They don’t work in treating viral infections which accounts for the vast majority of coughs purchase 200 mg urispas free shipping muscle relaxant 751, colds order urispas 200 mg with visa muscle relaxant and nsaid, flu’s, earache, sinus, and chest infections which people suffer from every winter. While there are some specific antiviral medications most viruses do not have a specific drug to treat infections caused by them. There is no one antibiotic that works in every situation and giving the wrong antibiotic can be worse (long-term) than not giving one at all. Each organism has one or two antibiotics that are specific for that organism and that is the antibiotic which should be used. The Bacteria: A basic understanding of how bugs (read bacteria) cause infections is required to appropriately use antibiotics. There are hundreds of millions of different species of bacteria; most do not cause illness in man. There are four main classes of bacteria - Gram-positive (+ ve) - Gram-negative (- ve) - Anaerobes - Others Gram-positive bacteria stain blue and gram-negative bacteria stain pink when subjected to a gram staining test. They are further subdivided by their shape (cocci = round, bacilli = oval) and if they form aggregates or not. Causes boils, abscesses, impetigo, wound infections, bone infections, pneumonia (uncommonly), food poisoning, and septicaemia. Generally very sensitive to Flucloxacillin as first choice drug, and Augmentin, and the cephalosporins. Strep pneumoniae causes pneumonia, ear infections, sinusitis, meningitis, septic arthritis, and bone infections. Strep pyogenes causes sore throats, impetigo, scarlet fever, cellulitis, septicaemia, and necrotising fasciitis. Streps are usually very sensitive to penicillins, cephalosporins, and the quinolones. Gram-Negative Bacteria (Gram -ve) * Neisseria meningitidis: Gram-negative cocci in pairs. Sensitive to penicillins, cephalosporins, quinolones, Co-trimoxazole, and tetracyclines. Sensitive to high dose amoxicillin (single dose), Augmentin, and also cephalosporins, and quinolones. Sensitive to Augmentin, cephalosporins, quinolones, Co-trimoxazole, and tetracyclines. Causes urinary infections, severe gastroenteritis, peritonitis (from bowel injury), and septicaemia. Coli is becoming increasingly resistant to both (although in many areas they work fine – that is why it is important to understand local resistant patterns which can be obtained from the microbiology labs at your local hospital). We recommend Co-trimoxazole as a first choice – especially for urinary tract infections. Commonly causes infections following injury to the bowel, or wound contamination, causes abscess formation. Treated first choice with metronidazole or second with chloramphenicol or Augmentin. Chloramphenicol is moderately high risk with high doses (>4gm/day) causing bone marrow suppression which rarely can be fatal – but it is cheap, readily available, and complications are rare. Antibiotics Penicillins - These act by preventing replicating bacteria from producing a cell wall. A number of bacteria produce an enzyme which inactivates the penicillins ( B- lactamase). A number of varieties: * Benzylpenicillin (Penicillin G Benzathine): Injectable preparation. Antibiotic of choice against severe Strep pneumoniae and Neisseria sp infections such as chest infections, meningitis, and cellulitis. Usually used only for the treatment of sore throats (strep throats); in other infections largely replaced by amoxicillin which is better absorbed. Beta-lactamase production is a method by which the bacteria try and protect themselves against an antibiotic – it is a bacterial enzyme which breaks down the main active ingredient of penicillin antibiotics. Overcoming this resistance makes this combination my ideal survival antibiotic, with good gram-positive, negative, and - 42 - Survival and Austere Medicine: An Introduction anaerobic cover. Other antibiotics may be better for specific infections but this is the best all purpose one.

Overdose may produce transient or lasting efects buy urispas 200mg otc muscle relaxant herniated disc, or death purchase 200mg urispas mastercard muscle relaxant sciatica; the lethal dose of a particular drug varies with the individual and with circumstances. Industry terminology categorizes drugs as ethical drugs, available only on prescription, and over-the-counter or proprietary drugs, advertised to the consumer and sold without prescription. The list of drugs requiring prescription varies considerably from country to country; most psychoactive pharmaceuticals are only available by prescription in industrialized countries. It also covers allied felds such as toxicology and posology (see defnition below). Knowledge of the dose of commonly used drugs is essential for acquiring confdence in prescribing. Receptors are named afer the type of neurotransmitter that they preferentially bind to, for instance, dopamine receptors. This process determines the rate at which a substance is absorbed into the bloodstream. Tablets or capsules are swallowed and substances are ingested and broken down into metabolites through the digestive system. These forms pass the intestines and only once dissolved are they able to cross the mucosal membranes in order to reach the bloodstream, pass the blood brain barrier and produce efects. Given the length of time needed for these processes to occur, substances administered orally have a slower onset but have a longer duration of efects. There is a dose-dependent mechanism of some drugs, in which a higher dose results in a longer duration of efects, thus making it difcult to quantify precisely. Buccal refers to the placement of a substance into the mouth until it is dissolved. Sublingual refers to the placement of a substance underneath the tongue until it is dissolved. Intramuscular is an injection through the muscle, which is the slowest method of drug delivery throughout the body. Onset is almost immediate, as the drug particles are able to cross the mucosal membranes within the nose and close to the brain. Suppositories are capsules that contain the substance powder, which can be easily administered rectally. The onset of efects is delayed as the capsule may take time to dissolve causing a delay of the absorption of the substance into the bloodstream. Major classes of sedatives/ hypnotics include the benzodiazepines and barbiturates. Other drugs have stimulant actions which are not their primary efect but which may be manifest in high doses or afer chronic use. The term can be used to diferentiate between these drugs and the sedative/hypnotics: tranquillizers have a quieting or damping efect on psychomotor processes without—except at high doses—interference with consciousness or thinking.

Nutt, “Amphetamine, past and present— a pharmacological and clinical perspective”. In a workplace, this harmful efect potentially extends to the health and safety of colleagues, co-workers, customers and to the workplace in general. The use of alcohol and other drugs, even in small amounts, can impair our performance, judgement, coordination, concentration and alertness. On a worksite, the use of alcohol and other drugs may result in: mistakes, accidents and injuries damage to workplace equipment, causing subsequent injuries a deterioration in workplace relationships increased sickness-related absenteeism lateness and lost time a decrease in productivity a decrease in staf morale. The use of alcohol and other drugs can also lead to increased risks or unpredictable behaviour when combined.

Case While working in a hospital, a fourth-year resident is con- tacted by a community pharmacist who wants to clarify the dose of narcotic prescribed for a physician colleague and friend. The resident is taken aback, as they have never written such a prescription for this person. The pharmacist confrms that the resident’s name and signature are on the prescription and that this is the same person who provided prescriptions for the physician in the past when flled at this pharmacy.
