Aminoglycosides High doses of parenteral penicillin can inactivate aminoglycosides. In patients receiving low doses of aminoglycosides because of reduced renal function this can be clinically important. Parenteral administration of these drugs in neonatal dosages does not seem to produce relevant inactivation, and so temporal separation of the infusions is not required. Piperacillin protected against aminoglycoside nephrotoxicity without reducing its blood concentration; this was possibly a protective effect of co-administered mineral salts. Ciclosporin …

Contents Drug formulations Embolictoxic reactions to penicillin depot formulations were first described in patients with syphilis. The symptoms include fear of death, confusion, acoustic and visual hallucinations, and possibly palpitation, tachycardia, and cyanosis. Generalized seizures or twitching of the limbs have been observed in children and adults. As a rule, the symptoms abate and disappear within several minutes to an hour. They rarely persist for up to 24 hours. If a cardiovascular reaction with a fall in blood pressure occurs simultaneously with typical symptoms, a combination with anaphylactic shock must be considered. Such reactions have been called “pseudo-anaphylactic reactions” or “acute non-allergic reactions”, “panic attack syndrome,” and “acute psychotic reactions”. In …

Acute severe dyspnea with cyanosis has also been observed without symptoms of bronchial obstruction or pulmonary edema. Specific mechanisms for such cases have yet to be identified. Allergic pneumonitis and transient eosinophilic pulmonary infiltrate (Loeffler’s syndrome) are rare. These syndromes have also been observed with penicillin hypersensitivity. In one case, an alveolar allergic reaction, probably due to ampicillin, showed features of an adult respiratory distress syndrome. Nervous system High doses of penicillins, …

However, anaphylactic shock is less common after oral than parenteral administration. In one study the incidence of anaphylactic shock was 0.04% of all patients treated with penicillin. It is also low in patients receiving long-term benzathine penicillin (1.2 million units every 4 weeks). Four episodes of anaphylaxis occurred in 0.012% of injections (1.2 reactions to 10 000 injections). Anaphylactic shock resulting in death occurred in 0.002% of all patients treated with penicillin and in 0.003% of those treated with benzathine penicillin. In …
[ Continue Reading... ]Skin reactions are the commonest adverse effects of therapeutically administered penicillins. Penicillin-contaminated milk or meat can cause itching or generalized skin reactions or even anaphylaxis. Incidence The overall annual incidence of severe erythema multi-forme (toxic epidermal necrolysis and Stevens-Johnson syndrome) is about one case per million, antibiotics being involved in 30-40%. The clinical differentiation between these syndromes can be difficult. Allergic contact dermatitis is usually caused by topical drugs, but is also seen in connection with ingestion, injection, or inhalation. The increased frequency of contact eczema due to cloxacillin and bacampicillin may be because they are intensely irritant and …
[ Continue Reading... ]Penicillin-induced hepatotoxicity may not be as uncommon as has been thought. There have been three reviews. The first was a comparison of the assessment of drug-induced liver injury obtained by two different methods, the Council for International Organizations of Medical Sciences (CIOMS) scale and the Maria & Victorino (M&V) clinical scale. Three independent experts evaluated 215 cases of hepatotoxicity reported using a structured reporting form. There was absolute agreement between the two scales in 18% of cases, but there was no agreement in cases of fulminant hepatitis or death. The authors concluded that the CIOMS instrument is more likely …

Information on this association has come predominantly from case series and hospital surveys (38^. Some evidence can be extracted from population-based studies that have focused on aplastic anemia and agranulocytosis and their association with many drugs, including antimicrobial drugs. The incidence rates of blood dyscrasias in the general population have been estimated in a cohort study with a nested case-control analysis, using data from a General …

It was introduced in 1948 and grew in popularity because of its high antimicrobial activity against a wide range of Gram-positive and Gram-negative bacteria, Rickettsiae, Chlamydia, and Mycoplasma species. It is particularly useful in infections caused by Salmonella typhi and Haemophilus influenzae. It is mainly bacteriostatic. It readily crosses tissue barriers and diffuses rapidly into nearly all tissues and body fluids. The main route of elimination …

The syndrome of pseudotumor cerebri consists of symptoms and signs of raised intracranial pressure in the absence of neuroimaging or cerebrospinal fluid abnormalities. Most cases are idiopathic, but several drugs have been implicated as causative or contributory. The first description of minocycline-related pseudotumor cerebri was published in 1978. Further data have been published concerning 12 patients who developed pseudotumor cerebri after taking standard doses of minocycline for acne vulgaris. Nine developed symptoms within 8 weeks of …
