Summary
A 76-year-old man experienced a maculopapular rash after taking Finasteride for benign prostatic hyperplasia. This case suggests Finasteride can cause drug exanthema, a type of pharmacologic eruption.
Area of Science:
- Dermatology
- Pharmacology
Background:
- Benign prostatic hyperplasia (BPH) is common in older men.
- Finasteride is a 5α-reductase inhibitor used to treat BPH.
Observation:
- A 76-year-old male presented with a maculopapular rash on his trunk and extremities.
- The rash emerged two months after initiating Finasteride therapy.
Findings:
- Clinical suspicion pointed towards a drug exanthema caused by Finasteride.
- Clinical and histological findings confirmed a pharmacologic eruption attributed to Finasteride.
Implications:
- This case highlights the potential for Finasteride to induce cutaneous adverse drug reactions.
- Awareness of drug exanthema is crucial for clinicians managing patients on Finasteride.

01:27Allergic Drug Reactions
847
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

01:10Drug Excretion: Miscellaneous Routes
67
Drug excretion involves various organs, including the liver, intestines, skin, and eyes. In the case of drugs or toxins, they can be actively secreted into bile by transporters in the hepatocyte's canalicular membrane. These substances enter the GI tract during digestion and may be reabsorbed into the body from the intestine. This process, known as enterohepatic recycling, can significantly prolong the presence and effects of a substance in the body. To interrupt this cycle, specific...

01:23Nonlinear Pharmacokinetics: Dependence of Elimination Half-Life and Dose Clearance
157
The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.

Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

179
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
