Match each type 2 diabetes mellitus medication to its most characteristic adverse effect or clinical contraindication.

  • MetforminAssociated with gastrointestinal distress and carries a risk of lactic acidosis in patients with severe chronic kidney disease.
  • EmpagliflozinAssociated with an increased risk of euglycemic diabetic ketoacidosis and vulvovaginal candidiasis.
  • SemaglutideMay cause significant nausea and vomiting, and is contraindicated in patients with a personal or family history of medullary thyroid carcinoma.
  • PioglitazoneCarries a risk of weight gain, fluid retention, and exacerbation of underlying heart failure.
  • GlimepirideCarries a high risk of hypoglycemia, particularly in older patients, and causes weight gain.

Cevap

Metformin matches with GI distress/lactic acidosis; Empagliflozin matches with euglycemic DKA/candidiasis; Semaglutide matches with nausea/medullary thyroid cancer risk; Pioglitazone matches with fluid retention/heart failure; Glimepiride matches with high risk of hypoglycemia.
Each antidiabetic medication class possesses a unique mechanism of action that corresponds to specific adverse effects. Metformin causes lactic acidosis in renal failure. SGLT2 inhibitors (empagliflozin) cause genitourinary infections and euglycemic DKA due to glycosuria. GLP-1 agonists (semaglutide) cause nausea and are contraindicated in medullary thyroid carcinoma. Thiazolidinediones (pioglitazone) cause fluid retention that worsens heart failure. Sulfonylureas (glimepiride) cause weight gain and hypoglycemia by stimulating insulin secretion.

Adım Adım Çözüm

1
Analyze the mechanism of action of Metformin.
Identify that it alters cellular metabolism and is renally cleared, predisposing to lactic acidosis in chronic kidney disease alongside its common GI side effects.
To correctly pair Metformin with its classic contraindication and adverse effect.
2
Evaluate SGLT2 inhibitors (Empagliflozin).
Identify that inducing glycosuria directly leads to genitourinary infections and alters ketone metabolism, leading to euglycemic DKA.
To differentiate SGLT2 inhibitor side effects from other drug classes.
3
Evaluate GLP-1 receptor agonists (Semaglutide).
Identify the delayed gastric emptying causing nausea and the specific black box warning regarding medullary thyroid carcinoma.
To isolate the unique endocrinologic contraindication of GLP-1 agonists.
4
Evaluate Thiazolidinediones (Pioglitazone).
Identify that PPAR-gamma activation causes sodium and fluid retention, worsening heart failure.
To pair TZDs with their cardiovascular contraindication.
5
Evaluate Sulfonylureas (Glimepiride).
Identify that insulin secretagogues inherently risk severe hypoglycemia, especially long-acting agents in the elderly.
To match the drug class directly causing unregulated insulin release with hypoglycemia.
