Are Expired Drugs Dangerous? Most drugs don't actually go "bad" in terms of causing harm, but they certainly may have lost potency and thus, may not have the desired effect after they expire. So, while not dangerous in the sense they won't cause immediate physical harm after taking them, it certainly is a danger to take a medication that doesn't have the desired effect. You certainly wouldn't want to take blood pressure or blood thinner medication that doesn't work as intended.
The same goes for antibiotics. You are putting yourself at unnecessary risk by taking an expired med. I do want to mention at the end of this section here, that there have been rare case reports of some expired drugs causing harm. One such example is a form of tetracycline available in the s, which was linked to kidney damage in those taking the expired drug. One of the main problems with expired drugs is that it can be difficult to tell if they have lost potency.
Some drugs, like aspirin, do show noticeable signs when they begin to break down. Expired aspirin, for example, begins to degrade into acetic acid, which has a distinct vinegar smell. Most drugs don't have noticeable signs of degradation however and the fact of the matter is if a drug is past its listed expiration date, you just don't know it is as potent as it once was. These steady-state levels were achieved after 3 days of drug administration.
Urine concentrations of both sulfamethoxazole and trimethoprim are considerably higher than are the concentrations in the blood. The average percentage of the dose recovered in urine from 0 to 72 hours after a single oral dose is Thirty percent of the total sulfonamide is excreted as free sulfamethoxazole, with the remaining as N4-acetylated metabolite.
Both sulfamethoxazole and trimethoprim distribute to sputum, vaginal fluid, and middle ear fluid; trimethoprim also distributes to bronchial secretions, and both pass the placental barrier and are excreted in human milk. Geriatric Pharmacokinetics The pharmacokinetics of sulfamethoxazole mg and trimethoprim mg were studied in 6 geriatric subjects mean age: Pharmacokinetic values for sulfamethoxazole in geriatric subjects were similar to those observed in young adult subjects.
Trimethoprim blocks the production of tetrahydrofolic acid from dihydrofolic acid by binding to and reversibly inhibiting the required enzyme, dihydrofolate reductase.
Thus, this combination blocks two consecutive steps in the biosynthesis of nucleic acids and proteins essential to many bacteria.
In vitro studies have shown that bacterial resistance develops more slowly with this combination than with either sulfamethoxazole or trimethoprim alone. In vitro serial dilution tests have shown that the spectrum of antibacterial activity of sulfamethoxazole and trimethoprim includes the common urinary tract pathogens with the exception of Pseudomonas aeruginosa.
The following organisms are usually susceptible: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis and indole-positive Proteus species including Proteus vulgaris. The usual spectrum of antimicrobial activity of sulfamethoxazole and trimethoprim includes the following bacterial pathogens isolated from middle ear exudate and from bronchial secretions: Haemophilus influenzae, including ampicillin-resistant strains, and Streptococcus pneumoniae.
Shigella flexneri and Shigella sonnei are usually susceptible. The usual spectrum also includes enterotoxigenic strains of Escherichia coli ETEC causing bacterial gastroenteritis. Susceptibility Testing: The recommended quantitative disc susceptibility method may be used for estimating the susceptibility of bacteria to sulfamethoxazole and trimethoprim. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy.
In the absence of such data, local epidemiology and susceptibility patterns may contribute to empiric selection of therapy. Urinary Tract Infections For the treatment of urinary tract infections due to susceptible strains of the following organisms: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis and Proteus vulgaris. It is recommended that initial episodes of uncomplicated urinary tract infections be treated with a single effective antibacterial agent rather than the combination.
Acute Otitis Media For the treatment of acute otitis media in pediatric patients due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when in the judgment of the physician sulfamethoxazole and trimethoprim offers some advantage over the use of other antimicrobial agents. To date, there are limited data on the safety of repeated use of sulfamethoxazole and trimethoprim in pediatric patients under two years of age.
Sulfamethoxazole and trimethoprim is not indicated for prophylactic or prolonged administration in otitis media at any age. Acute Exacerbations of Chronic Bronchitis in Adults For the treatment of acute exacerbations of chronic bronchitis due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when in the judgment of the physician sulfamethoxazole and trimethoprim offers some advantage over the use of a single antimicrobial agent.
Shigellosis For the treatment of enteritis caused by susceptible strains of Shigella flexneri and Shigella sonnei when antibacterial therapy is indicated. Pneumocystis Carinii Pneumonia For the treatment of documented Pneumocystis carinii pneumonia and for prophylaxis against Pneumocystis carinii pneumonia in individuals who are immunosuppressed and considered to be at an increased risk of developing Pneumocystis carinii pneumonia. Sulfamethoxazole and trimethoprim is also contraindicated in pregnant patients and nursing mothers, because sulfonamides pass the placenta and are excreted in the milk and may cause kernicterus.
Sulfamethoxazole and trimethoprim is contraindicated in pediatric patients less than 2 months of age. Sulfamethoxazole and trimethoprim is also contraindicated in patients with marked hepatic damage or with severe renal insufficiency when renal function status cannot be monitored.
Clinical signs, such as rash, sore throat, fever, arthralgia, pallor, purpura or jaundice may be early indications of serious reactions. Cough, shortness of breath, and pulmonary infiltrates are hypersensitivity reactions of the respiratory tract that have been reported in association with sulfonamide treatment.
