Anthelminthic Agents01:15

Anthelminthic Agents

40
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...

Antiasthma Drugs: Muscarinic Receptor Antagonists01:20

Antiasthma Drugs: Muscarinic Receptor Antagonists

2.1K
Muscarinic receptor antagonists, also known as antimuscarinic agents, are a class of bronchodilators used to treat asthma, although they are more commonly used to treat COPD. They work by inhibiting the action of acetylcholine (ACh), a neurotransmitter, on muscarinic receptors found in the airways.
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...

Cholinergic Antagonists: Pharmacokinetics

1.1K
Cholinergic antagonists—such as antimuscarinics—are available in oral, topical, ocular, parenteral, and inhalational formulations. Most antimuscarinics are oral formulations,  while scopolamine is available as a topical patch, and ipratropium and tiotropium are available as inhalation aerosols or powders. Atropine, tropicamide, and cyclopentolate are topically instilled in the eye. Most antimuscarinics are lipid-soluble and readily absorbed from the gastrointestinal tract and...

Cholinergic Antagonists: Pharmacological Actions

1.9K
Antimuscarinic drugs block muscarinic receptors in multiple systems, including the gut, eye, smooth muscles, respiratory tract, cardiovascular, and central nervous systems. They produce similar effects with varying selectivity depending on the specific agent and tissue. Here are the key pharmacological actions of antimuscarinics:
Gastrointestinal Effects: Antimuscarinics reduce gut contractions, increase gastric emptying, and slow intestinal transit. They partly inhibit gastric acid secretion...

Cholinergic Antagonists: Therapeutic Uses

1.7K
Antimuscarinic drugs have various therapeutic applications by inhibiting parasympathetic stimulation in different systems. Here are the key therapeutic uses of antimuscarinics:    
Respiratory Tract: Ipratropium, aclidinium, and tiotropium treat asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD). They protect against bronchoconstriction caused by irritants like cigarette smoke, sulfur dioxide, and ozone. They also help reduce nasopharyngeal...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

2.3K
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Summary

Substandard antimalarials are prevalent in six African and Asian countries. Falsified antimalarials were found in two countries, while monotherapy antimalarials remain available despite WHO warnings.

Area of Science:

  • Global Health
  • Pharmaceutical Sciences
  • Medicinal Chemistry

Background:

  • Antimalarial drug quality is a significant public health concern, particularly in malaria-endemic regions.
  • The Artemisinin Combination Therapy (ACT) Consortium's drug quality programme investigated the prevalence of substandard and falsified antimalarials.
  • Previous efforts by the World Health Organization (WHO) to curb the sale of oral monotherapies have had limited success.

Purpose of the Study:

  • To disseminate the findings of the ACT Consortium's drug quality programme.
  • To discuss the public health impact of falsified and substandard antimalarial drugs.
  • To review strategies for improving drug quality surveillance and health system capacity.

Main Methods:

  • Purchased over 10,000 antimalarial samples using representative sampling in six malaria-endemic countries.
  • Conducted laboratory analyses to assess the quality of purchased antimalarial samples.
  • Reviewed data on the prevalence of falsified and substandard antimalarials and monotherapies.

Main Results:

  • Substandard artemisinin-based combinations were detected in all six countries studied.
  • Falsified antimalarials were identified in two of the six countries (<8% prevalence).
  • Antimalarial monotherapy tablets were still found to be available in some regions.

Conclusions:

  • Substandard antimalarials pose a widespread threat to malaria treatment efficacy across multiple countries.
  • The continued availability of falsified and substandard antimalarials necessitates strengthened regulatory and surveillance systems.
  • Addressing the challenge requires a multi-faceted approach involving quality control, health system strengthening, and regulatory action.
