    The concentration of a drug required to occupy 50 percent of its receptor sites is A the concentration required to produce the maximum physiological effect B directly proportional to the drug's affinity for its receptor C inversely proportional to the drug's affinity for its receptor D directly proportional to the drug's intrinsic efficacy E usually determined with the Schild equation 2. In the presence of a competitive antagonist the agonist log-concentration effect curve is A shifted to the right without a change in slope or maximum effect B shifted to the left without a change in slope or maximum effect C shifted to the right with a decreased slope and maximum effect D shifted to the left with a decreased slope and maximum effect E not shifted right or left but shows a decreased maximum effect 3. The magnitude of the response to a drug is related to the A total number of receptors for the drug B number of receptors occupied by the drug C number of vacant receptors in the tissue D number of spare receptors in the tissue E number of phosphorylated receptors in the tissue 4. The Schild equation shows that the concentration ratio of an agonist required to occupy the same number of receptors in the absence and presence of a competitive antagonist is determined by the A equilibrium constant of the agonist B affinity of the agonist for its receptor 33 C equilibrium constant of the antagonist D total number of available receptors E number of spare receptors in the tissue 5. A partial agonist is typically a drug that A has low affinity for its receptor B can only occupy a small fraction of its receptors C can only produce a submaximal response D requires high doses to produce a maximal response E increases the number of spare receptors 6. A type of drug that reduces the slope and maximum response of an agonist is A a non-competitive antagonist.

    This means that if you are prescribed these antibiotics, your doctor should be aware of all the medications you are currently taking and stop or reduce the dose of any medications that may be interacting. Some people have complained of side effects such as vomiting and diarrhoea with erythromycin. There has been a trend towards using those antibiotics that are better tolerated e.

    Nitroimidazoles Nitroimidazoles include metronidazole, tinidazole and nitrothiazoles. These antibiotics have a special nitro group and are active against bacteria that do not need any oxygen to survive — i. Anaerobes are commonly seen in infections such as bacterial vaginosis. Nitroimidazoles are changed to their active forms inside the bacteria. This produces free radicals and other compounds that are toxic to the cell, causing cell death.

    If you are one these medications, you should not take alcohol simultaneously — these drugs may prevent the breakdown and metabolism of alcohol in your body, causing an unpleasant reaction when mixed with alcohol. They have a broad spectrum of activity against gram-negative bacteria. They are well absorbed orally and are the only oral agents active against Pseudomonas aeruginosa.

    This is a type of bacteria that often affects patients who have an impaired immune system. Pseudomonas rarely causes infection in healthy people but it is a major cause of infections acquired in hospital. This group of antibiotics is commonly used to treat urinary and gastrointestinal intestines, stomach, bowel infections. Quinolones are antibiotics that should be reserved for treatment of resistant infections or where an oral drug with their spectrum of activity is required.

    Inappropriate use can lead to development of resistant bacteria, rendering bacteria that present a challenge for antibiotic treatment. Rifamycins These include rifampicin and rifabutin, which are antibiotics with a strong spectrum of activity against gram-positive organisms and mycobacteria.

    Mycobacteria are those bacteria that can cause diseases such as tuberculosis , infection of lymph nodes lymphadenitis and chest infections.

    There has been rapid development of resistance to these drugs when used alone, thus they are used in combination with other antibiotics. This group of antibiotics works by preventing bacteria from producing RNA and necessary proteins.

    Rifamycins are mainly used in tuberculosis and mycobacterium infections such as certain skin infections, in combination with other drugs.

    Rifamycins are antibiotics that can activate many enzymes. This results in many potential drug interactions, thus care must be taken when administering this medication with other drugs also metabolised by the same antibiotic system.

    These include blood thinning agents, the oral contraceptive pill , corticosteroids and oral drugs used in the treatment of diabetes.

    Sulphonamides and trimethoprim Sulfamethoxazole is the only commonly used sulphonamide, and is combined with the antibiotic trimethoprim to form the compound cotrimoxazole. It inhibits the formation of tetrahydrofolic acid, which is important for bacteria to form purines. Sulphonamides are broad spectrum antibiotics , active against many organisms. Due to the sulphonamide component in sulphonamides , some people may experience adverse effects or be allergic to this antibiotic. The main indication for trimethoprim is in the treatment of susceptible urinary tract infections.

    Cotrimoxazole should be restricted to situations where trimethoprim alone is ineffective or the infective organisms demonstrate resistance.

    Tetracyclines act by stopping bacteria from producing necessary proteins. They have a broad spectrum of activity, active against both gram-positive and gram-negative bacteria, protozoa and many anaerobes bacteria that can survive without oxygen.

    They are commonly used to treat chest infections acquired in the community, such as bronchitis , ear infections including otitis media and sinusitis. Tetracyclines may also be used to treat patients with genital tract infections, acne and as malaria prophylaxis. The preferred tetracycline in most situations is doxycycline, as it has a longer half life and can be taken once a day.

    Its use is limited by its side effects on the skin and the ears.

    If you are pregnant, tetracyclines should be used with caution during pregnancy. These antibiotics are also best avoided in children less than years old, due to potential effects on tooth development. Important issues regarding antibiotic use An important issue regarding antibiotic use is emerging resistance with some bacteria.

    Increasing resistance is demonstrated particularly in organisms such as methicillin resistant Staphylococcus aureus MRSA , Streptococcus pneumoniae and vancomycin-resistant enterococci VRE. They have demonstrated increasing resistance over the years and now even broader reserve antibiotics may not be effective against some highly resistant strains.

    It is important to know when an antibiotic is needed — most colds and flus are caused by viruses and do not require treatment with antibiotics.

    Unnecessary prescription of antibiotics is associated with unnecessary side effects, potential drug reactions and increased costs. Before taking antibiotics, you should tell your doctor if you have a history of hypersensitivity or allergic response to the drug that you are being prescribed.

    If you have any co-existing medical conditions or organ impairment e. Common side effects of antibiotics All antibiotics are associated with their own side effects.

    In general, antibiotics can affect the bacteria that live in your intestines, causing side effects such as nausea , vomiting and diarrhoea. The most common groups of antibiotics associated with hypersensitivity reactions are the beta lactam antibiotics. You should tell your doctor exactly what happens when you take an antibiotic, if you think you have an allergic reaction.

    True allergic reactions are supported by symptoms such as a drop in blood pressure, trouble breathing, rashes , swelling of the skin, lips and throat. How to tell if you are allergic or sensitive to antibiotics Antibiotic hypersensitivity is usually diagnosed on the basis of your history and appropriate investigations, including skin testing and oral challenges.


    Penicillin hypersensitivity Most beta lactam antibiotics that are associated with a hypersensitivity reaction commonly result in symptoms such as rash, fever , serum sickness-like reactions, and breakdown of cells.