In an established infection, they will not eradicate the streptococcus and, therefore, will not prevent sequelae such as rheumatic fever. Clostridium difficile associated diarrhea CDAD has been reported with use of nearly all antibacterial agents, including sulfamethoxazole and trimethoprim, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C.
Hypertoxin producing strains of C. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. Sulfamethoxazole and trimethoprim should be given with caution to patients with impaired renal or hepatic function, to those with possible folate deficiency e.
In glucosephosphate dehydrogenase deficient individuals, hemolysis may occur. This reaction is frequently dose-related. Cases of hypoglycemia in non-diabetic patients treated with sulfamethoxazole and trimethoprim are seen rarely, usually occurring after a few days of therapy. Patients with renal dysfunction, liver disease, malnutrition or those receiving high doses of sulfamethoxazole and trimethoprim are particularly at risk.
Hematological changes indicative of folic acid deficiency may occur in elderly patients or in patients with preexisting folic acid deficiency or kidney failure. These effects are reversible by folinic acid therapy. Folate is an essential metabolite for bacterial growth and replication because it is used in DNA synthesis , primarily at thymidylate and purine biosynthesis, and amino acids synthesis, including serine, glycine and methionine.
Since it inhibits bacterial growth, sulfamethoxazole is considered a bacteriostatic antibiotic. Humans do not synthesize folate, and must acquire it through diet. It is rapidly absorbed when it is orally administered. Its Tmax or time to reach maximum drug concentration in plasma occurs 1 to 4 hours after oral administration.

An L-subtype voltage-gated calcium channel bottom right is closed at RMP. One of these properties is its ability to life like amiloride in the distal portion of the renal tubule. Traces are before leftduring upper right superfusion with 2. Properties that are critically important for bactrim neuronal function, such as threshold, refractory period, and action potential patterning, are all affected by the types half sodium channels that are deployed within a given bactrim.
Figure 19 Plant Sodium Channel Openers We are now ready to discuss plant sodium channel openers in more detail, again focusing on half cardiovascular actions.
Each domain spans life plasma membrane six times S1 — S6. DOI: Neuropathol Appl Neurobiol ;
These channels all share a common overall structural motif The voltage-dependent interaction results in IC50 values for anesthetic suppression of sodium channels that are close to clinical concentrations at potentials near the resting membrane potential.
The alpha subunits are members of a large gene family containing the voltage-gated sodium, potassium, and calcium channels. Sodium channel alpha subunits form a gene subfamily with at least eleven members.
Mutations in sodium channel alpha subunit genes have been linked to paroxysmal disorders such as epilepsy, long QT syndrome LQT , and hyperkalemic periodic paralysis in humans, and motor endplate disease and cerebellar ataxia in mice. Three genes encode the sodium channel beta subunits with at least one alternative splice product. Unlike the pore-forming alpha subunits, the sodium channel beta subunits are not structurally related to beta subunits of calcium and potassium channels.
Sodium channel beta subunits are multifunctional. They modulate channel gating and regulate the level of channel expression at the plasma membrane. We have shown that beta subunits also function as cell adhesion molecules CAMs in terms of interaction with extracellular matrix molecules, regulation of cell migration, cellular aggregation, and interaction with the cytoskeleton.
Alpha subunits: The alpha subunits are made up of four transmembrane domains, with each domain consisting of six segments. The voltage sensory component is on the fourth segment of each alpha domain. Interestingly, the beta subunits are actually a part of the Ig superfamily of cell adhesion molecules due to their large, extracellular V-set immunoglobulin Ig domain.
Pathophysiology Research has identified over missense mutations that affect seven different voltage-gated sodium channels that cause excitability disorders or channelopathies. While these disorders are rare, they are an example of how proteins altered by genetic variability and mutations can profoundly affect the functioning of voltage-gated sodium channels.
Since mutated voltage-gated sodium channels are one of the primary causes for epilepsy, it makes sense that many first-line drugs for epilepsy are from the sodium channel blocker class. The dysfunction can be genetic or acquired, including secondary to toxins. In particular, toxins from marine animals have a preference for blocking voltage-gated sodium channels, resulting in sensory abnormalities because of dysfunction of sensory neurons and muscle weakness from the pathology of the motor neurons and muscle cells.
One such toxin is the tetrodotoxin from the Tetraodontidae family, more commonly referred to as pufferfish that store the toxin in high concentrations in its liver. The toxin gets absorbed and travels systemically, where it can bind to sodium channels in a variety of tissues.
The prevention of contractility of both cardiac and respiratory myocytes can lead to respiratory arrest and cardiac arrest, leading to possible death. Voltage-gated sodium channels are the target of multiple pharmacological compounds, including anesthetics like lidocaine, antiepileptics like phenytoin and lamotrigine, and antiarrhythmics like flecainide and mexiletine. The prevention of nerve conduction is the mechanism of drugs like lidocaine blocks the potentiation of pain signals, while antiepileptics such as phenytoin and lamotrigine lower the seizure threshold by similarly reducing neuron excitability.
The prevention of action potentials, particularly on the presynaptic neuron, prevents downstream signal transmission by inhibiting the release of neurotransmitters at the synaptic cleft. Due to the extensive distribution of sodium channels in a wide array of organ systems, care is necessary when prescribing or administering sodium channel blockers. Lidocaine, for instance, is a potent local anesthetic used routinely for procedures and laceration repairs but does carry the risk for systemic release.
High doses of lidocaine released into systemic circulation can be toxic to both the CNS and cardiovascular system causing seizures, AV heart block, arrhythmias, and more.
