the mid- curable and there have also been improvements in treatment of ongoing disease and in palliative care. The three main approaches to treatment are surgery, radiotherapy and chemotherapy. The way in which they are combined depends on the type of cancer and its stage at diagnosis. Only a few cancers are treated with chemotherapy alone. New approaches to treatment now include gene therapy, immunotherapy, stimulation of bone marrow, induction of differentiation in cancer cells and inhibition of angiogenesis in addition to the more standard chemotherapy.

There are two general types of metabolic reactions, which are known as Phase Phase on its chemical nature, it is possible for a drug to be metabolized by either type of reaction only. See Figure Phase reactions to a more water-soluble metabolite, which is more likely to be excreted by the kidney or go on to Phase reaction, which involves the addition of oxygen to the drug molecule. In the liver, oxidation reactions are catalysed by a group of enzymes known as the microsomal mixed function oxidase system or the cytochrome P Oxidative reactions take place in many other tissues as well. of hydrogen to the drug molecule. Enzymes capable of catalysing reduction reactions are found in many body tissues, including the liver and in the intestinal bacteria.
