A drug of last resort (DoLR), also known as a heroic dose, [1] is a pharmaceutical drug which is tried after all other drug options have failed to produce an adequate response in the patient. Drug resistance , such as antimicrobial resistance or antineoplastic resistance , may make the first-line drug ineffective, especially in case of ...
It has more fatty acid chains than vancomycin and is considered to be 50 to 100 times more lipophilic. Teicoplanin also has an increased half-life compared to vancomycin, as well as having better tissue penetration. It can be two to four times more active than vancomycin, but it does depend upon the organism.
May be more narrow-spectrum than vancomycin, resulting in less bowel microbiota alteration. [9] Nausea (11%), vomiting, and abdominal pain. [10] Bactericidal in susceptible organisms such as C. difficile by inhibiting RNA polymerase, thereby inhibiting protein synthesis. [10] Monobactams; Aztreonam: Azactam: Gram-negative bacteria
Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. [9] [10] Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA).
Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
Common side effects include nausea, vomiting, rash, and diarrhea. [2] Severe allergic reactions and Clostridioides difficile infection may occasionally occur. [2] Its use in pregnancy is not recommended. [2] [19] It appears to be safe for use during breastfeeding as long as the baby is healthy. [19]
Clindamycin alone has been shown to be efficacious in the treatment of acne, [24] toxic shock syndrome [25] and malaria, [26] and to decrease the risk of premature births in women with bacterial vaginosis. [27] Lincosamide antibiotics may also be useful in the treatment of methicillin-resistant S. aureus. [28]
The usual dose by mouth is one capsule of 250 mg 4 times a day in adults and half the adult dose as a syrup for children under the age of 10 years but over 2. [4] For children below the age of 2 years, the oral dose is a quarter of the adult oral dose. [3] Ampicillin/flucloxacillin is taken orally about half an hour before food. [5]
