Introduction Latanoprost is a prostaglandin F2α (PGF2α) analog used as a first-line agent in the management of open-angle glaucoma and ocular hypertension. It effectively lowers intraocular pressure (IOP) by increasing aqueous humor outflow, thereby preventing optic nerve damage and vision loss. Mechanism of Action (Step-wise) Pharmacokinetics Clinical Uses Adverse Effects Comparative Analysis Feature Latanoprost Timolol … Read more
Introduction β-Lactamase inhibitors are a class of drugs used in combination with β-lactam antibiotics to overcome bacterial resistance. Many bacteria produce β-lactamase enzymes that hydrolyze the β-lactam ring, rendering antibiotics like penicillins and cephalosporins ineffective. β-Lactamase inhibitors protect these antibiotics by inhibiting the enzyme, thereby restoring their antibacterial activity. Mechanism of Action (Step-wise) Pharmacokinetics Clinical … Read more
Introduction Labetalol is a mixed adrenergic receptor antagonist with both α1- and β-adrenergic blocking properties. It is widely used in the management of hypertension, including hypertensive emergencies and pregnancy-induced hypertension. Its unique dual action allows it to reduce blood pressure without significant reflex tachycardia. Mechanism of Action (Step-wise) Pharmacokinetics Clinical Uses Adverse Effects Comparative Analysis … Read more
Introduction Ketorolac is a potent nonsteroidal anti-inflammatory drug (NSAID) primarily used for short-term management of moderate to severe pain, especially postoperative pain. It is often considered an alternative to opioids due to its strong analgesic effect without causing respiratory depression. Ketorolac belongs to the acetic acid class of NSAIDs and is known for its significant … Read more
Introduction Levetiracetam (brand name: Keppra) is a broad-spectrum antiepileptic drug used in the management of partial seizures, myoclonic seizures, and generalized tonic-clonic seizures. It is known for its unique mechanism of action, favorable safety profile, and minimal drug interactions, making it widely used in both adults and pediatric patients. Mechanism of Action (Step-wise) Pharmacokinetics Clinical … Read more
Introduction Ivabradine is a selective heart rate–reducing agent primarily used in the management of chronic stable angina and heart failure with reduced ejection fraction (HFrEF). Unlike beta-blockers, it reduces heart rate without affecting myocardial contractility or blood pressure significantly. Its action is highly specific to the sinoatrial (SA) node. Mechanism of Action (Step-wise) Pharmacokinetics Clinical … Read more
Introduction Isotretinoin is an oral retinoid (13-cis-retinoic acid) primarily used in the treatment of severe nodulocystic acne and acne resistant to conventional therapy. It is one of the most effective anti-acne agents because it targets multiple pathogenic factors involved in acne development, including sebum production, follicular keratinization, bacterial proliferation, and inflammation. Mechanism of Action (Step-wise) … Read more
Introduction Isoprenaline (isoproterenol) is a non-selective β-adrenergic agonist that stimulates both β1 and β2 receptors. It is used in conditions such as bradycardia, heart block, and occasionally in asthma. Due to its potent cardiac and bronchodilatory effects, it plays an important role in emergency and specific clinical settings. Mechanism of Action (Step-wise) Pharmacokinetics Clinical Uses … Read more
Introduction Irinotecan is a semi-synthetic camptothecin derivative used as an antineoplastic agent, primarily in the treatment of colorectal cancer and other solid tumors. It is a prodrug that requires metabolic activation to exert its cytotoxic effects. Irinotecan interferes with DNA replication in rapidly dividing cancer cells, leading to cell death. Mechanism of Action (Step-wise) Pharmacokinetics … Read more
Introduction Ipratropium bromide is a short-acting anticholinergic (antimuscarinic) bronchodilator primarily used in the management of chronic obstructive pulmonary disease (COPD) and, in some cases, asthma. It is a quaternary ammonium compound derived from atropine, designed for inhalational use with minimal systemic absorption. Its main action is to reduce bronchoconstriction mediated by the parasympathetic nervous system. … Read more
