Anti-fungal drugs are medications used to treat fungal infections. Fungal infections can affect various parts of the body, including the skin, nails, hair, mucous membranes, and internal organs. Anti-fungal drugs work by targeting specific aspects of fungal cell structure or metabolism, inhibiting fungal growth and reproduction. Classification of Anti-fungal Drugs Anti-fungal drugs can be classified…
Anti-tubercular drugs are medications used in the treatment of tuberculosis (TB), a bacterial infection caused by Mycobacterium tuberculosis. These drugs work by inhibiting the growth and replication of the bacteria, thus helping to eliminate the infection from the body. Treatment typically involves a combination of several anti-tubercular drugs to prevent the development of drug resistance….
Sulphonamides, also known as sulfonamides, are a class of synthetic antimicrobial agents that inhibit the growth of bacteria by interfering with the synthesis of folate, a vital nutrient for the bacteria. They work by competitively inhibiting the enzyme dihydropteroate synthase, which is involved in the bacterial synthesis of folate. Without folate, bacteria are unable to…
Tetracyclines are a group of broad-spectrum antibiotics that belong to the class of polyketides. They are derived from Streptomyces bacteria and are characterized by a four-ring structure. Tetracyclines exert their antibacterial effects by inhibiting protein synthesis in bacteria, binding to the 30S ribosomal subunit, thereby preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex. Classification…

Drugs Used in Glaucoma: Glaucoma refers to a group of eye disorders characterized by damage to the optic nerve, often associated with increased intraocular pressure (IOP), which can lead to vision loss and blindness if left untreated. Management of glaucoma primarily involves the use of medications aimed at lowering IOP to prevent further damage to…
Myasthenia gravis (MG) is an autoimmune neuromuscular disorder characterized by muscle weakness and fatigue, typically resulting from antibodies targeting the acetylcholine receptors (AChR) at the neuromuscular junction. Treatment of MG primarily involves the use of medications aimed at improving neuromuscular transmission and reducing symptoms. Here’s a detailed note covering the definition, classification, pharmacological actions, dosage,…
Local anesthetic agents are medications used to induce reversible loss of sensation in a specific area of the body, without causing loss of consciousness. They are widely employed in various medical procedures to alleviate pain and discomfort. Here’s a detailed note covering their definition, classification, pharmacological actions, doses, indications, and contraindications: Definition: Local anaesthetics…
Neuromuscular blocking agents (NMBAs) and skeletal muscle relaxants (peripheral) are classes of drugs used to induce muscle relaxation in surgical and critical care settings. They act at the neuromuscular junction to inhibit or block the transmission of nerve impulses from motor neurons to skeletal muscle fibres, leading to paralysis or relaxation of skeletal muscles. These…
Sympatholytic, adrenergic blockers, or adrenergic antagonists Sympatholytic, also known as adrenergic blockers or adrenergic antagonists, are a class of drugs that inhibit the actions of the sympathetic nervous system by blocking adrenergic receptors. These receptors are targets for the neurotransmitters adrenaline (epinephrine) and noradrenaline (norepinephrine), and their activation leads to various physiological responses associated with…
